  • In-vivo exposure which allows clients to confront and regulate emotional response to workplace triggers in real time
  • Cognitive Behavioural Therapy (CBT) to assist in developing helpful thought patterns and healthy behaviours in recovery
  • Dialectical Behavioural Therapy (DBT) for developing the skills needed to manage emotions and relationships, practice mindfulness, and survive crises
  • Cognitive Processing Therapy (CPT) to help clients to process their beliefs about a traumatic event they have experienced
  • Individual psychotherapy for an empathetic and safe space to discuss personal recovery concerns and develop treatment goals
  • Group therapy to provide opportunities for peer support and professionally guided emotional processing
  • Psychoeducational sessions to help you understand yourself, trauma and the nature of addiction
  • Relapse prevention groups for identifying substance use patterns and relapse warning signs, and to develop a long-term recovery plan

Start the day with a healthy, freshly-prepared breakfast. Then you’ll set your intentions with self-reflection, before attending an educational lecture about distress tolerance. Afterwards, you’ll get moving with a workout in our fitness centre, relax with a hot yoga class, or even attend a boot camp session.



After a delicious lunch, learn how the mind-body connection affects trauma recovery. Then, attend a one-on-one therapy session to learn how to cope with triggers.



In the evening, participate in a specialized, trauma-centred peer support group focused on symptoms management, emotional processing, or returning to work. After meditating, enjoy dinner with fellow clients and an evening walk.
