Robert Zimmerman, M.D.

Robert O. Zimmerman, M.D. is an Internal Medicine Physician specializing in Pulmonary and Critical Care Medicine with 12 years in private practice.

Dr. Zimmerman, aware of the growing demand for a natural alternative to synthetic hormone replacement therapy, began to seek out options available.

In his search for a safer, more effective way of treating patients with sometimes debilitating hormone deficencies he discovered subcutaneous bio-equivalent hormone pellets to be the superior choice in hormone replacement therapy.



Dr. Zimmerman has implemented subcutaneous bio-equivalent hormone therapy into his practice to better treat his patients and others who suffer with the sometimes devastating effects of hormone deficencies.
