Thanks Arfy, I did find him on this site -- but the site also says that it posts doctors who pay a fee which, while honest, doesn't make this site's endorsement particularly compelling. The endorsement read like an ad -- has Pat met with a number of Gillespie's clients to determine the quality of his work? It doesn't appear so.
As regards your other suggestions, good advice and I do plan to try and meet with some actual clients.
