Seth Koslow is not a typical politician.
He’s a lifelong Nassau County resident, dad, coach and former prosecutor.
Born and raised in Baldwin, Seth grew up watching his father achieve the Nassau County Dream, starting a small CPA business from their home and growing it into a thriving practice that helped provide Seth and his siblings with the opportunity to attend college and build their own futures.
Now, Seth is running for Nassau County Executive because taxes are too high, the county wastes too much money, and regular folks are paying the price.
A father, husband, coach, former prosecutor, small business owner, and Nassau County Legislator, Seth has spent his career standing up for fairness, fiscal responsibility, and safe communities.
After earning his undergraduate degree from American University and his law degree from Touro Law Center, he was admitted to the New York State Bar. Seth Koslow served as an Assistant District Attorney in Queens County before opening his own practice, SIK Law, where he continues to fight for justice.
His experience as both a prosecutor and a legislator has shaped his commitment to transparency, accountability, and putting people over politics.
He understands the real struggles Nassau County families face—from skyrocketing property taxes and crumbling infrastructure to wasteful spending and government mismanagement.
Seth is ready to restore trust, eliminate inefficiency, and build a county that works for everyone.
Seth lives in South Merrick with his wife, Jill, their three children and rescue dog Coco.
He’s running because he wants to ensure that his children, your children, and future generations have a fair shot at the American Dream—and he’s ready to lead Nassau County toward a brighter, stronger future.
It’s time for a change Nassau, because we deserve better!
This election is about more than politics; it’s about building a Nassau County that works for everyone.
Together, we can restore trust in government, end wasteful spending, and create a future where families and businesses thrive.
