About Us

The Summerill Group, LLC consults with local governments on Intergovernmental Service Agreements for housing Federal prisoners and detainees in county and city jails.  We use our proprietary cloud-based algorithms, called i-detain, to calculate your per diem rate and hospital guard / transportation rate.  Next, our specialists prepare and submit your proposal to the U.S. Marshals Service or Immigration & Customs Enforcement, so that we can then partner with your office during the government’s review of your proposal as well as any negotiations with the Federal Government.  With over 20 years’ worth of experience, our turn-key solution has assisted over a hundred local governments in thirty different states.
