Meet Your Local Long Island Realtor

Hi, I'm Seth Hanneken.


I’m a Long Island real estate agent, educator, and proud dog dad behind Homes by Hanneken. My goal is simple: help people make smart real estate decisions while making the process enjoyable and stress-free.


Whether you're searching for your dream home or preparing to sell, I bring local market knowledge, strong negotiation skills, and a modern marketing approach to every client I work with.
