A Little About Us

Welcome to Team Horsepower (thp)

THP is built on a foundation of strength and commitment to excellence.

A team of employees once noticed they consistently went above and beyond their peers, so they proudly coined themselves “Team HorsePower.” Then, when Craig Medley branched out to start his own company, he carried that same spirit of accountability, work ethic, and pride forward. From that legacy, THP—Team HorsePower—was born.

THP Mechanical is far from an ordinary MEP contractor. While many companies keep their eyes on the bottom line, THP’s true focus is on its people. Ask President Craig Medley what drives him, and his answer isn’t about the number of projects or revenue earned—it’s about building a unified team built on respect, trust, and admiration.

As we continue to grow, we remain steadfast in delivering the highest quality to our clients and our community for years to come.

At THP, we exist to excel.
