Dr. Kellman’s expertise in identifying root causes, combined with thorough testing, allows him to accurately diagnose and treat patients.

He pioneered "Microbiome Medicine," being the first to recognize the microbiome's crucial role in overall health. I understand your frustration with not feeling well and not getting better. I share your desire to get to the root cause of the problem. As a pioneer in functional medicine, my approach incorporates cutting-edge technology, the latest advances in natural medicine, and the science of how nature heals. My training in the philosophy of science and my years of experience as an M.D. have enabled me to take holistic and functional medicine to a whole new level. As a result, I can offer you a unique and powerful treatment plan that can transform your health…and your life.

The TRH Stimulation Test is one of the most important tools in a doctor’s toolbox — and one that, unfortunately, many practitioners (even in functional medicine) don’t offer.

If you’re struggling with fatigue, weight gain, brain fog, or mood changes — and your doctor keeps telling you your thyroid numbers are “normal” — don’t stop there. You deserve real answers.

I urge you to dig deeper. This test can reveal what standard thyroid panels miss and help uncover the true root cause behind why you still don’t feel well.

Think your thyroid is fine but still feel off? Book your consultation and ask for the TRH Stimulation Test — link in bio.
