Sue Brown

Sandra Sue Zimmerman was born July 13, 1945, in Fort Bragg, N.C., to Dr. Gifford and Carol Mathwig Zimmerman. After Giff was discharged from the Army, the family moved to the Zimmerman’s home town in Geneseo, Ill.
Sue graduated from Geneseo High School in 1963 and cum laude from Lawrence University in Appleton, Wis., in 1967. At Lawrence, Sue was a member of Delta Gamma, Mortar Board Senior Honor Society for scholarship, leadership and service and many other organizations and activities. Family friend and fellow Geneseo native Dr. W. O. “Bill” Farber of the University of South Dakota introduced Sue to Richard E. “Dick” Brown on New Year’s Eve in 1965, and the couple was married June 17, 1967. 
The first five years of Sue’s married life were spent in Washington, D.C., where she served for a year as legislative secretary for Congressman Tom Railsback of Illinois and then began a management career as a housing specialist with the U.S. Department of Housing and Urban Development. Sue continued this work when the couple moved to Omaha, Neb., in 1972.  While there, Sue began her role as a mother with the birth of her children Matthew, Terra and Jennifer.
The family moved to Sioux Falls in 1979, where Sue established a research and community development consulting business.  She served on the boards of many nonprofit organizations in the fields of education, housing and women’s issues including the Sioux Falls Housing and Redevelopment Commission, South Dakota Housing Development Authority, YWCA, Habitat for Humanity, United Way and Volunteers of America.  
She also served on the boards of the Sioux Falls Area Chamber of Commerce and Downtown Rotary. She served two terms on the Sioux Falls School Board, worked as a financial services representative for her husband’s business and became president/CEO the Sioux Falls Area Community Foundation in 1995.  She retired from that position in 2006. Both the school board and community foundation were works that matched Sue’s passions, and she considered these opportunities two of the turning points in her life. 
Sue and Dick moved to Custer, S.D., in 2007 to be closer to their grandchildren. Sue served on the boards of Custer Rotary, Custer Youth and Alumni Foundation and the Custer county planning commission and briefly on the board of the Black Hills Area Community Foundation. Sue and Dick formed Brown Associates, LLP and were contracted as South Dakota Parks and Wildlife Foundation development directors in 2008. Once again, she regarded work as an extension of her life and her skills.
She received many awards for her community service, including the Dave Birkeland Award for leadership in Sioux Falls, YWCA award for women’s leadership and Volunteers of America Youth Service Award. She was inducted into the South Dakota Hall of Fame in 2008 and was named a Friend of the Sioux Falls Area Community Foundation in 2018. In addition to community service, she enjoyed reading, sewing, fitness activities (she completed many half-marathons), contemplating God’s many blessings and spending time with her family. 
While she regarded work as an extension of her life and her skills, she believed her best jobs were that of a wife, mother and grandmother.
Sue passed away peacefully in her home in the Black Hills surrounded by her family May 10, 2020, from metastatic breast cancer. She was 74.
A celebration of Sue’s life and legacy will be announced at a future date due to current national health conditions.
She was grateful for her family: her husband, Richard Ellsworth “Dick” Brown; her children – Matthew McCafferty Brown (Dr. Joy Falkenburg) of Custer and their children Nancy Briley, Ryken and Lincoln Ellsworth; Terra Leigh (David Reynolds II) of Valparaiso, Ind., and their son David III and daughter Catherine Briley; and Jennifer Briley (Mark Holloway) of Minneapolis, Minn., and their son Ryan Richard and daughter Madeline; and her siblings – sister Terry (Dr. Patrick) Wyffels of East Peoria, Ill., and their son, daughter-in-law, and granddaughter; and brother Gifford R. Zimmerman of Evanston, Ill., and his son and daughter. Living close to Dick’s family most of her life, she claimed that family as her own as well.
Her parents preceded her in death.
In lieu of flowers, Sue asked that memorial gifts be made to the Sioux Falls Area Community Foundation, the Custer Community Foundation, the Black Hills Area Community Foundation, the South Dakota Parks and Wildlife Foundation or the Healing Garden at Monument Health Custer in care of Dr. Joy Falkenburg.
Arrangements have been placed in the care of Chamberlain McColley’s Funeral Home in Custer. Written condolences and guestbook entries may be made at
