Join us, June 7th, for a very special First Sunday Gospel event, with Maria Marable-Bunch, former Associate Director of Museum Learning and Programs at the Smithsonian Institution and recipient of the O Museum Mrs. Rosa Parks Humanitarian Award.

Ms. Marable-Bunch will discuss the lessons learned during her career grounded in the values instilled by her parents as a child growing up in Alabama and Pennsylvania. Her journey reflects the power of integrity, perseverance, and service — lessons that shaped her path as a leader in museums and education.
