Career Experience

I recently retired after 35 years of teaching college chemistry and still teach part-time. I taught almost every course in the undergraduate chemistry curriculum at one time or another but have taught mostly General Chemistry and Organic Chemistry. I recently celebrated my eleventh anniversary of tutoring with Tutor.com. I have served as a Tutor.com Subject Matter Expert and have also reviewed the sessions of other tutors for content correctness. In addition, I have conducted interviews of prospective tutors and have reviewed the applicant interviews conducted by others.

I Love Tutoring Because

I love working with students to find the ways they can understand best. I like to use everyday analogies to help make chemistry concepts easier. My favorite part is that moment when the student really "gets it."

Other Interests

Gardening, Knitting, Quilting

Mary G is literally a life saver, organic chemistry is one of the toughest subject I’ve taken in my life time and she has helped me become very confident in myself with organic chemistry, I’ve seen a couple of tutors on this platform but no one has topped Mary for me, she doesn’t make me feel ashamed of asking questions she’s super patient with me and actually explains things for me to understand
