Student Stories

Ryan Mihalic

Biology, Hammond

“The size of the classes was one of the major factors that influenced my decision. The smaller class size allowed me more interactions with the instructors, which allowed me to succeed and to do well.”

Carolyn Brunt

Biology, Highland

 “Faculty and staff make themselves available at the student’s convenience for any assistance the student may need, whether it be something as trivial as homework help or a topic of significance in that student’s life, such as course registration and career counseling. With the help of such admirable faculty, I graduated with B.S. degrees in both Biotechnology and Chemistry in four years.”

Keeley Mazurkiewicz

Biology, Manteno, Illinois

“The Department of Biological Sciences offered interesting and challenging classes, and the biology staff collaborated with other departments, which allowed me to pursue biochemical research projects.”
