About this clinic

Brenda Marshall MD, a functional-medicine clinic in San Diego, offers individualized treatment for hormone imbalance, thyroid dysfunction, and chronic fatigue through comprehensive lab-based assessment. The practice specializes in peptide therapy, NAD IV therapy, and hormone-replacement protocols, alongside weight-management programs featuring semaglutide and tirzepatide. Gut-health evaluation and detoxification support are integrated into initial workups, and treatments are sequenced according to lab findings rather than applied standardly. The clinic emphasizes root-cause identification and serves patients seeking to optimize metabolic function and address age-related decline. Telehealth options are available throughout California.

Dr. Brenda Marshall is the best. I am 75 years old. I have been seeing her for 2 years and feel better than I have for 40 years. She is incredibly knowledgeable. I call her the captain of my medical ship. I highly recommend her.

Dr. Marshall has given me a much improved quality of life in just 2 1/2 months. I have had GI issues that were a quandary to doctors for two decades and Dr. Marshall “ figured it out!” I also averaged 3-4 hours of sleep and now I can say I’m close to 7 now. I am beyond grateful!!
