Welcome to Co-parenting Coach
Welcome !
Every family is unique. Your support should be, too.
Coaching sessions available in person in the Nyon region, or remotely via video.
Are you a parent who sometimes feels a little overwhelmed? You’re not alone.
Whether you’re feeling uncertain, going through a difficult time, or simply looking for practical and gentle tools, you’re in the right place.
I’m Sonia Lieberherr-Diehl, a bilingual (French/English) parenting and co-parenting coach with over
20 years of experience and more than 3,000 hours of coaching with families from all walks of life — whether traditional, single-parent, blended, or in the midst of transition.
I support you with care and clarity to restore calm and harmony to your family life, whether you have toddlers, school-aged children, or teenagers.
I also help separating or divorcing parents build a clear and peaceful parenting consensus, in the best interest of their children and without exhausting themselves in lengthy and costly legal battles.
