Something feels off. Not enough to go to the ER, not nothing either, the kind of symptom that sits in the back of your mind for a few days while you tell yourself it will probably pass. You call your doctor's office. You're told the next available appointment is in three weeks, and if it gets worse before then, go to urgent care. So you wait, and you worry, and by the time you're finally seen, three weeks of low-grade anxiety have passed for something that might have taken fifteen minutes to rule out on day one.
This isn't a rare story. It's the default experience of primary care in this country right now, and it's gotten worse, not better. A 2025 survey by AMN Healthcare found it now takes an average of 31 days to get a physician appointment across 15 major metropolitan areas, up 19% since 2022 and 48% since 2004. In Boston, new patient waits average 65 to 69 days. A CEO of a healthcare benefits company described it taking six to nine months just to get a primary care appointment in New York City. And per PartnerMD's 2026 State of Primary Care Report, 62% of people either wait at least a week to see their doctor or don't have a primary care physician at all, while 80% say they worry about important health issues slipping through the cracks because of it.
Why this happens even to people who can afford anything
Access isn't a money problem for most of the families I work with. It's a structural one. A traditional primary care panel holds two thousand, three thousand, sometimes more patients per physician. There is no version of that math where same-day access is possible for everyone who needs it. The doctor isn't failing you. The model was never built to let her succeed.
This is exactly why I keep my membership deliberately small. When a physician isn't managing thousands of patients, same-day and next-day access stops being a marketing promise and becomes something I can actually deliver, because there's room in the schedule to deliver it.
What access actually looks like here
Members get same-day and next-day appointments when something comes up, not a triage call center deciding whether your concern is worth seeing you for. Beyond scheduled visits, you have 24/7 direct access to me, meaning an actual line to me, not an answering service that takes a message and promises a callback sometime tomorrow. For urgent concerns before 7pm, you call and reach me directly. After 7pm, that line is reserved for true medical emergencies, and any non-urgent message gets addressed by 9am the following morning, so nothing sits unanswered overnight. Non-urgent questions can also go through secure messaging or a quick telehealth visit, so a concern doesn't have to wait for the next in-person slot just to get a real answer.
None of this means I can be everywhere at once or that I'm claiming to replace a hospital's emergency department. What it means is that when you have a question, a concern, or something that needs a same-day look, the answer isn't a three-week wait and a suggestion to try urgent care instead.
What this is actually buying
The families I work with aren't paying for access because they're impatient. They're paying for it because they've learned what happens when access isn't there, the missed early sign, the ER visit for something that should have been a phone call, the three weeks of worry that could have been a same-day conversation. One patient described it simply: "Always available and takes care of what I need." That was said years before this practice even existed, which tells me it was never really about the practice. It was about a way of practicing medicine that puts a doctor within reach when it actually matters, not just when the schedule happens to have room.
For frequent travelers, for parents managing a child's fever at 10pm, for anyone quietly responsible for an aging parent's care from a distance, this isn't a convenience feature. It's the difference between handling something calmly in the moment and spending a night wondering whether you should have gone to the ER.
Access without the tradeoffs you'd expect
I want to be honest about what this isn't. Being reachable doesn't mean I skip the parts of medicine that require real time, the unhurried exam, the full history, the conversation that actually gets to what's going on. Access and depth aren't in competition here. The same small membership that makes same-day appointments possible is what makes 90 to 120 minute first visits possible too. One doesn't come at the cost of the other. They come from the same decision, to keep this practice small enough that both are real.
If you've spent years telling yourself a symptom will probably pass because getting seen felt like more trouble than it was worth, or if you've sat with a sick child at night wondering whether it's worth a trip to urgent care, this is what I built Mercer Medical Greenwich to change. You can schedule an info call with Nadia, our Membership Director, to talk through what your own access to care would actually look like, day to day and at 2am, before anything is decided.
