A licensed real estate professional for more than 20 years, Katie Haggerty possesses an invaluable skill set and impressive track record that is backed by a strategic, client-driven approach. Relocating more than 17 different times over 19 years, Katie and her family have formed countless memories in New York City, The Hamptons, Chicago and Michigan. Through her experiences she has built strong, trustworthy relationships and developed endless market knowledge that she provides to her clients to find their dream home.

Katie truly believes that real estate is not only the best investment financially, but for the lifetime of memories. As she likes to say, “plant your feet and grow.” Planting their feet at each home, Katie and her family were able to blossom and become the best they could in everything they did. Starting her own fashion design collection along the way has given Katie the true meaning of working with all different types of interesting people.

Growing up, Katie was introduced to the world of real estate at a young age. Her father owned his own construction company and her mother practiced real estate tax law. Following her real estate dreams, Katie joined Halstead Real Estate in New York City and The Hamptons. Her acquired knowledge gives her the ability to guide her clients seamlessly through every step of the real estate process.

Her husband Sean and their three children love NYC and live on a boat in Montauk all summer. Her oldest son rows at Georgetown University and her two daughters run in high school. After moving 17 times, their numerous adventures have taught them a lot about real estate and it is something they all have a love for. The family is also a member at New York athletic club on 59th and 7th.

Katie is always ready to meet new people and loves to find the perfect home, rental property, or commercial space for your company.
