Josh Pingel

Project Manager

Josh Pingel, originally from New Hampshire, started his construction career in the hotel renovation industry which gave him a keen eye for detail and finishes on a commercial level. Afterward, he expanded his skill set and moved into a position for commercial framing and drywall which gave him the edge in overseeing larger scale projects. His work experience translated into SDB’s carpenter team as a site superintendent. When he is off-site or out of the office, Josh likes to hit the slopes and snowboard as much as possible. 

Derek Roth

Design Manager

Derek has been in residential construction for more than half of his life. He started working under his father fixing up dilapidated properties in Cincinnati, Ohio. After graduating from Miami University he knew he wanted to get back into construction so he moved to Tennessee and began flipping homes. His goal was to always move out to Colorado and in 2018 he was finally able to make the move with his girlfriend Julia. In his free time you can catch him camping in the summers or climbing 14ers with his dog Reggie. In the winters if he is not working there is a good chance you can find him in the mountains on his snowboard. 

Luke Zygmunt

Site Supervisor

Born and raised in Grayslake, IL. Luke was brought up with a tool in hand learning his trade from his family who were a wealth of construction experience and knowledge. A bit of a renaissance man, Luke loves to cook, bake, paint, play music, and build things. He craves the outdoors and adventure is always calling him which is ultimately how he found his way here to Colorado. Luke plans on building his own self-sustaining homestead somewhere in this mountain paradise. But until then, he enjoys advancing his skills within the construction industry and working with SDB.

Tommy Zygmunt

The reason Tommy moved from Illinois to Colorado, in his own words, is “Because of everything I love is here”.  And that seems to check out, he has an appetite for mountains, amazing food, thriving music scene, hunting, fishing, and so on. As we all know, Colorado has them all in spades. In his free time, Tommy enjoys writing and producing his own music, snowboard, hiking, and just about anything that involves adventure. Tommy hopes one day to own some land, build a home, and build a music studio in this wonderful State.
