Mrs. Karin Montemayor

Hello! I'm Mrs. Montemayor and this will be my 9th year teaching at MacArthur High School. 

I have a wonderful husband and 2 beautiful children. Daniel is 3 and Andrea is 18 months- they fill my heart and keep me very busy. I love spending time with family, reading, traveling, and just being outdoors. 

I'm originally from Guatemala and moved to the states at a young age. I am a product of NEISD, went to Bush MS and Reagan HS. I received a bachelors degree in Biology from Texas Christian University and a master of arts degree in Curriculum and Instruction from the University of Texas at San Antonio. 

I will be teaching Biology as well as heading up the Dual Language program at Mac. Teaching biology in Spanish will certainly be something new for me but I am very excited about this new endeavor.
