Through his Lost Cleveland program, Dennis is entertaining and educating audiences while raising money to help find a cure for a rare disease.

Dennis and his wife, Mary, have five beautiful grandchildren. Two of their grandsons (Dylan and Sean) have been diagnosed with Ataxia-telangiectasia, more commonly known as A-T.

A-T is an extremely rare, genetic disease. A-T causes progressive loss of muscle control, immune system problems and a high rate of cancer. Sean is already a cancer survivor. He was treated for B-cell lymphoma when he was 2 years old.

Because A-T is so rare, it gets little attention and even less funding. The A-T Children’s Project (atcp.org) was started to raise funds for research and life improving therapies for children with A-T.

All of the proceeds of Dennis’ Lost Cleveland Memories® programs will be used to fund the work of the A-T Children’s Project.

To book a program:

Make a tax-deductible donation to the A-T Children’s Project for at least $100 or get in touch with Dennis
