About Diane
Diane's extensive background dealing with people makes her extremely caring, passionate, detail-oriented, and understanding of each individual's unique needs. As a former dental hygienist in Smithtown and Babylon for many years, she enjoyed working with lots of different personalities, taking the time to educate patients and build strong relationships.
As a dedicated residential sales agent, Diane provides the same stellar service to her clients seeking to buy and sell homes in her local market. She goes above and beyond to ensure a smooth, pleasant experience, which is enhanced by her warm nature, honest advice, and trustworthy approach that always includes open communication.
Her hard work ethic, hands-on guidance, and keen problem-solving skills further distinguish Diane as a capable, results-driven professional. She specializes in purchases and sales in all areas of Long Island, and has a particular fondness for working with first-time homebuyers to help them achieve their dreams.
Originally from Queens, NY and raised in Ronkonkoma, Diane received a degree from SUNY Farmingdale as a Registered Dental Hygienist. She holds her New York Real Estate Salesperson License, as well as NYSAR, Long Island Board of Realtors, and National Association of Realtors designations.
Having lived and worked in Smithtown for 25+ years, and a boater on the South Shore her entire life, Diane brings exceptional expertise to the real estate process. She genuinely loves to find clients a home and neighborhood they can comfortably settle in, and get the best price for sellers seeking to part with their prized asset. Utilizing a team of expert service providers, she makes the process seamless with access to stagers, painters, designers, handymen, inspectors and others.
Married with two college-age daughters, Diane was very involved with the school district and loves her community. Her favorite hobbies besides spending time with family include boating, traveling, working out, beach volleyball, entertaining, and trying new restaurants.

What clients say
“Working with Exit Realty, Diane Mascellsro and Ed Pearson was exceptional from start to finish. Selling a home can feel overwhelming, but they made the entire process smooth, organized, and even enjoyable. I gave them full reins to handle the showing, marketing, and pricing, they explained every step clearly, always making sure I felt confident. Communication was outstanding, I was never out of the loop. Their marketing strategy was impressive, making my home look incredible and generating immediate interest. They even secured a sale price above my expectations. Living in Las Vegas while selling a home in NY could have been stressful, but I never had to travel once. Truly amazing. I highly recommend them and would absolutely work with them again. Thank you, Glenn.”
