Proudly Serving Our Community for Thirteen Generations


Who We Are


President; LICENsEd agent

Joshua J. Borsack

Joshua is the 3rd generation of his family to serve as President of Strong Insurance Agency founded by his grandfather James M. Strong IV.  He is proud to carry on his family's practice of protecting the East End of Long Island; a tradition that dates back to James G. Scott, the longest serving head keeper at Montauk Lighthouse, serving from 1885 to 1910.  The land where Strong Insurance Agency sits was once home to the Strong Brothers Blacksmith Shop, whose founder once served as a Town Trustee, working for the preservation and fair use of the lands that make up the Town of East Hampton.  Joshua takes great pride in helping businesses, individuals and families create personalized insurance solutions that will protect and preserve their future.  When Joshua is not in the office he is spending time with his wife, Summer and their 3 young children working in his garden and enjoying the beautiful beaches and trails that this community has to offer.  Joshua is a member of the East Hampton Rotary and serves as an Elder and a member of the Mission Committee for the First Presbyterian Church of East Hampton.

Summer L. Borsack

Summer began her career in the insurance industry with a national insurance carrier working in their commercial division.  Over time she found that working more closely with individuals was her passion, and made the move to an independent insurance agency.  In 2014 Summer came to Strong Insurance Agency where her past experience at both the corporate level and local, client side level has proved to be invaluable.  Summer is a strong advocate for her clients, working with them and the carriers to ensure that all of their needs are met, their assets are protected and their costs are minimized.  When Summer is not in the office she is spending time with Joshua and their 3 young children.  She serves as the Moderator of the Board of Deacons at First Presbyterian Church in East Hampton, volunteers for the Maureen's Haven Homeless Program, East Hampton Rotary Club and the Trails Committee of the East Hampton Ladies Village Improvement Society.

Kathleen S. Skellington

In 2015, Strong Insurance Agency was pleased to welcome Katie as a Customer Service Representative and since that time she has gone on to become a fully licensed New York State Insurance Agent.   As the granddaughter of our founder she, like Joshua and Summer, carries an appreciation of upholding her family's long established tradition of serving the East End of Long Island and working with customers to help find insurance solutions to best protect their hard-earned assets. Her experience in both retail and administrative work has created a foundation of solid communication and personal attention to the individual needs of each customer, which she continues to build. When not in the office Katie enjoys spending time with her husband of ten years Gary, a teacher and head of the Mathematics department at Ross School in East Hampton.
