""I attended the course Thermography, online, completing the three modules. they are didactic and give great comprehensiveness of learning. I did more, I went to Portugal in Nisa, I was receved by Dr Valdez and his family the warmest possible. During the hours I was with him, he gave me a lesson in 4hours with their equipment and showing with no restrictions your image files and library. I emphasize that it is a very correct person, with a lot of knowledge and a wonderful family. Thanks Dr Valdez, know I´m your student and friend in Brazil Darci Schiavon Abreu Limeira-SP ""
