Thank you greatly for the fantastic weekend filled with enormous amounts of information regarding air sampling as a building biologist. I found the information interesting, useful, relevant, professionally presented and despite the complex topics of chemical and biological hazards and testing methods were easy to understand. Raphael and Nicole shared a wealth of knowledge with us, were very friendly and approachable, and made the intensive not only interesting and valuable, but also fun. No questions remained unanswered, practical parts were explained and demonstrated well and as simple as possible. Despite large numbers, every participant got hands-on experience with the latest equipment which was an invaluable experience. Well worth the trip from Queensland and highly recommendable!
