The Madden Open Hearts Camp (M.O.H.C.) is a non-profit,
residential summer camp for children and teenagers, ages 8-16, who have undergone and recovered from open heart surgery or a heart transplant. M.O.H.C. has been fully accredited by the American Camp Association (ACA) since 2003. The Maddens knew the challenges involved, especially for children, in pacing themselves during exercise and play after heart surgery. Thankful for the renewed health that Mr. Madden attained through his operation, the Maddens decided that their country home and surrounding farmland should become a place where young heart patients could enjoy nature, sports, and recreation. It was their wish that the camp be accessible to all children who wished to come regardless of financial circumstance.
