Welcome! It is a great pleasure to be teaching at Valhalla High School. This is my fourth year teaching at Valhalla, but I have been the Head Lacrosse Coach here since 2012. For the 2017-2018 school year, I will be teaching Pre-AP World History and Hum II World History. Please refer to this site for important class information and resources. See specific class pages in the Navigation bar on the left.

If you have any questions or concerns, please feel free to email me at jbalistreri@guhsd.net or call me directly at (619) 593-5483. Email is preferred.
