Hello, my name is David Vassar. This is my 17th year teaching various social studies and my 5th year at Riverdale. Welcome to my web page for Riverdale High School. You will be able to find several documents that students and parents can use to better understand what we are doing in this class. Please use the navigation bar on the left side of the screen. You can email me at any time at email@example.com . I will respond ASAP.
