Profile

I love math! I know not everyone feels the same way, and that's completely okay! I hope that this course helps you build the skills and confidence you need to move forward on your educational journey. I truly believe math can open doors to exciting opportunities, and I want you to feel ready to walk through them.

In my classes, I do my best to keep things engaging and fun. I use a lot of group work because I have found that students learn best when they can work and grow together. I am excited to get to know you and help you succeed in this course and beyond!
