Joel

Manager

“Alcohol had slowly taken over my life—my work, my family, my self-respect. Therapy helped me understand that drinking wasn’t my real problem; it was how I was coping with stress and pain. With counseling and support, I learned healthier ways to deal with life. Today, I’m sober, present, and finally in control again.”
