Liver Life Challenge Ambassadors play a critical role in ensuring the success of American Liver Foundation’s (ALF) official endurance program, where dedicated athletes from across the country use their passion and commitment to go the extra mile for the liver community. Liver Life Challenge Ambassadors serve as key volunteers for the endurance program and bring a wealth of knowledge, experience, and passion to the table. Their leadership and dedication help the program grow and ensure that ALF can continue improving lives, increasing awareness, and advancing life-saving treatments and cures.
If you are interested in becoming an ambassador, please email Sarah Miller at firstname.lastname@example.org.
