Most agencies hand you a login and an invoice. Fill The Lobby builds the patient-acquisition system, runs it, and owns the work after the click. The agency serves cash-pay and private-pay specialty practices across eight specialties: therapy and counselling, psychiatry, ketamine and Spravato, IOP and PHP programs, concierge and direct primary care, functional medicine, GLP-1 weight loss, and gastroenterology. Ads bring the patients. Six more services stop them leaking on the way to the calendar: booking pages, missed-call recovery, compliant patient reviews, follow-up, reactivation, and local SEO. Everything is measured on booked appointments — not clicks, impressions or leads. The difference: Fill The Lobby's founders own and run two healthcare platforms hosting 165+ clinicians. Every tactic the agency sells runs on those platforms first, with its own money. The only agency that is also the customer. Engagements start with the Proof Pilot: 30 days, one flat fee. Week one is an audit, not a pitch. Ad spend goes from the client's own accounts directly to the platforms. Copy is written to be board-safe, reviewed against APA, ACA, NASW and state board advertising rules.
