I have been in the business of piano technology and tuning for about 23 years. My father, the late Clifford Johnson, was the piano tuner & technician for the Minnesota Orchestra and was professor of Piano Technology at the University of Minnesota, MacPhail Campus during the 1960s-70s. I am also an Associate Member of the Piano Technician's Guild.

At the moment I have about 325 residential clients. I'm always open for more and I am usually able to do "last minute" tunings.

I am a piano humidity Field Expert! I have installed over 25 piano humidity systems manufactured by the
Dampp-Chaser company. Check their site and save your piano from humidity related problems!

I have been honored to tune for many great jazz & pop artists appearing in Minneapolis & St Paul. Some of them include;

Mose Allison, Tori Amos, Lynne Arriale, The Bad Plus, Kenny Barron, David Benoit, David Berkman, Shelly Berg, JoAnne Brakeen, Dave Brubeck, Bill Carrothers, Bill Charlap, Jon Cleary, Chick Corea, Brian Culbertson, Dr. John, George Duke, Eliane Elias, Russ Ferrante, Philip Glass, Benny Green, Larry Goldings, Arlo Guthrie, David Hazeltine, Imogen Heap, Nachito Herrera, Eddie Higgins, Hiromi, Fred Hirsch, Bob James, Jan Kasperson, Geoff Keezer, KEM, John Legend, Ramsey Lewis, Jeff Lorber, Bobby Lyle, Manhattan Transfer, Ray Manzarak, Phil Markowitz, Keiko Matsue, George Maurer, Brad Mehldau, Mika, Mulgrew Miller, Jason Moran, The New Standards, Pinetop Perkins, Danilo Perez, Marcus Roberts, Gonzalo Rubalcaba, Patrice Rushen, Boz Scaggs, Peter Schimke, Evan Shinners, Ben Sidran, Esbjorn Svensson, Tanner Taylor, Butch Thompson, McCoy Tyner, Chucho Valdez, Jon Weber, Benny Weinbeck, Kenny Werner, Randy Weston, Yellowjackets, Rachel Z, Denny Zeitlin...
