Castle Craig Founders

World Class Addiction Treatment

We give patients the therapeutic tools they need to stay abstinent and live fulfilled lives.

Peter & Dr Margaret McCann’s vision for 12 Step Treatment in the UK began in 1981 when Peter McCann established the Life Anew Trust, a charity that promoted effective addiction treatment. They would go on to found two of the leading UK addiction treatment centres.

A Family-Run Addiction Treatment Centre

In 1982 Peter McCann began extensive consultation with rehabilitation clinics in the US in order to develop an effective treatment programme.

In particular, he received enormous support and guidance from the directors of the famous Hazelden centre in Minnesota.

In April 1983 Peter & Margaret Ann founded Clouds House, a non-profit drug & alcohol treatment centre in Wiltshire.

33 Years of Expertise and Over 10,000 Patients Treated

After successfully directing the treatment programme at Clouds for five years, Peter and Margaret Ann moved to Scotland in 1988. Castle Craig was the first treatment centre to bring the 12 step facilitation programme to Scotland.

In the early 1990s, Peter McCann founded the European Addiction Treatment Agency (EATA) which is now the largest membership organisation for the independent drug and alcohol treatment and continuing care (also known as aftercare) sector.

Peter and Margaret Ann have presented at many conferences, written research papers and belong to a number of professional organisations. Dr McCann has served on the Executive of the Medical Council on Alcohol and Peter McCann has been elected a Board Member of the International Council of Alcohol and Addictions.

How Can Castle Craig Help?

How Do I Pay For Rehab?

One concern we sometimes hear from people is how they will fund their rehab treatment. The cost of rehab varies depending on what kind of accommodation you choose. You can pay for treatment at Castle Craig privately, or through medical insurance, and some people receive funding through the NHS.

How Long Is the Rehab Programme?

Residential rehab treatment starts at 4 weeks and can go up to 12+ weeks. Research shows us that the longer you stay in rehab and are part of the residential therapy programme, the longer the likelihood of continued abstinence and stable recovery.

Who Will I Speak to When I Call?

When you call you will reach our Help Centre team who will give you all the information you need to help you decide whether to choose treatment at Castle Craig. Once you have decided that you would like to have a free screening assessment you will be put in touch with our admissions case managers who will guide you through the admissions process.

What Happens at the End of My Treatment?

Castle Craig thoroughly prepares patients before departure by creating a personalised continuing care plan which is formulated following discussions with the medical and therapeutic team. We offer an online continuing care programme which runs for 24 weeks after leaving treatment, in order to ensure a smooth transition back into your everyday life. Patients leaving treatment automatically join our Recovery Club where they can stay connected via our annual reunion, events, online workshops and recovery newsletters.
