Dan joined Sports Medicine & Joint Replacement Specialists in 2010. Since his arrival he has been an important part of the clinical team. Dan provides patient care through office visits, surgical assisting and hospital rounds.


His interest in Orthopedics was first sparked as an athlete in college and was later solidified with his Orthopedics rotation during graduate school. “I have found Orthopedics to be both an exciting and rewarding field where we can see the work we do make a real impact in our patients' lives.”


Additionally a background in psychology has given Dan a unique prospective on patient care. “What we do is so much more than just treating the broken bone or arthritic joint. As it is important in understanding what impact the patient’s disease has on their daily lives. My role as a physician assistant affords me the opportunity to provide care on a personal level, a role I enjoy.”
