Marcus Joseph is the Clinical Director of Maplewood Treatment Solutions and a behavioral health leader specializing in substance use disorder treatment across the full continuum of care. He is a Licensed Associate Marriage and Family Therapist (LAMFT), Licensed Clinical Alcohol and Drug Counselor (LCADC) and Certified Clinical Supervisor (CCS), and he reviews the clinical therapy content on this website.
Education and Clinical Background
Marcus holds a Master’s degree in Marriage and Family Therapy and a Bachelor’s degree in Political Science and Psychology. That combination lets him look at addiction through both a clinical and a sociopolitical lens: as something that affects an individual, a family system and a community at the same time.
As a licensed alcohol and drug counselor and marriage and family therapist, he works with the whole system around a person in recovery, not only the substance use itself.
Clinical Approach
Marcus blends several evidence-based approaches to improve engagement in treatment and support long-term recovery:
Systemic
Looks at how family relationships and patterns shape substance use and recovery. Learn more about family therapy at Maplewood.
Trauma-Informed
Recognizes the role past trauma often plays in addiction and builds care around safety and trust. See our trauma-informed care.
Client-Centered
Builds each treatment plan around the person’s own goals, strengths and circumstances, starting in individual therapy.
Narrative
Helps clients separate who they are from the problem and rewrite the story they tell about their lives and recovery.
Leadership and Advocacy
Marcus brings years of progressive leadership experience in behavioral health. Before joining Maplewood, he led multi-site operations as Regional Director of an outpatient treatment organization.
He is also committed to advocacy as Chair of the Health Subcommittee for the Philadelphia Reentry Coalition, which supports people returning to the community after incarceration.
As Clinical Director, Marcus oversees clinical programming and service delivery at Maplewood. He works to create an environment where both clients and clinicians are supported, with an emphasis on individualized care, clinical excellence and sustainable recovery.
