Jake Hare

Doctor of Veterinary Medicine

Dr. Jake Hare (we think his last name is awesome; don't you?!) grew up in Point Loma and decided he was going to be a Veterinarian during his freshman year of high-school. Dr. Hare actually started his career in veterinary medicine as a kennel assistant in 2004. He attended Cal Poly San Luis Obispo earning degrees in Biology and Modern Languages & Literatures before moving on to UC Davis' School of Veterinary Medicine. He completed an externship at the Franklin Park Zoo in Boston but ultimately decided to stick with companion animal medicine. After graduating in 2015, Dr. Hare returned to practice at the same clinic he worked as a kennel assistant before we were lucky enough to find him. Since joining RSDAH in June of 2017 Dr. Hare immediately became part of our family; adding to the already existing camaraderie here. Dr. Hare has special interests in surgery and neurology and has worked with organizations like Feral Cat Coalition and Rescue House. Away from work Dr. Hare enjoys reading, the beach, snowboarding and playing Ultimate Frisbee which he's been doing for 13 years. Dr. Hare currently shares his home with his kitty, Auri.

Dr. D



Rebecca de Castellanos

Doctor of Veterinary Medicine

Dr. Rebecca de Castellanos, Dr. D for short, was born in San Diego but did the majority of her growing up in Ann Arbor, Michigan. As a child she loved going to the San Diego Zoo and originally wanted to be a Zookeeper; which she did for 3 years in Texas! She changed her mind and set her eyes on becoming a veterinarian after taking part in a veterinary internship at the Howell Nature Center in Michigan. At Michigan State University she obtained her Bachelor's of Science in Zoology (with a minor in Spanish) before continuing on to the College of Veterinary Medicine there. After graduating she completed a year long internship at Washington State University's College of Veterinary Medicine. We were very happy to welcome Dr. D back to San Diego when she joined the RSDAH family in July of 2017. It didn't take long for us to bond with Dr. D because much like the rest of the staff here at RSDAH, she loves food almost as much as she loves animals. She frequently accents her lunch from home with McDonald's french fries(wave to her if you see her in the drive-thru!). Dr. D has special interests in cardiology and all exotic animal medicine but especially reptiles & fish. She has participated in externships at both the San Diego Zoo & Safari Park and done additional studies and work in rural Mexico with chickens, goats, cows and horses. Dr. D spends her time away from work with her husband and daughter and their Coated Xoloitzcuintli, Callejero. She enjoys cooking, reading and cross-stitch at home and when she can find a babysitter she enjoys traveling, tea tasting and Ballroom & Salsa dancing.
