You really can't go wrong with any of the SAs at Manhasset right now. Evelyn, Maryam and Dale have been there the longest, I think. I have been going there for 10 years and I pretty much work with everyone, right now most especially Christine (SM), Lesley (great eye) and Evelyn (sweet, and remembers which scarves I have and which I want), but also the others (especially Maryam if you're into bracelets). If it's busy, any SA will do, really! If you have a question one of the newer SAs can't answer, they'll ask another.
Thanks for sharing your experiences!
