Daniel Lettenberger-Klein, MS, LMFT,
Executive Director

Daniel Lettenberger-KleinDaniel Lettenberger-Klein, MS, LMFT, is Executive Director of RiverMend Health Center of Atlanta, where he oversees business operations, recovery programming and clinical processes related to patient care.

Daniel received his Bachelor of Science in Psychology from Bradley University and his Master of Science in Marriage and Family Therapy from Purdue University. He has worked in every level of substance abuse treatment as a substance abuse counselor, family therapist and counseling supervisor. His responsibilities included conducting biopsychosocial assessments, creating individualized treatment plans and providing individual, couple, family, group and multifamily group therapy. As a supervisor, he oversaw hiring, provided case consultation and managed staff.

In 2012, he started his own practice, offering individual, couple and family therapy with a specialization in addiction and trauma. He is certified to provide EMDR (Eye Movement Desensitization and Reprocessing) to help patients overcome trauma. A certified instructor for the Crisis Prevention Institute (CPI), he also trains employees at healthcare facilities to prevent, identify, diffuse and manage disruptive behavior and aggression.

Before joining RiverMend Health Center, he served as the executive and clinical director, and later regional director, for a detox center with locations in three states. In that role, he oversaw the clinical and admissions departments, worked closely with a multidisciplinary team to coordinate patient care, implemented performance improvement initiatives, ensured compliance with Joint Commission accreditation requirements and worked with leadership teams.

Drawn to help those with addictive disorders because of his own family’s history of addiction struggles, Daniel’s goals are to ensure the admissions process is thorough and inviting and to make sure patients receive individualized, integrated care. He is committed to including families in the recovery process, allowing them to provide important support for their loved one and facilitate their own healing.
