How likely are you to recommend Dr. Theiss?

(Select your rating)
Dr. Theiss is the best orthopedic surgeon. He truly cares about his patients, listens to and respects their parents, and works hard to make sure the patient has the best care. Every specialist he has sent us to has been amazing. Dr. Theiss has walked us through some very scary and challenging situations and has rejoiced with us when my son overcame those challenges (better than expected, too! Thanks to Dr. Theiss and those he sent us to).
