Plum Parenting opened in 2007 and by 2015 over 500 families in the Wellington region and more elsewhere in New Zealand and overseas, had benefited. From 2009 to 2012 Plum Parenting was based at the Plum Garden Parenting Centre in Brooklyn, Wellington (see slideshow below). During this time, Mary facilitated playgroups with an emphasis on parent education. In 2012 Mary closed Plum Garden and embarked on a two-year road trip around New Zealand in response to requests from parents and schools, to offer lectures and mentoring in their communities.
Mary has now re-established her practice in Mount Victoria, Wellington with a focus on individual parent mentoring and is creating an online parenting course based on her work.
