Gadsden State Community College

Science Division Faculty

The Science Division Faculty brings together a diverse group of individuals with backgrounds in Aquatic Science, Astronomy, Biology, Chemistry, and Physics. These faculty members are committed to assist Gadsden State's students with issues of advisement and to provide assistance as students consider their transfer to four-year senior institutions. In addition, many students find great advantage in the fact that our class sizes are small so that instructors are able to provide assistance on an individual level.

Whether a student is seeking a degree or a certificate in a Gadsden State program or taking Gadsden State courses to prepare to transfer into a program in which the College does not offer an associate degree, the student must confer with the Gadsden State advisor assigned for his/her program or area of study. If a student has not yet decided on a program of study, he/she must confer with the counselor(s) for undecided/undeclared students.
Students are responsible for speaking with an advisor who will work with the student in planning courses for the upcoming semester(s).
