My name is Dennis Tresner. With the invalueable help of my wife Mary we run Black Lake Buildings. But, it has not always been that way. At Black Lake Buildings, our families have been construction for many years. With our portable buildings first starting in Arkansas in the 1960's. moving to North Carolina for a short time, and moving to Alaska in the 1970's, there are thousands structures in a number of states now. At the time, there was a real need for quality buildings in the Mat-Su. Quality has always been the priority.
