Mr. Dennis Petercsak

I have been teaching for a total of 9 years now, and I have taught Biology, Physics and AP physics here at Hauppauge High School. Besides loving and teaching almost all of the sciences, I spend a lot of time out side of class on my bicycle. I do many local cycling events such as the MS bike tour in which I raised money to help find a cure for MS and rode my bike from Southampton to Montauk and back, a total of 100 miles in 5 and a half hours. I also do other outdoor activities such as Hiking, Mountain Biking, Kayaking etc etc etc.
