Three Rivers is proud to be hosting students from Brewster School District as they complete part of their senior requirements by shadowing departments in which they are interested. Rosa is in PR/Marketing with Majors Creative. Marlisa is in Accounting with Jennifer Riggan Bach. Jennifer is in Human Resources with Anita Dyer Fisk.

According to Marlisa, "this job shadow has been helpful to learn more about the major I plan to study in college and see what you're getting into."

With a few more students still to finish up we hope to share more of their experiences as well. It has been great to have the students here. It is always great to see bright faces and have the opportunity to serve our community by sharing our knowledge with the communities next work force. Thank you to Rob Dezelman, Anita, and Sandra for organizing all these students and supporting our community.
