Dan was raised in the greater Roseville, California area and attended the University of California, Davis, where he studied economics and sociology. Frey began his career at a venture capital firm where he excelled at sales and was ranked top salesperson every year he was with the company. Always on the lookout for new opportunities, Frey learned of a new process being utilized in Canada to restore failed dual-pane windows. Recognizing the potential for such a service in the United States, Frey launched The Glass Guru (originally Glass Wizard) in 2004. After three years of rapid growth and development, he franchised the company in 2007.
Frey was recognized by Glass Magazine in 2009 as one of the most influential 30 Under 40 in the glass industry as well as Sacramento Business Journal in 2011 as one of the Top 40 Under 40 business people from the Sacramento Region. Outside of work, Frey enjoys 4x4ing, backyard gardening and acting as a human jungle gym for his three young children. He considers himself a personal development enthusiast and is fond of listening to audiobooks and podcasts. Frey lives with his wife, Joy and children in Loomis, California, along with their two dogs, 5 chickens, and their goat named Jeff.
