Our Team



Kristina is an author, artist and coach. Kristina’s second co-authored book, Positive Discipline for Today’s Busy (& Overwhelmed) Parent, was published by Harmony Books NYC, in September 2018.  Her first co-authored book, 101 Days to Make a Change (Crown House UK 2011) was nominated at the 2012 People's Book Prize in two categories, Best Non-Fiction and Best Debut Writer.  She has released three albums of critically acclaimed music, and has created several music films to support her work.  Early in her career, Kristina worked as an actor and TV presenter, and has continued as a filmmaker to produce communications pieces. She is a prolific voice over artist working across television, film and corporate media. She is a highly sought after coach specializing in leadership, communication and personal impact, and has developed and run training for adults for over 20 years across Europe and the US.  

With many different talents and qualifications, Kristina feels uniquely positioned to advocate and guide her audience, readers and clients away from fragmentation and towards cohesion: By striving to be your authentic self, there is no need to 'change hats' depending on the situation.  She believes that with the right support this mind-set can be developed and maintained with balance and harmony. 



In Progress



Muriel has worked as a teacher for the last 14 years in Belgium, Ghana, Kenya and the United Kingdom. She discovered Positive Discipline soon after her first son was born. She now uses Positive Discipline at home, in her classes, and as a co-facilitator of parent workshops. In Kenya, as well as teaching, Muriel was involved in supporting two NGOs: She established the nonprofit IDAY network in East Africa. IDAY-International is a network of civil society organisations committed to basic education for all in Africa. 

She also facilitated training sessions on "basics of classroom teaching" to more than 100 untrained teachers from the Kangemi slums, using that opportunity to give the teachers a few Positive Discipline tools.

Muriel lives in London with her husband and three children.



As a child of an army doctor Aerian experienced many different countries and cultures from an early age and continued her travels with her own family in South Africa, USA and Hong Kong.

Since returning to the UK twenty years ago, Aerian has worked at the American School in London (ASL) as the lower school (primary school) counsellor.  A great deal of her work at ASL has involved working very closely with children and their families.  

It was at ASL just over seven years ago that she was introduced to Positive Discipline.  It immediately resonated with the way she worked and with the way she had been raising her own two children.  Positive Discipline has formed the essential basis for both her work and family approach ever since.

Aerian is grandmother to two [and counting] gorgeous toddlers!
