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 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.
Dennis oversees TW Construction’s field operations and logistics. Drawing on his vast and varied experience in the field, he mentors TW’s superintendents and serves as a resource for our project teams. Dennis has been part of TW Construction for over 25 years and is held in high esteem by both clients and subcontractors for his leadership, high standards and problem-solving skills. In his spare time, Dennis enjoys hunting, golf, rooting for DC’s sports teams, and spending time with his family.
Kevin is responsible for leading and developing TW’s newest endeavor, a multi-family division that focuses on small and mid-size residential projects. Kevin also plays a key role in developing relationships with both clients and subcontractors and is frequently called on to assist project teams with complex and unusual situations. Kevin holds a Bachelor’s of Science in Civil Engineering from the Catholic University of America and a Master’s of Business Administration from the Kogod School of Business at American University. When Kevin is not at the office, you can find him outdoors, hiking and camping with his family and coaching Little League.
Dan leads TW Construction’s business development and pre-construction efforts. Drawing on more than 30 years in the commercial construction industry, Dan is instrumental in helping clients realize their goals while staying within budget. Clients often seek Dan’s counsel early in the pre-construction process due to his problem solving skills and knack for value engineering. A professor of construction science, Dan’s pursuits outside of work include teaching at Montgomery College, spending time with his family as well as home improvement projects and woodworking.
