The Lee & Aidan McMahon Foundation was founded by the McMahon brothers, Michael, Joseph and Thomas, in loving memory of their mother Lee McMahon, who passed away from brain cancer in 1999 and Aidan McMahon, beloved son of Joseph, who passed away in 2002 at 13 months of age from biliary atresia, and complications from liver disease. The McMahon brothers, with the help and support of many family and friends, have held the charity golf outing each year for the past 20 years. The event has grown each year with over 250 guests participating. We also have been very fortunate to have many sports celebrities attend the event year after year to lend their support.
