Weight health is complex, but your care shouldn't be. As a specialist in obesity and cardiometabolic medicine, I provide thoughtful, medically grounded treatments tailored to your unique biology.
Because I have my own personal experience with weight, I lead with empathy rather than stigma. I founded Navigate to help patients move through the evolving world of metabolic medicine with a trusted partner and a clear roadmap.

Outside the Exam Room
I believe the goal of health care is to give you the physical freedom to pursue what you love. For me, that means staying active as an avid traveler and scuba diver. These passions serve as a daily reminder of why I do this work: I want to help my patients maintain the health they need to explore their own worlds.
My commitment to staying informed also extends to my interests in personal finance and global logistics. I’ve been featured in Business Insider discussing financial independence — a reflection of my belief in identifying what’s important and living intentionally.
