About Us

Three generations of personal service since 1953.

John J. Glennon opened an Independent Insurance Agency more than 50 years ago with a simple objective: offer people the right insurance at the right price. His hands-on, personal commitment to his clients was met with immediate success. He established long standing client and company relationships that still exist today. His was the agency of choice for individuals seeking auto and home coverage as well as institutions ranging from hospitals, an art gallery and advertising agency.

In 1965, his son John E. Glennon joined the firm and quickly expanded the agency to include Life and Health Insurance. John made an immediate impact with his accounting background and soon after achieving a Chartered Life Underwriter designation and law degree from St. Johns University. His innovative, can-do approach allowed the Glennon Agency to offer an even greater range and breadth of insurance options for their clients.

Outside of the office, John is always someone to give back to the community, he volunteers with his Little League. Since 1980, he has served on the Little League board as Director and Senior Member. During baseball season, look for John at local games. If he’s not in the stands, he’s out on the field umpiring.

John J., the third generation Glennon to join the firm, brought even greater efficiency and even more rapid customer service to Glennon clients with updated technology that ensures Glennon clients the best in personalized service. In 1998, he graduated from the University of Hartford and shortly after received his property and casualty insurance license. John has focused his career working with personal and business insurance customers.

Born and raised on Long Island, John enjoys spending his free time with his family, traveling, running, biking and boating on the Sound. John and his growing family live in Suffolk County.
