Dr. Grant Dunbar
Owner and Medical Director
From an early age, Dr. Dunbar discovered his love for animals as he frequently brought home any stray or abandoned animal. This passion evolved into spending time after school and on the weekends at his father’s hospital developing the skills needed to take care of the animals he cared so much about.
He continued to follow his passion by pursuing a Doctorate degree at Western University of Health Sciences in Pomona, California. Dr. Dunbar then went on to complete an internship program at Animal Emergency Medical Center in L.A. focusing on critical care, surgery and internal medicine.
After spending his postgraduate years working as an emergency veterinarian, general practitioner and surgeon, he became the owner and medical director of Chino Hills Animal Hospital. Dr. Dunbar looks forward to providing you and your beloved pet with the quality of care he has worked his life towards perfecting.
Dr. Theresa Brauer
Dr. Brauer was an animal-loving child with dogs, birds and hamsters; thus, she isn’t surprised when people bring in every type of furry animal to her. She attended undergraduate and veterinary school in her home state at the University of Illinois where she met her husband who is also a veterinarian.
She has been practicing at this hospital for many years and enjoys the long-term relationships and trust she has built with clients. She feels gratitude that owners have trusted her as she helps them and their many pets. Outside of work, Dr. Brauer enjoys traveling, hiking and birding with her husband and has been an avid yoga practitioner for over 10 years.
Dr. Kaylee Otterson
Dr. Otterson is excited to help you and your furry pets whether dog, cat or pocket pet. She completed her undergraduate degree in Animal Science at Cal Poly Pomona and graduated with her Doctorate of Veterinary Medicine from Midwestern University in Glendale, Arizona. As a veterinarian, she looks forward to strengthening the human animal bond by educating clients in the many benefits of preventative medicine.
In her free time, Dr. Otterson enjoys being with her husband, her daughter, and her Pitbull, Beesly. She also shares her home with a Leopard Gecko called Jimothy. (Can you tell she’s a fan of The Office?) When she’s able to enjoy a moment or two alone from the busy veterinary life, Dr. Otterson can be found reading, golfing and listening/watching anything true crime.
Dr. Gabriella Hipp
Being influenced by nature documentaries and animal conservationists such as Steve Irwin and Jane Goodall, Dr. Hipp found her calling in the veterinary field at an early age. Since then, her path was clear. She pursued her undergraduate degree in Animal Science with an emphasis in pre-veterinary at Cal Poly Pomona and graduated with her Doctorate of Veterinary Medicine from Western University. During that time, Dr. Hipp worked with a zoo assisting in wildlife rehabilitation. Now, her primary interests are exotics and emergency medicine, but she is always willing to help any pet in need.
Although Dr. Hipp envisions a long veterinary career, she hopes to transition careers in the future to become a veterinary professor. Between examinations and surgeries, Dr. Hipp can often be found teaching the next generation of animal lovers and future veterinarians alike. However, when she’s away from the office, she spends as much time as possible reading and playing basketball with her son, AJ, while her canine BFF, Mason, provides moral support.
Dr. Elyanne N. Ferrer Yulfo
Dr. Ferrer was born and raised in Carolina, Puerto Rico and attended Royal (Dick) School of Veterinary Studies at the University of Edinburgh, Scotland. Shortly after graduating, Dr. Ferrer moved to California with her two cats, Joseph and Nico. And although she loves all animals especially her two kitties, her true passion resides with goats and sheep who have helped to shape the veterinarian she is today. Hence, she hopes to continue growing as a veterinarian and learning about ways to help and improve the life of our animals including supporting the small ruminant community towards the betterment of the industry.
During Dr. Ferrer’s free time, she enjoys playing tennis and mingling with friends as they admire the latest art installment in town or finding the next great adventure. A fun fact many may not know is Dr. Ferrer is an artistic individual having personally learned how to stain glass. Being so versatile and dexterous, Dr. Ferrer has also built and mounted various vintage table lamps in her spare time. She is definitely a vet of many trades.
Dr. Tierra Tyson
Growing up in the Bay area of northern California, Dr. Tyson could always be found around animals, but her furry little pup, Gypsy, and her horse, Rascal, hold a special place in her heart as her first patients. It is with their unconditional love and support she continued her personal and professional passion as a veterinarian. She later obtained her Doctorate of Veterinary Medicine from Western University of Health Sciences and continues her dedicated endeavor to nurture the human animal bond.
When she has a moment alone, Dr. Tyson is never far from the animals she loves. With a horse and two pups anxiously waiting back at home, she enjoys every waking moment riding her trusted companion or hiking with her two dogs. A break away into mother nature is just what the doctor ordered for this incredible veterinarian!
Dr. Jayme van ’t Riet
Dr. van ‘t Riet is highly passionate about preventative medicine, animal welfare and the human animal bond. She has graduated with her Doctorate of Veterinary Medicine from St. George’s University and finished her fourth clinical year at Washington State University. However, being a huge advocate for those who have no voice has ultimately steered her through the veterinary field and drives her to continue educating herself in modern veterinary medicine and teaching future veterinarians alike.
Having grown up in Southern California, Dr. van ‘t Riet is an avid nature lover and enjoys exploring the California country with her two faithful canine companions, Pasha and Zuma. But you can’t keep this veterinarian’s heart away from the wonders of the world as she will gladly take any and every opportunity she can to travel the world and experience its many different culinary delights.
