In 1966, The Reverend George W. Busler was called as the third rector and under his leadership youth ministry flourished, the Beinicke Building was constructed to house a family counseling program, stained glass windows were installed in the nave, and the columbarium was built.
In 2001, The Reverend Christopher David was called as the fourth rector. In order to meet the needs of a growing community and parish, the congregation embarked on a major building campaign to construct a parish hall for church and community use, to expand the educational facilities, and to enhance parish office space.
As the community continued to grow, young parents expressed a compelling need for a nursery school in town. In 2004, Bright Beginnings was created as a New York certified parish day school with a full time director.
In 2012, The Reverend Mark Powell was called as the fifth rector. Saint Mark’s has a long history of commitment to young people through Christian formation and pre-school education. Father Powell continued that commitment, revitalized stewardship, and sought to explore avenues for mission and outreach. Fr Powell's tenure at St Mark's was short as he left to pursue a different career.
St Marks called their sixth and current Rector, Father Michael Ralph. Fr Ralph and his wife Aimee have brought a renewed energy to St Mark's. The Ralph family left St Mark's in July 2019 to continue ministry at St. Luke's Granville, Ohio
