Dr. Landesfeind

Dr. Rachel Landesfeind

Dr. Landesfeind originally started with Hamilton Animal Hospital as a kennel attendant when she was a teenager. She continued to work here during summer breaks while she earned her bachelor's degree at the University of CA, Davis, and again when she earned her DVM at the same university. It was clear we weren't going to get rid of her easily, so when she graduated in 2007 we let her come back as a vet! She and her patient husband live with an assortment of weird little dogs, and look forward to acquiring more.

Dr. White

Dr. White was born and raised in Northern California. She moved to Indiana for vet school at Purdue University, and ended up in Philadelphia doing emergency medicine for 5 years before deciding the cold weather was for the birds. She moved to Orange County in 2017 where she continued work as an ER veterinarian for another 5 years. Recently, Dr. White decided to take a leap into general practice and took the job as medical director for Hamilton Animal Hospital.

In her spare time, Dr. White enjoys spending time with her fiancé (also a veterinarian), hiking with her dogs (Chase and Dora), snuggling with her cat (Kenya), working out, traveling, reading, and trying new wine and food. Despite having two dogs, she is definitely a crazy cat lady, and her love for kitties is part of what drove her to become a veterinarian.
