Beyond Concierge Medicine — THE FAMILY HEALTH OFFICE
You Manage Everything at a High Level.
Your Health Deserves the Same.
Most healthcare is handled one appointment at a time, across several doctors, with no one holding the whole picture. Sequoia Medical 360 is a specialist-led practice in Bronxville where one physician holds the full picture of your health and manages a clear plan with you, year after year.

What Happens When No One Holds the Full Picture
Six excellent doctors can still add up to six separate opinions and no single plan.
Care often starts late. Conventional healthcare is built to respond after symptoms appear or labs come back flagged. By then, the best window for prevention has narrowed.
Action waits for a diagnosis. Risk is easiest to change early, while it's still quiet.
The coordinating falls to you. The appointments, the results, the conflicting advice, and the quiet worry that something important is slipping through.

Built for Families Who Want a Long-Term Plan for Health
Dr. Mathews saw the same pattern for years, in his patients and in his own family: capable people left to coordinate fragmented care on their own.
He built Sequoia Medical 360 so one physician could hold the full picture. Families plan their finances with that kind of continuity. Their health deserves the same.

The Plan: How It Works
Here's what the first year looks like.
Step 1 — The Introduction
A short, private conversation about your goals and whether the practice is the right fit. It goes both ways.
Step 2 — The First 90 Days
A comprehensive, longevity-focused examination. It begins with a first visit of about two hours and includes advanced blood work, body composition, a fitness assessment, and a nutrition strategy. When appropriate, after discussion, it can include screening whole-body MRI and multi-cancer early detection. Everything comes together into one clear plan.
Step 3 — The Year Ahead
Regular check-ins with one specialist who knows you, adjusting the plan as life changes. Your other doctors stay in the loop, with your permission. Each year starts with a new baseline.
An executive physical gives you a snapshot. Sequoia Medical 360 gives you one specialist who holds the full picture and manages the plan with you, year after year.
