Mary Ann Boher, 85, died January 31, 2022 at Sunrise Assisted Living in Crystal Lake, IL surrounded by her family.
Mary Ann was born on January 13, 1937 in Sterling, IL, the daughter of Paul Timothy and Mildred Mary (Flynn) McCormick. She attended St. Mary's School in Sterling, Polo High School, Mount St. Clare in Clinton, IA and was a 1954 graduate of Newman High School.
Mary Ann was an accomplished nursing professional who instilled the values of hard work and the importance of higher education onto her sons and her grandchildren. While raising her sons, she attended Sauk Valley Community College earning an Associate Degree in Nursing and graduated as a Registered Nurse. She was a secretary in the corporate office and later worked as a nurse at Northwestern Steel and Wire. It was during this time that her husband, Harry Pierceson died of cancer.
While a school nurse at Rock Falls High School, she met and married Fred Boher, and together they moved to Princeton, IL, where she worked in the emergency room at Perry Memorial Hospital. She and Fred later moved to Tucson, AZ, where they lived for over twenty-five years. In Tucson, she continued to work as an RN in the field of epidemiology. She was a senior epidemiologist at the University Medical Center, and later became an infection control manager and consultant with the Carondelet Health Network and St. Mary's Hospital of Tucson.
While living in Tucson, she volunteered as a docent at Sabino Canyon and was a member of the Tucson Chapter of the DAR. She and her husband Fred designed and built a beautiful home facing Sabino Canyon, where she welcomed and entertained countless family and friends. Mary Ann was a genealogy enthusiast, an avid reader and lifelong traveler. With her husband Fred, she took their grandchildren on countless Elderhostel trips across the United States. After Fred's death, she relocated to Illinois to be near her family, and resided there for the last three and a half years at Sunrise Assisted Living in Crystal Lake, where she continued to share her knowledge of infectious disease protocols with staff during the first stages of COVID.
Survivors include her family consisting of her son, Steven (Neive) Burger of Fox River Grove, IL and grandsons Nicholas of Chicago and Matthew of State College, PA; her son Jeff Burger of Clinton, IL; granddaughter Jaclyn (Kyle) Rogowski and great grandchildren Jackson and Kynsie of Mesa, AZ; granddaughter Melissa (Zach) Ruemelin and great grandchildren Logan and Brody of Lake in the Hills, IL; her son Gregg (Linda) Burger of Oaklyn, NJ; her brother, Thomas (Debbie) McCormick of Camanche, IA; brother-in-law Jerry Crenshaw of Morrison, IL as well as several nieces and nephews.
She was preceded in death by her parents; husbands Harry Pierceson and Fred Boher; daughter-in-law Julie (Jeff) Burger; sister Nancy and brother-in-law P.D. Strunk; infant sister Patricia; sister-in-law Janice Pierceson (Jerry) Crenshaw and sister-in-law Grace Boher Wood.
Per her request, her cremated remains will be buried between her husbands Harry Pierceson and Fred Boher in the Tampico Memorial Cemetery during a graveside family service later this year, at which time her life will be celebrated.
