Dr. Grant Dunbar

From an early age, Dr. Grant Dunbar discovered that he had a love for animals; frequently bringing home any stray or abandoned animal that needed a home. This passion then evolved with him spending a majority of his 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, pursuing a Doctorate degree at Western University of Health Sciences in Pomona, California. Dr. Grant Dunbar then went on and completed 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 vet, general practitioner and surgeon, he has moved on to become owner and medical director of Chino Hills Animal Hospital.

Dr. Grant Dunbar looks forward to providing you and your beloved pet with the quality care he has worked most of his life perfecting.
