"We had a great experience designing and building our home with Dennis. His attention to detail provided us with a highly functional, custom home."

D. Birkholz

"Cornerstone's renovation experience provided the exceptional craftsmanship required for our project. Our combined efforts were recognized by being given a Missoula County historical preservation award. We continue to call upon Cornerstone's experience for construction projects."

R. Holt

"We chose Cornerstone for it's outstanding reputation, but it wasn't until Dennis built our home that we realized just how good he was. The special touches and beautiful craftsmanship are evident, and envied. After nine years, strangers still knock on the door to ask who built it. Talk about pride of ownership!"

C. Nichol

"We found the most awesome lake front property in Missoula County and the challenge was finding a builder who could help us realize our long held dreams. Cornerstone exceeded our expectations and we now have the most unique and beautifully custom lake cabin to share with our family for generations to come."

M. Carpenter

"When my husband and I decided to build a home 8 years ago we were warned by many of the hassles and headaches that we would face. Dennis made the process a joy. The home is everything that we desired. Dennis took my ideas (including a red kitchen island), and made them work. His understanding of the building process was outstanding and he guided us through the entire process."

W. Bush

"We purchased a Cornerstone house a number of years ago and have enjoyed Dennis’ continued efforts to improve, warrant, and support our exceptional home. The unique finish and design qualities are commented on by all who visit. We value our house as much as our relationship with Dennis."
