Sioux Falls Team Members

Aaron Siebrecht

Branch Manager

Aaron brings 20 years of construction experience to the Cullen team, including five years in the insulation industry. He graduated from Lake Area Tech with a degree in Construction and spent 15 years with Morton Buildings before joining Cullen.

Aaron enjoys being a part of every project, from start to finish, and loves watching buildings take shape. His favorite part of working in this industry is its variety, working on both commercial and residential projects and staying up on the latest designs. He admires his customers’ dedication to building a better product and his team’s commitment to being better installers.

Outside of work, Aaron enjoys spending time with his wife and kids, especially cheering them on at their sports events. His advice to those considering the trade: “The insulation industry is not the same as it once was, and the stigma that it’s super itchy is not the case anymore. Insulation plays a big factor in the construction world and having the right people and the right equipment can bring a lot of comfort to people’s homes.”
