**Who is Matt Groden?**

Hey there! I'm Matt. I make videos that make math click for students.

The energy in my videos comes from my love for math and teaching. I am grateful to have spent over 10 years teaching in a public high school and middle school in Southeast, Pennsylvania. I loved coming into class every day to teach everything from Algebra 1 to those who struggle with math through to teaching AP Calculus AB and BC to those who love math and everyone in between. I thought to bring the many inspiring lessons and moments I was fortunate my students and I shared together to the world with these videos.

So here I am making videos for you whether you are learning basic math in middle school all the way up through advanced levels of Calculus in college. I am driven to help you to see math does not need to be difficult. I want to pull you into the screen with me so you can see how math connects. And, of course, I am here to help you understand the difficult concepts so you can get homework help, study for tests, and get better grades with these math video tutorials.
