Meet Austin Donogh

Growing up I had dreamed of running my own company. My dream became a reality, when I opened my septic and excavation company in Spokane Washington. Soon moving to Peshastin Washington, we then began servicing all surrounding areas, Leavenworth, Wenatchee, and Chelan WA. I made myself a goal, I wanted to work the hardest I could and strive to provide high quality affordable work. With my love for the Lord, I insisted my team uphold the utmost integrity with each and every job. Keeping all work honest and fair, while keeping communication throughout the project clear. Our privilege now is providing the community with a high quality, affordable septic and excavation service, that will always ensure outstanding work. 

Colossians 3:23

"whatever you do, work at it with all your heart, as working for the Lord, not for human masters"
