"In the Key of M" chronicles the distinguished life and career of megachurch Bishop Dr. Walter Thomas Richardson, including his rhetorical skill, musical gifting and studious nature that manifested opportunities allowing him to help transform his South Florida community. He has been "the first" in many instances throughout his career, such as the first black president of the YMCA in South Dade. He has interacted or been commissioned by every U.S. president since George H. W. Bush to help his community in some form. His legacy in Christian music, ministry, community reform and social justice is detailed in this book. His hope is that his contributions, which are detailed in the book, will become an inspiration so that ambitious young people who want to work in ministry and community endeavors can move forward with more wisdom, understanding, and hope. "In the Key of M" doesn't detail the life of a perfect man, but it does detail the life of a man, Dr. Walter T. Richardson, who has been perfected by his decision to persevere for his family, his community and church.
