All Students Spring 2018:

Welcome Back!!

  • Warning: Parking can sometimes be difficult during the first few weeks of the semester.  With the construction taking place and the portable buildings now taking up space in the parking lots, you may want to arrive early, just in case, to find a parking space in the smaller parking lots!  By the way, If you park in a no parking zone, handicap zone, staff parking, etc. without the appropriate placards and/or stickers you will be ticketed!  Parking enforcement will be in full force beginning with the first day of classes!

  • Warning:  If you do not come to the first day of class you may lose your space to someone on the the wait list who does show up for class!

  • The campus imail system has  transitioned to a Gmail system during 2013.  You will need to activate your account in order to use the gmail system!

All ARC Students: 

  • This is just a reminder that the Science Success Center will be open for the Fall and Summer Semesters.. students are taught Study Skills such as annotation of text, paraphrasing, concept mapping, graphics reading, etc, within the context of their science course. All of the homework students do comes from the text, notes and handouts of YOUR course. Research shows that students who finish the SSC have about 15-20% higher success rates than students who do not complete the course. Students are required to have 6 to 8 meetings of 20 to 30 minutes with an IA, and they must complete all of the required homework assignments.

    • If you have any questions about the Success Center, please contact the Success Center directly and talk to one of the IAs (484-8204 or

  • The ARC Career and Job Opportunity Center offers an array of resources to assist students in choosing career options, preparing for employment, and researching current job openings. 

  • The campus IT department recently changed the server for our websites, which changed the addresses of most of the links included in my pages.  I have updated my website, but if you come across a link that doesn't work, please let me know, by contacting me at:
