“I cannot believe how time flies when you are doing something you love! In 1988, Dr. William Schlothober, a renowned psychologist, and I opened the Columbia Addictions Center to our first client. For over 30 years, the goal of the center has always been to provide compassionate and effective outpatient care in an environment free of judgment and blame. We use evidence-based treatment in all of our work, but it is the dedication of each of our therapists and administrative team that really sets us apart.

– Eileen Dewey, LCSW-C, Program Administrator and Clinical Supervisor
