Functional Medicine Doctor in Greenwich, CT
Greenwich demands a higher standard — and so should your healthcare. If you’re a high-performing professional who has been told your labs are “normal” while still battling fatigue, brain fog, weight gain, or hormonal symptoms, you deserve a more rigorous answer than that.
As a board-certified endocrinologist with over 20 years of clinical experience, I offer Greenwich patients the precision of traditional endocrinology combined with the depth of functional medicine — from my practice, Restore Health LLC, located in Fairfield, CT, approximately 30 minutes from Greenwich via I-95.
My Fairfield office serves patients from Greenwich, Cos Cob, Riverside, and Old Greenwich seeking a specialist-level alternative to concierge primary care and telehealth-only hormone clinics.
Why Greenwich Patients Choose Me Over Local Alternatives
Greenwich has no shortage of wellness clinics, health coaches, and telehealth platforms offering hormone optimization. What’s rare is a board-certified endocrinologist with fellowship training at one of the country’s top academic medical centers who takes a root-cause approach.
I trained at Mount Sinai and completed my endocrinology fellowship at Montefiore/Albert Einstein under Dr. Norman Fleischer — one of the preeminent endocrinologists in the country — and Dr. Martin Surks, a world-renowned thyroid expert. That pedigree matters when your hormones, thyroid, or metabolism are complex.
What I investigate that others don’t:
- Thyroid function beyond TSH — Free T3, Free T4, reverse T3, and thyroid antibodies
- Hashimoto’s thyroiditis — the autoimmune root cause behind most hypothyroidism
- Mitochondrial function and energy production — cellular-level disruptions that explain fatigue conventional labs never catch
- Gut microbiome assessment when digestive, immune, or metabolic patterns point to an underlying connection
- Toxicology and environmental exposure testing — heavy metals, endocrine disruptors, and other factors that silently compromise performance
- Hormone optimization — testosterone, estrogen, and the complete picture
- Insulin resistance and cardiometabolic markers that predict problems years before diagnosis
Performance, Precision, and Root-Cause Medicine
High-achieving professionals don’t accept “good enough” in their work — they shouldn’t accept it in their healthcare either. Many Greenwich patients come to me after years of being told everything looks fine, only to discover an underlying thyroid disorder, hormone imbalance, or metabolic dysfunction that standard panels missed.
At Restore Health LLC, your initial consultation is 90 minutes. I review your full history, prior labs, lifestyle, and symptoms with the thoroughness that a 15-minute appointment simply cannot provide.
Common reasons Greenwich patients book with me:
- Persistent fatigue, brain fog, or declining performance despite healthy habits
- Thyroid symptoms dismissed because TSH falls within “normal” range
- Seeking a board-certified specialist — not a telehealth prescription service
- Complex hormone or metabolic cases that require true endocrinology expertise
- A second opinion from a physician with 20+ years of clinical experience
Board-Certified Endocrinology. Cash-Pay. No Compromises.
Restore Health LLC is a cash-pay, concierge practice. No insurance means no rushed appointments, no coverage-driven treatment decisions, and no 10-minute consultations. You receive my undivided attention and a level of diagnostic rigor that insurance-based medicine rarely allows.
