Our Ambassadors represent BCMFF and advocate for our cause across a multitude of platforms.

They participate in public events, interviews and conferences. And also, importantly, connect and meet with potential donors. All with the purpose of advocating for a cure for BCM and spreading knowledge and awareness of the disease.

Our Ambassadors help to drive the future of BCMFF and facilitate the support of public or private fundraising activities (such as sporting competitions, charity dinners, auctions and international conferences).

If you want to organize a fundraising or advocacy event in your area or if you want to become a BCMFF Ambassador, please contact our Chairman:,

Mark Young

Mark is retired and lives in Atlanta, Georgia. He and his grandson have BCM, as well as several of his
uncles and cousins. BCM has had a major impact on his family so a cure would be a life-changing event for
many in his family. Mark and his wife Diane especially want to be helpful in finding a treatment or cure
for their 4-year-old grandson Zachary.

Mark graduated from the University of Georgia in 1979 with a major in Accounting and became a C.P.A.
(Certified Public Accountant). After 10 years in public accounting with Deloitte, Haskins, & Sells, Mark worked in senior finance positions as Controller, Treasurer, or Chief Financial Officer for five large public companies. After 10 years as Treasurer of Equifax, Mark retired in 2016.

Mark’s primary goal is to raise awareness and funding for a BCM cure or treatment so that the lives and
futures of young men and boys with BCM will be significantly changed for the better.
