Not only is Mark Heard an amazingly friendly doctor he is a miracle worker on knees. After my right knee was butchered from 3 prior surgeries on my meniscus and Acl by a not so thoughtful Doctor, I got referred to Dr. Heard and i couldn't be more thankful. Dr. Heard took a look at my knee assets it, saw that my previous donor graph was all wrong and didn't take place, and shouldn't of been done that way to begin with. He took my patellar tendon and used it for my ACL instead . He also did my left knee when I eventually blew it out the same way, and they have felt great ever since. I have had no problems with them. Of coarse the occasional soreness but that's normal. He was so personable was able to nail down the reasoning why I have such bad knees and able to suggest what I needed to do different to avoid further injuries. with his surgeries, Im not limited to what I can do so much as I was before. He is amazing. I recommend him to anyone with knee injuries that still want to live their lives not stressing about their knees constantly, to people who were active prior to injury and want to be active after reconstruction with little to no problems. Dr. Heard..... I mean it would be a pleasure to see you again. But I don't think I'll have too. Thanks for giving me, semi strong legs again:) you rock.
