Board of Directors

The members of the Board of Directors come from diverse backgrounds and experiences, but share their passion for the choral arts. We are always seeking new Board members whose skills complement those around the table. The OCWC’s Board is both a working board and a governing board, and board members give generously of their time, talent, and treasure. Board terms are three years, but shorter terms to fill open seats may be available. For more information about serving on our board, click here to download our current board service package.

Mary C. Langsdorf, President of the Board

Mary C. Langsdorf, President

Mary Langsdorf is the founding Board president, and hosted the original planning meeting for the group that would become the OCWC in the summer of 1997. A life-long chorister, she began singing in the church choir at age seven when her older sister convinced the choirmaster to take her a year early because she already knew most of the hymns. Although she never studied music privately or pursued it in college, choral music has always been her passion, and a source of joy. She has been singing with the OCWC since the first rehearsal.

Mary retired from her position as Senior Vice President of Finance at PacifiCare Health Systems, Inc. in 2001 to spend more time with her family after nearly thirteen years of progressively responsible positions in the corporate finance department. Prior to PacifiCare, she worked as an audit manager for Ernst & Young, LLP. Mary holds a Bachelor of Science degree in international management and accounting with minors in economics and French, and was licensed as a CPA in the state of Connecticut. Since her retirement, she has devoted much of her time to learning about the nonprofit sector and serving as the OCWC’s volunteer executive director.

Mary and her husband, Bill, make their home in San Juan Capistrano. Their daughter Meghan,  her husband Eric, and their grand-dog Penny are exploring city life in San Francisco. Their daughter Mary Eileen, her fiancé Joshua, and their grand-dog Luna live in Vancouver, Washington. When she isn’t singing, Mary enjoys walking on the beach, traveling (when it’s possible again!), and creating food for her family and friends that is both healthy and beautiful.

Marjorie A. Beale, Tours and Commissioning

Marjorie Beale has been a member of the OCWC since 1998, and has served on the board for six years in various capacities, including chair of fundraising, and more recently, director for touring and commissions.  An Orange County native, she got involved in choral singing as part of the Crystal Cathedral’s youth chorus, and joined the OCWC during its first year.

Marjorie served as a faculty member in UC Irvine’s Department of History during the 1990’s, teaching European intellectual history and critical theory, and was educated at MIT, Harvard, the Institut d’Etudes Politiques and UC Berkeley, where she was awarded her doctoral degree in 1990.  After eight years as a faculty member, she transitioned to a career in fundraising, working with major national foundations, and eventually leading UC Irvine’s fundraising efforts for scientific research.  After retiring from UC Irvine in 2013, she  took on a leadership role in USC’s campaign for the Dornsife College of Letters, Arts and Sciences.  More recently, she restructured and led programs in foundation relations and principal giving at the California Institute of Technology, helping their program surpass the $1.5 billion mark in their $2 billion BreakThrough campaign.  In February 2018, she launched an independent consulting practice focused on research development and social impact investing. On a pro bono basis, she is working with Claremont Lincoln University and a small group of donors to develop an online course on mindfulness and empathy for use by teachers and nonprofit managers.

As a fan of all things avant-garde and provocative, Marjorie is a past board member of the Long Beach Opera, and regularly attends the Ojai Festival, the Monday Evening Concerts, and Piano Spheres, among other new music events in Los Angeles.  A long-time student of yoga, she teaches (and continues to study) Vedic chanting, and also enjoys gourmet cooking, wine, hiking and international travel.  She lives in the Hollywood Hills with her husband Bill, an awesome garden and two very sociable cats, and spends much of her spare time at Disney Hall enjoying performances of contemporary music, opera and jazz, as well as the classic symphonic repertoire.
