Dr. Patrick Kalenzi

Amazing service. Knowledgable, trust-worthy, and super friendly. You can tell the staff love their jobs and each animal you bring to them. They don't use fear to upsell or make you spend $$. I have never been to such a hospitable clinic. My personal vet is Dr. Kellermeyer and she ROCKS. But each staff so far have been off the charts. go here, keep it simple.


My cat was presenting some unexplained vomiting and the clinic had me bring him in first thing, without an appointment, even though they were booked up and very busy for the day. They were incredibly kind, helpful, and thorough in their check up, and explained everything to me. After sending us home with some medicine and some food to help with his digestion, they called to check in on how he was doing the next day. Above and beyond care.


My favorite vet I’ve been to and I’ve been to a lot of vets. Dr. Kellermeyer is literally the best. I feel like the whole staff talk to me so straight forward and practical and really care about my dogs and not just making money (which I’ve experienced at other vets). They only prescribe or do test if I need them. The entire team is awesome and I feel like I could be friends with them and not just like I’m dealing with a doctor. They take care of my babies (and my babies are difficult).
