Aaron is passionate about using technology to deliver practical, innovative infrastructure solutions. His expertise spans site evaluation and planning, stormwater management, feasibility studies, public involvement, and utility coordination.
Aaron lives in Eden Prairie, MN, with his wife and two daughters (pictured below). Outside of work, he enjoys playing pickleball, mountain biking, and spending time with friends and family, whether around a fire or at the table for a board game.

Adam Pawelk
Adam Pawelk served as vice president of HTPO and led the construction management department, bringing civil engineering experience to public and private projects. Since joining HTPO in 2004, Adam has distinguished himself through his attention to detail, quality of work, and strong project management skills.

Additionally, Adam served the Watertown, MN, City Council, providing him with a unique perspective on municipal needs and infrastructure challenges.
A longtime resident of Watertown, Adam enjoys working on home projects and following Minnesota sports, though he knows the highs and lows that come with being a Twins and Vikings fan. His dedication to engineering, leadership, and community involvement makes him a valued addition to HEI’s group of shareholders.
