About Mister K

Mr. Kaltreider, or most famously known as Mister K, is an elite early childhood educator. He received his Master of Education in Special Education from The Pennsylvania State University. He also received his Bachelor of Science in Elementary Education with a PreK-4th grade Instructional II teacher certificate. He teaches his students to always follow the Golden Rule:“Treat Others As You Want To Be Treated.”


Mister K believes that the aim of education is to make life-long, independent learners who will learn continuously in an ever-changing world and to make an exceptional impact on society. Education needs to be an interactive experience where students learn from the teacher and then explore, discover, and communicate with the world around them.
