Fabulous Dr. Wallach and Sharon. The dream team!

5 stars Customer since 2015

Living in a multi pet household requires a lot of care and having such a wonderful vet to guide and care for my two cats and one dog has been invaluable! We are an older couple who values the conservative approach to pet care that Dr. Wallach provides. He is always prioritizing the best, most gentle care with the most conservative plan of action when diagnosing the problem with our pets. We appreciate that so much. Vet care can be so costly and Dr. Wallach is always fair in pricing. He is top notch with his care and explains everything so thoroughly to us. We cannot rave enough about this practice of wonderful people including Sharon, our wonderful office manager. If you don’t go to University Animal Hospital, you’re simply missing out on the best!!!!

Dr Wallach has been our vet for over 40 years. He is always very pleasant & caring and takes time to address all our needs. Even our dog gets so excited to see him.

Dr. Wallach has been my veterinarian for almost 30 years. I’ve always found him to be kind, compassionate and thorough with the care of my dogs. He always takes the time to listen to my questions and provide explanations in detail; I never feel rushed.

A shoutout to his veterinary assistant, Sharon, who is always caring and kind.

It’s very clear that they both love what they do; it’s not just a “living” to them.

The University Animal Hospital’s Dr. Marc Wallach consistently gives our pet excellent, professional care. We have brought all our pets to him for the past 40 years and have always been extremely happy with the excellent attention and care our pets have received.

Caring and knowledgeable

Our Riley was experiencing a little pain and we weren’t sure why. Dr. Wallach examined him and found that it was a lower back issue and prescribed medication to alleviate his pain. Riley also had his yearly checkup and had all his tests, shots and nails clipped. Dr. Wallach takes wonderful care of our precious pup (although almost 11years old) and we are always grateful for the care and attention he gives Riley and our family.
