Bob Williams, owner of Protech, worked for one of the largest music stores in the USA for twenty years, first as a bench technician, then as service manager. He founded Protech because he saw a need for a company that could provide sales and support for the growing high-tech audio, video and event staging requirements of the Washington, DC metropolitan area.
Today, ProTech can repair anything from vintage tube guitar amps to advanced high-def video projectors to professional digital studio recording systems.  We have installed state-of-the art systems and done maintenance and repair work for military bases, night clubs, houses of worship, schools and theater venues throughout Maryland, Washington, DC and Virginia.
Our clients include nationally known musicians, major corporations and houses of worship, recording and broadcast studios, and military bases as well as local musicians, DJs and home theater enthusiasts.

Protech’s commitment is to provide all of our clients with the highest quality service for the greatest value.
