Marion co-chairs the State Street UK Pride Network, where she acts as a role model for gay women. She regularly appears on panels to discuss the specific issues faced by LGBT+ women and she organizes events with a strong focus on women. In the last two years, Marion has organized two book launches at State Street, one dedicated to the lives of older lesbian and bisexual women, and the other dedicated to the former Press Officer to two Prime Ministers who shared her views on gender equality and the LGBT+ community. Marion always looks to increase diversity when hiring new talent and reminds the management team of this imperative. Within Interbank, where she was the second female co-chair, Marion continues to work tirelessly to increase the representation and visibility of women.
