In addition, I have experience with parenting skills, divorce, co-parenting, grief and loss. I’m passionate about creating and contributing to an environment where people are encouraged to grow to their fullest potential throughout all aspects of their lives. All of us have, at one point, been through difficult circumstances; some devastating. My focus is working collaboratively with those in need, lacking hope and creating a warm, nonjudgmental therapeutic environment as an avenue to heal, grow and achieve positive change.

And others soon to come!
