"I am lucky to be doing what I love. Most important to me, and what puts a smile on my face, are individuals looking for assistance in order to achieve their goals. Whether that is improving their lives, getting unleashed from a substance they are sick of, improving their relationships, jobs, or parenting, I am lucky to be doing what I love!"
