I received my Master's degree from Mills College in 2009 in a Masters/Doctoral combo Educational Leadership program, while raising three little girls, who are now young adults.  "Nature Lady" is one of my nicknames, for my love of nature and desire to reconnect to humanity and the universe, in order to land daily in a peaceful, balanced place.  I also enjoy learning from our youth, and supporting people with generational and other types of traumas.  Sharing my experiences with the world and being an example of the change I want to see in the world is my goal.
