Doug and Katie Mosier

At Glenrock Blue we believe in working together with you to provide the best possible refinishing and restoration services for your firearm. Our attention to detail and commitment to quality endure as we continue in the tradition of fine craftsmanship you have come to trust.

Originally founded in 1994 by master gun bluer Phil Filing, Glenrock Blue quickly earned its reputation as a high-quality custom firearms refinishing company. Recognizing the need for a successor in his craft, Phil brought Doug Mosier into his shop as his apprentice in 1999. Since that time, Doug has become a true craftsman in his own right, and continues the tradition of excellence that has given Glenrock Blue its longstanding reputation as one of the best refinishing companies in the country.

Doug Mosier is owner and primary craftsman at Glenrock Blue.  He has over fifteen years of experience in firearms refinishing, having trained for over a decade with master gun bluer and Glenrock Blue founder Phil Filing.

Katie Mosier joined Glenrock Blue in March 2010 as the shipping and receiving clerk.  She now also performs quality control, manages the office and keeps the books.
