About Hamilton Center Greencastle
Hamilton Center Greencastle is an outpatient addiction treatment center in Greencastle, Indiana where they serve adults, adolescents and families across Putnam County.
Their services span outpatient addiction treatment and assessments along with individual and group counseling and treatment for co occurring conditions.
The Matrix Model of Recovery
Hamilton Center Greencastle uses a structured Matrix Model IOP that runs for a minimum of 16 weeks, with sessions three times a week. The curriculum combines relapse prevention training and education with social support groups and family education.
You'll also have 12 step meetings and relapse analysis. They take consistent attendance seriously and your treatment will mostly be in groups of 12 to 15 clients.
This is a fixed and curriculum-driven commitment rather than open ended outpatient therapy. You could think of it like you're taking a class in recovery.
There's on site screening in the program too, and clients pay $25 for drug screenings. For someone in Putnam County who needs an outpatient path with a clear timeline and accountability, this structure can be a helpful fit.
Linked Primary Care Through Grace Clinic
I think it's unique that Hamilton Center Greencastle shares its Hillsdale Avenue address with an affiliated Grace Clinic primary care office. This co-location integrates medical care with behavioral health and addiction services at one site so they can help with your overall health as a team.
The center also links to a Military Veteran Program addressing addiction alongside PTSD, reintegration and family stressors, making it relevant for veterans in the area.
This clinic serves central and west central Indiana and they accept Medicaid, Medicare, TRICARE, private insurance and self pay. They have a sliding fee scale and a policy that they won't turn away anyone for an inability to pay.
