Many have in-house interns, and all have valuable connections to local businesses. Certain companies have set up internships with Wheaton College. They encourage Wheaton students to apply because they are interested in Wheaton College. Information about these sites can be found in the Career Services Center and by speaking to Kent Seibert or Pat Unander. Talk to them, if possible.
Professors are a valuable resource, for contacts in their field as well as references.
Stop by the Career Services Center. Some are paid, some are not. Schedule an internship placement counseling session to find an internship site which meets your goals and needs. Some employers may choose to pay a salary while others may not. Monetary compensation is not necessarily an indicator that the internship site will provide the best learning experience.
