Description of Clinical Expertise
1dd My clinical practice focuses on complex foot and ankle reconstruction, particularly of the ankle and hindfoot. I am heavily involved in sports foot and ankle work, caring for high level athletes from high school to medical consulting for professional sports teams (including the Philadelphia 76ers, Flyers, and Union). I am also an expert in complex reconstruction, including salvage of prior surgery, including revision of prior fusions and ankle replacements.71
Description of Research Expertise
13d My academic passion is surgical ethics. I have worked or am working on ethical issues in bundled payments, opioid policy, limb reconstruction and amputation, and shared decision-making. I am also involved in clinical ethics consultation, as the co-chair of the Pennsylvania Hospital Ethics Committee.8
