Chestnut provides a full range of addiction counseling and treatment for adults. An assessment is required to determine the most appropriate level of treatment for each individual.

Gender-Specific Treatment

Chestnut has separate treatment programs for males and females and offers gender-responsive treatment. Gender-responsive treatment allows men and women to focus on issues specific to their strengths, needs, and barriers. While there is a commonality in issues – relationships, family of origin, parenting, anger, spirituality, dealing with emotions – the discussion of such topics must be provided in a safe environment that is offered in gender-specific groups.

Residential Treatment

Residential services are designed for adults who need more clinical services than our outpatient program can provide. Adults participating in residential treatment live at the treatment facility while participating in day and event treatment and recovery support activities. This level of care is appropriate for people who:

  • need a structured and supportive environment to maintain recovery from addiction; and
  • require more intensive services to help prevent further damage to their physical and emotional health.

Licensed and certified counselors provide quality addiction counseling and treatment services in a comfortable facility. The hallmark of Chestnut’s treatment is the use of research-tested and approved treatment methods combined with the demonstrated effectiveness of self-help programs. While in treatment with Chestnut, residents participate in individual, group and family counseling and receive intensive instruction in life skills such as decision making, stress management, assertiveness, coping styles, relapse prevention, and addiction education. As a supplement to treatment, individuals are expected to participate in self-help groups such as Alcoholics Anonymous (AA), Narcotics Anonymous (NA), Celebrate Recovery or other community support groups several times per week. This helps build a recovery support network in the community which is important for maintaining a recovery-oriented life. Residential treatment also includes 24-hour clinical supervision, access to a staff psychiatrist, access to on-site medical services, catered meals, and recreation facilities.

Each adult has a unique treatment plan to meet his or her specific needs. The length of stay is individually determined and regularly reviewed during the course of treatment.

Following successful discharge from residential treatment, Chestnut’s treatment team will arrange a comprehensive continuing care program. This plan may include involvement in a Chestnut outpatient group or a group in the person's home community. The plan will also include recommendations and contacts for community support groups and referral to assistance programs when appropriate.

Intensive Outpatient (IOP)

Intensive outpatient treatment (IOP) services incorporate most of the components of inpatient treatment, but on an outpatient basis. It requires nine or more hours of counseling each week. This level of care is appropriate for those who are experiencing significant substance abuse problems but are demonstrating a willingness to work toward an addiction free lifestyle while remaining in their home environment. 

IOP uses a small group format, meeting on weekdays or evenings. The length of treatment is individually tailored to the client's unique circumstances. 

Clients explore their addiction through a variety of means:

  • substance abuse education
  • individual and group counseling
  • participation in a variety of self-help groups
  • training in relevant life skills to promote healthy lifestyles

Those who have successfully completed IOP or inpatient treatment often go on to outpatient treatment. The longer a person remains involved with treatment, the greater the likelihood of continued recovery. Chestnut customizes its care to fit the needs of each individual. Individuals are also encouraged to participate in a variety of self-help groups such as Alcoholics Anonymous(AA) or Narcotics Anonymous (NA), Celebrate Recovery or other community support groups.

Medication Assisted Treatment (Suboxone®)

Medication Assisted Treatment (MAT) is designed to help those with a variety of addictions to deal with short term and long term effects of withdrawal. MAT helps clients manage their physical symptoms and reduce cravings while allowing them to focus on their work in treatment necessary for behavioral changes. A combination of medication, counseling, and support helps individuals more successfully overcome opiate dependence such as heroin and pain killers. Our treatment primarily uses Suboxone® in combination with regular doctor appointments and participation in addiction counseling. Chestnut offers MAT at its Granite City, Illinois location. Transportation is available for patients qualifying for MAT who live outside the area. 

Individuals wanting to participate in MAT are required to be in a Chestnut addiction treatment program and cannot be using, abusing, or dependent on alcohol, benzodiazepines, barbiturates, or other sedatives, hypnotic drugs.


Many individuals find it possible to work on their recovery from addiction while living at home. Outpatient services are provided on an individual and/or group basis and are appropriate for people who are struggling with an addiction and are ready to take the necessary steps to learn to abstain from substance usage, are motivated for change, and have a supportive living environment. 

This level of treatment requires one to eight hours of counseling each week. Often times, outpatient counseling is most appropriate for individuals who have successfully completed inpatient or intensive outpatient treatment. Outpatient counseling can help an individual maintain long-term recovery. Individuals are encouraged to continue to participate in a variety of self-help groups such as Alcoholics Anonymous (AA), Narcotics Anonymous (NA), Celebrate Recovery or other community support groups.
