10 years ago Dr. Mark Dales did surgery on my leg which I was diagnosed with Leg Calf Perthesis Disease and I now ride horses and am a normal senior in High school. Thank you so much

Dr. Mark Dales is WONDERFUL! When my first son, Zachary, was born in March 1997, he had severe club FEET. The pediatrician recommended Dr. Dales and he was the best thing that happened to a new mom with a "sick" baby! Zach was put in cast at 5 days old and we saw Dr. Dales weekly to change them until his surgery in October. My son had to have another surgery just on his left foot at 4 and he is now playing High School Football. Thank you Dr. Dales! Children's is lucky to have you!
