Our Team


Cornerstones of Maine is the result of a labour of love for our two founders, Josh and Jake. It is independently owned by them and was established on the foundation of their desire to create a young adult transition program that is based on mental health research and experience. Not only are they the founders, they are also part of our core clinical staff.
