 We want our patients to benefit from ALL that the highest level of veterinary medicine has to offer, not just what holistic medicine or traditional Western medicine can provide. We believe that integrative medicine offers the best tool, at the best time, for the health condition that is presented. And it offers the best options for wellness-focused care, too. At Knollwood Hospital for Pets, we would no more deprive you of the best that Western Medicine has to offer than we would neglect to tell you when acupuncture or chiropractic; laser therapy or homotoxicology; or even herbal therapy or a Bach Flower remedy would be in your pet's best interest.

I'm very thankful for the caring person you are and and for all the brilliant care my babies received from you and the entire staff over the years. Every day I had with Tara was a blessing and I thank you for helping me have a few more years. I hope you all know how very special you all are.

There is no place besides your hospital where I feel safe to say exactly what my Sophie means to me. I cried when I talked about her to you today ... But I know that Dr. Mitchell, and Sylvia, and your Nurses DO understand how important our pets are to us.

Knollwood is an AWESOME hospital, and I would HIGHLY recommend them to everyone. In fact, I DO recommend them, every chance I get! Everyone at Knollwood is friendly, professional and caring for both pets and humans.
