"I know most of our pets are part of the family, and I try and do my best to treat them with respect and love.  My philosophy is to create an environment, where both the owner and their animal companions feel secure and trusting.  We try and make every visit friendly and as stress and pain free as possible.  The bond we have with them is an unbreakable one. As a fellow pet owner and lover, I cherish meeting and greeting every pet as it comes in the door.  If I could talk to the animals, I would want them to feel reassured that their proper care and good health is my number one priority.  I always welcome feedback, and continue to love what I do!"

Dr. Rosner also assists Sonoma Wildlife Center with caring for injured wild birds, foxes, raccoons, etc. Dr. Rosner also treats and welcomes caring for injured wildlife.

Uri, Candy Striper

RIP 1993 - June 2011

Uri was with Dr. Rosner ever since he came from Pets Lifeline.  He came to be neutered and we just couldn't part with the little fluff ball. He was a special kitty and is missed by staff and clients alike.  He has a special place in all our hearts.


RIP 2001 - March 7, 2017

Max came to us from a client who could not longer care for him. He is about 15 years old and loves to hang out on the reception desk greeting all the pet parents that come in. Max and his house mate Bandit have cross over the rainbow bridge. They both will be missed.
