Functional Healing by Harper MD was built on a simple conviction: people deserve answers, not just prescriptions. Led by Dr. Dan Spindler, our practice combines rigorous clinical training with decades of hands-on experience treating the conditions that leave patients feeling dismissed or hopeless. We've served over 3,000 patients across the country through our virtual practice, and every protocol we create is grounded in science and shaped by real clinical work.

Our team of physicians, practitioners, and coaches shares a relentless commitment to functional medicine—an approach that asks why, not just what. We specialize in weight loss resistance, autoimmune disease, type 2 diabetes, neuropathy, ADHD, and the full spectrum of chronic conditions where root cause medicine makes the difference. With advanced postgraduate education and a passion for restoring health, we're here to be your partners in achieving a natural, pain-free lifestyle.

We're not just healthcare professionals. We're advocates for a better way forward. If you've been told to live with your symptoms, we're here to prove there's another path.
