Office Staff

Ted Schlimgen – Field Operations Manager

15 years with TJK Design Build.

Darin Rahn – Field Superintendent

Darin Rahn grew up in rural Wisconsin working on dairy farms, and for the last 30+ years, the construction industry has been his profession. During his first 15 years of construction, Darin worked in public works, primarily on water and sewer installation for new subdivisions and municipal public works reconstruction projects. For the past 15 years, he has worked with us on commercial and industrial buildings, including new construction and remodels. Working for a design-build company has given him the unique opportunity to oversee all aspects of projects from beginning to end. Darin enjoys spending time with friends and family, and in his spare time, he and his wife chase around after their two sons, attending all their sporting events and activities. He also bowls regularly in a local league, helps with a local youth bowling league, and can be heard rooting intensely for the Packers, Brewers, Bucks, and UW Badger teams.

Jacob Manke – Carpenter

Jacob Manke has over three years of carpentry experience and is excited to continue learning. Jacob brings a refreshing work ethic and is always eager to take on new responsibilities. He grew up in Sun Prairie, where he participated in various sports and the Boy Scouts. Jacob received his Eagle Scout badge in 2020 and, not long after, decided to start his carpentry journey in the residential field. He enjoys music, skateboarding, golf, snowboarding, disc golf, and hanging out with friends.

Tyree Starlin is a native of Chicago, Illinois, and an avid Bears fan. He has over 20 years of combined classroom and field construction experience. Ty attended Madison Area Technical College as well as Moraine Park Tech, where he honed his skills and the craft he’s grown to love. He’s been a lead carpenter in multiple residential and commercial construction projects throughout Madison and owned and operated his own remodeling company for nearly a decade. In his spare time, Ty enjoys cooking with his daughters and grandchildren, watching a good movie, or just kicking back and listening to some good, old-school rhythm and blues.
