Our Story, Our Beliefs

GR Technologies came about as a solution for two trumpeters who were struggling with their own playing issues due to equipment mismatches.
In 1999 Gary Radtke (GR) and Brian Scriver were active trumpet players. GR was dealing with dental reconstruction and was trying to get his chops back. Once a top call player in the Milwaukee area, GR could barely play and was struggling to find his way back. Trying numerous mouthpieces from various manufacturers just caused more frustration.
Brian Scriver had a group called "Primal Therapy" in Toronto Canada, and even though this group was actively gigging, he was still on the mouthpiece and horn safari trying to find solutions to his playing issues.  Together GR and Bri formed GR Technologies because they believed that they could help trumpeters like themselves achieve a playing solution and concentrate on what they really loved; making music with the trumpet.
Gary Radtke has an extensive resume which oddly enough, makes him the perfect candidate to making the finest mouthpieces in the industry and more importantly, troubleshooting trumpet playing issues.

The Story Continues...

GR using his ability to troubleshoot, his design knowledge, and his superior machining ability to develop a design program unparalleled in the brass instrument manufacturing industry. This program eliminates all Discontinuities
in the design of mouthpieces and potentially in brass instruments themselves. By doing this, the musician is able to play music with a fatter, fuller tone without having to manipulate due to inefficient designs as found in other manufacturer's mouthpieces.
Most importantly however, GR designed a fool-proof method of testing equipment to insure a match between player, mouthpiece, and horn. A match that is essential to a quality musical performance. GR has uses this method to solve playing difficulties of some of the world's finest players! Yes, everyone has playing issues at one time or another!

By solving their own playing difficulties and believing that they could improve the musical experience of trumpeters all over the world, GR and Bri have developed GR Technologies into what it is today...the foremost brass instrument mouthpiece manufacturer in the world. We believe our fitting system, products, and customer service to be the best in the industry.
