I had Amy about a month ago...good massage, but not as skilled as Shirley. She's somewhat heavier, and occasionally concentrated her weight to one knee and pinched skin (ouch). Hands aren't quite as strong as Shirley's either. Shirley seems to have a system and a plan for hitting all parts of your body and it really flows in rhythm. Amy's was more of a meandering approach.
But, all in all, a good massage. However, I will request Shirley on each of my visits. She's just much more skilled.
