" We enjoyed receiving your book, "Uncle Greg - A Tribute To My Son. Greg was a wonderful and accomplished young man and we are touched by his story." Cystic Fibrosis Foundation. This book is about Gregory Richard Carmichael. Greg fought a courageous battle against Cystic Fibrosis for 34 years. This is the story of his life as seen by his father Richard Carmichael. I wrote this book to preserve his memory. I hope that this book will also preserve the memory of Greg for his future nephews and nieces that will never have the pleasure of knowing him.
