History and overview
In 1995, the company's first location was opened in Denver under the name Driving Obsession. Two years later, it was re-branded as GOLFTEC (Technique, Equipment, Conditioning) and added two new locations in the Chicago area. Since then, GOLFTEC opened more than 200 centers worldwide and became one of the top employers of PGA of America Professionals, as well as a provider of golf club fittings.

Currently GOLFTEC offers clubs from Callaway Golf, Mizuno, PING, TaylorMade Golf and Titleist.

Partnership with Golf Digest Online
In May 2018, Golf Digest Online (GDO), the largest online / offline golf conglomerate in Japan, expanded its partnership with GOLFTEC.

The agreement centered on GDO's US entity, GDO Sports, Inc. acquiring majority interest in GOLFTEC with plans to merge the strengths of both companies to further grow the business globally. Existing GOLFTEC leadership remained in place.

Publicly traded on the Tokyo Stock Exchange and with 550 employees, GDO previously held a minority stake in GOLFTEC, operating 10 franchised training centers in Japan since opening its first in the upscale Roppongi district of Tokyo in 2012.
