Beloved husband, father, grandfather, and brother, Jan R. Mangan recently passed onto his Heavenly home on Thursday, January 24th, 2019. A lifelong educator, Jan dedicated over 53 years to teaching students math while imparting his sense of humor and encouragement. Jan believed in always giving his best whether teaching electronics for the military, selling real estate, establishing Plymouth Christian Academy, or teaching 10 years for DODDS overseas in Germany. He never shied away from a handyman project or serving the elderly, and just recently retired after instructing college courses locally. Jan, who led his family with God first, is survived by his wife of 61 years Patricia, his four grown children Mark Mangan (Lisa), Jill Mcmullan (Mark), Brad Mangan, and Leanne Bush (Craig). He also leaves behind 9 grandchildren and 4 great-grandchildren, as well as his sister Kay Ross (Don).
