I was lucky enough to be a student of David’s in his Genesis 3 Advanced Hydraulics course. I spent 24 hours trying to absorb more information relating to swimming pool hydraulics and engineering than I have been able to dig up in over ten years of reading and studying almost every publication known to man. The information provided, software provided, and the manner in which it was presented made an extremely complex subject very enjoyable to wrap your mind around. Anyone looking to increase their knowledge of swimming pool design, or needing a firm to provide swimming pool design from simple to the most extreme and complex, look no further. Simply the best and most knowledgeable expert in his field. Top Qualities: Great results, Expert, High Integrity.
