I have been doing masonry work for about 8 years and have never been able to find a way to become certified other than joining e union. I came across Charles website and decided to give him a call. Glad I did not only did Charles send out my course within a timely manner but he kept in touch with me. Anytime I had a question all I had to do is call or email. He is 100% committed to helping people learn this trade. It's hard being I. The trades to find people to train you due to job security anyone in The trades has had to deal with that. Not with Charles he's there to help. I strongly advise people to purchase is course.
