Thomas Addison Obituary

Published by Legacy Remembers on May 4, 2025.
Thomas Addison passed away peacefully on April 27, 2025, in Port Jefferson, New York, with his family by his side.

Born on February 28, 1955, Thomas was the son of the late Doris L. (Addison) Sokol and George H. Addison. A lifelong Long Island resident, he cherished life near the water and found joy in golf, racquetball, and spending relaxing days at the vineyards with those close to him.

Tom shared a devoted partnership with June Pelzer for over 40 years-a bond marked by love and unwavering companionship. His professional life reflected his passion for entrepreneurship and finance. Known for his intelligence, wit, and kindness, Thomas built lasting relationships with clients, coworkers, and friends who will deeply miss his presence.

He is lovingly remembered by his partner June Pelzer; sister Judi (Addison) Kostek and her partner Jon; sister Kathy (Sokol) Lepanto and her husband Gene; niece Kaitlin (Kostek) LaPine and her husband Josh; great-nephew Leo; sons Cliff Pelzer and his wife Andrea, and Robert Pelzer; as well as grandchildren Kyle, Colin, Zachary, and Skyler.

A memorial service will be held at a later date.

Thomas's legacy lives on in the memories of those who knew him best-through laughter shared, wisdom offered, and moments treasured.
