Sarah R. Adler

Business Solutions Supervisor
Forest County Potawatomi Community

I was born and raised in Crandon, WI, surrounded by family, sports and racing! Graduated from college in 2002 and moved to Chicago for one year before returning home. This is where I started working for a technology company and assigned my first document management project with Forest County Potawatomi. This started out as overseeing the project, became certified in the product and continued the implementation of the solution set. This transitioned into the application support role and gained knowledge and experience in processes and workflow within the government. From there I earned my way into the Business Solutions Supervisor and oversee the business process analysts, the service desk team and the new media services department.

Upon returning back home, I also met my husband, Nate, of 12 years and we have 3 children ages 22, 10 and 9. Our kids keep our lives very busy with school, basketball, wrestling, baseball, and softball. In our spare time, we enjoy the outdoors as much as we can with camping, fishing, waterskiing, downhill skiing, hunting and riding dirt bikes!
