Board of Directors Biographies


Kathy Czerny, President

Music has been a part of Kathy’s life for as long as she can remember.  Her grandmother was her first teacher, and Kathy gave her first solo performance at the age of 2 at her mother’s alumna sorority fundraiser.  Kathy has been mixing music and fundraising ever since. She grew up in Utah, a hotbed for music and the arts, and was lucky to have a rich musical upbringing. Music has opened so many doors for Kathy – including touring Europe in college, meeting her husband, and ultimately providing her with a wonderful career. 

Professionally, Kathy served as the Executive Director and President for two large community music schools on the East Coast for over 30 years. The first one grew from a grassroots school, merged with the Rhode Island Philharmonic and is now the model orchestra/school in the country. In 2020, Kathy retired from South Shore Conservatory, one of the largest community music and arts schools in the country. At the height of the pandemic, Kathy left one daughter and son-in-law in Boston to move near her other daughter, son-in-law, 3 grandchildren, mother, sister and niece here in Colorado!  Kathy’s niece, Penelope, joined the Boulder Children’s Chorale and is loving it! 

Kathy is looking forward to bringing what she has learned in her 50 years in arts management to the Chorale and hopes that her experiences can be of benefit to the organization.

Greg Herring, Treasurer

Greg has been an active member of the Boulder Chorale for the past twenty-four years. He served previously on the Board of Directors for six years, and rejoined the current board three years ago, assuming the Treasurer position in the spring of 2021 and beginning his current term that year. Between these two periods on the board, Greg served for many years as the concert manager. In addition to high school and college choral experiences, Greg sang in church, community, and small ensemble choirs before joining the Boulder Chorale in 1999. Greg is a former network outsourcing project manager having retired from AT&T in 2019.

Laurel Seppala-Etra, Secretary

Laurel has been a member of the Boulder Chorale for over twenty years! Her musical life started as a child singing in church and school choirs and continued into college where she toured with her university choir in Europe. She also had the opportunity to sing Mahler 2 with the Pittsburgh Symphony Orchestra. After taking a break for several years, Laurel returned to singing when friends encouraged her to join the Chorale; her first concert was singing Beethoven 9!

Laurel graduated from Penn State with a B.A. in English/Education. Her work background is varied and has included administration, education, and a career in travel. After 9/11, Laurel lost her job in the travel industry and went back to school and earned an M.L.S. from Emporia State University. She has worked as a librarian, most recently at the Boulder Public Library. Laurel is recently retired. In the past she has held leadership positions in AAUW. Currently she is the co-chair of her church’s Worship Team.

All through her life in Boulder, the Chorale has been one constant that has brought her joy; Laurel loves singing different music and socializing with other choir members. She has volunteered on the Grants Committee, as the Music Librarian, and as Secretary of the Board.

Laurel revels in reading, travel, hiking, film, and attending various cultural events. Laurel and her husband live in north Boulder. They enjoy visiting their combined three children and four grandchildren where they live in Oregon, DC, and South Carolina.


Susan Arends, Director

Susan Arends joined the Boulder Chorale in 2020 during the online COVID year.  She has been part of choral groups with Church of the Resurrection in Leawood, Kansas for over 20 years and missed being part of a choir when she moved to Boulder in 2019.  Susan has three children who all participated in choral activities while living in Kansas.  Susan sings with the Chamber and Concert chorale and currently serves as the Chorale’s membership/volunteer coordinator.  It brings her joy to work with an organization with singers of all age groups.  Susan formerly worked as an assistant children’s choir director at Resurrection and currently substitutes for the Boulder Valley Schools.  If she’s not rehearsing, she’s skiing, doing yoga, walking her dogs or attending a concert.

Jackie Stone, Director

Jackie Stone has been a musician and vocalist her entire life. From a young age she started on piano, violin, guitar and sang with the Civic Youth Chorus of Detroit. She performed in collegiate a cappella at Grand Valley State University during her college years and is currently a member (alto) of the bFlatirons A Cappella group, where she also serves as their Business Manager. Since becoming a mom, she always hoped her children would take an interest in music and much to her delight, her son is now a very enthusiastic member of the Boulder Children’s Chorale in the Piccolini Choir. 

Jackie is thrilled to be a new member of the Boulder Chorale Board! With a background in non-profit work and business management of a musical group, she is excited to leverage her skillset to oversee the Chorale’s corporate sponsorship program. She is looking forward to creating partnerships with local businesses and furthering the mission of the Boulder Chorale through these relationships.
