Dr. Wanniarachchi brings a unique and comprehensive background to the field of podiatric surgery and foot and ankle care. She earned her Bachelor’s degrees in Kinesiology and Women’s & Gender Studies from the University of Wisconsin–Milwaukee, where she also distinguished herself as a Division I cross country and track athlete. This athletic background, coupled with her academic foundation, ignited a passion for biomechanics and lower extremity health, leading her to pursue a career in podiatric medicine.

Dr. Waaniarachchi received her Doctorate of Podiatric Medicine from Rosalind Franklin University and subsequently completed rigorous surgical residency training at OSF St. Katharine in Dixon, Illinois. Throughout her education, she actively participated in podiatric research, contributing to numerous projects and presented her findings at a national conference. Notably, she was awarded 2nd place at the American Podiatric Medical Association (APMA) National Conference for her research poster: “Prophylactic Sural Neurectomy with a Closed End Conduit Following Calcaneal Fractures: A Retrospective Case Study.”

Demonstrating her commitment to advancing the field, Dr. Wanniarachchi also secured funding from the American College of Foot and Ankle Surgeons (ACFAS) to support the publication of her manuscript, “Single-Stage Talectomy and Tibiocalcaneal Arthrodesis for Rigid Post-Polio Equinocavovarus Deformity,” currently in the publishing process. Further solidifying her position as a rising leader, she was recently selected for the prestigious APMA Emerging Leaders Program.
