I found Sean when looking for a running coach in NYC. I picked Sean because of his PRs: 4:3X mile and 15:XX 5K. I strongly believe having a good running background is fundamental for being a good coach, and it showed. In half a year, my 5K PR dropped from 21 to 17. I recommend Sean because he's able to help improve both your training plan as well as running technique during the 1 on 1 sessions.
