He is a member of three other map societies. Steve has developed educational programs for Nursery School and Elementary School students, utilizing maps to explore science, history, geology, geography, humor, art and many other disciplines. Steve is also involved with other not-for-profit organizations: for 26 years he was a Trustee and volunteer with The Educational Alliance, a 125-year-old multi-generational community service organization with over 15 facilities on the Lower East Side and East Village, serving over 50,000 New Yorkers every year; he remains an Honorary Trustee.

In 2010 Andrew Kapochunas retired from decades as a consumer and business data/processing consultant — including at Dun & Bradstreet, where he was awarded patents for domestic and global address maintenance. Prior to that, after graduating from Stuyvesant High School and the City College of New York with a degree in Biological Illustration, he spent 13 years in publishing, becoming Editor-in-Chief and Associate Publisher of multiple magazines. In 1988 he began collecting antique maps of the area of the Polish-Lithuanian Commonwealth, and in 2008 built his site https://www.lithuanianmaps.com/, which, went it went static in 2021 (because its platform ceased to be updatable) had 4,330 high-definition downloadable images. The images and text on that still active site were transferred in 2024 to one hosted by the Lithuanian Cartographic Society: https://lietuvoskartografija.lt/lithuanianmaps/, with financial support from Lithuania’s Ministry of Foreign Affairs, which considers it a national resource. He became Secretary of the New York Map Society in 2014 and soon began partnering with Steve Hanon and Laura Ten Eyck in society membership and program development. He began giving map-related presentations in 2013 at venues such as Seton Hall University and the New York Public Library, and to in-person and Zoom audiences ranging from map society members, genealogical groups, and UN ambassadors interested in the historical relationship of their countries to Lithuania.
