The First 90 Days: Onboarding a New PT the Right Way

Part 9 of The PT Hiring Blueprint. The offer letter from Part 8 is signed. Now the real work of hiring begins — and most of it happens in the first 90 days, whether you plan for it or not.

Here's a pattern we see constantly: an owner puts enormous effort into recruiting and interviewing, then treats the new hire's first week as "shadow a coworker for a couple days and jump in." That gap — intense pre-hire effort, minimal post-hire structure — is where a lot of good hires quietly become early resignations.

The 90-Day Ramp Schedule

Don't hand a new hire a full caseload on day one — and don't leave the ramp-up undefined either. A written schedule removes the guesswork for both sides:

• Days 1–14: shadowing, systems training (EMR, scheduling, documentation standards), and a partial caseload at roughly 40–50% capacity
• Days 15–45: increasing to 70–80% capacity, with a senior clinician available for real-time questions on complex cases
• Days 46–90: full caseload, transitioning from daily support to the regular weekly check-in cadence

Structured Mentorship

Assign a specific mentor — not "the whole team is here for you," which in practice means no one is. The mentor's job is narrow and concrete: be the first call for clinical questions, review a sample of documentation weekly for the first month, and flag concerns to the owner before they become bigger issues.

This matters even more if your pipeline leans on new grads, as discussed in Part 5 — a strong mentorship structure is what makes a new-grad-heavy hiring strategy actually work.

KPIs to Track

• Visit volume against the ramp schedule — are they on pace, ahead, or falling behind?
• Patient retention/rebooking rate — a strong early sign of patient rapport and clinical confidence
• Documentation timeliness — late notes early on often predict a documentation habit problem down the road
• Mentor feedback — qualitative, but track it in writing weekly rather than relying on memory at the 90-day mark

Tracking visit volume alone misses the early warning signs the other three metrics catch.

The Weekly Meeting Cadence

A 15–20 minute weekly one-on-one for the first 90 days, tapering to biweekly or monthly afterward, catches small misunderstandings while they're still small. Use it to review the KPIs above, ask what's going well and what's frustrating, and confirm the ramp schedule is still realistic.

Owners who skip this step often don't hear about a problem until the new hire is already updating their resume. Owners who keep it find out in week three instead of month five — while there's still time to fix it.

Frequently Asked Questions: Onboarding a New PT

How long does it take a new physical therapist to reach full caseload?

Most new hires take 60–90 days to ramp from a partial to a full caseload, assuming a structured onboarding plan with scheduled mentorship check-ins. New graduates typically take toward the longer end of that range, while experienced hires with similar caseload types can ramp faster.

What KPIs should you track during a new PT's first 90 days?

Track visit volume against their ramp schedule, patient retention/rebooking rate, documentation timeliness, and qualitative mentor feedback from weekly check-ins. Tracking these together — rather than visit volume alone — catches problems like rushed documentation or poor patient rapport before they become ingrained habits.

How often should you meet with a new PT hire during onboarding?

Weekly one-on-one check-ins for the first 90 days are the standard most coaches recommend, tapering to biweekly or monthly after that once the hire is fully ramped. Weekly meetings during onboarding catch small misunderstandings before they compound into frustration or an early resignation.
