”Together with Dr Castol, I managed to find answers to questions I couldn’t answer for a long time. The way he asks his questions, with patience, without pushing my answer in a certain direction, makes me find my answers myself. I can advice Dr Castol to everyone who is looking for the right answers, but just needs the right person to walk with you on your own path..”
