Albert J. Krupski, Jr. is a farmer, lifelong North Fork resident, and one of the most experienced public servants in Southold history. Born and raised on the North Fork, Al attended the University of Delaware, where he earned a B.S. in Plant Science. He and his wife Mary own and operate Krupski Farms in Peconic, where the family has been growing pumpkins, tomatoes, sweet corn, watermelons, and a wide variety of seasonal vegetables for five generations. They have three children and eight grandchildren.

Al's career in public service spans four decades. At age 26, he was elected to the Southold Town Board of Trustees in 1985 and served there for 20 years, the last 14 as Trustee President. During that time he spearheaded a rewrite of the town's 30-year-old Wetland Code, which modernized environmental and legal protections for Southold's shoreline. After two decades as a Trustee, he was elected to the Town Board in 2005. There he co-wrote a townwide drainage code to reduce road runoff into creeks and estuaries, championed legislation to protect local businesses by keeping big box stores out of Southold, and was closely involved in developing the town's first Wind Energy Code. He played a key role in the enactment of Southold's landmark Dark Sky Law — one of Long Island's first protections against light pollution. He also led the push to protect Plum Island — using Southold's local zoning authority to block commercial development of the island in the event of a federal sale — and later helped secure a congressional ban on the island's commercial sale while serving in the County Legislature.

In 2013, Al was elected to the Suffolk County Legislature representing the First Legislative District — only the second Democrat ever to hold that seat — where he served for 11 years. He was also the first farmer ever to serve in the legislature. His decade in county government focused on land preservation, water quality, public safety, and the long-term vitality of the East End.

Al was elected Town Supervisor in November 2023 and took office in January 2024. He brings to the role an unmatched depth of knowledge of Southold's government, environment, and community — and an abiding commitment to preserving the rural character and quality of life that make Southold extraordinary.
