Meet Our Care Team
  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

Dr. Kailey Beckman grew up in Temecula, California and let us tell you, we are beyond thrilled that she joined our team last year in October! (When you see her congratulate her on her one-year anniversary with us!) While Dr. Beckman is fairly new to our team, she has been a veterinarian for three and a half years. Dr. Beckman completed her undergrad schooling at UC Davis and then graduated with her Veterinary degree from Western University. We love her creative, artistic nature! Chances are if you’ve met her- you know how much she LOVES all things Disney. She not only enjoys visiting Disneyland but she also makes stunning custom Mickey Mouse ears in her free time! When she isn’t at work or Disneyland she is usually home with her boyfriend, Anthony, watching movies or going out hiking. Dr. Beckman is a verified cat lover, she adores her three feline family members, Merlin, Archimedes, and Henry. She also has a cute little chameleon named Little Dude! Dr. Beckman is amazing with surgery and has a special interest in feline medicine. Everywhere she goes she spreads pixie dust and laughter, we are so appreciative of her magical energy!

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 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.

Brenda is a Rialto native and recently joined our team in April of 2021. She is our resident self-proclaimed thrill seeker!

While at work you can often find her cuddling puppies and spending lots of time bonding with our boarded patients. 

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.

Lexy is one of the smiling faces behind our social media platforms. Although you may not see her often, her loving presence shines through to all of us here and to those who have talked with her online. Lexy has been with RAH for five years and while her role with us has changed due to her health, we have loved and supported her all the way through her journey. Lexy’s love for animals began at an early age through watching her neighbor provide love and food to stray animals. Through finding and helping stray animals together, Lexy and her neighbor Wendy became family. Just like our many team members, she loves and appreciates all of the different bonds that animals can help create. Even though Lexy is pretty introverted these days, she loves to play boardgames with her friends! She knows how to play over 300 different games and out of all of them her favorite game is called Five Tribes. (Can you believe she doesn’t know how to play chess?!)
