"Mark made the selling of our home a painless experience in his professional, organized, knowledgeable manner. His suggestions for making it more marketable were brilliant; and he always acted in our best interest, both in the sale of our home and the consequent purchase of a condo. We were very glad to have chosen him as our realtor."

-Marie and Gary, Babylon Village

"His expertise and advice on selling our home was fabulous! He takes pride in doing what is in the best interest of his client and is quite knowlegable about the real estate market. He is a very caring and a very professional agent. We would highly recommend him!"

-Denise, Centereach

"I would absolutely recommend Mark Donnelly for his aptitude of this ever changing real-estate market, as well as his comprehensive follow-ups and attention to details. Mark's endless energy and drive to facilitate our real-estate needs makes him a star in this business."

-Angela, Sayville

"Our home is fairly new to the market and Mark has made great efforts to present it in creative ways. He had a professional photographer come to our home and take pictures for a beautiful brochure, postcards, and flyers. He even contacted brokers in Europe in an effort to reach a possible market there.  He is very professional and a pleasure to work with."

-Jean, Brookhaven

"Mark Donnelly became my agent after a previous contract expired with another real estate company. They failed to sell my house even though it was priced lower and they had it for six months. Mark came in promptly, took beautiful pictures of the house, inside and out. Within one month we had a buyer!! My husband and I were very pleased with the outcome. We got the price we wanted. Mark is a very professional, courteous, kind, understanding real estate agent. He always responded to our questions and kept us abreast of all correspondence involving the sale of our family home. I would and have several times recommend Mark Donnelly to all our friends and family."

-Joanie, West Babylon

"In these challenging times for selling homes, I listed my home through Mark and it sold within weeks! What more need I say?"

-Destine, Northport
