Welcoming New Faculty, Staff, and Trustees

As the 2020–2021 school year began, St. Mark’s welcomed 18 new faculty and staff members to campus. From the Counseling Office to the drama studio, these new members of the St. Mark’s family bolster existing programs with extensive experience and fresh perspectives. While the year began remotely, these new community members dove headfirst into their virtual classes and remote duties.
“I’m so excited to join everyone here at St. Mark’s,” said Dr. Mary Bonsu, the new Upper School Counselor. “It’s so awesome to be a part of St. Mark’s program incorporating the boys’ mental health, wellness, and well-being into the full picture of educational life.”
Several of the new hires represent an expansion of programs across campus including a new Middle School Drama Teacher, a Lower School Computer Science Teacher, an Upper School counselor, and two Associate Directors of College Counseling. Learn more about our newest faculty and staff members here.

While these individuals are new to the Board, they are familiar faces in the St. Mark’s community, including several alumni and current parents.
