Kitty Ordway, Trustee

Kitty is a grandmother of three MIS students. She has been involved in independent school governance for over 30 years and has traveled and lived globally. Kitty was initially intrigued by the IB program and the Spanish immersion offered at MIS. Global awareness is important to her, and when Kitty saw this principle in action at MIS, she was eager to get more involved herself.

Kitty currently teaches an MIS after school art class called “Animals Around the World.” She is known as “Grandma Kitty” around campus and loves to get spontaneous “hallway hugs” when she is in the building. Her class is based on the premise that there is no right or wrong way to sculpt animals, there is only a difference in style. She encourages students to develop their own style as they learn about familiar and exotic animals.
