Dr. Alexander Hahn specializes in treating conditions of the hand and wrist as well as injuries from the shoulder to the fingertips. He treats common issues such as carpal tunnel, trigger finger, and arthritis as well as complex trauma and fractures requiring reconstruction.


Dr. Hahn chose to go in to hand surgery because of the opportunity to help people in a way that impacts their ability to live, work, and play. He understands that patients use their hands in all aspects of their lives, so no matter how seemingly small or big the issue, if it is important to the patient, it is important to him, too.


Dr. Hahn says, “I believe in treating the person in front of me, not just the condition or injury. By understanding who my patient is and what they need to do with their hands and arms, I can help come up with a treatment plan that works best with each patient, whether it is non-operative or surgical. There are many structures that make a hand function such as bones, muscles, tendons, ligaments, nerves, and blood vessels, and as a hand surgeon I use all aspects of my training to keep the hand working. This may mean using microvascular techniques, arthroscopy, joint replacement, or complex fracture repair.”


Dr. Hahn is a proud Maryland local, and is excited to come back to serve the community he grew up in. Dr. Hahn returns to the University of Maryland and R Adams Cowley Shock Trauma Center where he completed his orthopaedic training. After residency, he completed a hand and upper extremity fellowship at the renowned Indiana Hand to Shoulder Center to provide comprehensive upper extremity care to his patients. A former collegiate lacrosse player, he now enjoys golfing, snowboarding, and hiking with his wife and their dog.
