Mrs. Diane Key

Parents and Students,

I look forward to the 2022-2023 school year.  It is a privilege to work with your children and facilitate building a strong foundation of academic skills such as reading and math.

I would like to introduce myself.  I am Mrs. Key, the General Education Kindergarten Teacher in the classroom.  In May of 2012, I received a Master's Degree in the Arts of Teaching from Webster University.  Since graduation, I have been an educator working as a substitute teacher for two years,  a special education aide, and a teacher assistant.  This will be my seventh year at Mullanphy Elementary.  In addition to teaching, my husband and I have three children:  Joclyn (23), Nathan (20), and Jonathan (18).  On weekends, we attend cross country running in the fall and track events in the spring.

Thank you in advance for all of your efforts in supporting your students to succeed. My goal is to encourage your students to work to their full potential. 

School supplies needed for Kindergarten will be:  pencils, crayons, and headphones for the iPad.
