“Mr. Mentzer helped my child get back on track through a challenging 7th grade math year. My child and her teacher weren't clicking, and Mr. Mentzer helped bridge the gap. Mr. Mentzer was flexible about scheduling when things came up or activities required a change in our usual meeting time.”
Three pillars, one collective
Honestly, most kids need more than just a tutor. They need someone who knows the subject, someone who knows how schools work, and someone who can help them build the habits that make all of it stick. We do all three.
Tutoring
One-on-one sessions built around your kid's real learning data. We start where they actually are, not where the textbook says they should be.
- Math, pre-algebra, and Algebra I
- Science, reading, and writing as we grow
- Test and assessment prep
Education Consulting
Custom learning plans, school transition support, IEP and 504 navigation, placement guidance. From teachers who know how these systems work because we've worked inside them.
- Custom learning plans
- IEP and 504 support
- School placement and transitions
Academic Coaching
For kids who can do the work but get stuck starting, organizing, or finishing it. We help them build the habits to push through.
- Executive-function support
- Study skills and routines
- Goal-setting and accountability
Not sure which pillar fits? Tell us about your student and we’ll point you to the right one.
A small team you can actually meet
We grow this roster slowly and on purpose. Every tutor is a licensed teacher with real classroom experience — added by invitation, not by sign-up form. A small, hand-picked team means your child works with a genuine educator, every session.
For the past decade, I've worked in classrooms across DC, Virginia, and Pennsylvania as a teacher, team lead, and district curriculum developer. Today I teach 5th grade Math in a DC public school. Before that, I taught middle school science, led a 7th grade team at a DC middle school, developed curriculum at the district level, and ran the student curriculum and summer camp for the Andrew L. Hicks Jr. Foundation.
What ties it all together is range. I've taught the same concepts dozens of ways to dozens of students, so I know exactly where kids tend to stall out on fractions, ratios, or equations, and I almost always have another way in. I plan around real data, differentiate for every kind of learner including students with IEP, 504, and ML plans, and I'm relentless about making rigorous content feel within reach.
I hold an M.S.Ed. in Educational Leadership from Old Dominion (2018), a DC Pre-K–12 administrator license (2025), and teaching licenses in DC, (previously Virginia, and Pennsylvania, too). I'm currently on sabbatical from my doctorate in Education Policy at Drexel.
Tutoring is where it all comes together in its most personal form: one student, one goal, real progress.
- 10+ years teaching across DC, Virginia, and Pennsylvania
- 5th Grade Math Teacher, DC-based public school
- Former 7th Grade Team Lead & District-level Curriculum Developer (DC)
- M.S.Ed. in Educational Leadership, Old Dominion University (2018)
- B.S. in Middle Level Education, Eastern University
A seat with your name on it?
We’re looking for experienced teachers across more subjects, grade bands, and pillars. If that sounds like you, we’d love to talk.
Every plan is built for your kid
No two kids show up at the same place, so no two of our plans look the same. Here’s how we make each one count.
Start with the data
Before we get started, we ask for your child's i-Ready scores (or whatever diagnostic their school uses). That tells us which skills are solid and which need work, so nobody wastes time guessing.
Anchor to standards
We build every plan around the Common Core standards your child is held to in school. That way our work reinforces what's happening in their classroom instead of competing with it.
Pull from many curriculums
We pull from i-Ready, Eureka Math, and a stack of other proven curriculums to find the explanation and practice that finally makes a concept click.
What a session actually looks like
Sessions run on Google Meet with a shared live workspace (Google Sheets / screen sharing). Here’s the rhythm we use most of the time. Every session is different, and the structure bends to fit your kid.
Hi and recap
We open with a quick check-in and a recap of last week. What stuck, what was confusing, what came up at school.
Set the learning target
We name the goal for today out loud, in plain language. Your kid knows exactly what we’re aiming at.
Teacher-led instruction
I walk through the new concept with worked examples on the shared workspace. Visual, paced, with room for questions.
Student-led practice
Your kid drives. Real problems, connected to grade-level standardized testing, with me as a thinking partner.
Exit ticket
A short check on what stuck, what to revisit next time, and a tiny preview of where we’re headed.
Or homework-driven, if that’s what you need
Maybe your kid just needs help with their homework. Through the live Google Sheet or screen sharing, we work through whatever they brought to the session. The five-stage rhythm is a starting point, not a script. Everything is custom.

What families say
Mr. Mentzer helped my child get back on track through a challenging 7th grade math year. My child and her teacher weren't clicking, and Mr. Mentzer helped bridge the gap. Mr. Mentzer was flexible about scheduling when things came up or activities required a change in our usual meeting time.
Mr. Mentzer was an incredible math tutor for my rising 6th grader. He was patient, kind, and always energetic. My son loved working with him and made huge strides in just one summer.
