Dr. Jeffrey A. Creswell, Owner

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 owner veterinarian at Rialto Animal Hospital since February 1982 and has been our fearless leader, mentor, and supporter of all.  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. 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 joined our team as our second full-time associate 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, kitties Jordan, Gurley, and MeowMeow.   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. Heidi Schroer-Newell, Owner

Dr. Schroer was born in Berlin, New Hampshire and grew up in Southern California. For as long as Dr. Schroer can remember, she has always loved animals and knew that becoming a veterinarian would be her path in life. She received her undergraduate degree in 2006 from Cal Poly, Pomona and also worked at Rialto Animal Hospital for a year before starting veterinary school. In 2011, her dream of becoming a veterinarian came true when she graduated from the University of Minnesota with her Doctorate in Veterinary Medicine and joined our RAH family as our third veterinarian. She fast became a beloved doctor, team member, and friend to all.

Today, she is one of our partners at Rialto Animal Hospital and serves as our Chief Medical Director. She is an enthusiastic surgeon and thrives on challenging surgical procedures and learning advanced techniques. Her other professional interests include dentistry, preventive medicine, and (of course!) mentoring both recently graduated and aspiring veterinarians.

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 daughter Audrey and son Zeke.  Dr. (Dr. Creswell's 4th & 5th grandchildren!) understandably takes up most of his free time these days! 

Dr. Kailey Beckman

Dr. Beckman grew up in Temecula, California and let us tell you, we are beyond thrilled that she joined our team in October 2020!  Dr. Beckman completed her undergrad schooling at UC Davis and then graduated with her Veterinary degree from Western University in 2018.

We love her creative, artistic nature! Chances are if you’ve met her- you know how much she LOVES all things Disney.

When she isn’t at work or Disneyland, she is usually home with her loves (her kitty cats!), watching movies or 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!

Initially planning on being a veterinary technician, when covering a shift for a receptionist one day at her previous animal hospital, she realized that she LOVED helping both pets AND their people! And so her career as a stellar lead CSR began! Before joining our RAH family in 2020, Genevieve had already been in the industry for 5 years and with her vast knowledge, natural compassion & people skills, within six short months our team knew she was perfect for leading our CSR team to new heights in customer care!  

When she is not greeting you here with her warm smile and friendly hello, she loves spending time with her kiddos and her four-legged pack at home or on the trail, being ‘one’ with nature hiking, being crafty, and enjoying the magical world of Disney(land)!

P.S. She would be hard to beat in a karaoke contest… this girl can SING!

Sam

We are THRILLED that Sam is a part of our Customer Service team!! Some of you may recognize her.... because you've trained with her!

She got her start as a puppy raiser training service dogs and also has experience in therapy work.

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 husband and her Golden Retriever.

Sadly Sam had to say goodbye in late 2020 to her precious boy, Levi. Levi made sure someone would take care of his girl though. Sam now has another golden boy named Kit to adventure with.
