Pam Mowry
Executive Director

Pam Mowry has more than nineteen years of nonprofit management experience, primarily in the areas of fundraising, board development and event management. Mowry’s career began at the Oklahoma Arts Institute at Quartz Mountain in 1998. In 2005, she joined the staff of Lyric Theatre of Oklahoma just as their capital campaign was getting underway to renovate and endow three properties on NW 16th Street in Oklahoma City, known as the Plaza District. Lyric was successful in reaching its goal to double their artistic programming and expand their community outreach when the historic Plaza Theatre opened in December 2007. Mowry left Lyric in 2012 to become the Executive Director of Oklahoma AIDS Care Fund, and coordinated three Red Tie Night events before joining the Boys & Girls Clubs of Oklahoma County staff.

During her career, Mowry has served as Chairman of the 2012 Oklahoma Arts Conference in Oklahoma City and served on the Oklahoma State University College of Arts & Sciences Alumni Board. Mowry has served as a guest speaker and panelist on various fundraising topics, including capital campaigns, corporate sponsorships, and creative fundraising ideas.

Pam Mowry earned a Bachelor of Music with Elected Studies in Business degree from Oklahoma State University. During her time at OSU, she had the honor and privilege of studying choral music with Dr. Jerry McCoy. Performing in Concert Chorale, the group toured Europe and performed at numerous American Choral Director’s Association Leadership Conferences across the United States. “It was one of the best times in my life,” said Mowry, “performing choral music is a spiritually uplifting experience, and I enjoy it immensely.” Mowry has also sung with Stillwater Chamber Singers and Windsong ensembles.

Pam and her husband Mike have two daughters who attend Oklahoma State University and Edmond Memorial High School. In her spare time, Pam serves as Vice President of Edmond’s Bulldog Band Boosters.
