This is the best place to get information about Chemistry classes. However, homework videos and digital assignments will be posted on Google Classroom. Other assignments will be posted on this site along with additional study materials and aids. Please click on the links to find more information about my classes. Some of the links will be password protected due to copyright laws. Every student enrolled in my classes will receive a password for these documents.

Although I am usually available before and after school for tutorials. After school is by appointment only.
