CEO and Medical Director
Being a physician is a distinct privilege—one that allows me to restore health, improve lives, and empower patients to take control of their well-being. There’s profound meaning in helping someone heal and guiding them toward a stronger, more energized future. At the core of my practice is the belief that exceptional care begins with listening. By understanding each patient’s symptoms, lifestyle, goals, and concerns, we can deliver a truly personalized path to optimal health.
After completing medical training, I held several leadership roles across both private practices and federally qualified health centers in California. As a former Medical Director, I’ve overseen multidisciplinary teams and helped expand access to care—earning commendation from Los Angeles County for dedicated service to public health.
During this time, I began to see the shortcomings of conventional medicine, especially in the treatment of hormone-related conditions. Patients with clear symptoms were often dismissed because their lab results were “within range.” But optimal health isn’t defined by averages—it’s defined by how a patient feels, functions, and thrives. That disconnect inspired me to develop a more effective, patient-centric solution.
I founded Alpha Hormones® to bridge that gap—offering advanced, evidence-based therapies in hormone optimization, peptide therapeutics, and regenerative care. Our platform is designed for convenience and clinical precision, helping patients regain energy, improve performance, and extend their healthspan with therapies grounded in science and personalized to their needs.
At Alpha Hormones®, we’re redefining what it means to age well. By supporting hormonal balance, metabolic health, and cellular resilience, we help patients feel better—not just today, but for the long term.
My greatest specialty is my unwavering dedication to my patients. I believe that exceptional care begins with compassion, attentive listening, and a commitment to evidence-based medicine. You deserve the highest standard of care—and that’s exactly what you’ll find in my practice
