Your tax-deductible donation will help us continue our work of funding stomach cancer research and making our world a better place!  Together, we can improve our society and make our world cancer free.  Thank you for your generous support!

Where Donation Dollars Go


All of our directors, officers, and employees volunteer their time and do not take compensation for their work.  That means we can maximize our impact, and put the contributions we receive where they work and where they make a difference. We are making a tangible difference in the world.

Our first funding project was in 2015 with Saint Louis University.  With the establishment of The Project Periwinkle Gastric Cancer Research Fund at Saint Louis University, both Project Periwinkle and Saint Louis University Cancer Center are working toward research for stomach cancer.  Our second contribution was made in February 2018 to the Fred & Pamela Buffett Cancer Center at the University of Nebraska Medical Center in Omaha.  We are helping to support the Gastrointestinal Research Program at UNMC. Most recently, on January 12, 2019, we gave to the University of Texas, MD Anderson Cancer Center in Houston supporting their Gastric Cancer Research Program.

With the work that is being done, we are working toward our mission of funding stomach cancer with the goal of finding a cure.  So much more is needed to be done, but we are excited for what the future holds.
