Philosophy of Care

INSynergy is committed to implementing scientific advancements and discoveries in the field of addiction medicine.

Advancements in anti-craving medications for alcohol, opiates, and nicotine, along with Cognitive Behavioral Therapy allow INSynergy to treat persons as outpatients without disrupting busy lifestyles.

INSynergy believes that treatment does not have to be a painful, humiliating, disruptive experience. One doesn't have to 'disappear' for 28 days and have employers, family, friends, wonder what happened.

Treatment is local, practical, highly effective and affordable.
