As a member of First Presbyterian Church of Northport, she served as an elder, sang in the Chancel Choir, directed the youth choir, and chaired the building renovation campaign. She served 40 years in the Long Island chapter of Youth for Christ.

Charlene had a beautiful soprano voice and was best known for vamping on “Sam, You Made the Pants Too Long” during Katzenjammer arch sings.
