Sal Lupoli is sold on the future of the Merrimack Valley real estate market. The founder of the Sal’s Pizza and Salvatore’s restaurant chains has cooked up a second career as a real estate developer, restoring the massive Riverwalk mill complex in Lawrence into a multitenant office and medical complex.

After graduating from Chelmsford High School in 1984, Sal Lupoli went on to become a successful entrepreneur with 40 Sal’s Pizza shops and close to 500 people in his employ. But what Lupoli is most proud of is his ability to give back to Chelmsford.
