For over four decades, Chestnut Health Systems has provided a full continuum of addiction counseling and treatment services for adults, 18 and older, that includes outpatient, intensive outpatient, and residential programs. Services vary across our multiple locations in Illinois including Belleville, Bloomington and Granite City.

Our clinically-licensed and certified counselors care about our clients and are committed to helping them achieve recovery and learning how to sustain a recovery-oriented life. We believe that alcohol and drug addiction and mental illness are treatable yet chronic health problems. Many individuals dealing with alcohol and drug addiction also have a co-occurring mental health issue. Our research tested and approved clinical programs address both addiction and mental illness in order to help adults achieve recovery. We believe that individuals should attend addiction treatment in the least restrictive environment possible, which is determined by an assessment.

  • An individual treatment plan is developed for each adult to work on his or her goals
  • Length of stay in any service is determined by individual situations, needs, and progress in treatment
  • Addiction and mental health issues are both addressed during treatment with psychiatric consultation and treatment with a staff psychiatrist available
  • Family programs are available for supportive individuals in the adult’s life
  • Onsite medical treatment is available as needed
  • Participation in self-help and support groups is encouraged for each adult as an addition to any level of addiction treatment


Finding help for an alcohol or drug addiction can seem confusing and cause stress for anyone; however, Chestnut’s dedicated staff will help you through the whole process. Chestnut’s comprehensive adult assessment is the first step in determining what treatment, if any, is needed. The assessment takes into account all aspects of one’s life to ensure his or her exact needs are addressed. An assessment includes an individual diagnostic test, a consultation with a counselor, a urine drug screening, collection and review of relevant medical, legal, mental health and previous treatment records, and a physical screening and assessment for detoxification. 

The assessment allows us to learn about the whole person and determines what type of addiction or mental health treatment is appropriate. After the assessment, a counselor will work with the adult to get him or her enrolled in treatment. Adult assessments are available at our BellevilleBloomington and Granite City Illinois facilities.

Medically Monitored Detox

Persons experiencing withdrawal from alcohol, abuse of prescribed medications, heroin and other street drugs meeting our admission criteria can safely be detoxified at one of our crisis residential units in Bloomington or Granite City, Illinois. 

Chestnut Health Systems provides 24-hour short term supervised care for persons aged 18 years and older experiencing withdrawal from most substances that do not require acute hospitalization. Admission to our Detox unit is voluntary. We accept only those individuals who choose to come to the unit. The facility is not prepared to work with persons who are experiencing serious medical problems or complications. The unit is staffed with nurses and behavioral technicians but it is not a hospital.

Persons may refer themselves for crisis/detox stabilization services or may be referred by hospitals, police departments, mental health agencies, social service agencies, and families.

Length of stay depends on withdrawal symptoms. During their stay on the unit, clients spend time in groups that meet six or more times each day. The groups provide education on topics helpful for persons in detox/recovery and clients are encouraged to attend and to participate actively.

Chestnut will provide the safe and supportive environment conducive to achieving stability to live a life free of substances.

The Medically Monitored Detox program has the following components:

  • Phone Screening: Clients can call and do a phone screening that will take about 15 minutes to determine the need for a face to face assessment and the possibility of admission to the Crisis Residential Unit (CRU)
  • Walk-In Detoxification Assessment: Individuals experiencing withdrawal or in need of medically monitored detoxification can meet with staff to determine whether a stay in the CRU would be helpful and appropriate
  • Medically Monitored Detox Services: Clients experiencing withdrawal from alcohol or other mood-altering drugs meeting our admission criteria can safely be detoxified on the CRU. Our Detox unit is staffed 24 hours per day with trained nurses, medical assistants and counselors to provide safety and stability during this time of withdrawal

DUI Evaluations

In Illinois, anyone arrested for driving under the influence of alcohol and/or other drugs (DUI) must undergo an alcohol and drug evaluation before sentencing can occur for the DUI offense, or restricted or full driving privileges can be granted by the Office of the Secretary of State.

The purpose of the evaluation is to determine the extent of the defendant’s alcohol and/or drug use and its associated risk to current or future public safety. The following areas are reviewed: the defendant’s driving history, chemical test results (blood alcohol content), Objective Test score and category, and the interview with an evaluator.

When the evaluation is completed, a classification and a recommendation will be determined by the evaluator and recorded on the Alcohol and Drug Uniform Report form for the Court or the Office of the Secretary of State. This form will then be sent to the Court or given to the defendant to take to the Office of the Secretary of State for the driver’s license hearing.

DUI evaluations are offered by appointment at our Bloomington and Granite City Illinois facilities.

Services Levels

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.

Family Involvement

Chestnut Health Systems strongly encourages families to participate in their loved one’s treatment experience. Substance usage affects the entire family and may create breakdowns in communication and trust. It is our belief that in order for a young person or adult to be successful in overcoming their alcohol or drug problem, the family needs to understand addiction, learn the importance of the family support in recovery and make adjustments in their own behavior. Family members also need support during the treatment process.

The family program is specifically designed to help families explore relevant subjects such as:

  • Understanding the addiction process
  • How addiction affects the whole family
  • How to recognize and prepare for possible relapse
  • Roles within the family and how to develop better communication

Families also benefit from having the opportunity to meet and exchange ideas with other families in similar situations. Individual family counseling sessions may also take place during treatment.

No treatment facility or social institution can replace a family's supervision and care. From the moment an individual enters treatment, we must help him or her begin the process of transition to a long term environment supportive of lasting recovery. Individuals in treatment who have family supporting their recovery stand the best chance of having a life of freedom and choice.

Within the family system, a problem experienced by one member affects all members. Family members may benefit from help and support with their issues and may be struggling with active substance abuse, emotional problems and the consequences of abuse and trauma in their lives. Family members are encouraged to engage in the recovery process and to participate in counseling and education sessions aimed at ensuring that their loved one in treatment will benefit from an ongoing support system after completing our program. 

Family members or friends can find additional support during their loved one’s treatment and recovery by attending community support groups such as Al-Anon or Alateen.
