My Story — Why I Do This Work

Curiosity Became Calling

In high school, I entered a NASA-sponsored science competition almost on a whim. To my surprise, my team won three consecutive national awards, designing experiments that launched aboard NASA rockets. I learned early that science isn’t just knowledge—it’s a tool to solve meaningful human problems.

That insight carried me toward engineering, and later, Brooklyn College EMS. Rising from trainee to Chief of Operations of a fully volunteer ambulance service taught me what no classroom could: behind every vital sign is a person who deserves to be seen.

I didn’t choose preventive care as an academic interest—I chose it because I saw how silently risk can build. Sequoia was built to catch that trajectory earlier, with more depth and continuity.

The Three Lenses of Sequoia

Standard training often forces physicians to view a patient through a narrow frame. My public health and dual-fellowship training gave me a wider one. Sequoia is built on three lenses:

1. Public Health (Systems Thinking)

Most care treats the symptom; public health treats the system upstream. I apply that mindset to the individual—auditing the “environment” of your physiology: sleep, stress, nutrition, training, and recovery—because that environment is where risk is created or reduced.

2. Endocrinology (The Metabolic Root)

Hormones and metabolism shape energy, body composition, inflammation, and long-term risk. Endocrinology taught me to identify early metabolic dysfunction—often long before standard thresholds are crossed—and to correct it with precision rather than generic advice.

3. Preventive Cardiology (Risk Stratification)

The absence of symptoms is not the absence of risk. Preventive cardiology trained me to go beyond “normal” ranges, using advanced interpretation and selective diagnostics to identify vascular risk early—while it is still modifiable.

Sequoia was built on one conviction:
Risk is a trajectory.
My work is to identify it early—and change it with you.

From Disillusionment to a New Standard

Even with this training, I found the traditional system wasn’t built to deliver depth or continuity. Visits were rushed, prevention was secondary, and the incentives rewarded throughput—not synthesis. Physicians were forced to choose between documentation and thoughtful analysis.

I knew there had to be a better way. So I built Sequoia as the alternative: a specialist-led partnership designed for longitudinal strategy, not episodic transactions.

Medicine, To Me, Is Not A Transaction

It is a relationship—one that unfolds over years, not minutes.

I founded Sequoia Medical 360 to restore what large systems too often lose: personal, precise, preventive care rooted in partnership.

This practice is for people who value depth, discretion, and long-term partnership—and want their health managed with intention.


This is the difference between having a doctor who treats you and a strategist who knows you.

My Story — Why I Do This Work

TM Mayor Marvin Cropped 819x1024

Curiosity Became Calling

In high school, I entered a NASA-sponsored science competition almost on a whim. To my surprise, my team won three consecutive national awards, designing experiments that launched aboard NASA rockets. What began as a science project became a formative moment: I realized that science wasn’t just knowledge — it was a tool to solve meaningful human problems.

That insight carried me toward Biomedical Engineering.

Everything shifted again when I joined Brooklyn College EMS, a fully student-run 911 ambulance service. What started as curiosity quickly became a calling. I rose through the ranks — from dispatcher to crew chief — and ultimately Chief of Operations.

Those years changed me. They cemented my desire to go to medical school and showed me the kind of physician I wanted to become.

They also taught me something no classroom ever could: that behind every vital sign is a person — scared, vulnerable, hopeful — who deserves to be seen.

It was through those experiences that I first imagined a future in emergency medicine and felt the meaning of being truly present for someone when it

It began with a phone call that changed everything — and a journey that changed me. My father had suffered a heart attack.

In medical school, I understood the anatomy and the statistics — but nothing prepares you for watching someone you love become a patient. In that moment, medicine stopped being theoretical. It became painfully real. I saw how much we wait until crises strike… how prevention is treated as an afterthought… and how differently care could look if we focused earlier, deeper, and more personally.

But my path toward medicine began long before that call.

Here, medicine is not a transaction. It is a year-round partnership with one purpose:
to help you Live Stronger, Live Longer, and Live With Purpose.

The Personal Turning Point

During medical school, my father’s heart attack reshaped my vision for what I wanted out of medicine. It made prevention feel personal, not theoretical — and it sparked a quiet obsession:

If we can identify risk early, why aren’t we doing more to prevent these events in the first place?

That curiosity led me down a rabbit hole of learning and re-evaluating my own risks. And what I found surprised me.

My labs weren’t normal and furthermore I carried elevated genetic risk for cardiometabolic disease.

I wasn’t just learning about prevention anymore; I was living it. And I began to realize how much disease evolves silently, long before it’s formally diagnosed. I weighed 200 pounds. My labs and genetics hinted at risks that weren’t obvious from the outside.

It made me question something fundamental: How can someone look “fine” on paper but feel completely different inside? Why does metabolic dysfunction begin long before it shows up on standard labs? Why does traditional medicine wait for disease before acting?

It was the first time I understood that health isn’t a snapshot — it’s a story, and if you read it early enough, you can change the ending.

That realization shifted the entire direction of my medical path. I became deeply interested in endocrinology, metabolism, and cardiovascular risk — the systems that ultimately determine long-term vitality. I pursued answers not only for myself, but for every patient living with unevaluated risk or who had ever been told, “Your labs are normal,” when they knew something wasn’t right.

TM Mayor Marvin Cropped 819x1024

After leaning into the science behind my own risks, I wanted to understand these systems with absolute depth. I pursued advanced training in Internal Medicine, Endocrinology, Diabetes & Metabolism, and Preventive Cardiology — along with a Master of Public Health at Columbia, focusing on population health and risk reduction.

But the deeper I went, the more clearly I saw the problem.Even in academic centers filled with brilliant and caring physicians, the system was structured around speed rather than depth. Appointments were short, follow-up was fragmented, and prevention was rarely integrated into long-term strategy. Metrics overshadowed meaning. And patients — especially those with subtle metabolic issues — slipped through the cracks because their labs looked fine.

The physicians I worked alongside weren’t the problem. The system was.It forced doctors into a model where they had to choose between time with their families and time with their patients, between documentation and thoughtful analysis, between checking a box and understanding a human being.

That disconnect stayed with me. I knew there had to be a better way to practice medicine — one rooted in depth, continuity, and true partnership.

Here, medicine is not a transaction. It is a year-round partnership with one purpose:
to help you Live Stronger, Live Longer, and Live With Purpose.

During medical school, my father’s heart attack reshaped my vision for what I wanted out of medicine. It made prevention feel personal, not theoretical — and it sparked a quiet obsession:

If we can identify risk early, why aren’t we doing more to prevent these events in the first place?

I became deeply interested in endocrinology, metabolism, and cardiovascular risk — the systems that ultimately determine long-term vitality. I pursued answers not only for myself, but for every patient living with unevaluated risk or who had ever been told, “Your labs are normal,” when they knew something wasn’t right.

Years of Specialized Training — and a Growing Disillusionment

After leaning into the science behind my own risks, I wanted to understand these systems with absolute depth. I pursued advanced training in Internal Medicine, Endocrinology, Diabetes & Metabolism, and Preventive Cardiology — along with a Master of Public Health at Columbia, focusing on population health and risk reduction.

But the deeper I went, the more clearly I saw the problem.

Even in academic centers filled with brilliant and caring physicians, the system was structured around speed rather than depth. Appointments were short, follow-up was fragmented, and prevention was rarely integrated into long-term strategy. Metrics overshadowed meaning. And patients — especially those with subtle metabolic issues — slipped through the cracks because their labs looked fine.

The physicians I worked alongside weren’t the problem. The system was.

It forced doctors into a model where they had to choose between time with their families and time with their patients, between documentation and thoughtful analysis, between checking a box and understanding a human being.

That disconnect stayed with me. I knew there had to be a better way to practice medicine — one rooted in depth, continuity, and true partnership.

WHY I FOUNDED SEQUOIA MEDICAL 360

After years of training and clinical practice, it became clear to me that the system wasn’t designed for the kind of medicine I believed in. The pace was too fast, the visits too short, the follow-up too fragmented. Prevention was fragmented, not integrated. And patients who needed depth were forced into a model built around volume.

I wanted something different — for myself and for my patients.

I wanted a practice where a physician truly knows the person in front of them: their physiology, their habits, their risks, their goals, and their story.

A practice where metabolic, endocrine, and cardiovascular root causes are explored before problems accelerate.

A practice where continuity isn’t a luxury — it’s the foundation.

I founded Sequoia Medical 360 to restore the kind of medicine that gets lost in large systems: personal, precise, preventive, and rooted in long-term partnership.

Medicine, to me, is not a transaction. It is a relationship — one that unfolds over years, not minutes.

Sequoia was built for people who want their health taken seriously, who value depth over speed, who want to understand their risks before symptoms appear, and who want a physician who walks alongside them — not just through illness, but through the pursuit of a longer, stronger, clearer life.

Sequoia reflects the kind of medicine I believe people deserve — personal, preventive, and rooted in depth. When I realized there wasn’t a model that fully aligned with that vision, I chose to create Sequoia Medical 360.

My commitment is simple: to deliver care with intention, precision, and partnership — and to walk alongside my patients in their pursuit of strength, clarity, and long-term health.

A Last Thought

At its core, my work is about partnership — understanding who you are, what you value, and how to help you live with strength, clarity, and intention. This is the medicine I believe in, and the commitment at the heart of Sequoia Medical 360.
