Dr Warren Hern


In 1972, Dr. Warren Hern, M.D., M.P.H., Ph.D. returned home to Colorado to serve as a consultant for national and international family planning programs. In 1973, following the Roe vs. Wade decision legalizing abortion, he was asked to help found Colorado’s first free-standing nonprofit abortion clinic. Since November 1973, Dr. Hern has been providing abortion services full-time in Colorado. In January 1975, he opened his private medical practice, Boulder Abortion Clinic.

Since 1971, Dr. Hern has been the author of dozens of medical journal articles, editorials, and many other publications concerning abortion and other aspects of human fertility. In 1988, he received his Ph.D. in Epidemiology from the University of North Carolina School of Public Health. He is the author of Abortion Practice, the first and only single-author medical textbook concerning abortion, which was first published in 1984 and which remains in print. In 2002, Dr. Hern received the Christopher Tietze Humanitarian Award from the National Abortion Federation for his advancement of quality care in abortion services.

Later in 2002, he also received the Carl S. Schulz Award from the Population, Family Planning and Reproductive Health Section of the American Public Health Association for his scientific contributions and defense of reproductive freedom. The National Organization has previously honored him for Women, the National Abortion Rights Action League, and the Colorado Coalition for Choice, the Colorado Women’s Political Caucus, and, in 2003, by Women’s Choice, of which he was the founding Medical Director in November 1973.
