About Vet

I have practiced small animal medicine for almost 20 years, and have worked in a variety of settings, from busy city clinics, to animal shelters, to suburban practices. I currently own my own practice, offering both house calls and in-clinic visits. I enjoy giving pet owners the facts they need to make informed decisions, and if we don't know all the facts, I'll tell you that too! :) My most common request is from pet parents who have been given a diagnosis by their veterinarian, but would like the problem more clearly and honestly explained, and to understand all of their options. This includes anything from mild chronic diseases to end of life decisions.
