Dr Koop has always been a concerned, caring doctor that listens and answers questions clearly and doesn't make me feel that I wouldn't understand the answer so why go into detail. My son who never liked going to doctors and my daughter-in-law who has been dissatisfied with doctors she's gone to, now has Dr. Koop as their primary doctor.
