Raising The Bar In Concierge Medicine
What is Concierge Medicine?
Concierge medicine aims to provide a higher level of personalized care, often appealing to those seeking more direct
and consistent communication with their healthcare provider.
Key features include:
Extended Access: Patients usually have direct access to their doctors through phone, email, or text, often including after-hours.
Longer Appointments: Appointments tend to be longer, allowing for more in-depth consultations
Preventative Care: Emphasis on preventative care and wellness.
Limited Patient Load: Physicians typically limit the number of patients they see, enabling more time and attention for each patient.
Enhanced Services: May include comprehensive annual physicals, same-day or next-day appointments, and coordination of specialist referrals.

Find Your Why
“I found my purpose. I understand how the quest for arbitrary finish lines comes at a great cost. I experienced it first-hand. What started as a quest to find happiness, ended in the understanding that happiness can be fleeting, but purpose is not. Purpose drives me through life’s peaks and valleys. It adds clarity to difficult decisions about my career, my relationships, my life. I see my vision just as clearly as you see your hands. It acts as a beacon for me during times of uncertainty.
My vision is so clear, my purpose so de.ned, my “why” so ingrained that I wake daily with a dogged persistence to push forward. I have had plenty of failures, obstacles, and roadblocks. I have questioned my reasoning countless times. I have even considered throwing in the towel.However, I know that these same issues are being experienced by the very same people I wish to help – Executive Men and Women everywhere. I am compelled to keep going. In the end, I am motivated by pleasurable outcomes rather than pleasurable methods. I want to have an impact on patients that are struggling. Success is not an accident; it is a planned event.”

Time with your doctor matters
"I started Marshall Lifestyle Medicine to promote a new way of thinking about healthcare. Lifestyle Medicine involves the use of evidence-based therapeutic approaches such as the role of diet, physical activity, sleep, stress management, interpersonal relationships and other lifestyle behaviors that affect, alter, prevent, and potentially reverse age-related chronic disease. I am taking an expanded approach – promoting the role of Hormones, Peptides, Lifestyle Medications, Aesthetic Products and Services, and Regenerative Medicine Treatments to better promote living life optimally. My vision for the future of healthcare is one that is patient-first, efficient, preventative, life enhancing and unbound by the old rules pertaining to health management."

The Marshall Difference-
Raising the Bar
in Concierge Medicine
At Marshall Lifestyle Medicine, we keep our patient-doctor ratio small, so we can provide you, your family, or your organization with better access to care and the personal attention needed to thrive. Find out how our concierge medicine practice can improve your health care experience. We take an independent
approach away from insurance, pharmaceutical heavy or hospital driven care and focus solely on YOU.
Beyond just testing your bloodwork and checking your vitals, Dr. John Mullins and his expert staff are committed to helping you improve your health, wellness and vitality.
Yesterday's approach to healthcare isn't working. It is Broken. Passively waiting for illness to develop. Reacting with countless
tests, referrals, and medications all while neglecting the underlying causes of the problem. We invite you to try something new.
A health plan that is innovative and patient first.

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.

Can I keep my regular doctor or specialist?

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.

Does Marshall offer have a Referral Program?

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.
