Mark Chandaue is one of the nicest and most creative people in magic.  He has been in and around the magic community for decades and would help anyone.  He started his career as a coin magician and was highly regarded as one of the top coin magicians on the planet.

However, after a few years he pivoted into mentalism.  He is now considered one of the best and most creative magicians and mentalists loved today.  He has literally written the book when it comes to practical and commercial mentalism.  His mentalism books are a must read for serious students of this art form.
