Antonellis Construction, Inc.

Forty years in business and one employee: Antonellis Construction is essentially Loreto Antonellis, the Newton general contractor who started the company in 1986 and incorporated it the following year. The Better Business Bureau lists him as its owner and sole principal, and grades the company A+. Its Massachusetts home improvement contractor registration, #209802, is active on the state registry. The Massachusetts Supplier Diversity Office also certifies the company as both a Minority Business Enterprise and a Disadvantaged Business Enterprise under certification 19920263, both verified active; the minority-business certification expires 2026-12-14. With a single employee, a homeowner deals with the principal directly rather than a project manager.
