Dr. Lirtzman is a fantastic person and an exceptional surgeon. We had previous experience with a different vet surgeon, different dog, who underwent knee surgery and never totally recuperated from it. With Dr. Lirtzman, I felt confident from the get go knowing my dog had the very best surgeon and opportunity for a long, active life as she was only 3 when the accident happened. I watched the surgery, and being a nurse, noted that the surgery was done in the exact same manner as human surgeries are. Dr. Lirtzman was unbelievably patient, answered all our questions and in general took such great care of our Sahara. I told Dr. Lirtzman that I wished I could find a human doctor with the same attributes he has. I flat out couldn't recommend a better, more qualified surgeon. If you love your dog(s) like we do, they're family, then you owe it to them to see Dr. Lirtzman.
