Meet the Business Owner
Richard L.
Business Owner
I started working with my dad when I was 12 years old at Builders Specialty & Hardware in Somerville, MA. When I was able to drive I got a job at Commonwealth Lock in Cambridge Ma. It was the largest lock shop in New England at the time. I later went to work at Herb’s Lock in Arlington Ma until opening D&D lock in 1980 with my dad. I bought my dad out after he retired in 2001. My son in law Chris has been working with me since 2004 and is line to be the next owner.
