Why do you ask?
If you are looking for someone with whom you can work there are many well trained, experienced coaches and it should not be hard to find someone with whom you can work well. You could look on the ACE site for a list of those near you.
If you need to get quotes for an article or blog you might look to people who have written well on the topic and connect to them.
Just remember fame is not the touchstone of ability or work ethic or knowledge. I am sure we could all name a number of people famous within modern media not for their skills or knowledge.
