Don Grosh spent his formative years in his father’s workshop where he helped his father build sets for Hollywood films. Combining his practical skills with his interest in guitars, Don joined Valley Arts in North Hollywood in 1985. Don was part of the Valley Arts team that made guitars for top players like Larry Carlton, Steve Lukather, and Lee Ritenour.

In 1993, Don started Don Grosh Custom Guitars in the garage at his parent’s house in Santa Clarita, California. By 2001, Don’s workshop had made over 1000 instruments and expanded into a new shop in a rented industrial space in Santa Clarita. That new workshop allowed for a bigger team and greater production capacity. In 2005, Don relocated the business to Broomfield Colorado, just outside of Denver.
