    Welcome to Mr. Halko's Webpage
  • Who Am I?

    I was born and raised in Ashland, Pennsylvania, which is about two hours north of Chambersburg. I graduated from Cardinal Brennan High School in 1998. I then attended Nazareth College in Rochester, New York and majored in Physical Therapy. During my junior year I changed my major to Chemistry and transferred to Shippensburg University before the spring semester. I graduated from Shippensburg in 2003 and was hired by CASD at J. Frank Faust Jr. High as a Physical Science teacher. I spent one year at "Faust" and then I was transferred to CASHS to teach Chemistry. Since then, I have received my Masters in Educational Leadership from Shippensburg University and continue to teach Chemistry and Honors Chemistry at CASHS.
