About Us


Jeff Gjertsen P.E.
Director of Engineering

Jeff joined MACSAX at the beginning of 2017 to work on the solid modeling and CNC manufacturing of the mouthpieces. Before coming to work at MACSAX, Jeff spent 10 years developing and manufacturing precision dosing microfluidic drug delivery systems. He has brought that precision manufacturing and design experience to help us produce the highest quality saxophone mouthpiece you can buy. Jeff is a licensed Professional Engineer in the state of Texas, Registered Patent Agent, and has a mechanical engineering degree from The University of Texas at Austin. Jeff has played the trumpet starting in the sixth grade all the way through college where he played with the Longhorn marching band. When asked why he did not pick the saxophone when selecting his instrument in middle school, Jeff said "It had too many buttons. The trumpet only has three buttons which means I can concentrate less on which buttons to press and more on playing louder than everyone else."
