Forget sitting in the reception area for 30 minutes — across New York, Miami, SF and LA, preeminent doctors at concierge clinics are the ones waiting on their patients.
Practices differ in purposes and perks, but usually follow a similar mold. In exchange for membership dues, some of which run as high as $250,000 per year, they offer direct access to doctors and their rolodexes of specialists, hyper-personalized care and levels of attention increasingly rare in traditional medicine.
The model is booming.
The market for concierge and personalized medical care is expected to grow by more than 50%, to top $11 billion a year, by 2032, Precedence Research reports.
So, what’s the best health money can buy? And what’s behind the concierge medicine craze? NYNext spoke with doctors at five of the country’s most popular clinics to find out.
“When you know your patients well enough, [medicine] is no longer transactional,” Dr. Jordan Shlain, founder of Private Medical, told NYNext. “There’s no motive other than good health.”
Shlain founded Private Medical, a physician-owned concierge practice, in Silicon Valley in 2002.
Born and raised in San Francisco, and formerly a resident of internal medicine at UC San Francisco, his firm was among the first in the country to reject insurance-company driven models and outside investors in favor of long-term, relationship-based care.
“We don’t make compromises for profit,” he said.
His practice now has offices across the country, but despite the expansion, Shlain insists relationships with his original patients haven’t faltered.
“I was taking care of all these young tech people that now run the universe,” Shlain said. “We’re [still] their doctor … everybody wants to show us [what they’re building].”
Shlain contrasts Private Medical’s approach with what he calls “performative medicine” and the increasingly theatrical longevity space. He offers no “peptide freak shows.” Nor testing for testing’s sake. At Davos 2026, he even gave a talk on the hype and myth around longevity.
“We do the right thing, for the right reason, at the right time,” Shlain said. “It’s really simple.”
Key benefit: Private Medical was an early testing ground for Galleri, a blood test that detects cancer signals through DNA fragments. In 2021, the test was used to flag colon cancer in a 38-year-old patient of Shlain’s who felt otherwise healthy. A colonoscopy confirmed a two-centimeter tumor, and surgery and treatment followed. Today, the patient is cancer-free and a father of two.
Locations: New York City, Miami, San Francisco, Silicon Valley, Beverly Hills and Santa Monica.
Cost: $45,000 for adults and $28,000 for kids, billed yearly. Family bundle options are available upon request.
While the majority of concierge clinics focus on primary and preventive care, Sollis Health, founded in 2016, was built for when things go wrong.
“We’re like your own private emergency room,” Dr. Scott Braunstein, Sollis’ chief medical officer, told NYNext.
Sollis clinics operate 24/7 and can treat roughly 95% of the cases a traditional emergency room sees, including: fractures, lacerations, infections, chest pain, dehydration, kidney stones and allergic reactions.
Clinics are staffed with all the tools doctors can access in traditional emergency rooms — labs, IV medications, ultrasound machines, EKG tests and procedure rooms.
“COVID changed how cognizant people are of risks to their health,” Braunstein said. “People really didn’t want to be in the same waiting room with anyone who was coughing and might be ill.”
The concierge also acts as a sort of care navigator, coordinating rapid specialist referrals when needed. Braunstein references one recent case in which an elderly patient with blood in his urine received labs, imaging, treatment and a urology referral — all in one day.
“The emergency care system in this country is overwhelmed and overtaxed,” he said. “Concierge medicine offers time and trust. That leads to more accurate diagnoses.”
Key benefits: Clinics are staffed exclusively by board-certified emergency physicians and equipped with hospital-grade imaging (X-ray, CT and MRI), labs and ICU-level monitoring. There are no residents, no hand-offs, no crowded waiting rooms. For particularly complex cases, plastic surgeons are called in on-demand to repair lacerations.
Cost: Membership begins at $4,000, billed yearly.
Locations: Fifteen centers span New York City, the Hamptons, South Florida and California.
New York’s preeminent longevity clinic, Extension Health caters to celebrities, professional athletes and even royal families; including, reportedly, actor and director Justin Baldoni, Hall-of-Fame quarterback Troy Aikman and brother of Elon, Kimbal Musk.
“We’re at the frontier,” Dr. Jonathann Kuo, Extension Health’s founder, told NYNext. “We’ve built an ecosystem on the newest advances in diagnostics and therapeutics.”
Members begin with a robust slate of lab-work, then receive treatments like vitamin IV and peptide therapies (which are also available à la carte).
The pinnacle of the clinic’s offerings is the quarter-million dollar Superhuman Membership. These members receive all the aforementioned longevity therapies, and also work directly with Kuo to develop a customized wellness plan based on hundreds of biomarkers tracked via wearable technologies.
“We become the co-CEO of your health,” Kuo said. “And the outcomes speak for themselves.”
Key benefits: Extension offers Extracorporeal Blood Oxygenation and Ozonation (EBOO) ozone therapy, which filters toxins and pathogens out of blood, adds oxygen and then returns it to the body to boost autoimmune and vascular health.
Transcranial focused ultrasounds, which beam directly into the hypothalamus to re-regulate hormone secretion and reverse the processes of aging.
And neuro-resets, injections into two nerves at the base of the neck to kickstart the autonomic nervous system, boost memory and relieve stress.
Location(s): Extensions’ sole outpost, for now, is in West Village. A new longevity flagship is currently under construction downtown and the clinic is exploring opportunities in Miami and Los Angeles.
Cost: Membership ranges from $50,000 for “The Catalyst” to $250,000 for the “The Superhuman,” billed yearly.
Tracing its roots back to the mid-90s, MD² is one of the nation’s leading and largest concierge primary care practices.
The company has nearly three dozen clinics, each of which is independently owned by two doctors and cares for no more than 100 families. Two-thirds of MD²’s clinics are fully occupied.
With a direct line to the physician via personal cell numbers, patients can call or text at any time to request same-day appointments and home-visits when appropriate. If the patient is seeing a specialist, their physician might come to serve as an advisor in those meetings, too.
“When a patient comes in for their annual physical, I’ll be with them for two to three hours,” Dr. Jonathan Waitman, a physician at MD²’s East 57th Street practice, told NYNext. With his previous employer, Cornell Weill, Waitman says he was seeing new “patients every 15 to 30 minutes.”
MD²’s offices have no waiting rooms (but do offer breakfast and beverages). When patients arrive at their scheduled time, they are immediately whisked in to see their doctor.
Each office is equipped with standard radiology, EKG and ultrasound equipment, as well as a registered nurse, medical assistant and radiation technologist.
Patients will receive the most personalized care at their home clinics, but for those who frequently travel and in case of emergencies, MD²’s offices remain open to out-of-towners.
If a medical emergency occurs abroad, patients also have access to medical air transport via MD²’s partnership with MedJet.
“We’re trying to take the best care of patients, without the constraints of time,” Waitman said. “It’s the ideal way to practice medicine.”
Key benefit: Time: “Patients have as much time as they need to explain to me what’s going on in their lives, both personally and medically,” Waitman said.
“By virtue of us keeping our patient volume very low, we can guarantee patients access to us — not to a nurse practitioner.”
Location(s): 35 locations span 15 states, including New York, with locations on East 57th Street, Fifth Avenue, Gramercy Park, Madison Avenue and Park Avenue.
Cost: From $24,000 for an individual to $60,000 for a family with two adult children, billed yearly.
This story is part of NYNext, an indispensable insider insight into the innovations, moonshots and political chess moves that matter most to NYC’s power players (and those who aspire to be).
Dr. Florence Comite is an endocrinologist by trade, one of the world’s preeminent experts on longevity and founder of the Comite Center for Precision Medicine & Healthy Longevity, which moved from Connecticut to New York in 2005.
The seed for what would become the Comite Center for Precision Medicine & Healthy Longevity, however, was planted some 13 years earlier.
In 1992, then an associate professor at Yale’s medical school, Comite had grown frustrated with the industry’s inability to think proactively.
“We were waiting for disease to strike, thinking [only] reactively,” Comite told NYNext. “But through the data — regular lab tests in the 90s, and now wearable tech — I could see what path patients were heading down and intervene [before they got sick].”
Comite bills her practice as a new style of family medicine and primary care. “We take care of the whole human being,” she said.
That work begins with a sundry of lab tests — including measuring VO2 max, the maximum rate of oxygen consumption attainable during physical exertion. — bloodwork and genetic testing. Comite also prescribes continuous glucose monitoring to nearly all her patients.
Doctors use these results to identify inherited risk patterns and early signs of diseases, ranging from Alzheimers, to hypertension, to cancer.
Next, intervention plans are developed, often including some combination of hormonal or metabolic treatments, supplements, medications or exercise prescriptions, nutritional management programs and, in some cases, advanced therapies like therapeutic plasma exchange, which filters toxins from blood, similarly to EBOO ozone therapy.
“Connecting the dots, we can reverse disease,” Comite claims.
Key benefit: Genetic and epigenetic analysis are fundamental to the initial screening and later tracking Comite’s patients undergo.
“Learning about how your body actually engages with not just food, but sleep, the environment, stress … all [these factors] have effects,” Comite said.
“A lot of people think you can change your lifestyle and you won’t get sick, but that’s not always true. Putting biomarkers together with your genetics — that’s what gives you the strongest impact.”
Location(s): Central Park South, Miami Beach and Palo Alto.
