​Brian G. Lengfelder LCPC, CAADC, MISAI, CCJP, SAP, MAC, ACRPS, CSAT/CMAT

"I believe therapy is an intimate form of learning which demands a therapist who is willing to be authentic, compassionate, accepting, and collaborative in the therapeutic process. Every one of my clients deserves to have their story heard from their perspective and be actively engaged in the process of change for improving their wellbeing and learning to live to their full potential."

Brian has been in the addiction/mental health field since 1993. He has been described as a practical, realistic, and down-to-earth therapist who is naturally inquisitive and goal oriented. He brings his warm and light hearted sense of humor to the therapy process, as he has learned that the best way to lead a person toward wellbeing and happiness is to make the psychotherapy process relaxed, enjoyable and non-judgmental.
Brian relies on several different psychotherapy approaches as he doesn't believe in a "one size fits all" approach to psychotherapy. Whenever possible, he uses Evidence-Based Practices (EBP) or Trauma-Informed Care which relies on the thorough, careful and thoughtful uses. He strives to have an immediate impact on his clients so that he can expedite their goals and desires for mental health, happiness and comfort.

Brian specializes in all forms of addiction. He has creative and innovative approaches to help individuals develop management strategies and sustain a fulfilling recovery lifestyle. He has worked in the full range of alcohol, drug and addiction programs from detoxification programs to outpatient services. Brian provides psychotherapy with intimacy disorders and will work with all sex and love addicts, and when possible, their partners and family members. This includes: sex, pornography, compulsive masturbation, cybersex, love and/or relationship addiction. He enthusiastically utilizes Patrick Carnes’ 30 Tasks Model and his primary therapeutic goal is to disrupt and eliminate problem patterns of sexual behavior, while helping his clients regain dignity, self-respect, and the trust of those they love.

Brian believes in the Recovery Management Model and is a certified Advanced Relapse Prevention Specialist, which allows him to provide relapse prevention therapy/interventions to assist clients that struggle with maintaining their recovery from mental illness or other addictive disorders.

Brian provides direct clinical assessment and services for the Federal Government's Department of Transportation (DOT) Substance Abuse Professional Program (SAP), which assists employees who fall under the DOT guidelines with alcohol and/or drug problems to ensure public safety.

Brian is also a professional trainer, speaker and consultant. Brian has presented on mental health and addiction topics at various prestigious venues. He is a consultant to the Illinois Department of Alcohol and Substance Abuse as an independent peer reviewer of agencies for state compliance with federal regulations. Brian serves as a member of the board of directors of the Illinois Certification Board (ICB).
