Welcome to Restore Health LLC

As a board-certified endocrinologist with well over 20 years in private practice (since 2003), I bring deep traditional expertise to functional endocrinology. I founded Restore Health LLC in mid-2025 to focus exclusively on root-cause care for hormone-related conditions — combining rigorous diagnostics with holistic, integrative approaches.

Education & Training

  • Medical Degree: Mount Sinai School of Medicine

Professional Background For over two decades, I’ve treated thousands of patients with thyroid disorders, diabetes, hormone imbalances, and cardiometabolic issues while educating local physicians, residents, and PA students. This foundation allows me to go beyond standard management — investigating genetic, environmental, lifestyle, and hormonal factors to restore true balance and vitality.

At Restore Health LLC, we specialize in:

  • Thyroid optimization (beyond “normal” labs)
  • Hormone health for men (testosterone, energy, libido, body composition)
  • Sustainable weight loss driven by endocrine factors
  • PCOS, diabetes, insulin resistance, and related concerns

Our cash-pay model ensures unhurried, personalized care without insurance limitations. In-office consultations preferred in Fairfield; HIPAA-compliant telemedicine available.

If you’re a driven individual committed to addressing root causes and achieving lasting wellness, I’m here to partner with you.
