Denise Rochelle Sims, affectionately known as 'Big Ma' to her grandchildren, passed away peacefully on July 29th 2024 at 5:40 AM in her hometown of Chicago Illinois, at Northwestern Memorial Hospital. Denise was born on May 19th 1963 to parents Mary Elizabeth Sims and Donald Walker. Her warmth and fun-loving personality was evident from an early age. She was the beloved older sister to Sonja Sims and Samantha Sims, in addition to being a caring aunt to Shamari Sims and Elizabeth Sims. Denise has two daughters Marcella Sims-Barnett and Lonette Sims, and four grandchildren from Marcella. Karvel Sims, Markus Barnett Jr., Malia Barnett, and youngest Mia Barnett. She loved her grandchildren and family. This was evident through the unconditional love and support that she taught and expressed to her children and grandchildren.

Denise spent her formative years attending Crispus Attuck Elementary school in the Bronzeville neighborhood of Chicago, and John Hope Middle School located in the Englewood community. Often she would tell her daughters of the fun she had when attending these schools and about her cherished memories growing up on the southside of Chicago. She graduated secondary school from Tilden High School also located on the southside of Chicago. Denise decided to further her education past high school and completed her associated degree from Robert Morris College in phlebotomy. This was an accomplishment she was very proud of as healthcare was a field Denise was always interested in.

Denise became ill with sarcoidosis suddenly at the age of 44. She battled this disease valiantly for 17 years until her passing. This speaks to her love of life and family. Her life was a testament to the unconditional love and support she showed her children and grandchildren.

Her experiences with illness and being an African American woman led her to develop an interest in issues affecting the black community. She often spent her time during her later years learning more about these issues and actively supporting her daughter Lonette's activism, which was something she was extremely proud of. Denise also found joy in spending time with her grandchildren, giving and supporting others, as well as decorating her home to reflect her beautiful personality.

Denise's memory will be treasured, and her presence sorely missed. Her garden is full of vibrant flowers, winding paths, and a warmth that will forever be cherished by those who had the privilege of knowing her. Rest in peace, Denise. Your legacy and spirit lives on. We love you always.
