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.

At Sequoia, medicine is not a transaction. It is a year-round partnership dedicated to the rigorous, long-term management of your physiological assets

The Sequoia Standard

A new model for people who want depth, continuity, and true prevention.

This is not concierge primary care or a one-day, spa-like physical. It is longitudinal, specialist-led prevention designed around you.

Specialist-Led, Not Generalist-Led

You receive specialist-level expertise at every visit — endocrinology, metabolism, and preventive cardiology woven together. No handoffs. No fragmentation. Every decision is integrated and intentional.

Longitudinal Clinical Strategy

We move beyond the one-day executive physical. At Sequoia, health is managed through year-round action and accountability, turning advanced data into a continuous, stepwise strategy for your future.

Integrated Physiological Management

Your hormones, metabolism, and cardiovascular risks are interconnected systems—and we treat them that way. Nothing is siloed; every metric is coordinated to support your metabolic resilience and longevity.

Precision Preventive Diagnostics & Monitoring

We identify risks far earlier than standard labs detect—tracking the metrics that drive long-term health, including metabolic function, inflammation, VO₂ max, and vascular risk.

Coordinated Health Optimization

Data alone does not change health; execution does. You receive coordinated guidance with your training and nutrition partners, ensuring your lifestyle strategies are as precise as your clinical labs.

Direct Physician Partnership

We maintain an intentionally small patient panel to ensure your story is never forgotten. Your care is directed by a physician who practices these principles daily to achieve elite metabolic health.

Is Sequoia Medical 360 the Right Fit for You?

Our work is most successful when both physician and patient are aligned in purpose, values, and commitment. Sequoia is designed for individuals who want to take an active, long-term role in their health — people who value depth, continuity, and a relationship with a physician who knows them well. But the truth is, this approach is not for everyone.

Our approach may not be right for you if you:

Prefer episodic care rather than an ongoing relationship
Want quick fixes instead of addressing underlying systems
Prefer a test-first or medication-only approach
Are looking for a one-day assessment without follow-up or continuity
View health as something to check once a year rather than cultivate every day
Prefer short-term goals over a long-term strategy
Prefer a generalist model instead of a deeper, specialist-guided approach to long-term health

Sequoia is an excellent fit if you:

Want a physician who focuses on longevity and integrates endocrinology, metabolic health, and preventive cardiology
Value true prevention — identifying risks early and managing them with intention
Prefer a relationship-based approach that deepens and evolves over time
Want clarity, direction, and a plan for your long-term health
Are ready to partner in your care, not just receive information
Appreciate a holistic, whole-person approach that connects hormones, metabolism, cardiovascular risk, sleep, nutrition, fitness, and stress
Are invested in performance, vitality, and a life defined by strength and purpose

If this philosophy resonates with you, you’ll see why one member described this care as a ‘game-changer.’

Thoughtful Care. Meaningful Outcomes.
