In addition to his other duties and hobbies, he masters the flood of calls, mails and interviews that rain in daily, seemingly without problems.
The nice thing is that besides all this, Roger always has time to deal with a problem, to listen to a request or to chat with employees and customers. His team has become incredibly dear to him as he is the same to us! An owner, who puts so much strength and time into his house, transfers all of this to his team and this energy is mentally as well as physically touchable!
