Our Specialists

We are proud to be one of Baltimore’s first orthopaedic practices dating back to 1927 when pioneer orthopaedic surgeon Dr. Raymond E. Lenhard, began treating his first patients. Dr. Lenhard’s goal was to provide quality and compassionate orthopaedic care.

Decades later that attention to personalized care has brought generations of families to Orthopaedic Associates. Before retiring, John J. Fahey, M.D. reflected: “I treated three generations of patients. Many of these patients became my friends, not just patients.” The skilled physicians of Towson Orthopaedic Associates still believe in that philosophy today.
