Everyone at DCOL Research is friendly and helpful. They all have a great sense of humor, which really helps you relax. I have participated in several studies with them and the research coordinator I see is awesome. She makes you feel that your health is her top priority. The research doctor is really good too and if you start having problems during the study he will take care of you. This research clinic is like a family, and once you participate in a study, you are just part of the family. R. O.
