The Tri-Boro First Aid Squad was founded in January 1938. During the first year of operation, the Squad rendered assistance in 83 emergency calls and 68 silent transportation calls, traveling a total distance of 6,000 miles. The first Squad Building, located on J Street, was completed in 1939. The first ambulance was a ten-year-old Studebaker purchased from the Point Pleasant First Aid Squad. It was first housed in Flitcroft's garage before the J Street building was constructed, with volunteers answering first aid calls in the three towns originally covered by the Squad: Seaside Park, Seaside Heights and Lavallette. Lavallette soon organized its own first aid squad, and Tri-Boro added the Borough of Island Beach to its coverage area. The first patient of the Tri-Boro First Aid Squad was C. Vernon Sparks, who had suffered a heart attack. The ambulance was in Point Pleasant to be painted, yet responded to the call for assistance at record speeds. The Squad assisted Dr. Samuel Tilles in saving Sparks life. In 1940, two more ambulances were acquired, a LaSalle and a second hand Buick. The LaSalle was advertised as "one of the finest in New Jersey, the body custom built, equipped to carry four persons ... with running water and the cot equipped with an airflow mattress." Another Buick was purchased in 1948 and a Cadillac was bought in 1953. Membership in the Tri-Boro First Aid Squad decreased during World War II, when only seven of the 21 members were on hand to serve the three communities. Today, the Squad has more than sixty members. Construction on a new Squad Building began in March 1971 and was dedicated Saturday, December 16, 1972. The Squad continues to update their equipment and replace older vehicles.

Residents of the borough who volunteer their time as members of the Tri-Boro First Aid Squad are notified of an emergency by a pager and by a siren. Please be alert for members responding to the first aid squad building at J Street; yield to personal vehicles with blue lights or hazard lights flashing.

As a volunteer organization, the squad relies heavily on residents for support. To join the first aid squad, first aid squad auxiliary, or to make a financial donation, please contact the first aid squad. The Tri-Boro First Aid Squad provides emergency services to Seaside Park, the South Seaside Park section of Berkeley Township, and Seaside Heights.
