Arthritis | Bone & Joint (Orthopedics) | Knee & Joint Surgery | Orthopedic Surgery | RoboticsA patient’s journey through the arthritic process of the hip and knee is a varied one, and I take pride in developing a treatment plan tailored to the patient’s specific needs and goals. This patient centered care perspective allows the patients to participate in their own treatment process. I believe in exploring conservative forms of treatment for arthritis first before surgery is considered as an option. When conservative treatment has failed and the timing is right for the patient, we will explore the option of total joint replacement surgery. I enjoy taking the time to really get to know my patients as I feel this helps me to provide a personal level of care that patients can really appreciate.
As an orthopedic surgeon for St. Luke’s University Health Network, I treat a variety of musculoskeletal conditions. However, my subspecialty provides the opportunity to focus on the treatment of hip and knee arthritis
I am a board certified orthopedic surgeon who subspecializes in the treatment of adults with hip and knee osteoarthritis, post-traumatic arthritis and deformity and avascular necrosis. I perform total and partial joint replacement procedures, revision total joint replacement, and complex reconstruction procedures.
I attended medical school at the Philadelphia College of Osteopathic Medicine, where I learned that structure and function are dependent upon each other and to treat the patient as a whole. After medical school I completed a five-year residency in orthopedic surgery at Philadelphia College of Osteopathic Medicine. During residency I experienced the importance of restoring a patient’s motion and function, ultimately allowing them to participate in the activities that bring them enjoyment and happiness. This led me to pursue a fellowship in adult reconstructive surgery at the Florida Orthopaedic Institute in Tampa, FL. During this year, I furthered my skills in the field of partial and total joint replacement, revision joint replacement, complex reconstruction procedures, and robotic assisted joint replacement surgery.
I am an active participant in the American Osteopathic Association, American Osteopathic Academy of Orthopedics, American Academy of Orthopedic Surgeons and the American Association of Hip and Knee Surgeons.
I joined St. Luke’s University Health Network in 2016, and I have enjoyed being back in the Lehigh Valley area. I have always considered this area as my second home. I am proud to be the Network Director of the Orthopedic Robotics Program and the Director of Adult Reconstruction at the Warren Campus.
During my personal time, I enjoy spending time with my wife and kids as well as playing golf. I am a car enthusiast who enjoys watching and attending Philadelphia Eagles, Phillies and Sixers games. E-A-G-L-E-S… EAGLES!
