Dirk has trained course my son and me at the PADI and OWD in Kas, Turkey. We had an intensive program with dives, learning and control tests and have made together good progress. While not everything right off the bat we have succeeded of course but Dirk has patiently encouraged us and asked. We felt safe in the underwater world with it and the instruction above and under water was very easy to understand. Dirk is a very good diver and instructor. We appreciated the time together and enjoyed! It has been fun!
