  • "January 4, 2018
    I was very pleased with the service here. My dog, Emmy, came in to get spayed and the whole thing was a great experience. She was up and running around just a couple days later and healed just fine. The price I paid was reasonable and the staff was very professional and courteous. I'll be a return customer for sure."

    My dog Lady Bird Johnson had a huge tumor in her abdomen. It was almost 3 pounds and connected to her spleen. Doc Riddell removed the tumor and spleen and for the first time my corgie wants to run! Love the staff and Doc Riddell is a rockstar to myself and Ladybird!!�"

    After reading some of these reviews I have to say I am dumbfounded..I have never had anything but wonderful things to say about both Dr Lange as a diagnostician who has always been spot on with his diagnosis. And Doc Riddle is always there to answer my questions. I have just today consulted him and he took the time to answer my questions and set my mind at ease. I think the quality of care at this facility is second to none."
