As a student at Boston College, Mary had two opportunities to visit Japan. During her trips, she conducted independent research on Hiroshima, interviewed 25 people familiar with nuclear issues, interned at the World Friendship Center, participated in the World Conference Against A & H Bombs, and helped organize the YMCA’s International Youth Peace Seminar. Returning to Boston profoundly influenced, Mary began volunteering with organizations like the American Friends Service Committee and Global Zero. In 2015, she participated in the Japan Council Against A & H Bomb’s annual Peace March as an international youth relay marcher, walking from Okayama to Hiroshima to spread awareness of the dangers of nuclear weapons. Her dream was to move to Hiroshima, and after hearing about PCV she was determined to live there.
