Drug Rehab


Serving New Hampshire and Tennessee Areas

Although we receive clients from all over the country, GateHouse Treatment’s flagship location in Nashua, New Hampshire, is perfectly positioned to serve the New England area. And with our upcoming location in Nashville, we will be able to serve the Southeast, where opioid deaths continue to rise above the national average.

Why New Hampshire and Tennessee?

While our choices for locations tend to weigh heavily on an area’s need, New Hampshire certainly has attractive qualities and is full of New England charm. With Nashua’s Main Street just a few miles away, shopping, recreational activities, and great restaurants can all be part of sober fun activities on weekends. Meanwhile, the beautiful countryside in New Hampshire allows clients to take a break from otherwise chaotic lives while in active addiction.

Our soon-to-be-open Tennesse location will be near Nashville, one of the South’s fastest-growing cities. Nashville is also a major center for healthcare and educational institutions.

New Hampshire

Founded in 2009, GateHouse Treatment is one of the leading drug rehabs in New Hampshire, serving the greater New England area. The treatment center is located conveniently minutes from downtown Nashua, NH, and less than 45 minutes from Boston, MA.

New Hampshire’s drug epidemic has reached an all-time high over the past few years. According to the NY Times, “the state leads the nation in overdose deaths per capita from Fentanyl, a powerful synthetic opioid that has virtually replaced heroin across New England.” The state is actively battling the growing crisis, and the role GateHouse Treatment plays in the New England rehab community is crucial.



Typically known for its beautiful mountain ranges and rivers, Tennessee and its neighboring states are challenged with opioid-related death rates well above the national average. Establishing a treatment center there in the coming months, our goal is to join the ongoing fight against the opioid crisis in the state and the Southeast.
