Daren approaches his transportation design work with an understanding and appreciation of constructability and integration into the community. His transportation engineering experience includes geometric design of roadway projects, ADA design, intersection design studies, design of public improvement projects, cost estimates, construction inspection, and surveying.

Early in his career, Daren had opportunities to work in other civil engineering disciplines, including construction engineering and land development. This experience informs his approach and enhances his design skills. Daren brings an infectious energy to his teams through his fun and engaging personality.

Daren’s favorite things to do (besides working at Isthmus, of course) typically involve music — listening, watching, advancing his playing skills, adding a new instrument to his repertoire, or reminiscing about his glory days as a sousaphone player in the University of Wisconsin Marching Band.
