Alastair Mordey

Alastair Mordey is the Program Director here at One Step Rehab in Thailand. He has over twenty years of experience as an addictions professional. In the early 2000’s he worked in community drug and alcohol services in North London. In 2010, he founded The Cabin Chiang Mai based in Northern Thailand, which became one of the largest rehabs in the world.

As a founder and global clinical lead of The Cabin Group, Alastair wrote and designed The Edge program which became a blueprint for other treatment centers in the Thai rehab sector. The Edge program specifically used Muay Thai and Triathlon training regimens to heal young men of their addictions.

Since then, Alastair has founded numerous other behavioral health companies such as Elevate Health and Alpha Sober Living. Alastair and his wife Fihn founded One Step Thailand to address challenges faced by addicted people living in the post-Covid world, including more mental and emotional health disorders as well as financial limitations. One Step’s mission is to provide the highest quality affordable addiction treatment in the world.

Addiction Professionals – Advanced Practitioner

Alastair is also a well-known speaker and writer on addiction issues. As one of the most prominent addiction professionals globally, he features regularly in international press, and as a keynote speaker on the addiction treatment conference circuit.

Our founders and lead clinicians have overseen the treatment of more than 5,000 people, with some of the highest success rates in the industry. Don’t trust your recovery, or that of a loved one to inexperienced treatment professionals or centers with no pedigree.



Psychotherapeutic treatment for addiction at One Step is approached using 3 equally effective therapies;

CBT (cognitive-behavioral therapy)

CBT is based on social learning theory and concentrates on exploring new ways of thinking and behaving which reduce the severity of unmanageable feelings.

12-step facilitation therapy (TSF)

TSF is based on the 12 steps of Alcoholics Anonymous but adapted for an formal setting like a rehab. Its main aim is to familiarise the client with the support networks of 12 step fellowships before they return to their home community.

MET (motivational enhancement therapy)

MET (sometimes known as MI, or Motivational Interviewing) is based on meeting the client ‘where they’re at’ and ‘rolling with the resistance’ that addicted people often have when it comes to giving up their drug of choice. This is normal, and skilled therapists should be able to ‘invite’ and ‘motivate’ addicted people into a recovery lifestyle rather than ‘forcing it’.

“During the first week I could barely run round the villas, but by the end I was doing three rounds of Muay Thai”
