Frequently Asked Questions – Concierge Longevity Medicine

What is concierge longevity medicine?

Concierge longevity medicine is a proactive, personalized approach to healthcare that goes far beyond traditional primary care. We focus on extending health span, not just lifespan—optimizing your physical, cognitive, sexual, and metabolic health so you can look, feel, and perform your best for decades to come.

What makes Marshall’s approach different?

Our care model is:

Rooted in evidence and data: We utilize advanced biomarker testing, imaging, and diagnostics to deeply understand your biology.

Hospitality-driven: From 24/7 access to same-day appointments, our white-glove service redefines the healthcare experience.

Longevity-focused: We incorporate the latest in hormone optimization, preventative screenings, peptide therapies, biologics, and lifestyle medicine.

Comprehensively managed: We coordinate all care, including specialty referrals and advanced therapeutics, with oversight by Dr. Mullins and our team.

What is included in a longevity program?

Our programs typically include:

• A comprehensive executive physical
• Ongoing biomarker-driven assessments
• Tailored plans for nutrition, fitness, hormones, and supplements
• Access to peptide therapy, regenerative medicine, and performance optimization
• Unlimited direct access to your medical team for urgent or complex needs

How often will I be seen?

Our members are seen more frequently than in traditional care models—with quarterly in-depth reviews, personalized touchpoints, and unlimited virtual or in-person visits as needed. Our goal is to monitor, refine, and optimize your health in real time.

Can I keep my regular doctor or specialist?

Yes. We frequently coordinate with specialists and PCPs, and many of our clients use us as their primary care while others retain a traditional PCP for insurance-based services. We serve as your trusted medical advisor, guiding your care at the highest level.

Do you prescribe hormones or peptides?

Yes—when appropriate. We follow evidence-based guidelines from leading endocrine and longevity medicine societies to optimize testosterone, thyroid, and other hormonal pathways. We also offer advanced peptide therapy to support metabolism, sleep, cognition, immune health, and cellular repair.

What kind of access do I get as a member?

Our concierge members receive:

• 24/7 access via phone, text, or video
• Same day or next-day appointments
• Direct communication with Dr. Mullins and your clinical team
• Rapid access to diagnostics, prescriptions, and referrals

Do you take insurance?

We are an out-of-network, membership-based practice, which allows us to provide longer visits, deeper evaluations, and truly personalized care. Some services may be reimbursable through your insurance, HSA, or FSA—we can help guide that process.

What are payment options?

Marshall offers paid in full discount. Other payment plans are available on a case-by-case basis. Patients maintain a credit card on file that is encrypted for maximal security.

Does Marshall offer Couples or Family Discounts?

Yes, 90% of Marshall Members are couples. We encourage couples’ participation as multiple studies have shown improved outcomes when spouses and significant others are both engaged in longevity focused programs.

Does Marshall offer Group Discounts?

Yes, Marshall frequently develops models for groups. These are personalized to the group’s size and goals.

What is the Marshall young adult program?

Many of our Marshall Medical Members have young adult kids. Marshall has programs for High School and College students that is lifestyle-centric and designed for the unique needs of this age group.

Does Marshall offer have a Referral Program?

A very high percentage of new patients are referred to us by currently satisfied medical members. We love these referrals as these referrals tend to be like minded, health conscious, results oriented men and women. Members receive a cash credit to be used for any of Marshall Services as a token of our appreciation. These direct referrals allow us to keep our marketing budget to a minimum and use those extra dollars to create an even more robust white glove experience.

Can I be seen at any of the Marshall Offices?

Yes, You may find that one office is a better fit based on location, but we will gladly see you at any of our offices.

What are Marshall Office hours?

Tuesday – Friday

8 AM – 6 PM

We are closed in observance of all major holidays and occasionally must be closed for inclement weather.

Are there additional costs outside of my membership plan?

Marshall offers discounted services to all its medical members. Our a la carte services include IV therapy, peptide therapy, regenerative medicine procedures, gym memberships, personal training, nutraceuticals, and aesthetic procedures.

Does Marshall provide discounted services to First Responders and Teachers?

Marshall is proud to offer a markedly reduced membership price for all first responders – police, fire fighters, paramedics, ER nurses, military personnel, and teachers.

How do I cancel my membership?

Marshall has one of the highest retention rates in the industry. If a patient must cancel, we ask for written notice at least 30 days prior to the end of the contracted term. In cases of financial hardship, Marshall will work with patients on a case-by-case basis to assist and avoid the need for discontinuing care.

Do you offer virtual programs for patients outside of your area?

Yes. Our Marshall Connect Virtual Longevity Program is available nationwide, providing executive clients with 24/7 access, biomarker testing, and advanced therapeutics—all delivered with the same hospitality and precision care as our in-person programs.
