PATIENT STORIES
What Northern Virginia Patients are Saying
"
★★★★★
Dr Zachary Weidner is an amazing orthopedic surgeon. He replaced my right hip with perfection and professionalism. I asked him his advice on which surgery to pursue, and he gave me an honest straightforward recommendation with no hesitation. This resulted in the smoothest surgery I have ever experienced and I have had a lot of surgical work done. If you have the choice to go with Dr. Weidner as your surgeon do not hesitate and know that you are in the best hands possible. I was most amazed by the fact that it was virtually a pain-free surgery and recovery! Thank you, Dr. Weidner and God bless you!
