★ 5★ 4★ 3★ 2★ 1Dr. Mary is fantastic! Our old man German Shepherd has strong feelings about pretty much everything, but Dr. Mary and her staff are excellent and manage him very well. He's been seeing her for years as we don't trust anyone else to deal with his occassional attitude and plethora of allergies. There's never a wait as staff are always running on time, address all our needs/concerns, then get us out quickly. Highly recommend.
April 07 · Kimberly GarguiloDr Leister has taken care of all my dogs better than any other Vet I have been to I now live out of state but still try to bring my dogs to see her as often as possible because I know that I will be treated with respect.
July 06 · TIMOTHY SUREAUSimply the best! Thank you Dr. Leister and team 🤍🐾
April 29 · Sophia CrisafulliVery rude answering staff, and not taking new patients? How is an animal hospital not taking in patients? If you are that over filled you need to be changing the way things are working coming from someone who worked in vet med for 4 years and just recently left due to the LACK of empathy from anyone
June 26 · Alyssa JadeBeen using Dr. Leister for over 10 years and I have nothing but wonderful things to say about her and the entire staff. They care for my babies as if they were their own. They are patient, kind, thorough, understanding, and knowledgeable. They are also very affordable. We will be sad to leave this office due to moving out of state. I highly recommend this veterinary clinic 200%.
