Meet the Team
Tammy McKenna
Events Manager
Tammy is the embodiment of the mansion and she has truly earned her nickname of "The Commandress." Her entrepreneurial journey started in her early twenties when she opened her own nail salon in Newton. After a few years, she was introduced to the events industry and worked in custom event linens. It was on one of her event installations that she fell in love with the Commander's Mansion. Years later, she even got married here!
​
Tammy has been at the helm of the Commander's Mansion since 2005. She will manage your event from beginning to end with the utmost kindness and professionalism. She is a mom and Abuelita ("Aba"), who loves spending time with her family and traveling.
