Team

After years of hearing the frustration of his cancer patients, Dr. Sender gathered a team to find a solution.  The SeventyK team came together at the University of California, Irvine in 2008 to write the Adolescent and Young Adult Cancer Bill of Rights with the help of many survivors, caregivers and healthcare professionals.
