Dr. Lydia Sun, MD looks past the symptoms to the biology underneath — advanced diagnostics and individualized, functional-medicine treatment plans that help you feel like yourself again.
Dr. Sun provides comprehensive labs and diagnostics that pinpoint what's actually driving your symptoms and chronic conditions — then translates those findings into a treatment plan built for your metabolism, genetics, and body. If you've been told your labs are "normal" but you still don't feel right, functional medicine is built for exactly that gap.
Our goal is a comprehensive, functional-medicine plan that optimizes your health while reducing or eliminating the symptoms holding you back. You're an active participant in your own care, with a plan you actually understand.
