Great job preparing students for AP Bio exam. Very inspirational. Made my child love biology. He's that teacher that made a difference.
Hartswick was a great teacher... He always treated me with respect even when I often didn't put as much ias I could have into his class. Both a great teacher and great person.
Mr. Hartswick is truly passionate about biology and it shows in every lecture. He understands teenagers and presents his fascination of biology to them in a truly effective way. Overal great teacher!
