LRHSD Math and Science Career Expo – November 14, 2011

Thanks to all the students and parents for coming.  My big fear with these types of presentations is that no one will show up.

Good luck in high school, and with your college selections.  If you have any questions, feel free to contact Sarah or me any time.
