Deb Brown
Activity Director
Deb started her career at Prairie Manor Care Center in 1997 as Heather Haus Manager when it was still an Independent Living facility for seniors. When Prairie Manor obtained their Assisted Living License for Heather Haus, she opted to go part-time in the Activity Department for a few years while raising her "small army" of children alongside her husband, Jared. During that time, she realized how much she loves enriching the lives of the residents. Deb obtained her Activity Director certification through Ridgewater College in 2017. She secured employment elsewhere until the Activity Director position at Prairie Manor opened at the end of 2022, and it immediately felt as if she were back home. Deb and Jared live in Blooming Prairie with their 5 youngest children and enjoy staying connected with their 5 older children, their spouses/significant others and their two grandchildren.

She works with Lesa Dahl-Leland who is a Consultant Registered and Licensed Dietitian. Jackie lives on a farm in rural Steele County with her boyfriend, Andrew, and their three boys (Lukas, Evan, and Jace) where they raise cattle, hogs, and crops. She enjoys spending time with their extended family, helping the boys get their livestock ready to show at the county fair, and fishing trips with her family-their favorite is the annual trip to Canada. Jackie loves working at Prairie Manor because it is a close-knit community that offers quality care for our residents.
