Mr. Hanger has been a teacher at Loudoun County High for over 29 years now (since 1987). He currently teaches A.P. Biology and Honors Biology, as well as Chemistry. In addition, he has coached the girl's tennis team for 16 years; and the last 11 years has been the boy's tennis team coach. His educational background includes a bachelor's degree in biology from the University of Virginia, and a Masters of Science in molecular biology from Hood College, with thesis work completed at the National Institutes of Health. Mr. Hanger has also done work in the field of toxinology at USAMRIID in Fort Detrick for 7 summers.

(Chapter 17)Homework: access information through "Phoenix". Labs and papers started in class usually need some time at home to answer analysis questions, and since we do this on a daily basis, these assignments are posted in the classroom. Students can get help during office hours: 7:45 to 8:45 a.m., and during Raider Rally.Parents with concerns, please feel free to email me at:
