RootED Restorative & Community Support Mentor

I’m originally from Brooklyn, NYC. Moved to Portland Maine in 2005 off and on until 2010. Then I moved to Rockland Maine in 2015, where I called home for the last six years. Recently obtained my Bachelor’s Degree in Practical Theology from Faith Bible College International in Charleston Maine and am now pursuing my graduate degree in the same field. I came to Tree Street because I love to be a part of an organization that is actively engaging its community. Growing up in the inner city you see many challenges that young people face. Challenges that they could overcome if everyone came together and did their part. There is an old African proverb that says “It takes a village to raise a child.”
