Report
Mr. Stromsodt,
Fritz Budig and the team from Grindstone Construction approached our build with the utmost in professionalism. Through the entire project duration Fritz and his team remained on, or ahead of, schedule even accommodating for multiple change- orders and plan revisions. Fritz and his Project Manager worked with all of the sub-contractors to produce a virtually seamless transition from contractor to contractor as it related to the "chronological map" for completion. Very professional outfit from very satisfied (2- time) client. Dan Wellman
