Parker is an American campaign specialist who was previously Virginia field director of The LIBRE Initiative, a non-partisan movement that aims to financially empower the Hispanic community in the US.
During her tenure there, Parker spearheaded grassroots outreach campaigns and MRM hopes to tap into these skills with her appointment.
She took up her role this week.
Havard Hughes, head of public affairs at MRM, said: "With the most uncertain general election in a generation looming, we intend to ensure that the division continues to grow to respond to the challenges ahead.
"The financial sector constantly faces major challenges from aggressive regulation and knee-jerk political intervention. There has never been a better time for the financial services sector to engage in public and regulatory affairs to win its arguments in the court of public opinion."
