Most physical therapy volume still starts as a physician or surgeon referral, and the space between "your doctor says start PT" and a booked evaluation is where patients disappear.

The agent catches them at the moment they act on it. It recognizes a referred patient, collects the referring physician, the condition category, the insurance, and the preferred location, then books the evaluation into your connected calendar or hands the request to that clinic with everything already gathered. Every conversation writes a structured, source-attributed record into Salesforce or HubSpot.

More referrals turn into first visits, and your business development team can show a surgeon's office what happened to the patients they sent.

Demand in physical therapy does not keep clinic hours. The weekend sports injury and the direct-access patient choosing between three clinics on their phone at 9pm both meet the same thing: a static location finder and a phone number that rings out.

The agent has the conversation your front office would have: what happened, their insurance, their location, their availability. It points them at the clinic that offers the service they need, whether that is hand therapy, vestibular, sports rehab, or post-surgical care, on web, WhatsApp, SMS, and email at any hour.

New patient visits your group used to lose overnight, captured on a surface you own.

A patient you converted is only worth the visits they actually complete. In the largest US study of musculoskeletal care attendance, covering roughly 445,000 patients, 73% missed at least one appointment, with a mean no-show rate of 17%. Each missed visit is revenue you already earned and did not collect.

When your systems pass the signal through, by API or webhook, event-triggered campaigns reach patients who miss a visit or go quiet mid-plan, on SMS or WhatsApp. The agent answers what is actually stopping them and puts the next visit back on the calendar. Clinical questions go to their therapist.

More completed visits per patient won, which is more revenue per patient won.

If your group runs employer services, two very different audiences hit the same website. Adjusters, case managers, employer contacts, and attorneys' offices arrive alongside your consumer patients, outside business hours, and go to whoever responds first.

The agent tells these apart from a new consumer patient and handles them in their own lane. These conversations touch claims, employers, and counsel, so it collects only what your business development team needs to respond and does not speculate about coverage, claim status, or liability. It routes the case to a person quickly with everything already gathered.

Your employer and workers' comp pipeline stops depending on who was at a desk when the case came in.

The first thing anyone senior does with a new agent is try to break it. In physical therapy the expensive failure is quieter: a wrong "yes, we take your plan" is a billing dispute with a patient you just won.

The agent answers from your own approved content and nothing else: per-location payer lists, referral and direct-access policies, hours and service lines by clinic. Outside that content it says so and hands off rather than inventing an answer, and it stays operational: no injury assessment, no treatment advice. Coverage and referral-requirement answers run as deterministic flows, identical on every channel.

Your compliance lead can read what the agent may say before a patient sees it.

For a PT group the conversion event is an evaluation on a real calendar. Every step between a form fill and that booking is a place the patient leaves: a callback request, an external booking link.

The agent qualifies in the conversation, then books in the conversation. The patient sees live availability computed against your hosts' Google Calendar or Outlook Calendar, under the rules you set: duration, buffer, minimum notice, and working hours. Across clinics or coordinators, slots distribute by round robin, least busy, or a priority order you define, and the confirmation lands as a real calendar invite.

An evaluation on the calendar, from "my doctor said I should start PT".

Marketing directors at PT groups win the click and cannot prove the visit. The conversion surface is a phone number, so the budget conversation with the CEO stays anecdotal.

One analytics home covers it. Conversion funnels run from visitors to conversations to completed goals, with top lead sources broken out by UTM source, campaign, and landing page, each with its own conversion rate. The referring physician and the preferred clinic are captured fields, so you can follow the same cut through to booked evaluations. Every number is clickable down to the individual conversation that produced it.

The referral report a surgeon's office will actually read, and a budget defense built out of booked evaluations.

Nobody puts an agent on a 60-clinic website on a demo alone. Your marketing lead wants to read what it says, your compliance lead wants the insurance and clinical-boundary answers in writing, and someone has to sign off.

Tars runs simulated patients against your real agent before launch: personas and goals driving multi-turn conversations, generated from your own content. Each is scored two ways, by deterministic code checks and by LLM-judge evaluators asking whether the question was answered, the right tools were called, and the patient got what they came for. You set the thresholds that gate a deployment, and after launch real conversations feed the same loop.

Your sign-off meeting reads evidence.
