I have taught at all 3 levels (Elm, Middle, High) in the K-12 public school system working with students with special needs. I am a strong public advocate for my students, teachers, and the public education profession. Both of my parents were Educators and Union members! Besides education, my hobbies include photography, painting, and traveling. Finally, I am Honored/Proud to be SEA’s VP.

Judy Ngying has been teaching for 19 years. Sixteen of those years were in Volusia County. She has spent most of that time teaching high school chemistry.  Her husband, Sean, is also a teacher. They both have been proud union members since the first day on the job. They have one daughter, Victoria, who works as an Information Technology specialist after graduating from Daytona State. Judy’s hobbies include motorcycles, gardening, going to the beach, and her many cats.

Karen graduated Summa Cum Laude from the University of Montevallo with a BS degree in Family and Consumer Science, minors in education and biology.  She has taught for 23 years and is a Culinary Arts teacher at Oviedo High School.  When not advocating for students and teachers, Karen volunteers with Turning 22, a program for young adults with learning disabilities.  She is a member of Alpha Delta Kappa, an international honorary organization dedicated to educational excellence, altruism and world understanding. She loves to travel and spend time with her family and Chihuahuas.

As your SEA President, I have been a Union member and advocate for teachers and children for 30 years.  Our goal for the next two years is to work together to increase membership, grow leaders and be a piece of a strong Union.

 Our Union is a team that is like a puzzle. 

EVERY piece is Vital…..
