Meet the PAK Board

PAK's mission would not be possible without its team of dedicated and hardworking members and volunteers.


Mary Postma


Mary Postma, an avid advocate and whole-hearted supporter of the performing arts, founded PAK in 2013 as a way to give children access to the shows and performances that have brought her so much joy over the years. Before PAK, Mary was a successful Realtor in Northern Virginia, earning her spot in the Lifetime Multimillion Dollar Club. She is also a beloved wife, mother, sister, and friend.


Claire Machosky

Claire Machosky, an educator by profession, knows the importance of integrating the arts into all cirriculum. Claire's career included being a Social Studies Teacher, Department Chairperson, School Dean, and Educational Consultant. Currently, she is affiliated with the Library of Congress's Teaching and Primary Sources program. A wife, mother, and grandmother, Claire and her husband, Al, reside in Haymarket, VA.

Music and arts have always been Nadine Bishop's passion. As a former music and piano teacher, the joy of observing students as they watched a musical performance at the Hylton Performing Arts Center was all that it took for Nadine to become a member and life supporter of PAK.
