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.

Eric also has a passion for music and can often be found leading jam sessions on his guitar at our program houses.
