The Parkway community owes great thanks to Mark for founding the Parkway Alumni Association in 1991. He and several North '76 classmates planned out the organization after their 15-year reunion. Mark envisioned an association that was more than just a social organization, but one that gave back to the Parkway community. The association's mission statement epitomizes Mark's commitment to giving back to the community, "To encourage communication among alumni and to foster programs which serve and support the Parkway community." Mark served as the first association president and now serves on the honorary board. He received the Superintendent's Award in 1994 for his volunteer work for the betterment of the district.
