About Us

Training programs for USACO are flawed. Instructors do not slow down for students. It almost feels that they are reading off a prewritten solution. What’s the point in that?

David built USACO Tutor from the ground up because he had a mission: to revolutionize the educational space for these programming classes.

He knows what it’s like to be part of a bad class where progress just isn’t being made.

What makes USACO Tutor different from other programs is our 1:1 customized learning approach. The tutor assesses where you currently are, and what steps you need to take to advance to your target division.

Martin L

Tutor for Bronze - Gold


I hold the good personal values of hard work, morals, and integrity. I have made some accomplishments in the past but I am still humbled. A person could lie cowering in fear or facing it, but in the end, nothing matters.

Stefan D

Tutor for Bronze - Platinum

USACO Platinum

I am Stefan and I am a 20 year old university student who has been involved in USACO and Competitive Programming for 7+ years. As a teacher, I skillfully adapt to each student's needs, using my experience with the USACO competitions both as a contestant and as a teacher in order to accelerate you.
