After graduating from Towson, Bagnall worked as an arts educator at the Holton-Arms School.^[1] She also worked as a playwright and staff member for the Disney Cruise Line.^[3] In 2011, Bagnall founded Tasty Monster Productions with her partner, Luke Tudball,^[2] whom she had met while overseas.^[4]

In February 2018, Bagnall announced that she would run for the Maryland Senate in District 33, challenging incumbent state senator Edward R. Reilly.^[5] She later withdrew her candidacy and instead ran for the Maryland House of Delegates.^[6] Bagnall won the general election in an upset^[7] on November 6, 2018, placing third and edging out incumbent state delegate Tony McConkey by a margin of 185 votes.

In June 2018, following the Capital Gazette shooting, Bagnall's brother, Jason, became distraught and began ranting about communism, conspiracy theories, and mass shootings. Heather tried to de-escalate the situation when she saw Jason sitting on the edge of his bathtub with a sawed-off shotgun, telling her to leave. She left the house and met up with her father at a nearby shopping center from where they called 9-1-1. Heather later filed for a protective order against Jason, who was charged with second-degree assault in connection with the incident.^[11] During Jason's trial in April 2019, Heather testified that he had threatened her, but not with a gun pointed at her as the police report alleged, and said that the family hoped to get Jason help with what they believed was an undiagnosed mental health condition. The sentencing phase of Jason's trial ended in a hung jury, prompting the judge to declare a mistrial.^[8]
