About Dennis Deer
Lived 1972 – 2024 (aged 51). Dennis Deer was an American politician.
Dennis Deer (August 7, 1972 – June 23, 2024) was an American politician who served as the Cook County Commissioner for the 2nd district from 2017 until his death. He represented many neighborhoods in Chicago, including portions of the Loop, Near West Side, Near South Side, North Lawndale, Englewood, and Washington Park community areas. He was a member of the Democratic Party.
Early life and career Deer was born on August 7, 1972, and raised in the North Lawndale neighborhood of Chicago. He attended Collins High School in Chicago. After high school, he left the Chicago area to attend Jackson State University and obtained his Bachelor of Science in elementary/special education and Master of Science in rehabilitation psychology. Deer became interested in studying behavioral health after witnessing a murder at the age of 10 and suffering from post-traumatic stress disorder. He later obtained his Ph.D. in Christian psychology from Agape Theological Institute.
Deer returned to Chicago after university and founded Deer Rehabilitation Services, a therapy services provider in North Lawndale with a specialty in rehabilitating ex-offenders. He also co-founded and served on the executive committee of the North Lawndale Community Coordinating Council, a group of community stakeholders working to guide comprehensive planning and implementation in North Lawndale. In his capacity as president of Deer Rehabilitation Services, Deer graduated from the Goldman Sachs 10,000 Small Businesses program and the Chicago Urban League nextONE business acceleration program.
In 2018, Deer became the Vice-President of Organizational Health and Management for the Lawndale Christian Legal Center, a nonprofit provider of holistic legal services to people 24 years or younger that utilizes restorative justice. As of 2020, Deer was also a landlord. After failing to challenge the nomination papers of Chandler, Deer went on to come in third place behind Alderman Chandler and Joe Ann Bradley, a co-founder of Citizen's Action Group which worked towards eliminating prostitution in North Lawndale.
In 2007, Deer filed to run for 24th ward Democratic Committeeman in the 2008 primary, but withdrew as a candidate after facing a challenge to his nominating papers.
Deer served as the president of County Commissioner Robert Steele's fundraising committee until Steele's death in 2017 and considered Steele to be a mentor. He was also the chairman of an anti-violence task force that Steele's 2nd County District Community Advisory Council created with U.S. Representative Danny K. Davis. On July 13, 2017, a committee chaired by 24th ward Alderman and Democratic Committeeman, Michael Scott Jr., and made up of the Chicago Democratic ward committeepeople for all wards that made up the 2nd district was convened to select Steele's replacement to fill the rest of his term. Votes for the successor were weighted based on how many constituents of each ward committeeperson were also a constituent of the 2nd district.
Deer and 12 other candidates applied, including 20th ward Democratic Committeeman Kevin Bailey (a member of the selection committee), Reyahd Kazmi (the husband of City Clerk Anna M. Valencia), and State Representative and future City Treasurer Melissa Conyears. Conyears was also the wife of a selection committee member, 28th ward Alderman and Democratic Committeeman Jason Ervin. After appearing as a candidate, Conyears ultimately left prior to interviewing. During the primary campaign, Deer was endorsed by U.S. Representative Danny Davis, Alderman Michael Scott Jr., Alderman David Moore, former Cook County Board President and 2nd district Commissioner Bobbie Steele, the Chicago Sun-Times and the Chicago Tribune.
After winning the primary, Deer won the November 6, 2018, general election unopposed.
Cook County Commissioner
Tenure 2017 sweetened beverage tax repeal Shortly after Deer took office, the Board of Commissioners considered the repeal of the controversial penny-an-ounce tax on sugar- and artificially sweetened beverages that was supported by President of the Cook County Board of Commissioners Toni Preckwinkle. After initially supporting the tax at the time of his appointment, Deer ultimately voted for the successful repeal of the tax on October 11, 2017.
Racial justice On July 25, 2019, the Board of Commissioners passed Deer's resolution declaring racism and racial inequalities a public health crisis in Cook County. The resolution was intended to encourage growth in public health support networks to work towards decreases in racial disparities in health outcomes. Supporters of the bill believed it was important since communities of color are disproportionately affected by things such as exposure to lead, poor air quality, a lack of safe spaces, and inadequate health education.
On July 7, 2020, Deer along with fellow Commissioners Deborah Sims, Stanley Moore, Brandon Johnson, Bill Lowry and Donna Miller released a statement calling for passage of the Justice for Black Lives resolution. In referring to the changes demanded by recent Black Lives Matter protests the statement said, "As Black members of the Cook County Board we are determined to be the catalyst for that transformation in our county and beyond. The first step in that process is passage of the Justice for Black Lives Resolution, which would seek to redirect funds from our criminal justice system into systems and programs that support human needs and promote the health and welfare of the Black community." The non-binding resolution passed in a 15–1 vote on July 30, 2020. In July 2020, Commissioners Deer and Moore withdrew their separate resolutions and combined their resolutions to make Juneteenth a holiday in Cook County. The measure was unanimously passed in December 2020.
2020 census Deer served as one of the Vice-Chairs of the Cook County Complete Count Census Commission for the 2020 United States Census. In this capacity, he worked to help ensure everyone in Cook County was properly counted to make sure Cook County receives proper legislative representation and government funding in areas such as social services and infrastructure. On August 18, 2020, Deer co-hosted an event in Englewood giving out prizes to those who filled out the census with Alderman Stephanie Coleman and various local organizations.
Housing Deer supported the Just Housing Amendment that was passed by the Board of Commissioners on April 25, 2019, and went into effect January 1, 2020. The amendment prohibited landlords from denying housing applications based on arrest records or convictions that are more than 3 years old and required an individualized assessment of convictions less than 3 years old for otherwise qualified applicants. Deer decided he wanted to champion this issue as someone who is both a landlord and works with ex-incarcerated men and women. He stated, "There's no room for double jeopardy. People should not be required to pay over and over and over again for a crime they committed when they were 19."
Committee assignments As a member of the Cook County Board of Commissioners, Deer served on multiple committees of both the Board of Commissioners and the Forest Preserve District Board.
