Marlene Marie (Osterman) Wielgus age 90 of Lake Delton, Wisconsin passed away September 14th at 2:14 pm.

Marlene was born in Peoria, Illinois to Helen Marshall and Homer Osterman June 20, 1935.

Marlene was preceded in death by her husband of 40 years Robert J. Wielgus.

She is survived by her children (Margo, Nadine, Steve, Teri, Sue) grandchildren and great grandchildren.

Marlene was retired from GTE, she loved helping customers and prided herself on being able to calm down irate customers. She could talk to anyone which made her a very good antique picker which she did for many years.

Marlene loved all animals especially her dogs. Music was always a part of her life she sang and played piano. She was talented enough to be asked to sing at Yellowstone for a summer as a youth. Later in life could be heard doing karaoke and always receiving a generous round of applause. She also enjoyed fishing, gardening, playing cards and reading.

A special thanks goes to those whose help was invaluable in her last days: Nadine Resler, staff at Mother Mary at Tivoli, and SSM Hospice.
