Membership & Enrollment
Do you accept insurance?
The membership retainer is not a substitute for health insurance. We recommend all members maintain active coverage.
Yes. We remain in-network with Medicare and most major commercial insurers. We bill your insurance for medically necessary visits and standard labs, just as any practice would. The membership retainer covers what insurance does not: proactive longevity planning, integrated assessments like VO₂ max and nutrition strategy, and direct access to Dr. Mathews between visits.
What does the membership retainer cover?
The annual retainer covers physician-led strategy, integrated physiological assessments (body composition, VO₂ max, nutrition planning), ongoing direct communication with Dr. Mathews, and diagnostic oversight across the year. Laboratory testing, imaging, and procedures performed by external facilities are billed separately through your insurance or directly to you.
What makes Sequoia Medical 360 different?
Most practices are built around brief visits and isolated evaluations. Sequoia is built around continuity. You work with one physician who integrates endocrine, metabolic, and cardiovascular risk into a single coherent strategy, refined over time. The practice is deliberately small so that follow-through is proactive and decisions stay in sequence.
Who is this practice designed for?
Individuals and families who want a proactive, specialist-led health partnership rather than episodic treatment. Most of our members are founders, executives, and private wealth families who view health as essential infrastructure and want it managed with the same rigor as everything else in their lives.
How do I become a patient?
Visit our Request an Introduction page. Within one business day, you’ll receive a personal response to schedule a brief introductory conversation. No commitment until your first visit.
Can I enroll my spouse or family?
We encourage it. Metabolic health, nutrition, and sleep patterns are often shaped by the household environment. When families optimize together, adherence improves and results compound. Each membership remains an individual clinical partnership since your baselines are unique, but we coordinate timelines for family members so your household strategy stays aligned. If you plan to enroll as a family, note this in your introduction request so we can reserve capacity.
Is there a waitlist for membership?
Sometimes, yes. To maintain the depth of care each member receives, we cap our patient panel. If enrollment is full, you will be placed on a priority waitlist for the next available opening.
Care Experience
What happens during the initial consultation?
Your first visit is an unhurried 90 to 120 minute session focused entirely on your history, lifestyle, and goals. This is where Dr. Mathews builds your clinical baseline before any advanced testing begins. It is the start of a structured 90-day initiation designed to turn scattered information into a coherent strategy.
How often will I see Dr. Mathews?
Typically every 3 to 4 months for comprehensive strategy sessions. When risk factors are being actively managed, visits may be as frequent as monthly. Between visits, you have direct access to Dr. Mathews via text, cell, and the patient portal.
What kind of testing or assessments are included?
Your membership includes the core assessments needed to build and maintain your clinical baseline:
* Body composition analysis (research-grade InBody, performed in-suite)
* VO₂ max and strength assessments (coordinated with our clinical partners, initial and biannual)
* Nutritional strategy sessions with our Registered Dietitian, when your clinical picture calls for it.
Can you coordinate care with my existing specialists?
Yes. Dr. Mathews integrates outside specialist input into your overall strategy. Whether your specialists are at Columbia, NewYork-Presbyterian, or elsewhere, we ensure your metabolic and cardiovascular care stays aligned with your broader health goals. When specialty intervention is needed, we provide warm introductions to vetted clinical partners and stay involved throughout.
Billing & Administrative
What payment options are available?
Membership is supported by an annual clinical retainer. Payment options are discussed during the introduction call. We accept ACH and major credit cards.
Can my company or employer pay for my membership? Can I use my HSA or FSA funds?
Yes. Our services are structured as qualified medical expenses, which enables funding through HSA, HRA, FSA, and MSA accounts. Many members also use executive wellness stipends or direct employer funding. Self-employed members may fund their retainer on a tax-deductible basis. We recommend confirming your specific options with your tax advisor or plan coordinator.
Are there any surprise or hidden fees?
No. The retainer covers all integrated assessments outlined in your agreement. External labs, imaging, and specialty medications are billed by the performing facility or through your insurance. You will always know what to expect.
How are medical emergencies handled?
For any medical emergency, call 911 or go to the nearest emergency room immediately. Our practice focuses on long-term strategy and does not provide emergency medical services. For urgent but non-emergency concerns, you can reach Dr. Mathews directly for guidance and coordination.
