Dr. Tony Mathews, MD, MPH — a quadruple board-certified Endocrinologist and Longevity Medicine specialist at Sequoia Medical 360 in Bronxville, NY, known for his proactive, relationship-centered approach to optimizing long-term health and performance.
My Story — My Reason
The Call That Changed Everything
The call came unexpectedly: my father had suffered a heart attack. As a medical student, I understood the anatomy and the statistics—but nothing prepares you for watching someone you love become a patient. He survived. Many are not as fortunate. That moment forced me to confront a deeper truth about modern healthcare: crisis is often the first symptom.
The conditions that shorten lives—heart disease, metabolic syndrome, stroke—rarely appear suddenly. They develop silently over years. By the time the system reacts, the window for meaningful prevention is often gone.
Facing My Own Health Risks
My awakening wasn’t just professional. It was personal.
Despite my training, I wasn’t living the principles I taught. Between long hours, chronic stress, and putting everyone else first, I reached 200 pounds and felt the consequences: declining energy, rising metabolic risk, and early insulin resistance.
I realized I was on the same trajectory as the patients I was trying to save. So I made a commitment:
I applied everything I knew about metabolism, hormones, and cardiovascular prevention to my own physiology. Over time, my energy returned, my metabolic markers improved, and my health trajectory changed. But the most meaningful change wasn’t physical—it was identity.
I realized health isn’t just information. It’s guidance, partnership, and the courage to change your trajectory with someone at your side.
That personal struggle, and the journey it continues to shape, is woven into the DNA of Sequoia Medical 360.
Why I Founded Sequoia Medical 360
From Personal Risk to a New Model of Care
I knew there had to be a better way.
My father’s heart attack, my own risks, and my personal health journey pushed me toward prevention and shaped every step of my professional path. After earning a Master’s in Public Health, I completed Internal Medicine residency and fellowships in Preventive Cardiology and Endocrinology, Diabetes & Metabolism—fields that form the foundation of metabolic health, cardiovascular risk reduction, and longevity.
My ongoing work on my own health keeps me grounded in that mission. Rebuilding my energy, resilience, and metabolic markers reminds me that lasting change is never one moment. It is a continuous practice.
I created Sequoia Medical 360 for people who share that commitment. Individuals who want to stay ahead of their risks, invest in their long-term health, and pursue vitality with intention.

“Partnering with Dr. Mathews has been one of the most meaningful
decisions I’ve made for my long-term health.”
I can confidently say that Sequoia Medical 360 is the future of medicine. Having a doctor who is both an expert clinician and a personal health consultant is a game-changer. This is what true, personalized care feels like.
For the first time, I feel like I’m receiving true whole-person care. I never feel rushed—I feel heard and respected. With his support and guidance, I’ve already lost 20% of my weight—and feel more energetic than I have in years.
For years, I put my health on the back burner to build my business. Working with Dr. Mathews was a pivotal moment—his proactive approach helped us uncover a previously unknown health condition. This is the type of partnership everyone needs to finally take control of their health.
The best part of working with Dr. Mathews isn’t just the 70 plus pound weight loss—it’s the education. He helped me optimize my lifestyle, so the results are sustainable. I now feel confident and in control of my health for the long term.
