Penny Simkin, PT, is a physical therapist who has specialized in childbirth education since 1968. She estimates she has prepared over 9000 women, couples, and siblings for childbirth. She has assisted hundreds of women or couples through childbirth as a doula. She is the author of many books on birth for both parents and professionals.
Through independent study and her work as a birth counselor, she has developed a counseling approach for pregnant survivors of sexual abuse. This work is described in the book, When Survivors Give Birth: Understanding and Healing the Effects of Early Sexual Abuse on the Childbearing Woman, which she co-authored with Phyllis Klaus. Today her practice consists of childbirth education, birth counseling, and labor support, combined with a busy schedule of conferences and workshops.
She co-founded Doulas of North America and The Pacific Association for Labor Support.
