“Recovery is much more than not picking up a drink or drug one day at a time or learning to avoid triggers that prompt relapse.  The point of recovery is stepping into the truth of who you are.  Twelve-step and other programs create necessary structure and foundation for that exploration and empower each person to find his or her own way.  My expertise is helping people get more comfortable and confident in their ability to express their true selves”
