    Associate, Team Leader

    Sam is a residential MEP engineering prodigy. You name the challenge and he’ll tackle it: ultra-low noise level requests, no ceiling space for ductwork, conflicts between the structure and building systems, inadequate heating and cooling, custom “party mode” settings. Sam’s brain is always about five steps ahead of the challenge at hand. He thinks so fast that while he is explaining something (say why you can’t locate a duct underneath a sprinkler head) he’s actually already considering the impact of relocating that very sprinkler head versus code-required coverage patterns and the implications it would have on overall fire safety. On the job, Sam is always thinking on the fly.  When unexpected issues arise, Sam outsmarts them every. single. time.

    Team Leader

    Scott was just simply cut out for a career in residential engineering, not the cookie cutter world of commercial MEP applications.  He lives for his days traveling from coast to coast, designing, observing, and testing custom systems in private homes and conjuring ideas to solve each distinctive, unconventional puzzle. Modestly unassuming, Scott approaches each project with an open mind and open ears.  He listens intently to homeowners’ special requests and strategizes for their integration into his designs. After much thoughtful deliberation, Scott explains his precise plan of action in great detail to our clients addressing their every need. Then he gets immersed in the finite details, fine tuning the comfort of each home to exacting specifications.  No matter how outlandish it sounds, you name it, he’s designed it (or if he hasn’t, he’s always up for the challenge at hand): HVAC control systems with custom text alarms and remote access, indoor backup generator rooms, walkway snow melt, wine storage rooms, indoor pool room humidity controls. On rare occasion, Scott is forced to deliver the news that although we can certainly jump through a lot of hoops, we can’t break the laws of physics. In his spare time, Scott picks things up and puts them down (sometimes weights, sometimes a 2012 93 pt. Tuscan Petit Verdot).
