Meet our wonderful Doctor 

Dr. Diana Stiles is native to Southern California, having grown up in the nearby San Gabriel Valley. From the age of 9, she knew she wanted to be a veterinarian and passionately pursued her dream. She is a 2001 graduate of Colorado State University, College of Veterinary Medicine and Biomedical Sciences. Upon graduation from Veterinary School in 2001, she returned to Southern California to start her veterinary career. Her main interests include internal medicine and preventative care, and she especially enjoys being in the exam rooms talking with her clients. She is grateful for the many clients who have been with her for years, allowing her to be a special part of their pets' lives from their early years all the way into their senior years. She is excited to open Rancho West Animal Hospital and looks forward to continuing to provide high quality, compassionate care to the pets of the Inland Empire. Dr. Stiles also volunteers her time with a local dog rescue group and is an active member of the American Veterinary Medical Association. Dr. Stiles is married to her high school sweetheart, with whom she has three beautiful children. They also share their home with their 2 dogs, bearded dragon, and guinea pig. In her free time, she enjoys spending time 
with her family, camping, water sports, and reading.
