“The staff is very friendly and it has my favorite vet (Dr Kelly) that used to be at the holistic Calabasas vet clinic before they closed. That is the main reason I went there, but feel good about everyone else I've met there. The animals I've seen there seem to be pretty calm and not as anxious as I typically see in the waiting room of other vets so they must pick up on the friendly nature of the place also.”

“I had an amazing experience with this office, starting with the initial call to coming in and meeting the staff and Doctor Siegel. My dog was a handful to say the least and I was never made to feel anything other than well cared for. I highly recommend!”

“As a retired veterinary technician, this is a very well organized hospital. The staff is very caring and the doctors are fantastic. Great with diagnostics, surgery, and are very informative. I have taken 3 dogs there for various medical reasons and also all three had dentals there, one of who was a major high risk for anesthesia and they did such a great job. The hospital has a great protocol with anesthesia and recovery which was very impressive. I thank them all for all they do.”

“Look no further if you're looking for a primary! I absolutely love it there, I had my first visit with my senior dog and all staff were extremely friendly and helpful. My dog gets nervous and has hated previous vets but he was so great with the vet here which was such a relief. Thank you all staff for taking care of my bubz.”

“Michael Siegel had been treating all my pets for years! When I first learned he was opening his own practice I couldn't be more excited for him. There is no one more deserving and I can't wait to continue my pets health care at his new facility.”
