Hi Christine,
I did a search for Don Gray using the search tool (upper RH corner) and numerous threads came up, some commenting on Don's service.
I personally haven't used him or have I had clients use his services to my knowledge. I will ask my client base if they have though and let you know if someone in my network has experience with him.
I hope that helps,
Lucas Fausak
