Great post Alan. I don't think there exists a more powerful marketing tool than the word-of-mouth recommendation. I like your idea of broadcasting these reviews on multiple channels, including displays in the waiting area. This brings the recommendations to our patients who are not on the Social Web. I saw that you do all of your marketing through social media. I had wondered how this could be adequate considering not all of our patients are on the Social Web. I suppose this is one of the methods to address that.
