Micaela Healy was born in Bedford, New Hampshire to Michele Johnson and Steven Healy, being the first of two children. While she'd been on stage since the age of 2, her passion for acting didn't fully manifest until 10 years later when she began participating in local drama organizations. Micaela graduated from high school in 2015 as a member of the International Thespian Society and the recipient of the Excellence in English Award presented to the top English student of the senior class. She would, a few months later, be nominated as Best Supporting Actress in a Youth Production for the role of Hedy in "How to Succeed in Business Without Really Trying" in the 2015 New Hampshire Theatre Awards. While the bulk of her work is on stage, she has also appeared in a several web series. While pursuing her bachelor's degree in political science at Marymount University (2015-2019), she continues to act on stage and in film.
