Three Docs and a Dash Quartet

 “Three Docs” is a quartet consisting of a UWL professor, Brad Seebach, Holmen,  father and son team of Jon Williamson, Sparta, and son Marty of Onalaska. The three of them represent the docs. Our “dash” is co-director Eric Sorenson, of Onalaska.

Member One, Lead

Brad Seebach is an experienced barbershopper as well as an accomplished vocalist in our area. He also sings with the LaCrosse Chamber Chorale. With his vocal versatility he often lends his voice out to other quartets in need of a singer. Brad is a science professor at UW – LaCrosse.

Member Two, Tenor

Marty Williamson is definitely a chip off of the old block when it comes to singing the barbershop style. As a newer member of the Chordsmen Marty has a lot of repertoire to learn but his enthusiasm and talent will greatly benefit the chorus and quartet.

Member Three, Baritone

Eric Sorenson has been a chordsmen/co-director since 2010. He has sung in many quartets but hopes “Three Docs” will be become a long standing ensemble. Eric is a retired choral director teaching in the West Salem and LaCrosse School Districts. His first evening of singing with the Chordsmen began at 7:00 PM. He told his wife Barbara he would be home by 9:30. As he walked in the house at 12:15 AM his wife asked, “Well, did you have fun”?

Member Four, Bass

Jon Williamson is an optometrist in Sparta, WI. He has sung in many varied quartets often volunteering to sing other parts when needed. Jon loves to search out new and challenging songs for the chorus as well as “Three Docs”. Jon enjoys being a member of the Chordsmen music team and has played many outlandish characters in our shows.

Thick ‘N Thin Quartet

A love of barbershop harmony has kept this very active quartet together through the decades. These talented singers are often asked to fill in their part with other quartets in need of a fourth voice. Look for them to appear in every performance the Coulee Chordsmen Chorus presents.
