Take your health to the next level.
Two Mayo Clinic–trained physicians. Just 100–150 patients each. The unhurried, deeply personal care of traditional medicine — joined with functional, integrative and precision medicine, on your terms.
Most concierge doctors carry 400–600 patients. We deliberately take a fraction of that — so we can truly know you, your family, and your health.
Trained & partnered with the leaders in medicine
Medicine the way it was meant to feel.
If you've ever felt rushed through a 12-minute visit, waited weeks for an appointment, or bounced between specialists without a plan — you've felt what modern medicine has become. We built Next Level to be the opposite.
We spend real time getting to know you as a person, and design your care around your priorities and philosophy — the best of traditional Western medicine and leading-edge integrative, functional and precision medicine.
- Direct, unhurried access to your physician
- Care coordinated across every specialist
- Prevention & precision, not just sick-visits
- Whole-person care — mind, body & spirit
Three cornerstones of Next Level care
We focus on your health, delivered in the ways most suited to your priorities and your style.
Personalized Precision Medicine
We use advanced biomarkers and imaging to see your whole picture. About 70% of our members add genomic testing, letting us target the pathways that shape your long-term health.
The Best of Both
Traditional Western medicine and integrative, functional approaches — together. Nutrition and lifestyle as the foundation; pharmaceuticals and natural medicine layered in by your choice.
Leading-Edge Updates
Medicine moves fast. We translate the latest developments into clear, personalized guidance — and bring it to you, so your care is always current.

Patients who followed them across the country
Many members have trusted these doctors for 15, 20, even 25 years — through migraines, cancer, and everything in between.
The treatments for my chronic migraines combined supplements, mild prescriptions and hormonal balancing. Within six months I went from 4+ migraines a month to zero over four months. That's just one example.
— Sarah D. · Yelp review, 2021I contracted Covid, was diagnosed late on a Saturday, sent one text, had one call within minutes, got meds at my pharmacy an hour later. Received calls and check-in texts the whole way through.
— Mark O. · Yelp review, 2023Under the concierge model, he has all the time you need to make sure all of your concerns are addressed thoroughly and proactively. Even though I have moved out of state, I have retained him as my doctor.

How Membership Works
Concierge medicine, explained
We do not accept private insurance; the practice is membership-based. We accept Medicare for Medicare-covered services, and your annual membership covers the integrative, functional and complementary care Medicare doesn't. You keep your own insurance for hospitalizations, surgery, ER and specialty care.
Just 100–150 patients per doctor — compared with 400–600 at most concierge practices and 2,000–2,500 in traditional medicine. That's the whole point: we have time to truly know you.
Yes. We provide phone follow-up — and office care when appropriate — outside traditional hours. Members reach us directly through the secure Spruce app for both text and phone contact with their doctors.
We care for snowbirds at no additional charge beyond membership and usual charges, coordinating your care in other locations and while you travel where feasible. We do ask to see you once a year in Arizona.
