Since its formation in May 2010, RELENTLESS has donated  more than eighty five thousand dollars to organizations focused on cancer research and improving the quality of life for cancer patients. Although RELENTLESS is an organization based in New Jersey, supporters reside in other states including Connecticut, New York, and North Carolina. We are proud to say that we have been able to make donations to local organizations with the money raised.  All of our staff are volunteers which allows us to maximize contributions with minimal administrative overhead. RELENTLESS supports early testing, clinical trials, and research for all types of cancers.
