Dr. Heller, or the Nanny Doctor, as she calls herself (she has a Ph.D. in clinical psychology from the California School of Professional Psychology), is a consultant for an age of anxious parenting, acting as a mediator of sorts for parent and caretaker, at a rate of $200 an hour. She draws from her experiences, both as a mother to two daughters under 3 (she is married to Matt Donnelly, a TV writer), and as a former nanny to clients like the director Stephen Gaghan and his wife, Minnie Mortimer, a fashion designer and socialite.
“I remember her solving a conflict with the kids, who were 5 and 6,” Ms. Mortimer said. “She had them calm down and use their ‘I’ statements. Our little girl said, ‘I don’t feel safe when you throw a Lego at my head.’ Our boy said, ‘I feel that throwing a Lego at your head is the only way to get your attention.’ She treated them with such respect and dignity.”
