About Me

About Katie Milligan

Katie Milligan was born in Illinois, raised in California, then moved to the Washington D.C. area before attending Southampton College in 1975. It was here that she met her husband and decided to put down her roots, purchasing her first home in the Village of Southampton in 1981. For over 35 years the couple operated their own successful business, Milligan Seafood, which distributed seafood locally and abroad. During this time, Katie also gained personal experience on both sides of the table as a property buyer and seller. She still owns and manages several rental/investment properties, having purchased, renovated and sold several properties over the years. Her sharp business sense, deep community roots and seasoned market knowledge ultimately proved to be invaluable when she decided to enter the real estate business as a broker. With her children grown and the seafood business sold, Katie decided to devote her time, energy and fresh outlook to her passion: real estate.

Words from our clients

"Katie is just terrific! Not only sold my house during the worst time in the market but helped me helped me purchase a short sale during that same time and held my hand throughout! She's not only one of the really good ones, she's one of the nicest!!

Betsy Mansfield

“It would be hard to adequately convey my gratitude to you for everything you have done to make my house sale flawless and seamless, and a real pleasure. You are the best, Kate and it has been very lovely working with you….”
