Sales Manager
A Michigan native with seven years in sales at Strawberry Solar, Seger earned a Bachelors of Sciene in Sustainability degree from Arizona State University, which sparked his passion for clean energy and conservation. He’s a big fan of Detroit sports, weekend golf, architecture—and his dog, Oreo, who’s pretty sure he runs the show.
Gunnar Groesbeck
Solar Designer & Sales Associate
Gunnar grew up in northern Michigan, fostering a love of the outdoors. After getting a Mechanical Engineering degree from University of Michigan and working as an automotive engineer for several years Gunnar realized that he needed to work in better concert with nature. He received a Masters in Sustainable Energy Engineering from the University of Stockholm in Sweden and when he’s not chasing his kids around, he is happily helping people and businesses realize their solar potential!
