Jessica Droste, CPA, Manager

Jessica joined Maner Costerisan in 2018 and is a manager in the Accounting and Outsourced Solutions department. She is responsible for providing traditional accounting and bookkeeping services to the firm’s clients. She also offers expert training to clients going through transitionary periods. In addition to her work in accounting, Jessica also is a member of the firm’s Consulting team, where she focuses on building out data analytics offerings.

Prior to joining the firm, Jessica assisted her father with bookkeeping for his small business. She was also a graduate assistant at Michigan State University while working on her master’s in accounting. Jessica chose to enter this industry because of the impact she can make on others and the opportunity for constant learning – no day is ever the same. She enjoys working with Maner’s smaller business clients because she can see the true difference she makes in people’s lives.

Jessica lives in Westphalia, Michigan, with her husband, Tanner. In her free time, she enjoys playing and watching sports, hosting friends and family, bike riding, and cooking and baking.

My goal is to make others know they are loved and cared for and never alone. If that means lending a listening ear, training someone multiple times, or providing extra help, it is worth it to me.
