DMG Corporation was founded in 1967 by Al Dokter, Don Miller, and Bill Gebbie — to represent the finest HVAC products in the Greater Los Angeles area. Since then, DMG has steadily grown from a partnership of three into a thriving sales team of over 70 members. Starting with our first president, Bill Gebbie, through the tenures of Bob LeClercq, George Orff, Ron Sweet, and now under our current president, Steve Weston, the focus of DMG has remained the same: offering our clients personalized engineering support and project management, while providing equipment and services which best fit their HVAC needs.
