Marianne Piet, 78, of Naperville, formerly of Orland Park and Chicago, passed away on Sunday July 18, 2021, at her home. She was born on September 22, 1942, in Chicago IL. Loving wife of the late Edward J. Pietrzyk, dear mother of Mark Pietrzyk, Christine (Edmund) Kearney, and Ken Pietrzyk, adoring grandmother of Sarah and Brendan, sister of Jeanne (the late Walter) Simak, and the late Thomas (Carol) Patzin. She is also survived by many nieces and nephews. Marianne grew up in Chicago and attended Kelly High School. At the age of 36 she went to college, first at Moraine Valley Junior College, later finishing her Bachelor of Arts degree at The University of Illinois at Chicago. She continued on to earn multiple graduate degrees in the field of social work, first earning her Master of Social Work through the University of Illinois at Chicago Jane Addams School of Social Work. While in her 50's Marianne once more returned to the classroom, earning her Ph.D. in social work from Loyola University in Chicago. Marianne was a trailblazer. As a national expert in the treatment of domestic violence offenders, she was a sought-after speaker for both professional research and training conferences, as well as an author of professional journal articles and book chapters. Her treatment protocols are still often used and seen as the standard of care in working with domestic violence offenders. Her broader clinical work involved 20 years of practice in the emergency room at Christ Hospital, private practice, and many pro-bono endeavors. As Professor of Social Work at Aurora University, Marianne committed herself to the education and training of the next generation of social workers. She was a popular teacher whom students praised for her ability to provide real-world consultation and guidance. Marianne was most proud of the fact that both her daughter and granddaughter have followed in her footsteps, becoming Licensed Clinical Social Workers. A brief outdoor celebration of Marianne's life will be held on Thursday, July 22 at 10:15 am at the DuPage Unitarian Universalist Church at 1828 Old Naperville Rd, Naperville IL. 60563 with a luncheon to follow at Maggiano's Naperville.
