Most students aren't bad at math. They've just never had it explained in a way that works for them.

I'm Rich Hollinger — a high school math teacher who builds personalized systems that replace frustration with understanding. One student at a time.

The system is broken. Not your student.

Most students who struggle in math aren't missing ability. They're missing a system that was ever actually built for how they think.

Somewhere along the way, a bad explanation replaced curiosity with shame. A skipped concept became a wall. And the wall became an identity: "I'm just not a math person."

That's what I fix.

Hi, I'm Rich.

I was the kid in the back of class who didn't need to pay attention. Smart enough to coast. Then college hit — and coasting stopped working.

No study skills. No system. I failed courses. So I went back to fundamentals, built a process, and learned how my brain actually worked. When I did — things didn't just improve. They compounded.

That experience became my teaching philosophy. I spent four years proving it inside San Marino High School — one of the most competitive public campuses in Southern California. I coached a math team to a league championship after a decade-long drought. I created state test prep materials that went school-wide. My principal calls me one of the best on campus.

MathLedX is that same energy — now available one on one.

Work with me

Three things I do differently

I diagnose before I teach

Every student arrives with a different broken link in their chain. I find it before I start explaining anything.

I build around how you actually think

Not one explanation delivered one way. I adapt in real time until the concept clicks — then we build from there.

I use competition to build confidence

Timed challenges, structured retakes, and immediate feedback — the same methods that work inside a high-performing classroom.

Who this is for

What a session actually looks like

Not just "watch me solve it." Every session is built around what the student needs to understand — not just what they need to finish.

We break the problem down

Every concept is decomposed into clear, manageable steps — so nothing feels overwhelming or out of reach.

I ask before I tell

Instead of just explaining, I ask questions that guide students to the answer themselves — building real understanding, not dependence.

We know where you stand

Students always know exactly what they understand and what to focus on next — no vague "it'll click eventually."
