The Panel-Fill Playbook

The 20:1 panel math

Dr. Paul Thomas runs Plum Health in Detroit. He's been open about the arithmetic. For Plum Health, it takes roughly twenty unique visitors to the site to produce one new member.

That's the conversion rate the whole rest of this playbook lives on.

Read it both ways. Forward: every twenty real visitors yields one new enrollment. Backward: if you need five new members a month, you need a hundred relevant visitors a month. If you need ten, you need two hundred. If you need twenty, four hundred.

That's not a model for a Detroit clinic only. It's directionally what every DPC practice we've looked at runs at when the site is doing its job. Some practices run hotter, three or four percent. Some run colder, two percent. Five percent is the working assumption. (If your practice runs hotter than 5%, the ceiling on your panel growth is your visitor count. If you run colder, the site is leaking somewhere and the fix isn't more traffic.)

Now the question stops being "how do I get more patients" and starts being "what are my five sources of relevant visitors, and is each one running."

That's what the five levers are. Each one is a visitor source. The website is what those visitors land on. The panel fills when all of it compounds.

Lever 1, Word-of-mouth

Word-of-mouth is the lever every DPC owner names first. It's also the one most owners over-rely on and under-instrument.

What it actually is. A current member telling a friend, a coworker, or a family member that they should come see you. Sometimes in person. Sometimes in a Facebook comment. Sometimes by texting your website link.

Why it's powerful. A referred visitor converts higher than a cold one. They show up to the Meet & Greet already half-sold. They're easier to close, they stay longer, and they refer others.

Where it leaks. Three places.

First, the friend asks the member where to learn more, and the member sends them to your site. The site is the handoff point. If the site doesn't carry the conversation forward, the referral dies on the homepage. The audit data on what kills referrals at the site is the subject of the paired playbook.

Second, you don't have a way to make asking easy. Members would refer more if you gave them something to send. A short page that explains the model. A guide they can text. A patient-stories section they can link to. Members who'd happily refer a friend often don't, simply because they can't summarize DPC at brunch and they have nothing to forward.

Third, you don't track it. Referrals come in unbadged. You can't tell which members are driving the panel-fill, so you can't thank them, so the next referral doesn't happen. The strongest members for word-of-mouth are usually a small subset of the panel; you can't reinforce a habit you can't see.

What the site has to do for this lever. Be a credible handoff. The five-second test on the homepage has to pass for somebody who just got told go check this out. Provider photo, what you do, who it's for, what it costs, how to take the next step. We come back to this in Lever 5.

The owners we've talked to who have the strongest word-of-mouth engines do one more thing: they make the referral easy to text. A short page on the site that explains the model in three paragraphs. A guide patients can send a friend. The page becomes the thing that gets forwarded. The forwarded link does the explaining the member doesn't have time to do at brunch.

If your panel is over fifty members and word-of-mouth still feels random, the leak isn't your members. It's the page they're trying to hand off to.

Lever 2, Employer contracts

Until very recently, the playbook said employer contracts were lever four or five. A nice-to-have. The fast lane if you could find it.

That was the old map. The new map: Hint Health's 2026 Trends Report shows that roughly 60% of active DPC memberships in the US are now employer-funded.

Read that twice. Sixty percent. Not patient-paid. Employer-paid. Self-funded small businesses, mid-size employers, a few large ones, plus the PE-backed players (Premise plus Crossover merged to about $2B and 900 centers) building a $2B employer-primary-care business on top of exactly this lever.

Which means: if you're not pulling employer contracts, you're competing for 40% of a market the rest of the field is fighting for 100% of.

What this lever looks like operationally. A small or mid-size local employer signs a contract that pays a per-employee-per-month fee in exchange for primary-care access for its workforce. Twenty to two hundred employees, typically. The HR person makes the decision. The CFO signs. The benefits broker is often the gatekeeper.

The math on a single employer contract dwarfs a month of individual enrollments. A 60-employee company at $60 PEPM is $3,600/month in recurring revenue, plus the cash-pay services any of those 60 employees opt into. One contract is the equivalent of twelve months of individual word-of-mouth growth. It's also a steadier base; employer contracts don't churn the way individual memberships do.

Where it leaks. Your site has no page that speaks to that HR person. The whole site is written for the individual patient. The HR person clicks in, sees a membership page priced at $99/month for a family, and clicks away. There's nothing on the site that says "if you're an employer, here's how DPC works for your team, here's our employer pricing, here's how to start a conversation."

Worse: the benefits broker who'd happily mention you to her self-funded clients can't find a page to forward. She can't be the advocate for the practice if you haven't made the asset she'd use. The lever that moves twenty members at a time stalls at the broker's inbox.

What the site has to do. Have an employer-recruiting page. Not a paragraph. A page. With the math the HR person needs (per-employee-per-month cost, sample group sizes, what's included, what's not), the benefits-broker pitch, and a way to start the conversation. This is the single most under-built page across the 27 sites we audited.

What goes on the page, practically: a one-line statement of what the practice offers employers; a per-employee-per-month price band; an example for a 30-person company and a 100-person company; the included services (visits, labs, messaging, after-hours, optionally cash-pay services at member pricing); how the contract works (PEPM, annual, the cancellation terms); a short FAQ for benefits brokers; and a way to start a conversation that isn't the patient-membership form. The brokers are gatekeepers; the page has to treat them as a real audience.

Spruce Health publishes a free playbook on landing DPC employer contracts that's the closest thing to an operational reference in the field. Read it. Build the page against it. The lane is wide open because most DPC sites don't have a page at all.

Lever 3, Community presence

Community presence is the lever that converts to the long tail of referrals you don't see directly.

What it actually is. You at the chamber breakfast. You at the school sports physical drive. You sponsoring the kids' soccer team. You giving a talk at the library on what DPC is. You writing a once-a-month column in the local paper, if your town still has one. The civic surface of the practice.

Why it's powerful. It's slow but it compounds. Year one of community presence produces a few referrals. Year three produces a quarter of the panel. The longer you do it, the more your name and the model's name are linked locally.

Where it leaks. The chamber meeting is at 7:30 a.m. on a Wednesday. Twenty people are there. Three are interested. Two of them go home and search for your practice. Their search lands them on a homepage that doesn't show that you're the doctor they met at the chamber, doesn't have a location page for their specific town, and doesn't make the next step obvious. The community work converted them. The site lost them.

Multiply that across the year. Twelve chamber breakfasts, four civic talks, six school events, the two Rotary lunches you said yes to. Each one produces a small handful of curious-but-not-ready prospects who go home and search. If half land badly, the year's community work returns half what it could have.

What the site has to do. Three things.

A real About page with the doctor's photo, full credentials, the why-DPC story, and personality. Not a paragraph. A page. The patient who heard about you at the chamber wants to feel like they already know you a little before the Meet & Greet.

A dedicated page per town or area served, with the town's name in the page title and the URL. Most DPC sites have one location page. The ones we audited that had multiple town pages, like EBO MD's four Missouri location pages, ranked locally in a way the rest did not. If you serve three towns, you need three pages. Each one with the town's actual name and a few hundred words about why people in that specific town come to you. Local search rewards specificity.

A way for the chamber-met patient to book a Meet & Greet or send a question without picking up the phone. Online booking, a contact form, an email capture if they're not ready yet. If the next step is "call this number during business hours," half of them won't.

The community lever is patient work. A year of chamber breakfasts and school events feels invisible until somebody mentions, in month fourteen, that their neighbor's been talking about you for six months. That's the lever working. The site has to be the place where that six-month internal conversation finally lands on a page that closes it.

Lever 4, Physician referrals

Specialist relationships are the lever that's underused in DPC because it feels old-school. It isn't. It still works. And it works for a reason that's specifically DPC-shaped.

What it actually is. A cardiologist sends you a patient. A dermatologist's office calls because they liked working with you on a shared case. An OB you know from residency mentions you to a friend who's looking for a primary care doc. Physician-to-physician referral. The thing that filled FFS panels for decades.

Why it's powerful for DPC specifically. Patients with chronic conditions, complex med lists, or specialty needs are the patients who get the most out of DPC. They're the ones who feel the difference. A cardiologist who sends you her HFrEF patient and gets back a note that says "saw her, got her on the right titration, she has my cell" sends you the next one. That's a sticky, high-LTV member.

Where it leaks. Two places.

First, the specialist looks you up before they refer. They want to know they're sending their patient to somebody credible. Your About page is a paragraph. Your bio doesn't show your training, your boards, your hospital affiliations. Another physician reads that page and pauses. The referral doesn't happen. The cardiologist's office manager may even be the one doing the lookup, and an office manager who can't quickly verify your credentials defaults to the bigger name.

Second, the patient gets the referral, looks you up, and gets the same impression. The credibility stack on your homepage either passes the physician-vetted test or it doesn't. A patient told go see Dr. X, she's terrific is still going to vet you on the way in. Half the time they vet at a stoplight on their phone.

What the site has to do. Stack credibility plainly. Provider photo. Full credentials. Board certifications named (ABFM, ABLM, ABOM, ABIM, whichever apply). Hospital affiliations. Training pedigree. Then on top of that, the human signal. What you cook. Where you grew up. Why you left FFS. The specialist needs to see both: the credentialed doctor and the person they're sending their patient to.

The site is doing two jobs on the same page. The credential stack handles the specialist's professional check. The personal voice handles the patient's relationship check. Both readers are looking at the same words. Both have to come away ready to take the next step.

A small note on dated, named patient reviews: they belong on the same page. The trust stack lives or fails together. A homepage with thirty dated named reviews (Seacoast in our audit had close to that) does a job a generic "what patients say" testimonial block can't. The patient who's checking you out reads the reviews. The specialist who's vetting you reads the credentials. Both groups skim the page, but they skim different parts, and both halves have to be there.

Lever 5, The website

The website is the fifth lever. It's also the surface the other four bounce off of.

Every word-of-mouth referral, every chamber-met prospect, every employer's HR director, every specialist's curious-glance lookup, every Facebook post, every podcast mention, every Google search. Almost all of them route through your homepage. The doctor's work makes the visit happen. The site decides what happens next.

When the site does its job, the other four levers compound. The referred friend gets the right impression and books. The HR director finds the employer page. The chamber prospect finds the town page. The specialist sees the credentials. Every lever's work earns its return.

When the site doesn't do its job, every lever leaks at the same point. You can run great word-of-mouth and great community work and good specialist relationships and still fill the panel at one new patient a week, because every one of those efforts gets dropped at the homepage.

We've audited 27 real DPC sites in detail. The patterns are specific and they're repeatable. Five failure patterns show up across the sample, each one cutting a different lever's return. They're the subject of the paired product, The 5 Ways DPC Sites Cost a Practice Members.

The short version, in case you're not going to read the second product right now:

• The doctor's About page reads like a CV, not like a person.
• The membership pricing is hidden behind a "schedule a consult" gate.
• There's no employer-facing page at all.
• Cash-pay services (GLP-1, hormones, peptides, longevity) are framed as a separate "Store" or "Aesthetics Clinic," not as a relationship.
• There's nothing for the not-ready-yet visitor to do except leave.

Any one of those is enough to leak. Sites we audited at 11 out of 40 on the scorecard are hitting four of the five.

The site isn't an asset that sits separately from the panel-fill work. It's the surface the panel-fill work either compounds on or runs off of.

This is the framing that disarms the most common objection a DPC owner has to a website project: "I already do word-of-mouth, I don't need to spend on a site." Both halves are true. You do already do word-of-mouth. And you do need the site, because the word-of-mouth bounces off it. The site isn't the alternative to the lever. It's the surface the lever has to land on.

Where to start, the first 90 days

The temptation is to start with the lever you're most comfortable with. Don't. Start with the surface every other lever needs.

Days 1 to 30: The site is the foundation. Before the chamber breakfast, before the HR director, before the specialist looks you up: the site has to be ready to receive what those efforts produce. Provider bio with credentials and personality. Membership pricing published. A page for each town served. An employer-facing page, even a simple one. A way for a not-ready visitor to leave an email and hear from you later. If you skip this step and run the levers anyway, you'll be paying for traffic the site can't catch.

Days 31 to 60: Community and specialists, in parallel. The chamber, the school sports physicals, the talk at the library. The cardiology group's office manager, the OB you trained with, the dermatologist who's referred you a patient before. These take weeks to compound, so they start as soon as the site can hold them.

Days 61 to 90: Employers. With the employer-facing page live and the credibility stack built, the employer outreach goes out. Self-funded small businesses in your area (your benefits broker can name them). HR directors at twenty-to-two-hundred-employee shops. Spruce Health's employer-contract playbook is the operational reference. Aim to be the practice the local employers find when they start asking.

Word-of-mouth runs through all 90 days. It's the lever that needs the least planning and the most patience. Every member who walks out happy is a future referral. Give them something to send. Make the asking easy.

The sequence matters because if any lever runs ahead of the site's ability to receive, the work leaks. The site is the foundation. The levers are the wells.

What this isn't: a launch sequence. The first 90 days framing isn't a marketing campaign with a start date and a kickoff post. It's the operational order of how the panel-fill system gets built. You don't launch the site, then launch the chamber, then launch the employers. You build the site so the chamber and the employers and the specialists have somewhere to send their respective audiences. The website doesn't get a launch event. It gets a job.

The math, again

Back to the 20:1.

You need five new members a month. At a 5% conversion rate, that's 100 relevant visitors a month. Thirty-three a week. Around five a day.

Where do those five a day come from? The five levers.

Word-of-mouth: one or two a day if the panel is over fifty members and they have something to send.

Community: one a day from the chamber, the talks, the local content. It compounds; year one is less, year three is more.

Specialists: one a week from physician referrals, more once the relationships are seasoned.

Employers: not a daily lever. A few visitors a week from HR-side referrals once the page is live. The volume isn't visits; the volume is signed contracts, and one contract is ten to two hundred members at once.

Website (organic search, direct, social): one or two a day if the site is doing local SEO and the practice is putting one piece of content out a month.

That's the five a day. That's the panel filling at five new members a month. That's the path from 92 members at month twelve to a full panel by month thirty.

The math isn't a stretch. It's what happens when all five levers are running, when the site is doing its job, and when every visitor source has somewhere to land that doesn't drop them.

A practice running one lever well and four levers poorly tops out fast. A practice running three levers well still leaks where the other two don't show up. A practice running all five compounds. That's the difference between the panel that fills and the one that stays half-empty.

The work is the levers. The surface is the site. The number is 20:1. The panel fills.
