MANY PEOPLE in the field of genetics are mourning the murder of Dr. George Tiller as the loss of a personal friend. I'm one of them. I first met George in 1987 at a conference of the National Society of Genetic Counselors, where I was executive director for 18 years until 2005. He and his incredibly loyal staff - whom he treated with great generosity - had developed a procedure that provided excellent medical care but also respect and emotional support to the women who came to him for help.
