Dempster Family Foundation’s “Casino Night” July 13, 2011 Ryan Dempster is a starting pitcher for the Chicago Cubs and has over thirteen years of MLB experience. He has been with the Cubs for the past eight years! His daughter, Riley, was born in 2009 with the genetic disorder 22q, which prompted him and his wife to start the Dempster Family foundation. The disease is a chromosomal abnormality that causes a very wide range of health issues. Not only does the disease cause developmental issues, but it also is the source of heart defects, autism, and immune system problems. Currently, a cure does not exist and children suffering from the disease require significant medical attention.
