There are teachers, and then there are teachers like Larry Grimes, Science Department chair at Sierra High School where he has been a member of the faculty for the last 15 years. The father of three and grandfather of two who is celebrating 40 years of marriage this year with wife Sheri, teaches all four levels of biology offered at Sierra. They are Applied Biology for students who need special assistance in achieving academic success, College Prep for biology students who need to learn college-level skills, Physiology for those who are stepping up from regular biology to advance work, and AP (Advance Placement) Biology for those required to do college-level work.
