About

Dr. Julianna Lindsey delivers precision health optimization for high-performing adults. Her practice serves a small membership panel, far fewer than the thousands a conventional doctor manages. That focused roster gives each member thorough, unhurried care.

Dr. Lindsey holds board certification in Internal Medicine and brings over 20 years of clinical experience to the practice. She pairs that clinical depth with executive leadership experience at Fortune-level companies and a background in entrepreneurship. Her team uses AI-enabled analytics through the proprietary Lumenytics platform, which Dr. Lindsey co-founded. Every member receives comprehensive annual testing, a personalized longevity plan, and direct 24/7 access to Dr. Lindsey. Services span functional medicine, bioidentical hormone optimization, peptide therapy, cardiac evaluation, genetic screening, and mindfulness meditation.
