Mary Detwiler – Account Manager
A New York native…. and a J E T S, Jets, Jets, Jets fan, Mary has been in the Recruiting field since 2007. She started her career with a large National recruiting firm, cutting her teeth in the industry as a Staffing Manager before taking on the responsibility of running her own team. Mary then did a 2 ½ year stint as a Corporate Recruiter for a Fortune 200 telecommunications company before being called back to the agency world. Over the next five she rose to the role of Area Manager presiding over all of Colorado for another large National firm before deciding it was time to trade in the short-term “grow the business at all costs” mentality of the National firms for the more sustainable “do things ethically, consistently, and ultra professionally for the long-term, and clients and candidates will eventually beat a path to your door” mentality of High Country Staffing.
Having moved to Colorado from New York in 2001, Mary has embraced the Colorado lifestyle and enjoys the mountains and outdoor time with her husband Dave and 2 kids Leighton and Peter. She is a huge sports and music fan, and tries to catch both avenues live as often as possible.
Mark Duggan – Staffing Manager

Mark joined High Country Staffing in 2015 after spending nearly 4 years with Robert Half International as a Division Director.
Sports and anything competitive is right up Mark’s alley. He brings that competitive background and team oriented nature into his work and prides himself in being prepared for anything that comes across his desk. Mark truly believes in building strong relationships with his candidates and clients and cares about the wellbeing of both parties.
Away from the office, Mark spends as much time as possible with his wife, three children (Dominic, Emerson and Bryce), and his dog Reggie. They are all huge Denver Broncos fans and enjoy anything camping and outdoor related.
