Mr. Van Huis’ attention to detail is critical to the study, and at times it feels like he is conducting the study alongside the team! He tracks thorough notes and ensures accurate data reporting in a timely manner. He and his wife are very punctual and have set up the next couple of years for vacations, etc. to work around the study schedule and ensure they are always on the target dates. They are warm and friendly and incredible sweet and easy to work with, making them exemplary volunteers.
