Bulldog has always been about the people. The people we protect, our valued employees and our trusted partners.

A Boston native and avid Patriots fan, Melissa is the newest member to our Bulldog management team.  Though new to the security sector, Melissa has spent the last 14 years in sales and marketing and put simply- she’s as customer-centric as they get.
