We have three kids all of who play soccer. They are ages 18, 15, and 9. Our daughter has been treated by Children's Orthopaedic twice, once for a broken arm and the other for two broken bones in her hand both due to sports injuries. Our son was also treated for a broken arm. In each case, we were tended to right away and given the best care. The kids were nervous but the staff and Doctors put them at ease. Their injuries healed perfectly and the follow up care was tremendous. We have since gone back with our other son for treatment on his knee due to sports camp. We are a sports family and there is no other place we would trust our kids to than Children's Orthopaedic!
