Mr. Keyes is in his second year as a teacher here at York High School, but he is very familiar with the school.  A 1995 graduate, he received his B.S. in chemical engineering at Tulane University in New Orleans.  After working in this field for a few years, Mr. Keyes decided to change careers.  Currently, he teaches chemistry, but he hopes to teach math as well at some point.  This is his fourth year as the boys tennis coach; he was the assistant coach the previous two years.
