John has been creating careers since he was a teenager. At age 17, he and a few friends started their own high school in Orange, New Jersey called Changes, Inc. In his teens he forged a successful career as a concert cellist and prize-winning composer. At 15 he was recipient of the 1969 BMI Awards to Student Composers, then their youngest award recipient ever; his musical score for Aeschylus’s “Prometheus Bound” (written at age 13) was performed at the amphitheater in Epidaurus, Greece, where the play was originally premiered.

His diverse career has made him a thought leader in several different industries. In 1986 John founded and wrote for Solstice, a journal on health and environmental issues; his series on the climate crisis (yes, he was writing about this back in the eighties) was selected for national reprint in Utne Reader. During the nineties he built a multimillion-dollar sales/distribution organization of over 100,000 people. He was cofounder and senior editor of the legendary journal Upline and editor in chief of Networking Times.

He is married to Ana Gabriel Mann, his coauthor for THE GO-GIVER MARRIAGE, and considers himself the luckiest mann in the world. You can visit him at www.johndavidmann.com.

Ana Gabriel Mann, M.A., holds a Master’s degree in clinical psychology and dance-movement therapy from Antioch New England, where she specialized in working with adults and family therapy. She went on to train and work with renowned Israeli-born therapist Dr. Ruth Holt, a marriage and family specialist who taught couples to identify their patterns of dysfunction and cultivate “love maps” based on Dr. John Gottman’s landmark research. Together they led a highly successful series of therapy groups that gave couples a window into the dynamics of the other marriages in the room.

Following her work with Holt, Ana served as clinical director for a New England–based program providing county-wide therapy, education, and services for family members caring for individuals with Alzheimer’s disease; and as adjunct faculty and student trainer for Antioch New England, utilizing movement therapy to draw on long-term memory in individuals with Alzheimer’s disease to facilitate emotional connection and wholeness. In 1984 she cofounded the New England Institute for Integrative Acupressure, New England’s first college of Chinese medicine, where she co-led programs through 1997.

For the past two decades Ana has worked primarily as a corporate consultant, speaker, trainer, and business coach in both profit and nonprofit sectors. In addition to coaching and teaching the 5 Secrets to Lasting Love, she is the creator and lead facilitator of the Go-Giver Marriage Coaches training program.

She is married to John David Mann, her coauthor for “The Go-Giver Marriage.”
