Patient Acquisition & Retention Agency

A patient acquisition and retention agency runs the whole path between a practice and its patients: the search, ads and reviews that bring new patients in, and the booking, answered calls, follow-up and reactivation that stop them slipping away before or after the first visit. It reports on booked appointments, not clicks. Fill The Lobby is a patient acquisition and retention agency for cash-pay and private-pay practices in the US.

Acquisition and retention are one job.

The patient you win this month is the one you need to see again next month, and the skills barely change: answer fast, make the next step easy, and follow up until there is an outcome, whether the person is booking a first visit or a fifth.

Split that across vendors and every handover becomes a leak. An ad agency gets paid whether or not the phone is answered; a reminder tool gets paid whether or not anyone rebooks. One team accountable for the whole path is the point of the category.

The seven leaks.

Seven places a practice loses patients between a first search and a returning visit. We call them leaks because each one is money already spent: attention, a click, a call, a patient who already trusted you. Every audit we run starts here.

1. Not being found

The patient searched, or asked an assistant, and the practice wasn't in the answer. Fixed with a Google Business Profile someone actually maintains and pages that state what you treat and what you charge in plain text. How we run healthcare SEO and AI visibility.

2. Paying for the wrong clicks

Ads that reach people who were never going to book: insurance shoppers for a cash-pay practice, the wrong city, the wrong need. Counted on booked appointments rather than clicks, the waste stops hiding. How we run paid ads.

3. A page that can't take a booking

The ad works and the page doesn't: no fee, no availability, no way to book at 9pm on a phone. How we build booking pages.

4. The call nobody answers

A new patient calls during a session and reaches voicemail, and the next practice on the list is one tap away. How we answer calls.

5. Losing the comparison

Before they book, people compare, and thin or stale reviews lose that comparison quietly. Reviews get requested the same way every time, inside the rules each clinician's board sets. How we handle reviews.

6. The inquiry nobody follows up

A form arrives, someone replies once, it's marked contacted and never booked. Every inquiry should be followed to a real outcome: booked, or closed for a reason. How we follow up.

7. The patient who drifts away

The retention leak: no next visit booked at checkout, a reminder nobody could act on, a lapsed patient nobody asked back. Brought back under the practice's own relationship, with a genuine reason. How we run reactivation.

Agency, software or an in-house hire?

Illustrated scenario. Characters are fictional.

Five common ways practices buy patient acquisition, and where each one tends to break.

Option	What you buy	Measured on	Where it tends to break
Marketing agency	Ads, SEO, content and a monthly report	Clicks, impressions, leads	After the click. Calls, follow-up and rebooking belong to nobody.
Booking platform listing	A profile on a booking platform, listed beside other practices	Bookings through the listing	Your name. Patients compare you with the listings beside yours and remember the platform, not you. Keep it as one way in, not the only one.
Patient engagement software	A platform for reminders, messages and reviews	Messages sent, features used	Set up once, then left to busy staff. Nobody owns whether it books anyone.
In-house marketer	One person across every channel	Whatever they choose to report	Breadth. Ads, search, phones and follow-up are four jobs, and the knowledge leaves with the person.
Patient acquisition & retention agency	The path from search to returning patient, run as one system	Booked appointments	Access. It only works with sight of how the practice books, which is why week one is an audit.

How to choose a patient acquisition agency.

What do you report on?

Booked appointments, by channel, with the cost of each. Clicks and leads are inputs. If the report stops there, nobody is accountable for the part that fills the schedule.

Whose ad account is it?

Yours. Campaigns, history and audiences should stay with the practice if the agency doesn't. Ask whether ad spend is marked up.

Who answers the phone?

Ask what happens at 12:40 on a Tuesday when a new patient calls during a session, and at 9pm when a form arrives. If the answer is “that's your front desk”, you've found the gap.

Will you sign a business associate agreement first?

Follow-up and reactivation touch real patient relationships, so the agreement comes before any patient data moves. No protected health information should reach an ad platform, and patient lists shouldn't be used for targeting.

What won't you put in an ad?

Your board's advertising rules decide what's allowed, and patient testimonials and promised outcomes are the usual problems. A good agency tells you what it won't write before you ask.

How do we start, and what does it cost?

Look for a short, fixed-fee start that opens with an audit rather than a promise, with ad spend paid by you directly to Google and Meta.

Do you run this on your own business?

Anyone can draw a funnel. Ask whether they pay for the same tactics with their own money.

Why Fill The Lobby calls itself one.

Because we're also a customer. Our founders own and run two healthcare platforms, Shifa Therapy and Counsel Clinic, which host 200+ clinicians with patients in 20+ countries. Every tactic on this page runs there first, with our own money, before we run it for anyone else.

Engagements start with the Proof Pilot: 30 days, one flat fee of $2,500, and week one is an audit, not a pitch. Ad spend sits on top and goes from your accounts straight to Google and Meta.

Built for cash-pay specialties.

The same seven leaks, tuned to how patients in each specialty decide and to the advertising rules each one works under.

Questions

Patient acquisition agencies: what owners ask.

It runs the channels that bring new patients to a practice (usually search, paid ads, reviews and directories) and the steps between an inquiry and a first appointment: the booking page, the phone and follow-up. A patient acquisition and retention agency also runs what happens after the first visit, such as rebooking, reminders and reactivation.

Acquisition wins a new patient's first appointment. Retention keeps an existing patient coming back for the care they need. The two share most of the same work (answering fast, making booking easy, following up until there is an outcome), which is why we run them as one job.

Mostly in where the job ends. Many healthcare marketing agencies deliver traffic and report on clicks, impressions or leads. A patient acquisition agency is measured on booked appointments, so the phone, the booking page and follow-up are its problem too. Our guide to healthcare marketing agencies sorts the main firms by who they serve, and our guide to alternatives covers the options for a small practice.

It varies by agency and scope. Ours is public: the 30-day Proof Pilot is one flat fee of $2,500, with ad spend on top, paid from your own accounts straight to Google and Meta. Plans after the pilot are scoped to the practice.

It depends on the channel. Paid search starts sending traffic as soon as campaigns are approved, so the early weeks are about whether that traffic books. Search rankings and reviews build over months. In our pilot, you see where the practice is leaking in week one and, by week four, what was booked, where each booking came from and what each cost.

Some of the work does, because follow-up and reactivation touch real patient relationships. That is why a business associate agreement is signed before any patient data moves. No protected health information goes to ad platforms, and patient lists are not used for ad targeting.
