Janine Roberts – Vice-President (2025)

A passionate barbershopper with over two decades of Sweet Adelines experience as well as competing with various quartets, Janine took over as Membership Chair for the Mixed Barbershop Harmony Association in November 2017 and was appointed to the Board of Directors in January 2018.  In 2019 she stepped out of the Membership Chair role and into Governance and Bylaws and then “created” the new role of Project Manager in 2021 to bring some of her “other life” to MBHA.

After seeing an ad in the local paper for “free singing lessons,” Janine joined SAI Region 26 Westcoast Harmony Chorus in late 1995. She transferred a couple of years later to Lions Gate Chorus, where she held numerous Music and Management Team positions.

In 2005, she attended the Buckeye Invitational and caught the mixed barbershop bug. She sang briefly with mixed quartet By Invitation Only, which included members from Manhattan, NY, Indianapolis, IN, and Vancouver, BC, Canada. She is also a founding member of Afterglow Quartet, a mixed quartet based out of the BC lower mainland which started in 2003 (Janine was replaced in 2006 when she left barbershop but has continued to sub in for holiday performances over the years).

Following a 12- year hiatus from barbershop during which she served on the board of a newly formed non-profit and continued her administrative and management career, Janine returned to barbershop as a sub in for Afterglow at the Evergreen Division 2 contest in the spring of 2017 which was such an awesome experience, she decided to start a new mixed quartet and Full Measure was born.  After many performances and and an invite to the 2020 BinG! World Mixed Quartet Competition to represent Canada, COVID hit and unfortunately, Full Measure decided on an “indefinite hiatus”.  She’s still on the hunt for a new Mixed Quartet – so if you’re interested (and in the Pacific Northwest area) definitely get in touch.

Among the experiences she counts as highlights of her life are:

  • traveling to England and Scotland with mixed chorus Pacific Coast Sound in June 2017;
  • starting the mixed quartet Full Measure in late spring of 2017;
  • re-joining Lions Gate Chorus in November 2017; and
  • getting the opportunity to serve as MBHA Membership Chair and being appointed to the Board of Directors.
  • Winning a 2nd place International Sweet Adelines Chorus medal with Lions Gate chorus in October 2019
  • Being invited to represent Canada at the 2020 BinG! World Mixed Quartet Competition in Dortmund, Germany (unfortunately cancelled due to COVID)
  • Singing with 3 SAI choruses in 2022 – Pacific Edge Chorus (Maritime Tour), Westcoast Harmony Chorus (competing at SAI International September 2022) and Lions Gate Chorus

Roxanne Powell – Immediate Past President 

Roxanne has over 40 years of leadership and management experience as a teacher, religious education assistant director, and managing editor of two community newspapers. She has been an active quartet and chorus singer for 44 years as a member of Sweet Adelines and Harmony, Inc. and is a founding member of the Bella Nova chorus in Northern Virginia.

She is a founding member of the Women’s Harmony Brigade. In her spare time she serves as the editor of Harmony, Inc.’s semi-monthly newsletter HI Note and the semi-annual magazine, The Key-Note.

In her youth, Roxanne was a wall flower who never got to swing. (Except in the red velvet swing at the San Francisco Steak House . . . but we don’t talk about that.) She poured the punch and chatted with all the guys who were too shy to ask the gals to dance. Roxanne sings bass with the gals and bari in mixed ensembles. She is married to Dick, a fellow barbershopper (and Immediate Past President of the Barbershop Harmony Society) and the only man she ever found who talks faster than she does. The mother of seven and grandmother of five, she spends her time singing and helping others to find their voices in song.

Lured into the first meeting of the Mixed Barbershop  Harmony Association in 2016 by Gerry Borden, Roxanne was immediately hooked on the idea of spreading the joy of barbershop harmony beyond the bounds of traditional single-sex ensembles. She and Dick are charter members of the organization and are fervently committed to its successful growth.

Roxanne and her husband live in Crofton, Maryland. She can be reached at rpowell@mixedbarbershop.org.
