Every patient should have a physician whose only job is to make sure their medical care actually works.
Most patients don’t. Carte is the company we built to close that gap.
Modern medicine has found extraordinary answers, but no system for patients to reliably access them.
The fifteen-minute appointment, the standardized algorithm, the structured electronic medical record template. All of these exist for the eighty percent of medical cases that fit the textbook. For routine cases whose treatment is straightforward, the system does what it was designed to do: maximize efficiency. The rest of the time, those same constraints become the problem.
The remaining twenty percent of cases take eighty percent of cognitive effort to solve. Their course and best path forward is not fully known at the outset. They require revisiting assumptions, looking at the problem across specialties, and some creativity. They call for the maker’s schedule when modern medicine runs on the manager’s.
The twenty percent of cases are not accounted for at doctor’s offices, hospitals, or by insurance companies. The twenty percent don’t get more time; they just get dismissed, shoehorned into standard care, or passed off as someone else’s problem. At a time when the textbook answers are easier to summon than ever, it’s the twenty percent that we want the best physicians to get the time to throw their energy into.
All of us eventually become a twenty-percent case. In those scenarios, we need a structure for doctors to give us the attention we deserve. That’s why Carte exists.
I started Carte because the pattern was too consistent to keep treating as exceptional. The errors weren’t exceptions. The system that produced them was the rule.Gina Siddiqui, MD · Founder
“Carte” means map. The Latin root of “hospital” is hospes — guest, visitor. For most of the last century, medical care made patients guests: passive, subordinate, recipients.
Carte is named for the conviction that medical care in this century should not make patients guests. It should give them what maps give: data, truth, and choice.
Lead physicians and an expert network built one at a time.
Lead physicians own each engagement end to end — they hold the full picture and are personally responsible for the plan actually happening. Consulting physicians are specialists we bring into individual cases to think alongside us. Both work for Carte’s clients, never for any other interest.
Gina Siddiqui, MD
Founder · Managing Physician
Dr. Siddiqui is the architect of Carte’s methodology. She trained at the University of Pennsylvania School of Medicine and completed her residency at Yale, then served as founding Chief Clinical Officer for an AI care-enablement platform covering 100 million lives. Before Carte, she designed care programs for the most complex patients in the NYC Health + Hospitals system — the work that produced the n-of-1 diagnostic approach Carte’s clinical practice is built around.
Dr. Siddiqui is Adjunct Faculty at the University of Virginia and at George Washington University, and sits on the Scientific Advisory Board for the Alliance for Longevity Initiatives. Her writing on the structural gaps in American medicine appears at The Physician Advisor.
Ashley Alwood, MD
Physician Lead · Clinical Investigation
Dr. Alwood leads Carte’s investigations on complex cases. Board-certified in emergency medicine, she trained at the University of Washington and at the University of Chicago, where she served as a Flight Physician — a role with strict selection criteria for clinical precision under pressure. She was subsequently recruited to lead the emergency systems at Cleveland Clinic Abu Dhabi and at The View Hospital, a Cedars-Sinai affiliate.
Dr. Alwood was raised in London and trained inside the American academic system. At Carte, her work focuses on multi-factor cases where multiple specialists have arrived at incompatible answers and the integrating question has not yet been asked.
Consulting specialists
By deliberate selection
Carte works with a network of approximately eighty consulting specialists spanning the major medical and surgical specialties. Each one was selected individually, almost always after working with them on prior cases — a process closer to deliberate hiring than to assembling a network. They are contracted as independent consultants and paid by Carte for their time, with no relationship to the client’s treating physicians and no financial interest in any particular recommendation.
We don’t publish the full roster. Individual consultants are sometimes named publicly — through our annual Specialist of the Year recognition, or in occasional profiles.
Five principles that distinguish how Carte practices medicine.
Independence.
We work only for the patient. Carte does not take referral fees, does not accept revenue from pharmaceutical companies or facilities. The only economic relationship we have is the one with you.
Primary data over reports.
Most diagnostic errors live in the gap between the original data and the reports about it — and one of the most important kinds of original data is the patient’s own account. We re-examine images against the originals, slides against the originals, lab trends against the originals. We also re-listen to the patient, with particular attention to the symptoms and details that didn’t make it into the chart. The decisions we are reviewing are usually too consequential to delegate to summaries.
Integration over specialty answers.
The hardest question in modern medicine is not “what is the right answer to this specialty’s question?” It is “what is the right answer when every specialty’s question is reconciled at once?” That integrating question is the one Carte exists to answer.
Execution over recommendations.
A correct plan that doesn’t get implemented is functionally equivalent to no plan at all. We treat the work of making sure the right appointments, tests, and follow-ups actually happen as half of the engagement, not as a postscript.
Restraint over optimization.
Carte does not sell more medicine. We do not sell longevity protocols, supplement stacks, or branded panels. We help the patient identify the right care, in the right order, applied with the right intensity — and the right intensity is often less than the patient was about to consent to, not more.
