Incorporated in 2008, Tri State General Contractors specializes in retail and commercial construction with licenses in CA, AZ, NV, HI, ID, UT, OK, NM and TX.

In the early 1990's Dave took his experience into the Retail Supermarket business and as Vice President of a prominent retail and commercial contracting firm, he helped grow that firm from a small commercial builder into a significant player in the retail construction industry. With Dave's strong leadership and know-how he has helped Tri State reach these same milestones. Assisting its retail clients with their most complicated projects is Tri State's specialty. Their ability to pre-plan complicated sequencing and navigate through tough project challenges from pre-planning to closeout is a large reason why Tri State's relationships and repeat business are so significant. Tri State's clients are confident that we will successfully perform and complete every project to their satisfaction, "on time" and "on budget".

All have grown up in the industry and have extensive backgrounds in all phases of construction. Tri State is very proud of the talented team they have in place and considers all of their employee's family.
