In the first 4 months of working with him he coached me to a 31 min PB in the marathon. I've found him to be very professional and detail oriented especially regarding training specificity and race plans. He also looks at long terms goals and mental preparation. I've developed a lot as an athlete while working with himevixenced by the fact that I've PB'ed at every distance from the 5k to the marathon.
