Joseph Michael Sempolinski is an American politician currently serving as a member of the New York State Assembly, representing the 148th district. A member of the Republican and Conservative parties, Sempolinski has a background in both state and federal government. He previously held office as the U.S. representative for New York's 23rd congressional district from 2022 to 2023. His political career has been marked by a commitment to public service and a focus on various legislative issues relevant to his constituents.

Early life and career

Joe Sempolinski was born on February 10, 1983, in Elmira, New York. He grew up in the region and completed his secondary education at Corning-Painted Post West High School, located in Painted Post, New York. Following high school, Sempolinski pursued higher education, earning a Bachelor of Arts degree from Georgetown University, a prestigious institution known for its rigorous academic programs. He furthered his studies at Yale University, where he obtained both a Master of Arts and a Master of Philosophy. This educational background provided him with a solid foundation for a career in public service and politics.

Sempolinski's professional journey began in the political arena when he joined the office of Congressman Tom Reed. From 2010 to 2015, he worked in various capacities within Reed's office, ultimately serving as District Director. This role allowed him to gain valuable experience in legislative processes and constituent services, as he engaged with the community and addressed the needs of the district. His involvement in local politics deepened when he became the Chairman of the Steuben County Republican Committee, further solidifying his connections within the party and the community.

Before his congressional run, Sempolinski served as Chief of Staff for New York State Assemblyman Joseph Giglio. This position provided him with insight into state-level governance and legislative affairs, preparing him for the challenges he would face in his subsequent political endeavors.

Legislative service

In 2022, Sempolinski's political career took a significant turn when he was selected to run for the U.S. House of Representatives in a special election for New York's 23rd congressional district. This opportunity arose after Congressman Tom Reed announced his resignation from the seat, which he had previously indicated he would not contest in the upcoming election cycle. The resignation created a vacancy in the 117th United States Congress, necessitating a special election to fill the position.

The special election was held on August 23, 2022, and Sempolinski emerged as the Republican candidate after being chosen by the Republican county chairmen from the district. His opponents in the Democratic primary included Max Della Pia, who ultimately became the Democratic nominee. In the general election, Sempolinski won by a margin of 53% to 47%, securing victories in ten out of the eleven counties within the district. However, Della Pia achieved significant support in Tompkins County, illustrating the competitive nature of the race.

Sempolinski was sworn into office just before Congress reconvened on September 13, 2022. During his brief tenure in the U.S. House, he was assigned to two key committees: the United States House Committee on the Budget and the United States House Committee on Education and Labor. These assignments reflected his interests and areas of focus within the legislative process.

Despite his election to Congress, Sempolinski pledged not to seek re-election in the November general election. His decision to step back from the congressional race allowed him to concentrate on his future political aspirations at the state level.

In February 2024, Sempolinski announced his candidacy for the New York State Assembly, aiming to represent the 148th district. This move was strategic, as he sought to succeed Assemblyman Joseph Giglio, who had previously employed him as Chief of Staff. Sempolinski successfully defeated his Democratic challenger, Daniel Brown, in the general election held on November 5, 2024. His victory marked a return to state-level politics, where he could continue to influence legislation and serve his constituents.
