Under his leadership, the ACS has become the world’s largest voluntary health organization fighting cancer.

He also helped to create the National Center for Tobacco-Free Kids (now the Campaign for Tobacco-Free Kids), among his collaborations and affiliations.

In 1999, Seffrin was selected to be a charter member of C-Change (formerly known as the National Dialogue on Cancer) Steering Committee, which was co-chaired by former President George H.W. Bush and former First Lady Barbara Bush. 

In 1997, he was appointed to the National Cancer Policy Board of the Institute of Medicine, and in 1999, was appointed by Senator Dianne Feinstein to co-chair the National Cancer Legislation Advisory Committee.
