About a year or so ago, I had the opportunity to attend a speaking engagement -- topic was change & speaker was from vitalsmarts.com. The book the speaker referred to was "Influencer: The Power to Change Anything" (this is just one of their books)
Unfortunately I have no contacts at vitalsmarts. If anyone does, or if anyone has read one of their books (please visit their site for books/topics/speakers), they are definitely worth considering for one of our meetings. I don't know if their presentation could be interactive (at the event I attended it was not), but it was definitely engaging.
Thank you.....Lois Frank
