What does DRCOG mean after a doctor's name?

It stands for "Diploma of the Royal College of Obstetricians and Gynaecologists," a professional medical association for OB/GYNs & Women's Health specialists in the United Kingdom. However, the "official" abbreviation/post-nominal suffix awarded after certification is "DObst RCOG." A physician/general practitioner would earn this certification if s/he wishes to certify their advanced training and education in obstetrics, gynecology and women's health.

I hope this helps and answers your question.
