Dr. Shiv Goel, MD is a board-certified physician and the founder of Prime Vitality Care, a physician-led functional medicine and wellness clinic based in San Antonio, Texas, with telehealth services available to patients in all 50 states. Dr. Goel trained in internal medicine and functional and integrative medicine, and has spent his career building a practice model that treats the root causes of poor health rather than managing symptoms in isolation. His clinical philosophy is grounded in the understanding that hormones, metabolism, inflammation, gut health, and mental well-being are deeply interconnected systems — and that lasting health improvements require addressing all of them together. Prime Vitality Care specializes in physician-supervised GLP-1 medical weight loss programs using semaglutide and tirzepatide, bioidentical hormone replacement therapy (BHRT) for women, testosterone replacement therapy (TRT) for men, peptide therapy including Sermorelin, BPC-157, and PT-141, and comprehensive functional medicine consultations for patients with chronic fatigue, gut dysfunction, autoimmune concerns, and metabolic disease. Dr. Goel is a sought-after expert on the clinical application of GLP-1 therapies, the role of hormonal imbalance in weight resistance, and the future of physician-led telehealth medicine. He speaks regularly to the gap between what conventional medicine offers patients with metabolic dysfunction and what a root-cause, functional approach can deliver when the right diagnostics and time are applied. Through Prime Vitality Care's HIPAA-compliant telehealth platform, Dr. Goel brings the same standard of clinical depth and personalization to patients nationwide that San Antonio patients have relied on in person — with lab coordination through local Quest Diagnostics or CPL sites and all prescriptions compounded and shipped directly to patients.
