Josh Duggar is seeking treatment at Reformers Unanimous in Rockford, Illinois, a source confirms to ET.
The facility offers faith-based treatment and is the same place the Duggar family has lauded in the past.
"We love the Duggar family," Tony Richardson, Director of Development at Reformers Unanimous told ET on Friday, though he declined then to confirm Duggar was a patient. "Our hearts and prayers are with them."
Richardson says the center has an "over 80 percent success rate," adding, "success defined by being free from destructive habit. Richardson elaborated, "They no longer fall prey to that. Second definition is that they are employed. Third is getting involved, and attending a local church. Local church is God's support group and that is important to recovery."
Men at the facility were seen being taken via bus to church on Sunday, where they entered via a basement door. They will spend 40 hours a week doing community service work and stay in "military-style barracks," a source told ET.
No trespassing signs are abundant on the property.
In May 2015, Josh Duggar admitted to molesting five young girls as a minor, and in August, the 27-year-old confessed to being unfaithful to his wife Anna after being discovered in a data breach to have two paid accounts on the affair-oriented website, Ashley Madison. Josh checked himself into rehab last week, possibly seeking treatment for his sexual issues.
