Sandi Guenther

Welcome to our US History class. I am delighted to teach your children their last EOC tested content US History. This will be my 15th year of teaching history. I started teaching after spending some time in corporate american. My first teaching position was at Tejeda Middle School in Texas History. After 5 years I went to 8th grade US History for the next 7 years. I was blessed to have the opportunity to move to high school here at CT Johnson. It is by far my favorite teaching experience.

I am a mother of two daughters. Ashley is a teacher as well at Tejeda Middle School. Amber runs her own business as a Calligrapher and she also is a wedding planner. Amber is expecting our first grandchild in January. My husband Buddy is retired and takes care of the home and dog.

I am a firm believer in "it takes a village" so feel free to contact me anytime at
