Second Door Health

Musculoskeletal care is one of the most common and expensive issues in healthcare—driving billions in wasted spend, missed workdays, and unnecessary interventions every year. Patients are frustrated, employers are overwhelmed, and physical therapists—the providers best equipped to help—are stuck in a system that doesn’t reward their value. We started Second Door to change that. Founded by the team behind Strive Labs and WebPT Reach, we’ve spent over a decade building tools for rehab therapy and working inside the system. What we saw was a widening gap between clinical value and financial reality. PTs don’t just need more patients—they need a better model. Second Door helps clinics grow smarter, diversify revenue, and get paid fairly. We focus on the full business equation: patient volume, visits per case, and revenue per visit. Our tools open a second door into the clinic—one that doesn’t rely solely on traditional insurance, but still delivers high-quality, reimbursable care. We believe physical therapy should be the first step in MSK care—and that building a better system starts by supporting the people who already know how to fix it. That’s what Second Door is here to do.
