Green Mountain Guitar is the result of a life long dream of Glen DeRusha's. Growing up in Cloquet, Minnesota, he loved to play guitar. He also loved to build things with wood. He worked for years crafting furniture and cabinets for other people.

Glen attended Roberto-Venn School of Luthiery in Phoenix, AZ. There he learned the skills and techniques required for building guitars. He also attended the The Chimney Violin workshops in Tucson. After several years of restoration and repair work, he was ready to start building.
