About
At Holtorf Medical Group in El Segundo, California, three physicians tackle complex, multisystem conditions that standard workups often miss. Dr. Kent Holtorf founded the practice after his own experience navigating undiagnosed Lyme disease, Babesia, Bartonella, reactivated viruses, and mold toxicity. That personal history shaped a clinical philosophy built on root-cause investigation and systemic thinking. The practice has since grown to twenty-three affiliate corporately owned centers and twelve franchises nationwide.
Dr. Moses Laufer brings deep expertise in thyroid optimization, hormonal health, and age management. Dr. Wayne Wightman contributes 35 years of experience treating endocrine dysfunction, chronic fatigue, and complex thyroid conditions. The team runs comprehensive biomarker testing every three to six months, tracking markers that routine care typically overlooks. Services span functional medicine, BHRT, peptide and bioregulator therapy, IV nutrient therapy, IV ozone therapy, EBOO therapy, chelation, and aesthetics. The practice offers both in-person and virtual appointments, and maintains a dedicated Veterans Appreciation Program. m. m.
