Shirley Woodson  Organist

Patty Mason  Office Administrator

Coming from a musical family, Shirley Woodson started piano at age six, organ as a teenager, and majored in organ performance. Burned out from music and leaving the church while living in Hawaii, she quit playing for more than ten years.


Coming home to San Diego, through God’s intervention, Shirley took an organ job at Northminster Presbyterian Church when her cousin retired. During her 10 years playing there, God took hold of her life. She left Northminster for a two-year break from music. God again intervened, bringing her to Trinity Church when her boss’s wife wanted to retire to follow her son’s baseball career. 
She began playing on January 1, 1997, and continues to be an active member of Trinity Church.
