For 17 years, Brennan has been dedicated to helping serve the Rotary District 6510's Belizean Children's Program. She travels to Belize once a year with physicians to identify children who will come to the United States for orthopedic surgery. She photographs patients, coordinates their travel, and recruits host families to care for them. While they are in the U.S., she coordinates their medical care, testing, and physical therapy until they are ready to return home to their families in Belize.
