Sidney Douglas “Sid” Beebe Jr.
Sidney Douglas Beebe Jr. was born April 11, 1961, in Greenport to parents Constance and Sidney Beebe. On Aug. 23rd, 2025, Sid died peacefully at his home in Mattituck.
Known to many as “Sid” and to his family as “Sonny,” he graduated from Mattituck High School in the class of 1979 and from Cortland State University in the class of 1987. Sid was a fourth generation builder on the North Fork and co-owned Sid Beebe Builders & Sons with his brother, Tom, for 35 years.
Sid held many titles in life: son, brother, boss, coach, but his most important title was Dad. Anyone who ever bumped into Sid knew he was gifted at chatting, and his favorite subjects were his kids, and their many accomplishments! Doug and Alex have become accustomed to strangers congratulating them on lacrosse wins, college graduations and new jobs over the years.
Sid and his fiancee, Marilyn, were always hosting their kids, grandkids and families at the home they lovingly designed and built together. The couple loved traveling with their friends abroad, but visiting Florida for Yankee’s Spring Training every year was always a favorite destination. Sid was an avid fan of Riverhead Raceway and NASCAR, a passion instilled in him from childhood when his parents would load him and his three siblings into the car and travel to racetracks every weekend.
As a life-long animal lover, Sid always adored his dogs, a love he passed on to his kids. Sid and Marilyn’s beloved dogs, Bently and Chase, will miss being absolutely spoiled by Sid.
