Mr. Kollmar

I have been a teacher since 1992.  Prior to that I was Diving Officer in the US Navy.  I joined the Yonkers Public Schools Team in November of 1997, and have been working in Gorton since I arrived as a teacher in Yonkers.  I am currently teaching Earth Science and Physics.  

I'll be available during the following Hours, during the school shutdown due to Corona Virus: 9:30 AM - 11:30 AM and from 1:00 PM - 2:30 PM  to answer questions, and provide help with assignments.
