In addition to being an independent Love and Logic facilitator, Lisa is a Certified Positive Discipline Associate. Love and Logic and Positive Discipline teach similar parenting skills and concepts- although the delivery style is different. Both are based on the authoritative or democratic parenting style (Love and Logic calls this a Consultant Parent).
Here are many excellent resource references about the impact of parenting style compiled by Jodie McVittie, MD.
Authoritative parenting (parenting that is both firm and responsive) promotes healthy development and decreases social risks. It is associated with increased academic success, decreased smoking, decreased drinking and less chance of being engaged in violence.

The positive impacts of authoritative parenting hold across cultural, social and racial backgrounds, though in some cultures the negative impact of authoritarian parenting (firm but not responsive) is less.
