About The Author

Founder. Builder. No Plan B.

For ten years, Scott worked jobs that looked stable on the surface—finance, insurance, corporate roles—but always felt like they belonged to someone else’s vision. He wasn’t building anything of his own, and the day-to-day offered little more than repetition.

After a personal and financial low point—including a Chapter 7 bankruptcy—he found himself starting over with almost nothing. A friend gave him a shot in roofing sales. Two small jobs in, someone wrote his commission on a napkin at a diner table. The number was more than he’d made in weeks. That’s when he saw what this industry could offer—not just income, but real ownership over your success.

From there, everything changed.

Scott built this company to give others the same shot he got. He doesn’t look for perfect résumés—he looks for people with drive, character, and something to prove. His goal is simple: train in weeks what took him a decade to learn, and create a path to success that’s real, not theoretical.

Today, he leads one of the fastest-growing roofing and solar teams in Texas—but he’s still walking jobs, coaching reps, and checking in with homeowners. Because no matter how big the company gets, the mission stays the same: do the job right, take care of your people, and never forget where you started.
