More Information

Throughout my career emphasizing neurological rehabilitation and musculoskeletal care, I've witnessed both the remarkable capacity of the human body to heal and the profound impact of illness on individuals and families. These experiences inspired me to focus not only on treating illness, but on preventing it and preserving long-term health.

My father's battle with glioblastoma made brain health deeply personal. A five-time marathon runner, he embodied resilience and perseverance, inspiring the philosophy behind Marathon Wellness.

My professional and personal experiences led me to pursue advanced training in integrative medicine, lifestyle medicine, metabolic psychiatry, clinical genomics, and cognitive health.

Today, I combine conventional medicine with integrative and functional medicine approaches to deliver personalized, whole-person care that supports healthy aging, brain and mental health.
