Mark Sakry

Northern GroundSource

Owner and President of Northern GroundSource in Brimson, MinnesotaMr. Sakry is a geothermal technical consultant who is specially trained and professionally credentialed by the Association of Energy Engineers (AEE) as a certified geoexchange designer (CGD). This program “is designed to recognize professionals who have demonstrated high levels of experience, competence, proficiency, and ethical fitness in applying the principles and practices of geothermal heat pump design and related disciplines, as well as to raise the professional standards within the field. ”Mr. Sakry has designed and installed hundreds of residential and light commercial cold-climate geothermal systems since 2001, specializing in advanced hydronic split (radiant/forced air heating and cooling) applications; high-efficiency, multi-stage/variable speed forced air system; pond loops; vertically bored ground loops; and advanced horizontal ground heat exchanger designs.Mr. Sakry has been an accredited member of the International Ground Source Heat Pump Association (IGSHPA) since 2001 andpresently holds special accreditation as an IGSHPA certified geo inspector (CGI). He was a founding director of the Minnesota Geothermal Heat Pump Association (MNGHPA) in 2008 and currently serves as president on its Board of Directors. Mr. Sakryis a frequent speaker and trainer at professional-technical conferences attended by architects, mechanical engineers, building contractors, GHP/HVAC installers, and building science professionals at both the state and national level.
