Who treats you

Physician-owned. Clinician-led.

The Hormone Clinic is a physician-owned California practice and the third member of The Clinic family, alongside The Injection Clinic and The Concierge Clinic. No private-equity roll-up, no anonymous telehealth pool: two named clinicians whose credentials you can check.

Evgeny I. Tsimerinov, MD, PhD

Medical Director · practice owner

Dr. Tsimerinov is board-certified by the ABPN in Neurology (2007) and Clinical Neurophysiology (2009), both actively maintained, and serves as Associate Director of Neurophysiology at Cedars-Sinai. He is a Fellow of the American Academy of Neurology and the American Clinical Neurophysiology Society, with research published in Science Translational Medicine and the Journal of Neurology, Neurosurgery & Psychiatry.

As owner and medical director, he sets the practice's clinical standards — including this line's defining rules: FDA-approved medications only, physiologic dosing, no pellets, no compounding.

How we practice

The standards behind the program

  • Evidence first. We prescribe to guidelines and published evidence, tell you plainly where evidence is thin, and don't sell hope by the vial.
  • FDA-approved only. No compounded hormone blends, no pellet implants — see our HRT page for the reasoning.
  • Published pricing. Every fee on the pricing page before you ever call.
  • One family, whole picture. Hormones, midlife joint and tendon problems, and metabolic care — coordinated with our sibling practice, The Injection Clinic, when a joint or tendon needs treating directly.
