What I do
Five practice areas, one consultant. Each engagement begins with a free consultation; from there we agree on scope and a working cadence. I do not run a roster larger than I can teach personally.

I grew up across three countries — India, Poland, and South Korea — before coming to the US for college. By the time I graduated from KIS Pangyo, I had already spent years teaching classmates through subjects they found difficult. What started as volunteer tutoring in middle school had become the work I most wanted to do.
At St. Lawrence I followed the pre-med track — Dean's List, magna cum laude, immunology research at UVA. On paper I had a plan. Then I worked for a year and a half, came back to Korea for military service, and somewhere in that stretch the certainty quietly dissolved. I had been heading toward a destination I'd inherited rather than one I'd arrived at by genuinely asking who I was or what I wanted to build.
That pivot is why I now work the way I do. Authent Ed is one consultant — me — and a small roster of students I work with closely over time. Not a task manager: someone you can think out loud with. That is the difference I built this practice to provide.
