Meet Our Doctors!

Dr. Jeffrey A. Creswell

Dr. Creswell was born and raised on a farm in Iowa (a good ol' Iowa boy!).  He is a graduate of Iowa State University College of Veterinary Medicine 1981.  In June of 1981, he moved to California to begin practicing small animal medicine.  He has been a full-time staff veterinarian at Rialto Animal Hospital since February 1982.  We can't say enough good things about Dr. Creswell... caring, compassionate, and committed to giving his patients the best possible care, he'll leave many of you asking if he see HUMAN patients (many of our clients have already asked!!)

Dr. Creswell's hobbies include spending time with his family, golfing, and reading. He especially loves being the best Grandpa in the world to his three grandsons and two granddaughters!

Dr. Creswell's patients include dogs, cats, rabbits, and rats. (Unfortunately, he is highly allergic to hamsters and guinea pigs...Sorry!



Dr. Shannon T. Juarez

Dr. Juarez, a Rialto native, knew at the young age of ten that she wanted to become a veterinarian.  Her aspirations were no surprise to her family and friends because of her compassion and dedication to all living creatures great and small.  She completed her undergraduate and masters degree in animal science at the University of California, Davis.  Prior to attending veterinary school, she worked in the dairy industry as a marketing representative.  Dr. Juarez completed her veterinary degree at Western University of Health Science, College of Veterinary Medicine in May 2007 and has joined our team as a full-time staff Veterinarian.  However, Dr. Juarez is no stranger to our practice.  During her four years at veterinary school, she worked during her summer and holiday vacations at our hospital.   In her spare time, she enjoys camping, swimming, cycling, playing tennis, and spending time with her husband and four-legged kids, dogs Bridget and Andre and her cat Jordan.   Dr. Juarez also has a huge heart and another passion... she has traveled to Ghana, Africa with a team of professionals and has worked to improve the lives of the underprivileged people of Ghana. She is a "perfect fit" here, with the same admirable qualities that we love so much in Dr. Creswell.

Dr. Juarez's patients include dogs, cats, rats, hamsters, gerbils, guinea pigs, rabbits and chinchillas.



Dr. Heidi Schroer-Newell

As long as Dr. Schroer can remember, she has always loved animals and knew that becoming a veterinarian would be her passion and livelihood. She received her undergraduate degree in 2006 from Cal Poly, Pomona, and her dream came true in 2011, when she graduated from the University of Minnesota with her Doctorate in Veterinary Medicine. She is an enthusiastic surgeon and thrives on challenging surgical procedures and learning advanced techniques. Her other professional interests are in internal medicine.

Dr. Schroer was born in Berlin, New Hampshire and grew up in Southern California. Prior to starting veterinary school, Dr. Schroer worked with our team at Rialto Animal Hospital for a year. We are very proud to say that she also spent a year on the tiny island of Pohnpei, one of the Pacific Islands of Micronesia, where she taught English and Biology to the native children. We feel honored that Dr. Schroer is working by our side as our doctor, and are confident that you will love her as much as we do (and we love her a lot!!)

Dr. Schroer loves the mountains and the beach, especially palm trees and sand. Her interests include hiking, beach trips, playing with her two dogs and cat, family time, and spending quiet moments with her husband, Mike, and their two absolutely ADORABLE son and new baby girl.

Dr. Schroer's patients include dogs and cats.



Dr. Andrea Wolf

We were thrilled to welcome our 4th Veterinarian back in late 2013. After an extensive search for a Doctor that would be the perfect fit for our hospital, we finally found her!  (And she's even bilingual in Spanish!!!)

Growing up, Dr. Wolf always knew she wanted to be a Veterinarian. She fulfilled that dream in 2011 when she graduated from the University of Minnesota, College of Veterinary Medicine. Dr. Wolf focuses on delivering high standards of medicine and compassionate care for her patients. Her professional interests include surgery, internal medicine and dentistry and she is a strong advocate for gentle feline handling.

Dr. Wolf is enthusiastic, gentle, patient and passionate in her care for pets and their people. She enjoys outdoor activities such as hiking, cycling, and swimming. You can find her in our hallways singing and always has a big smile on her face. She is a self-proclaimed “book worm” and a fearless chef.  And the BEST thing our resident 'chef' cooked up was her new baby girl, Malina!!! Congratulations to their wonderful family!

Dr. Claudia Lau

All we can say is that we feel EXTREMELY blessed to find and welcome our 8th DVM to join our RAH family! After a nationwide search, we found our perfect new veterinarian was nearly in our backyard!

Dr. Claudia Lau was raised in San Gabriel, CA but has become familiar with the Inland Empire after residing here since 2010. She earned her Bachelor of Science degree in Biological Sciences from UC Riverside. After graduation, she worked at a veterinary clinic where her interest and love for dermatology began. Dr. Lau's lifelong dream became a reality when she earned her Doctorate of Veterinary Medicine from Western University of Health Sciences. As a Fear-Free Certified Professional and owner of a very sassy feline, she recognizes the stress that patients and clients may experience during veterinary visits and hopes to incorporate various fear-free techniques for all patients to RAH.

In her free time, Dr. Lau enjoys playing the piano for her two cats Molly and Mason, hiking, or spending the day at Universal Studios. She is a proud Hufflepuff!

 Dr. Scott Creswell

No, your eyes are not deceiving you... Dr. Scott is Dr. Creswell's son! We are so happy and proud to have two generations of "Creswell" working at Rialto Animal Hospital and we have no doubt that you will be just as delighted!

Throughout his childhood and early adult years, Dr. Scott grew up watching and helping his dad at Rialto Animal Hospital. He soon realized that he had the same calling to veterinary medicine and decided to attend Western University of Veterinary Medicine so he could work alongside his dad as a veterinarian. In March 2017, his dream was realized as he became our 5th doctor to join our team. Dr. Scott is an integral part of our dental health team and continues to pursue education about new and advanced techniques to bring to the dental team in order to ensure our patients are being given the best dental care possible. He also is passionate about surgery.

Dr. Scott is a self-professed "foodie" and while some of his hobbies include "anything in the mountains", hiking, and playing basketball... enjoying his beautiful toddler girl and baby boy (Dr. Creswell's 4th & 5th grandchilden!) understandably takes up most of his free time these days. 

Dr. Kailey Beckman

We must have been wishing on the right star when we found out that our "Sensational Six" team of doctors would soon be growing to a "Supercalifragilisticexpialidocious SEVEN" in October 2020!!! (That was fun to spell! And keep reading... You'll understand! :)

Dr. Kailey Beckman grew up in Temecula, CA where her love for animals flourished as she grew up with dogs, cats, birds, horses, donkeys, goats, chickens, and tortoises. She holds a Bachelor of Science in Animal Science from U.C. Davis. In 2018, she received her Veterinary degree from Western University of Health Sciences. Her professional interests includes surgery and feline medicine as she understands the trials that our families go through. She doctors her own sweet kitty, Merlin, at home as he battles both diabetes and GI lymphoma.

In her spare time, and when not spending her time doting on her three cats Merlin, Archimedes, and Henry, Dr. Beckman likes traveling and crafting, which includes making EXTRAORDINARY custom Disney ears so she and her friends can wear them when going to one of her favorite places... Disneyland. YES, that's right! Another Disney fan that is excited to be bringing a bit of 'pixie dust' and magic to RAH and our families! We are thrilled to welcome Dr. Beckman into our RAH family!

Dr. Katherine Fischbach

How did we get so lucky?!! This amazingly talented DVM has joined our SENSATIONAL doctor team as of June 2020! We are so very excited for our families to meet her and experience the wonderful care she provides to all her patients (and our pet parents!)

Dr. Fischbach appears on paper as an Indiana transplant; however, she was actually born in Los Angeles. Her interest in veterinary medicine was piqued early, so consequently her childhood dog was subjected to frequent 'exams'. She earned her undergraduate degree at Washington University in St. Louis. Afterwards, she returned to Indiana to attend veterinary school at Purdue. Growing up in Indiana, Dr. Fischbach's ambition was to someday return to California. In June 2020, she made her dream a reality by joining our team here at Rialto Animal Hospital.

Dr. Fischbach's areas of interest include providing medical care to pets of all life stages, opthalmology, and exotic pets (especially guinea pigs). When not at the hospital, she enjoys cooking, hiking, and entertaining her cat Hobbes. 

Meet Our Care Team!!

Our Client Service Representatives are the first smiling faces you will see when you visit Rialto Animal Hospital. They are first and foremost in the care of you and your pets and provide assurance of the care you will receive during your visit. 
 They are here to make you feel welcome and comfortable!


Lexy's beautiful smile will greet you at our desk and she is one of RAH's Chihuahua enthusiasts! While she is only a 'few years young' in the field of veterinary medicine, she has loved animals since she was a very young child. She decided to leave the world of management and joined our family to pursue her passion. Lexy just loves to snuggle on our furry little patients, so if you need a free hand when you are here (or even if you don't!), Lexy is always ready with open arms to help out and hold a fur-baby! Lexy is mom to two of her own fur-babies: Amelia and Atlas (yes, both are rescued Chihuahuas and we are so happy that she saved these little lives!) 

On her days off, you can find Lexy at the local dog parks or walking her doga around her neighborhood. She also has a deep love for video games, Tim Burton movies, and the famous Snoopy and Woodstock. 

If you've been a long-time friend and client of Rialto Animal Hospital, you know Diana! She has been dedicated to making a difference in the lives of pets and their people since 1995 as a customer service representative. Diana has been the friendly face and voice of our hospital for over two decades and the knowledge she has to share is immeasurable! After helping her patients and pet parents, Diana goes home to spend time with her husband and four "kitty kids": Clicker, Joy, Star, and Lilly. 

During her free time, Diana loves spending her time in the fresh brisk mountain air, doing all things crafty, cooking for her husband, and baking the best-tasting pies, fresh salsa, and lemon bars we've ever tasted (which makes us really love to support her baking/cooking hobby!)

Jenny is another immensely talented lady that is a part of our Customer Service Representative team and will be one of the very first to greet you with her brilliant smile, positive energy, and a "How can I help you Hon?" She graduated from Cal Poly University, Pomona in 2006 with her Bachelor's degree. She has had over 10 years of experience in the veterinary field. In her words, "I have always had a passion for animals since I was young. Animals speak to you and heal your soul no matter what language you speak"... we couldn't have said it better Jenny!

When not helping our families that come to Rialto Animal Hospital, Jenny enjoys hiking, yoga, and writing poetry (she has even wrote and published a book, and is currently working on book #2!) Her most precious time at home is centered around her new (yes, two-legged) baby girl, Amara.

We are THRILLED that Sam joined our Customer Service team recently!! Some of you may recognize her.... because you've trained with her! Sam has always been an animal lover and knew she wanted a career centered around them. She graduated with her Bachelor's Degree in Healthcare Administration from Loma Linda University and has also earned her Certified Professional Dog Trainer (CPDT-KA) title through the Certification Council for Professional Dog Trainers. She has been training dogs for nearly 12 years and loves every minute of it! She got her start as a puppy raiser training service dogs and also has experience in therapy work. Sam has extensive knowledge in dog obedience and behavior and has helped many pet parents by teaching individual lessons and group classes. Sam is most passionate about training because she can use the talents she has acquired to help dog owners create better bonds with their four-legged best friends, making a difference in the lives of both people and pets. So dogs... if you're having trouble with your humans, bring them in to talk to Sam!!

When she is not working, Sam enjoys hanging out with her family, friends, and all her pets (dogs, a cat, rabbits, fish and a turtle!), crafting/sewing, going to Disneyland (Yes!! Another Disney fan!), and going on off-roading adventures with her fiance and her Golden Retriever, Levi.

Abigail's huge smile says it all!! Another of our Customer Service Representatives, Abigail is always ready to greet our families with a beautiful smile, friendly welcome, and will make you feel right at home! Abigail has had a love of animals her entire life and she says she is grateful that she "gets to work in a place where she can pet puppies and kittens all day"! Although new to the Rialto Animal Hospital family, Abigail has over 10 years of experience working in the Agriculture/Animal Science field. She has raised and shown various livestock animals which led her to pursue her Bachelor's degree in Animal Science from the University of Minnesota. She graduated in 2007 with an emphasis in pre-veterinary medicine. After graduating college, she moved back to California and settled here in Rialto where she lives with her 'awesome husband' (they are so cute together!), their two Great Danes, and mini rex rabbit.

When not at work, Abigail is usually on a plane traveling somewhere or planning her next excursion. She enjoys reading classic novels and has a love of interior decorating and design.

Each of our amazing veterinary assistant and technician team each bring unique background and experience to our hospital.  Most have had formal training, either through an accredited technician program or a University. Over 60% of our team are college grads, with nearly early 40% of our team having earned four-year college degrees. We are also very proud to say that we have had some of our staff apply (and be accepted) to veterinary school! These people work hard, and they are devoted to doing their best for our patients and their people! 


Lisa Norkunas, RVT and Hospital Director has been with Rialto Animal Hospital since 1995. As a child, she and all those around her knew it was "her calling" to work with animals and work in the field of medicine. She graduated with Magna Cum Laude from Cal Poly Pomona in 2003 and remains a member of the Golden Key Society. She received her Registered Veterinary Technician (RVT) certification shortly after graduating, accepted our hospital manager position in June 2003, and became the hospital director in December 2005.

"The Boys" will always be close to their hearts and live on in the hearts of the many lives they touched over the years. Today, her family has two more Golden Retrievers, Ryder and Gunner. They also recently became a horse family with the additions of their Appaloosa "Summer" and Kentucky Mountain horse, "Lexi".

When Lisa is not working, she loves spending time with her husband, her children (Kayla, Nathan and Ella), and her four-legged kids. She is a 'country girl' at heart that enjoys riding horses, country music, and dancing (good luck keeping up!), boating, wakeboarding, traveling, hiking, working out, Disney-everything, reading, playing softball.

Alondra Luna, Hospital Manager and veterinary technician joined the Rialto Animal Hospital family in 2003 after working several years for the San Bernardino Humane Society. From an early age, she knew that caring for the furry family member was her passion. When at work, you can be sure that she strives for improvement, growth, education and provide both clients and pets with the best care.

She received her Bachelors of Science in Pre-Vet Medicine (Animal Health Science) from Cal Poly Pomona in 2006 and a few short years later became assistant manager in 2009.

During her spare time, she enjoys the outdoors, new adventures, doing crafty things or DIY projects, baking and decorating yummy cakes and cupcakes, and being the best dog mom to her "only child", golden retriever Roxy (pictured)

Unfortunately, she and her baby girl said goodbye after 14 wonderful years of companionship, but her memory will forever be present in the hearts and minds of all who knew her. 


Nicole joined our staff in September 2007 and is quite versatile in her roles at Rialto Animal Hospital. Even though she has been seen helping out in the exam rooms and even at the front desk from time to time, she especially enjoys working our treatment room, where she helps with procedures, surgery, dentistry, and our hospitalized patients. She has taken great strides in her role in the treatment room and continues to go above and beyond to ensure your furry family members receive outstanding care.

Nicole and her husband of 17 years enjoy dinners out and spending time with their nieces and nephews. Nicole is continuing the process of obtaining her RVT license! 


Elsa, a Registered Veterinary Technician (RVT) has been with us since 2004. She is a graduate of Cal Poly Pomona and is a valuable member of our team. When she is not helping our patients and clients, she is always studying to expand her knowledge. Elsa is detail oriented performs the many of our patient's dental cleanings. We're excited that Elsa has earned her RVT license, thanks to her dedication and hard work!

When Elsa is not tending to our patients at RAH, you can find her spending quality time with her greatest blessings in life... family and her children. She is very active, plays a wide array of sports (which she is GREAT at!), and keeps our team laughing with fun games around the hospital. She has even been known to bring in a ping pong table for some competitive fun and helps put softball games together for us. We are thankful to have her on our team (especially when we are PLAYING teams!:)



 Karla has been a long-time veterinary assistant (and now Registered Veterinary Technician, or 'RVT') of Rialto Animal Hospital, having joined our team when we were a lot smaller in 2007. And are we happy she did!!! Karla is a very special part of our growing family and we couldn't imagine this place without her bubbly personality, huge smile, and constant joking! Karla's always had a love for the animal industry, and has found that her true passion is dentistry, which she is AMAZING at! There are many happy, healthy smiles out there thanks to her hard work!

Karla has two Siamese mixes, Mugen and Soleil and a "problem child" Schipperke named Sierra (pictured). In her spare time she likes to create art of all kinds, listen to her husband's band play, and groom dogs.

He is a definite "people-person" and his personality is sure to have you wanting his help again and again! He is a self-professed "cat whisperer" and hasn't lost a whisker yet!

The majority of the time you can find her working as part of our dental team, helping treat and prevent periodontal disease. She believes that education, whether providing it to our clients or learning for herself, is the key to being the best advocate for her patients. Christina is always striving to learn new information and techniques in order to improve her skills and patient care. As a child Christina has always loved large dogs and is proud to have two giant fur-babies of her own, Zannah, a Newfoundland, and her big brother Bane, a Great Pyrenees.

Kristin continues to be a WONDERFUL addition to the RAH veterinary assistant team since hired in February 2017. Her gentle nature and love of animals was evident from the start. Kristin's experience at RAH has strengthened her love for veterinary medicine and has further motivated her to continue her education toward her goal of becoming a veterinarian. She is currently attending Cal Poly Pomona working towards her Bachelor's Degree in Animal Science. In her free time she loves reading, photography, and spending time with her two dogs Ginger and Gunner.

UPDATE!!! This amazingly talented lady has been accepted into and has started veterinary school! Can't say that we aren't hoping for her to return to us as part of our DVM team!! We wish her all the best and can't wait to see all she becomes!


Emily joined our family in 2017 as a patient care advocate. If your fur baby is staying/boarding with us in our "hotel", she is one of a very small, elite group of caregivers we have that is sure to treat your kid the prince or princess that they are! Emily aspires to grow within the veterinary field and is currently a senior at California State University, San Bernardino, majoring in biology and pursuing certification to become a Registered Veterinary Technician. When she is home, she loves on her own six canine fur babies: Ginger, Max, Mora, Mazy, Luna, and Marley. Emily also loves to pursue new adventures, loves to contemporary dance (she even used to dance at Disneyland and California Adventure!), and is also another one of our self-proclaimed "foodies", who enjoys trying new foods with her boyfriend.


Meet Stephanie! We were ecstatic when she joined our team as another 'elite' patient care advocate in January 2018 as she was finishing her schooling. She graduated from California State University, San Bernardino in June 2018 with a bachelor's degree in Biopsychology. Upon completion of school (we now have her full time!!), she has been training to work in exam rooms where we are sure she will impress you as much as she has impressed us with her beautiful personality, smile, and caring ways! The things she enjoys most about her career is working with such a supportive staff and getting to meet new fur babies every day. She says she fell in love with the veterinary field when her best friend (who actually works here too... thank you Emily!) introduced her to the job. After snuggling with her patients each day, she gets to go home to her own fur kids, Lady, Shei, and Mochi.

Erick is one of another of the "elite squad" of patient care advocates here and is currently attending CBU working toward his veterinary degree. Erick loves all animals and volunteered at local animal shelters for 3 years to learn as much as he could about his passion in helping animals. 

Erick enjoys video games, playing sports (especially soccer, volleyball, and football), and writing short stories and poems.


Aloha joined our patient care advocate team and we are so excited he did (and we're sure you'll agree with us when you meet him and see the loving care he provides to your fur-kids!) He is currently attending Carrington College to achieve his RVT license. He attributes his career choice to his grandpa who ran a ranch in Mexico. In his childhood, Aloha would help his grandpa tend to a wide variety of animals including horses, cows, sheep, chickens, cats and dogs. Aloha loved seeing how all the animals had a purpose on the farm and how much they meant to both of his grandparents. He knew that he wanted to work with animals and has been focused on growing his knowledge in the veterinary field ever since.

In Aloha's spare time, he likes to be outdoors, enjoys sports, spending time with his family and friends, and likes nearly anything and everything that revolves around art.
