Not a generic tool from a software company that's never run a call or a clinical rotation—MainStayEMS comes from the field and the classroom.
MainStayEMS was built by people who've spent their careers in EMS and the fire service—paramedics, firefighters, and educators.
We didn't come to this from software. We came to it from the field and the classroom, where we ran programs on a patchwork of spreadsheets, paper binders, and disconnected tools that never talked to each other. We lived the late nights before a site visit, the lost run sheets, and the endless re-keying of the same data.
So we built the platform we wished we'd had: one connected system that handles education, clinicals, skills, compliance, and communication for EMT and Paramedic programs—designed around how those programs actually run, and around the accreditation standards they answer to.
And it keeps getting better because we listen—the EMS and classroom instructors who use MainStayEMS every day tell us what works, and their suggestions shape what we build next.
Our mission is simple: give EMS educators their time back, so they can focus on what matters most—training the next generation of EMS professionals.
Meet the founder
Jay has been writing software since 1972, starting with BASIC and mainframe languages and working all the way to the modern web. He also spent 18 years as a firefighter, paramedic and driver engineer with Sarasota County Fire Department.
Today he is the EMS Clinical Director for EMT and Paramedic programs and a Florida-licensed Paramedic. Every day he runs the same clinical rotations, skills signoffs and accreditation prep that MainStayEMS is built to handle.
That mix is the point. Jay designed and built MainStayEMS himself: hospital clinical scheduling, ride-along processing, skills signoffs, grades, cohort graduation and compliance tracking, with encryption at rest and role-based access protecting student and clinical records.
What we believe
We've worked the calls and run the programs. MainStayEMS is built on what actually happens in EMS education—not guesswork.
Less time on paperwork means more time training the next generation. Every feature exists to give that time back.
CoAEMSP requirements and National Registry standards aren't an afterthought—they're baked into how the platform works.
No bloat, no buzzwords—just tools that solve real problems for EMT and Paramedic programs.
We listen to the EMS and classroom instructors who use it every day—their suggestions drive what we build next.
