David and I worked together while he was responsible for KNX Association. Those were the early years of the Association in Spain and his management was key to increase the number of activities during that period of time. This was very appreciated by the associate members.
David has remarkable social skills, a communicative behavior and is an open-minded person that helps him in finding the best solution, either with customers or suppliers. Also his enthusiastic and proactive behavior makes him a joy to work with. The above skills, together with his technical knowledge and his capacity to lead cooperative work, make him worth my most sincere recommendation for any project.
