Roger Olsen and his crew did an excellent job putting in a large drainage ditch on my hillside. He responded quickly and was able to get the job done before the big snow storm!

These guys are amazing! Whenever I need a mountain moved, concrete poured.. basically anything out of my personal capabilities when running solo, they are my go-to. Paul is amazing to work with. He will come over to survey the job before hand and then give ideas on how it should be tackled with options to choose from. He's always on time and the jobsite is clean and tidy when his crew is done. One of the few companies I feel good about giving my hard-earned money to because I know the job was done right.

Roger and his crew put in a drive way and an area for a pickleball court on our property. He was very knowledgeable about the placement of the court and road for drainage and aesthetics. My property looks great. Roger will be my first call for any of my families excavating needs.
