Erwin Lass
Clinical Psychologist
Over three decades of compassionate, evidence-based psychological care.
Dedicated to Your
Mental Wellbeing
Erwin Lass has over three decades of experience in Therapeutic Psychology, combining academic rigour with a deeply empathetic approach to patient care.
After obtaining his qualifications from the University of Pretoria — B.A (1981), B.A. (Hons) in Psychology (1983), and M.A in Counselling Psychology (1987) — Erwin registered with the Health Professions Council of South Africa (HPCSA) as a Clinical Psychologist.
His career includes significant military experience in psychology (1986–1997), encompassing senior management, military law, and hostage negotiation. This background provided invaluable exposure to acute stress and trauma, which he has successfully integrated into his clinical practice.
Today, Erwin practises at ZwavelStream Clinic in Pretoria East, specialising in general clinical psychological practice, substance abuse diagnosis and treatment, and dual diagnoses. He remains passionate about understanding and working with the psychological dynamics of human thinking, behaviour, and interpersonal relationships.
