Dana L. Dornsife: Founder and Board Chair

Dana Dornsife founded Lazarex Cancer Foundation, a nationwide non-profit organization, in 2006 in response to a family experience with cancer.

In 2016, Dana expanded the mission at Lazarex to bring sustainable and transformational change to the bench to bedside process of clinical trial enrollment, retention, minority participation and equitable access with IMPACT (IMproving Patient Access to Cancer Clinical Trials). Most recently, Lazarex created collaboration around a public health initiative in Philadelphia, PA – Community IMPACT. This bold initiative is aimed at creating a replicable model to improve cancer health outcomes and associated co-morbidities for the residents of medically underserved and socioeconomically challenged minority neighborhoods throughout major metropolitan cities and beyond.

Dana is a graduate of Drexel University in Philadelphia. She is a board member of the USC Brain and Creativity Institute at University of Southern California, serves on the UCSF Cancer Leadership Council, and the MGH Presidents Council.

With the mission to raise funds to help cancer patients access and pay for treatments, they used their endurance sports platform to help others. The team made an instant splash at events due to the very “loud” race kits that they wore, which drew instant attention with its hot pink and lightning bolts design. From that point on, the Team Cancer Sucks following grew.

To date, Team Cancer Sucks has raised over $200,000 for cancer awareness and treatment.
