Our Leadership

TW Construction is built from decades of experience in the industry. Before TW Construction became what it is today there were two men, Jerry Therrien and Donnie Waddell, who aspired to build their own enterprise. Years down the road with their strong leadership and devotion to TW Construction, they have built teams that create uncommon solutions for difficult problems.

Matt Maynard

President

Matt joined TW as a Superintendent in 2004 and managed daily activities and safety on his assigned sites. To build upon his field experience and continue his growth in the construction industry, he pivoted to the office working as an estimator and project manager for work he was awarded as well as negotiated work assigned. His role within the company continued to grow and he gradually climbed the ladder and became the VP of Operations, where he led the company’s estimating and project management teams. Matt now serves as President, having succeeded TW’s founders, Jerry Therrien and Donnie Waddell, who retired in 2021.

Matt grew up in Reston, VA and developed his competitive nature while excelling in multiple sports through high school. He played basketball at the College of Wooster prior to transferring and ultimately graduating from James Madison University (Go Dukes!). His lifelong motivation to win and succeed continues at TW as he builds upon and expands the company’s record of success.

Outside of work, Matt enjoys spending as much time with as possible with his wife, daughter and their two dogs in Herndon, VA. He also enjoys hacking up local golf courses and, in the process, donating golf balls to the local woods, creeks, and ponds. Matt’s favorite getaways are the Outer Banks and Deep Creek Lake.
