After attending all the 'Big Name' training courses, this by far has been the best. Jeff is not only taught & demonstrated how, but also providing engineering & education that supporten his theories on overall areas of concrete countertop manufacturing. I really enjoyed getting all the information from an independent source. The CCI does not sell products, just needed information to be successful in this industry. I highly recommend this course & CCI to anyone making concrete countertops. Thanks for everything!
