About Jay Costantino

Jay Costantino Hanover, MA Real Estate Agent Headshot

Agent Details

Meet Jay

With over a decade of experience serving the South Shore and surrounding communities, I am committed to delivering exceptional real estate results. I was honored to be named to the 2025 Jack Conway Silver Club, placing me among the top 10% of agents company-wide.
 
I began my real estate career in 2015 and earned my broker’s license in 2020—an accomplishment held by less than a quarter of Massachusetts agents. As a broker and proud member of the National Association of REALTORS®, I uphold the highest standards of professionalism, training, and ethics.
 
My mission is simple: to provide every buyer and seller with outstanding service, clear communication, honest guidance, and high-quality marketing.
 
Outside of real estate, I stay active in the South Shore community through coaching baseball. In 2025, I became the Varsity Baseball Head Coach at Silver Lake Regional High School and also ran summer clinics to help young athletes develop their skills.
