Get in TouchWe built One Step to be the rehab we'd want to send our own family to — small enough to know every client by name, experienced enough to handle the hardest cases, and honest enough to tell you what actually works. — Alastair Mordey, Founder
Who We Are
One Step Rehab is a 14 bed addiction treatment center based in Chiang Mai, Northern Thailand. We are fully licensed by the Thai Ministry of Health. We cater to predominantly international clients, especially from the UK, US, and Australia.
As a small and independent treatment center, we do not believe in the 'production line' approach that some larger rehabs adopt. We are small and we will stay this way so our team can continue to provide the type of care that is necessary for successful long-term recovery.
We offer cutting edge techniques to beat addictive behaviors, with fitness bootcamp, nutritious meals, individual and group counseling, and exciting excursions around Northern Thailand all included in the cost.
In terms of value for money and a no-nonsense approach to addiction treatment, One Step Rehab is hard to beat. We are proud to be transforming addiction treatment in Thailand by putting the client firmly back at the heart of recovery.
Our Philosophy
Our philosophy centres on four core areas of focus that are necessary for any successful journey towards recovery.
Chemical Sobriety
Whatever your addiction, abstinence from those drugs is the basis of recovery.
Connection
The worst thing is to be isolated. Addiction is a disease of isolation. Therefore, recovery cannot be achieved alone.
Emotional Sobriety
Learning how to regulate your emotions is the key to leveraging your full potential in recovery.
Metabolic Health
In order to be mentally healthy it is necessary to recive good nutrition and regular exercise.
At One Step we have created an affordable, high-quality addiction treatment program which guides clients to achieving long lasting sobriety by focusing on these core principles of recovery.
A Typical Day at One Step
Structure is one of the most powerful therapeutic tools we use. Addiction thrives in chaos, irregular sleep, poor nutrition and unstructured time. At One Step, each day is deliberately organised to stabilise the nervous system, rebuild physical strength and create consistent behavioural momentum. The rhythm of the day is steady, purposeful and repeatable — so that discipline becomes normal rather than forced.
Here is an example of a typical day during residential treatment:
Weekends include excursions, structured leisure, family calls and additional reflective work. Over time, the brain begins to associate reward with effort, connection and progress rather than substances or compulsive behaviours. Clients leave not just with insight, but with a lived experience of what stable, structured days feel like — and how to recreate them at home.
We’ll have an honest conversation about whether our programme fits your situation. No sales pitch, no pressure.

Our Treatment Model
Our treatment model is built around our Five Pillars framework which ensures that recovery is addressed comprehensively, and holistically, rather than in isolated fragments. The Five Pillars of Recovery are:
- Medically supervised detox and stabilisation
- Addiction counselling and psychotherapy
- Holistic therapies for addiction such as mindfulness and breathwork
- Nutrition, fitness, and supplementation
- Relapse prevention and aftercare (including family work)
At One Step Rehab, we use only the most evidence-based modalities including CBT, DBT, EMDR, MET and more.
The Team Behind One Step
Our founding team are credited as pioneers of the Thai rehab sector. They have over a century of combined experience running residential treatment centres and have directly shaped many of the treatment approaches now used across the region.
Alastair Mordey was the first to popularise REBT for addiction treatment in Thailand, pioneered the use of outdoor therapeutic programmes for young men in recovery, and has presented at international addiction conferences on topics from kickboxing therapy to motivational interviewing.
When you choose One Step, your treatment is led by people who built this industry — not staff who read about it in a manual.
Accommodation & Facilities

Frequently Asked Questions
Common questions about One Step Rehab, our team, and how we work.
Three things: size, method, and aftercare. We’re small enough (14 clients) that treatment is genuinely individualised. We have our own specific treatment method built on REBT, motivational interviewing, and mindfulness — not a generic programme. And we provide 12 months of online aftercare included in the programme fee, which is unique among Thai rehabs.
One Step was founded by Alastair Mordey and a team with over a century of combined experience in addiction treatment. The founding team pioneered many of the treatment approaches now standard across Thai rehabs, including REBT-based addiction therapy and outdoor therapeutic programmes.
Our programme is built on Cognitive Behavioural Therapy (specifically REBT), Motivational Interviewing, recovery coaching, mindfulness meditation, trauma-informed care (including TRE and Trauma-Focused CBT), physical activity, and structured relapse prevention planning. Every client receives an individualised treatment plan based on their specific needs and situation.
One Step is positioned as mid-range — we invest in clinical quality rather than luxury amenities to keep costs accessible. For current rates, visit our pricing page or contact our admissions team for a confidential discussion about your situation.
We provide 12 months of ongoing online therapy after discharge. This includes weekly Saturday group sessions with alumni and continued access to the counsellors you worked with during treatment. The aftercare is conducted by your primary therapists, so you maintain the relationship you built in-house.
We’re in Mae Rim, a district about 30 minutes north of Chiang Mai city centre and airport. The facility is set among rice paddies with views of the surrounding mountains — a calm, rural setting that removes you from city triggers while still being accessible from Chiang Mai International Airport.
Your journey to One Step Rehab begins with an email or phone call. After an informal chat with our admissions team, you’ll complete a short phone assessment so we can understand your needs and develop an appropriate treatment plan.
