She was born to John Cleve Munger and Nancy Allen Munger at St. Joseph Hospital, Pontiac, Michigan. In 1968, Evans created and edited an alternative newspaper, The Zeitgeist, and poetry magazine, Cinnamon Crust. Shortly after completing studies at Royal Oak's Kimball High School in 1969, Evans entered Justin Morrill College at Michigan State University as an Art and English major. She met David Evans in 1969 and married him in 1970. Following David's graduation in 1970 from MSU, the couple returned to Oakland County.

While studying at Wayne State University in early 1971, she embraced faith in Jesus Christ. Between 1971 and 1974, Evans and her husband founded and managed Predmore Farm, a residential Christian community located in Oakland Charter Township, now the centennial site of Cranberry Lake Farm, a 207-acre park where members of the Detroit Symphony Orchestra perform an annual summer concert. After giving birth to her first child at home on the farm in 1972, Evans became a childbirth educator and breastfeeding advisor, later working as one of the nation’s first paid lactation consultants through her employment with Dr. David Gustafson at William Beaumont Hospital in Royal Oak.

Until her retirement from the field in 2003, she remained involved in health education and midwifery advocacy. Evans taught classes as a part-time instructor at Lansing Community College (1978-1981) and the University of Nebraska-Lincoln (1984-1988). She also served in Michigan as state coordinator of the International Childbirth Education Association (1979-1981) and member of the Department of Health’s Task Force on Perinatal Education (1980-1981); in Nebraska as member of the Lincoln-Lancaster Health Department Task Force on Children and Youth, Teen Pregnancy Subcommittee (1983-1984) and the State of Nebraska Breastfeeding Promotion Task Force (1988-1990); in Georgia as member of the DeKalb County Disabilities Council (1991-1993) and president of Atlanta Bethany Christian Services (1991-1993); and in Texas as board member and chair of the State of Texas Midwifery Board (1998-2003).

In 1978, she developed and taught Parents Preparing in Christ (PPC), a class series for expectant Christian couples in Michigan (1978-1981) and Nebraska (1982-1990). Immediately after her graduation in 1983 from the University of Nebraska-Lincoln (BA, University Studies in Family Wellness and Reproductive Health), Evans wrote her first non-fiction book, The Complete Guide to Childbirth, based on her research for the PPC curriculum. Following the book’s publication in 1986, she has continued to author many additional works, including Beauty and the Best, Kindred Hearts, and Blessing Your Husband.

In 1988 and 1989, Evans was a finalist for the Evangelical Christian Publishers Association (ECPA) Gold Medallion Awards in the Marriage and Family (The Mystery of Womanhood) and Inspirational (Fragrant Offerings) categories, as well as for Christianity Today’s 1990 Critics’ Choice and Reader’s Choice Awards (Without Moral Limits). Reviews of her books have appeared in The Annals of Pharmacotherapy, The Austin American Statesman, Christian Herald, First Things, The Lincoln Journal, Marriage & Family Living, Publishers Weekly, Religion & Society, Southwestern Journal of Theology, The Atlanta Journal-Constitution, and Today’s Christian Woman. From 1989-1996, Evans served as contributing editor of Christian Parenting Today.

Since 1986, Evans has appeared as a featured guest on over five hundred radio and television interviews. Her participation in the panel discussion on reproductive technology and embryonic stem cell research (taped on March 7, 1990 by Family Christian Broadcasting Network—KFCB, Concord, California) was awarded the 1990 Angel Award for Best Network Documentary.

Her seventh book, Without Moral Limits, resulted in invitations for Evans to serve as a member of the Colloquium on Medical Ethics held at Trinity Evangelical Divinity School (1989) and the Christianity Today Institute Forum on Birth Control (1991), with subsequent statements and articles published in the New England Journal of Medicine (1990) and Christianity Today (1991). She was a signatory of the statement, “On human embryos and medical research: an appeal for ethically responsible science and public policy."

Evans relocated to Texas in 1993, where she resides with her husband in Austin near their four grown children and four grandchildren. In addition to working on her next book, Evans serves her local church community as a small group leader and spiritual director. As a founding board member of the Firelight Foundation, she supports and advocates for the needs and rights of children affected by HIV/AIDS in Sub-Saharan Africa.
