In the past 4 years in Frederick, we have made exciting improvements to the care we provide hip and knee replacement patients. I have assembled a comprehensive team that is committed to you having a great outcome and patient experience.
In 30 years in orthopedics, I worked in 3 different hospital systems in Central Pennsylvania before coming to Frederick. I helped many patients avoid surgery but I still performed over 5000 surgeries, including 2000 revisions. This extensive experience and continual self improvement allow me to help my patients with an excellent understanding of how to avoid surgery, when surgery can help, and how to deal with the complications that occur with surgery.
