Our story
From defensible-space work for neighbors to a growing crew running modern equipment across the foothills.
Founded in 2022 by Wyatt Wass as a one-man sole proprietorship, the company started out helping homeowners maintain CalFire compliance through defensible-space work. What began as a single tractor and a commitment to do right by our neighbors quickly became something more.
In August 2023, after winning its first public contract with the Eastern Madera County Fire Safe Council, Wyatt transitioned to full-time operations with the support of his wife Miranda and trusted contractor partners. That milestone turned a side project into a family business with a mission.
Peak has since grown with multiple tractors, trucks and employees, and added specialized services including horizontal directional drilling (HDD) for utility construction. We have stayed rooted in the same values we started with: hard work, honest pricing and a genuine care for the land and the people who live on it.

Our team
We hire motivated, self-driven individuals who take pride in doing the job right.
Every employee receives a minimum OSHA 10 safety certification before starting, with annual OSHA 30 training offered, and we coordinate with equipment manufacturers to train our crews on new technology as we add it.
That investment keeps our people safe, our work consistent and our customers confident — whether we are running a forestry mulcher, setting a septic system or steering a directional drill.
