"I love Mrs. Dennen, and we've known her since we were kids. I wouldn't have bought our house from anyone else," says Brian and Beverly Hegarty, lifelong residents of Garden City and Mary's first customers when she began selling real estate 10 years ago. This sentiment is echoed throughout the community, where many of her children's friends have grown up and continue to live as adults with their own children. What makes Mary such a standout in the real estate community is her sincere desire to find what is right for each one of her clients, her kind nature and her integrity. A 25 year resident of Garden City, Mary knows the market inside and out, and enjoys sharing her knowledge with her clients. Her 20 years experience in retail sales and management provided a great background for her move into real estate. "Being able to lend my expertise to help my clients evaluate what they might need in a home, or point out some positives or negatives that might not have been visible to them, that is what makes real estate rewarding for me. There's something very special about making the match between a client and their perfect home." Mary loves going to the ballet and spending time with her three grown children and her four grandchildren. When she isn't selling real estate, she likes to dig into a good book or go for a power walk. She lives in Mineola, NY.
