About SI for this Course

Organic Chemistry is often thought of as one of the most difficult classes offered; however, with a few tips and tricks and a lot of practice, O-Chem can be quickly mastered. I will utilize worksheets and breakout activities to help you master O-Chem's tricky topics.

SI is a friendly resource intended to enrich and bolster student learning. Each regular session will be 50 minutes in length and test review sessions will be 1 hour and 50 minutes in length.

If you have any questions you would like to discuss with me, feel free to do so! I love helping students (as I plan to one day teach High School Chemistry) and always look forward to refining my craft. Please email at
