In a sleek, serene corner of Houston’s prestigious River Oaks District, Sydenham Clinic is quietly transforming the way high-achieving Houstonians approach their health, not with wait times and rushed visits, but with deep diagnostics, 24/7 access, and a doctor who doesn’t just treat symptoms, but rewrites medical expectations.
At the forefront is Dr. Adam Brittain, a board-certified internist with dual training in internal medicine and surgery. After years of delivering elite concierge care to some of the most influential figures in fashion and finance, Dr. Brittain has elevated his practice from excellent to extraordinary by joining Sydenham Clinic in 2023, where medicine meets data-driven precision and personalized longevity strategies. With Sydenham’s comprehensive, forward-thinking methodology, he’s not just managing health — he’s optimizing it.
“Beyond the ultra-specialized testing and the unrivaled level of exceptional concierge care, we focus on offering these things in a warm, welcoming, family environment. At Sydenham, we treat all of our patients as we would our own family. Our patients are family”, said Dr. Brittain.
The Concierge Difference: Time, Trust, Transformation
While traditional primary care is often reactive — treating illness after symptoms appear — concierge medicine is proactive. It’s not just about staying healthy; it’s about getting healthier.
At Sydenham Clinic, new patients undergo a comprehensive intake: full genetic panels, intracellular health testing, gut microbiome analysis, a liquid DNA cancer screen, advanced cardiovascular imaging, and more. The result is a custom-tailored health blueprint that focuses on optimization, prevention, and longevity.
And sometimes, those tools save lives.
“One of my patients had been recently cleared by his cardiologist and sent home after a negative stress test,” Dr. Brittain recalls. “He had no chest pain, no symptoms. But we ran a CT calcium score and a CLEERY scan — tests most primary care doctors never order — and found a 90% blockage in a major coronary artery. He had a life-saving stent placed the very next day.”
Mold, Mystery, and Medicine: A Personal Journey
While Sydenham patients range from Fortune 500 executives to fitness enthusiasts, many come with mysterious symptoms that traditional doctors can’t solve. One such case involved a long-time patient who had been mostly bedbound for four years, suffering from brain fog and extreme lethargy.
“I took her case because I saw myself in her,” says Dr. Brittain.
During his medical residency, Dr. Brittain began experiencing numbness, fatigue, and neurological symptoms. Misdiagnosed with multiple sclerosis, he eventually discovered the real culprit: toxic mold exposure. Through self-research, deep diagnostic testing, and eventually developing his own treatment protocol, he healed himself — and now helps others do the same.
The patient? “Within three weeks, she was significantly better. Within a few months, she was back to living a full life,” he says.
Redefining Longevity
Dr. Brittain doesn’t just treat illness. He treats aging itself. With a disciplined regimen that includes a strict ketogenic diet, intense exercise, red light therapy, and both sauna and cold plunge therapy four times a week, he’s his own best example.
“Longevity isn’t about magic supplements or fancy stem cells,” he says. “It’s about deliberate, daily choices. I call them ‘good stresses’: cold, heat, fasting, and movement. They build resilience. And resilience is the key to living longer — and better.”
The Iceberg Analogy: Why Traditional Care Misses the Mark
To explain his philosophy, Dr. Brittain often uses the iceberg analogy.
“Inflammation is a normal and necessary process. We need it to survive. The ice, beneath the surface that we can’t see, is our normal, baseline level of inflammation. Once the RATE of inflammation increases, that’s when the ice becomes visible above the surface of the water. These are your symptoms, this is your disease process. Decreasing the rate of inflammation is one of the two key processes to achieve increased longevity”. he explains.
It’s not about waiting for things to go wrong. It’s about creating a system where they rarely do by finding the root cause with precision medicine, along with lifestyle.
A Clinic Unlike Any Other
Being a patient at Sydenham Clinic means 24/7 access to your doctor. Texts. Calls. Immediate specialist referrals. All-year deep diagnostics. Personalized health optimization plans.
And whether a patient arrives with a pressing illness or just a desire to optimize performance, they leave with more than just lab results.
“They leave with a new baseline,” says Dr. Brittain. “Most people don’t know how good they could feel — until they finally do.”
Final Word: The Body Wants to Heal
For anyone feeling unheard, misdiagnosed, or simply off, Dr. Brittain offers a powerful reminder:
“The body wants to live. It wants to heal. You just have to give it the right environment.”
