About Us

Dr. Ryan McCally & Dr. David Hutcheson completed their surgical training together at the University of Missouri. They have extensive experience in all manner of orthopedic and general surgery, and they have particular experience in minimally invasive orthopedic surgery and total joint replacement. With their long history of working together, they bring a unique and innovative approach to caring for pets. Both Dr. McCally and Dr. Hutcheson will participate in every patient’s surgery. That means each patient has the benefit of having two experienced surgeons’ eyes and hands working together to provide the best possible surgical care. This unique approach is designed to reduce anesthesia time, lessen surgery time, provide better care, and result in fewer complications.
