    Michele Gibson

    Michele grew up in eastern Iowa and has been a church pianist/organist her whole adult life. Although her work career was in accounting, playing piano has been a huge part of her life and opened so many opportunities over the years. She has lived in IL, AL, TX and WI, and always was lucky enough to find a church to share her music. Now in retirement, she enjoys reading, jigsaw puzzles and needlework. Every day she thanks God for her mom's encouragement to keep taking those piano lessons!
