For exceptional calligraphy, I highly recommend Jan Boyd, Jan Boyd Calligraphy. Located in the Boston area, she works with many New England and New York clients. Her fine artistic work is outstanding and pricing comfortable.
Liz Neumark and Linda Abbey at Great Performances are my go-to people for events large and small. They are a joy to work with and food is exceptional.
For Theater tours for groups visiting New York, I have worked for years with Joe Rosenberg, PhD, of VIP Tours of New York. He is superb.
