I signed up with Amerasia just before r2 deadlines. I initially signed up for one school but added another two as I was so impressed with the service on the first one. I couldn't find much information on Jeremy beforehand but he seemed to have the right background to help me.
What I liked about the process is that right from the start Jeremy put in the effort to get to know me so that I could emphasize my salient strengths to the adcom. I liked how we worked together to brainstorm answers to all the questions together so that I provided a strong coherant application (and not just strong answers to individual questions).
I found writing essays extremely uncomfortable and I did my best to pull myself out of my comfort zone and reveal as much as I could about myself in a way I thought would impress adcoms. Jeremy had no hesitation correcting me when I sounded naive, immature etc and was generally sensitive to nuances that would not show me in the best light. Jeremy was extremely prompt with all edits, I believe all edits were same day or next day. He even chased me up when I was slow to reply so that I would be in no danger of missing deadlines. Even through the birth of his baby he helped suggested edits from the hospital - now that is total committment.
I was interviewed at all the schools he helped me with and admitted to two. Overall I highly recommend Jeremy.
