Andrea Mammen

January 7, 1983 ~ September 12, 2020 (age 37)


Andrea Mammen, 37, of Morton, formerly of Delavan, passed away at 4:57 am Saturday, September 12, 2020 at OSF St. Francis Medical Center in Peoria. 

She was born January 7, 1983 in Peoria to Douglas F. and Kathy J. Wagoner Smith.  She married Matt Mammen on May 5, 2013 in Bartonville, and he survives. 

Also surviving are her parents, Doug and Kathy Smith of Delavan; one son, Russell Mammen of Morton; one brother, Jacob (Samantha) Smith of Deer Creek; and Matt’s family, Rick and Callie Mammen, Melody (Clint) Stout, and Judge and Bev Groenewold. 

She was preceded in death by her paternal grandparents; maternal grandmother; and one uncle. 

Andrea graduated from Delavan High School, Illinois Central College, Illinois State University, and received her doctorate from the Chicago School of Professional Psychology.   

She was employed as a clinical psychologist at Psychology Specialists and led the Pekin office. 

Andrea loved her family, friends, and all animals, especially Cheetah and Kitten.  Her favorite past time was engulfing herself in a good book.  Aside from being a loving wife, mother, daughter, sister, and friend; she was also a perfect model of positivity, kindness, generosity, acceptance, empathy, and hope.  Everyone she met is better for having known and been loved by her. 

She was a member of First United Methodist Church in Morton, where her funeral will be at 10:00 am Friday, September 18, 2020.  Pastor Gabe Wanck will officiate.  Visitation will be from 5 to 7:30 pm Thursday at Davis-Oswald Funeral Home in Delavan.  Burial will be in Prairie Rest Cemetery in Delavan.  Social distancing guidelines will be observed during the visitation and funeral and masks are required. 

Memorials may be made to an educational fund for Russell established at CEFCU in Morton.
