Dr. Marx is an absolute stud!!! I had a very positive experience and was very impressed with Dr. Marx and the staff at HSS! At first I was pretty hesitant about the procedure, however Dr. Marx was quick to reply to emails and provided simple and clear answers that put me at ease come surgery day. The ACL reconstruction went great and as expected the recovery took time. I've been wanting to give praise to Dr. Marx and his staff at HSS for their service that has helped me continue my active lifestyle and improved my quality of life tremendously.
