Mr. John Mark Rinker

Hello, I am John Mark Rinker, and I am a teacher of AP United States History and IB History of the Americas here at RHHS. I LOVE TEACHING! I am wrapping up my 5th year here with Rockwall-Heath High School and the 26th year overall. In Social Studies subjects, I've taught every subject there is from 6th Grade Social Studies to 12th Grade United States Government. I like to tell my classes I've taught students from ages 10 to 70. Eight of my teaching years I worked for Frank Phillps College thus the 70-year-old :) 

Five years of my teaching experience has been in Private school in Nicaragua & Guatemala. Those five years are indeed some of my fondest memories both for the fantastic culture my wife and I got to know so well, and my first daughter Tori (15) was born in Managua, Nicaragua, and life has never really been the same. 

I have taught United States History at the AP/IB/College level for about 20 years of my teaching life; it is my passion. I was out of the country on 9/11, and those days and the days that followed, it has left an indelible stamp that has helped to make teaching history for me even more personal.

I've been married for 24 years to Jennifer Rinker; she is an ESL teacher at our sister school cross-town at Cain Middle School. Our youngest daughter Emily is wrapping up her 7th-grade year there, and Tori is a Freshman at Rockwall-Heath. Our family enjoys Rockwall for everything it offers for education and the many unusual cultural events and museums that are so near.

I look forward to many wonderful years teaching at Rockwall-Heath High School. I believe as a teacher and as a member of this astonishing community of educators. We can genuinely change the world, one child at a time.

If you should ever have a question or issue about your child's education, please reach out to me.
