About Me

My name is Grant Guillen.  I am a proud Bonita Bearcat!  I graduated from Bonita in 2009 and went on to get my BA in History from Cal Poly San Luis Obispo.  From there I returned home and received my teaching credential from the University of La Verne.  I am in my 3rd year of teaching, my first at Bonita.  Go Bearcats!
