"Dr. Nace is phenomenal! I have been thrilled with the total knee replacement he did for me.... Within 6 months, I was running sprints again without pain. From the very beginning, Dr. Nace has treated me like I was part of his family.... I cannot say enough about how gifted he as an orthopedic surgeon! Additionally, he has great people skills and has built a tremendous team around him who also have encouraged and inspired me in my recovery. In my 61 years of life, I have never met any surgeon with his level of gifts and talent."
