From 1968 to 1985 Dave held a variety of positions at Borg Warner Corporation. After joining Borg Warner Chemicals in 1968, he held positions in Finance, Sales, Production and Marketing. In 1982, Dave moved to the York Air Conditioning division of Borg Warner Corporation where he was Vice President and General Manager of the Engineered Machinery Division.

Our Team


Not only do we say our personnel is the most highly trained team in the industry, we back it up. In addition to the require EPA, OSHA and HUD training, AST requires its employees to attend a 40-hour Hazwoper program, mold, bacteria and other microbial training, and the 10-hour OSHA construction-training course. Our dedicated employees average over 10 years experience in the industry. Then we take all of that training and experience and put it into action. We take great pride in not only our attention to detail, but our commitment to deliver exactly what we say we are going to deliver. You won't find us continuously changing our bid throughout the process of the project...or issuing costly change orders. What you are promised is what you get; and what you get is second-to-none service combined with extensive experience and pride in a job well done.
