ABOUT
Colorado-Trained Excavation Experience, Now Focused on Upper Peninsula Properties
Led by Lee Poole
Lee brings excavation training from Beaumont Excavating in Colorado and over 15 years of construction and property management experience. He runs Cornerstone hands-on – you work directly with the owner on every project, from estimate through completion.
Built on Real-World Excavation Training
Cornerstone Property Services is built on professional excavation experience gained at Beaumont Excavating in Colorado, now applied to residential and commercial properties across Michigan’s Upper Peninsula. The same problem-solving approach that handled Colorado mountain terrain now solves drainage, grading, and access problems in Marquette County.
How Our Work Took Shape
Lee left Colorado and came back to Michigan when family priorities changed. What started as property management for a client’s second home evolved into construction work, then excavation services when local demand became clear. Cornerstone handles the work that keeps Upper Peninsula properties functional—drainage that floods foundations, gravel driveways that wash out every spring, land that needs proper grade before building starts. The work matters because your property matters. We show up, do what we said we’d do, and solve problems that don’t fix themselves.
