Sibyl Pien

(Clinical psychologist and Owner)
I’ve been working in care and treatment of addicts since 1995. For several years, I have been working in the regular care environment in Belgium. In 2007 however, I switched to the private care 12 Steps Minnesota Model. For more than 4 years, I have combined both systems; my own clients and my work in foreign 12 Steps clinics.
I started Affect2u in 2012, my way to develop my passion and care for the recovery of addicts.
People often ask me whether this job is not too heavy or too difficult, or whether I am not tired of it after all those years … I can only answer “No” to that question! It is just awesome to work with people suffering from addiction in their process of recovery. For me, addicts choosing to become “clean and sober”, are the most creative and intelligent people I know.
I am grateful, because I can help to support a recovery process of people who are going through hell, families and partners that are suffering from grief, anger and shame because of the addiction… leading those people back to a sober life, a grateful and peaceful life without any addiction or use of medication, and helping them repairing their relation with family and partners.
This process isn’t an easy one. In my opinion, addiction is one of the most complex and destructive illnesses that exist, with many different faces, making you believe there is no addiction at all, making you compare with “the drunk man under the bridge who has lost everything” … But nothing is further from the truth. Addiction can affect everyone, even and certainly the average and higher social class.
This passion and care taking is my vision and my mission, to guide every day again and again a person with addiction to the “sky”, instead of letting them skid to a hell of destruction, grief and death …

Helena Mermans

(Doctor/NLP coaching)
Works as a general practitioner since 1992. She has been exploring NLP, family structures and Ericksonian hypnosis. This type of hypnosis is a strong way to get in direct contact with the extreme potential of our subconscious. It offers stunning possibilities to discover your own resources, to get rid of old burdens and to become the person you really want to be. As a mother of an addict herself, she has learned how to deal with codependency and knows the profound value of the 12 Steps treatment programme. She facilitates weekly sessions related to themes that help you to let go of old habits and she teaches tools to learn how to find and to use your own resources.

As peer counselor and addiction expert in national and international addiction clinics I have worked with lots of different target groups. These working experiences have taught me that the recovery of clients does not only happen through therapy, but more so through attention, love and proper guidance within the aspects of the holistic model.

As counselor I am a pillar and a mirror for those I work with. Honest, open and straightforward. That is the best description of myself. The process of awareness, also the goal of the 12-step program, is in my opinion the key to a complete, loving and happy life. To live in harmony with yourself and existence.    

The 12-step Minnesota model that Affect2U uses to treat clients and guide them back into society, is the treatment method that has convinced me that recovery from a (long term) addiction is possible. Myself as well as thousands of addicts around the world benefit from this on a daily basis. I have the utmost gratitude that I can contribute to this in my job.
