Board of Directors

Roxanne Powell – President (2021)

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 41 years as a member of Sweet Adelines and Harmony, Inc. and is a founding member of the Bella Nova chorus in Northern Virginia. She founded and directs Full Circle, a mixed voice barbershop ensemble in Ellicott City, Maryland, and is the associate director of  ShowTime Singers, a mixed-voice community chorus of 55 men and women. She has sung, as well, in three SAI medalist choruses — Mission Belles, Arundelairs, and Elkridge/Harbor City Music Company — and in several quartets, most recently Joint Venture Quartet who retired after 25 years entertaining over 450 audiences.

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.

Carlos AguayoCarlos Aguayo – Director (2022)

After singing in an auditioned, 16-voice jazz choir in high school, where he got his first taste of barbershop singing such classics as Coney Island Baby and Walking Through The Park One Day, Carlos felt right at home returning to the risers with the Duke City Sound in Albuquerque in 2009.  From the first tags sung after that first rehearsal, he knew he had found his tribe among the BHS, and jumped in with both feet.  His first quartet, Paramount, formed in 2011, and were novice champs their first year out, and were Rocky Mountain District’s 3rd place quartet champs in 2012.  Carlos moved to Portland in search of more fruitful opportunities in the burgeoning high-tech sector, and he now sings bass with Hometown Harmony and the Bridge Town Sound chorus.

Carlos studied computer science and engineering at UC Davis in California, and works as a systems architect.  He also loves to get away from glowing screens in favor of hiking, bicycling, skating, or, more often than not, singing.  He serves on the board of the BHS Portland Metro Chapter as  Program Manager, and has been advocating for mixed harmony opportunities since well before connecting with the folks who would become founding members of the MBHA board.  He lives in Portland with his wife, Clara, who also makes beautiful music at every opportunity.
