Mrs. Rachael Guillen - Welcome!

I am thrilled to offer biological science courses at YWLA.  Biology education is my passion!  I have a bachelor's degree in Biology with a minor in Physical Science, a master's degree in teaching with an emphasis in Secondary Science, and am currently working on my doctorate in Curriculum, Instruction, and Assessment.  My students receive up to date information based on current research- both in science and educational strategies.  All biology classes receive a course calendar prior to the start of the school; all assignments, tests, and major projects are on the calendar.  Please use it to help manage your time.  If you have any concerns, please contact me ASAP.
