Joshua Lizardi
Founder & Lead Mathematics Coach
Northstar was founded by Joshua Lizardi around a simple idea: math tutoring should be personal and flexible, and it should help students understand the material instead of only getting through an assignment. Joshua continues to work directly with students while leading Northstar's instructional approach and growth.
He holds an M.S. in Applied Mathematics, an M.S. in Data Analytics, a B.S. in Mathematics, and a Graduate Certificate in Applied Statistics. He has 9+ years of experience teaching mathematics, including college and graduate-level instruction.
His teaching experience spans middle school through advanced and college mathematics, alongside curriculum development, educational technology, and remote education.
Expect clear explanations, purposeful practice, and direct communication with families about how your student is progressing.
Our team is growing
Northstar is expanding its tutoring team.
We're bringing on tutors carefully so we can support more students while preserving the individual attention that defines our approach. We're looking for strong mathematics tutors who are patient, dependable, comfortable teaching online, and able to connect with students one-to-one.
