Our Story

Florence Lock & Key founder Mark Sienkiewicz is the definition of “Hometown.” Born and raised in Florence, the 1981 Northampton High School graduate has spent his life serving and enjoying the community in which he lives. From teenage jobs at Friendly’s and Caldor to running the family business, Florence Hardware, with his brother Todd, Mark has been involved with local commerce on many levels.

In 1992 Mark founded Florence Lock & Key, spending those early days working out of the back of his Chevy Cavalier. Before long, the Cavalier was replaced with the distinctive Florence Lock & Key van, of which the 4th generation can be seen cruising all over the Pioneer Valley. In the fall of 1993 Mark made his best business decision to date, marrying his wife Jackie, well-known to loyal customers as “The Voice” of Florence Lock & Key. Ever since, Jackie has maintained customer service and administrative duties for the company, in addition to caring for the couple’s two kids, Sarah and Michael!

On top of running a successful business, Mark was an integral and active member of Easthampton’s volunteer Community Emergency Response Team for over nine years. For severals years as “CERT’s” Commander, he routinely worked with local and state police in times of need, leading his team during search and rescue operations, natural disasters and other local emergencies.

When he’s not working, Mark can be found supporting Sarah and Michael through their many activities at Easthampton High School, cheering for the Red Sox, Patriots and UMass, or following his nephew's lacrosse careers.

Mark is proud to live and work in the Pioneer Valley, and looks forward to doing business with you!
