McLean Hospital is a non-profit psychiatric hospital in Belmont, Massachusetts. Founded in 1811, it was the first hospital in New England and only the fourth special institution for the treatment of mental illness in America. McLean Hospital is an affiliate of Harvard Medical School and is noted for its neuroscientific and psychiatric research program, the largest of any private hospital in the world. It is also noted for the excellence of its clinical programs and staff.

Family Member Quotes

“The OCDI not only provided our daughter the highest level of medical care as she worked to break the bonds of OCD, but it also provided us, as parents, with the support we needed to better understand our appropriate role in helping to foster her recovery. Personally and professionally, the OCDI served at the time, and continues in a variety of ways to serve, as a model vehicle for compassionate care and healing.”

“”With a debilitating disorder such as severe OCD, there’s a lot of confusion and stress for family, but even more so for the person suffering. McLean really was a life-saver in that their program took what was a dire situation, and helped all involved with understanding and coping with severe OCD. After McLean, my brother could return to a high-level of function in daily life, the improvement was as noticeable as it was necessary.”

Patient Quotes

“McLean’s OCDI was the only treatment program that enabled me to find relief from severe OCD. I had tried other reputable therapists at notable facilities before coming to McLean’s OCDI and found their staff of professionals and treatment program to be far superior to any other program out there that I had tried before. My therapist and team there really cared about me and cared about my getting better. The individual care, personal connection, and support the staff at McLean afforded made all the difference for me. I came to McLean’s OCDI despondent from worsening OCD symptoms and desperate for help. I left there functional, happy, and more hopeful than I had been in a very long time. It was undoubtedly the hardest work I have ever done and the best personal investment I have ever made. The people at McLean’s OCDI have my eternal gratitude and it makes me very glad to know there is a resource and place like it out there for those of us who may need it.”

“I sought treatment at the OCDI at McLean and had extremely positive experiences. When first admitted I was suffering from severe OCD and had to take a medical leave of absence from college to attend. After my 6 week stay I was able to return to school and graduate. My therapist, social worker, and the counselors were essential in my recovery. I still talk to them regularly to share updates on my much more balanced and healthy life. Never in my wildest dreams would I have expected to find myself in a residential mental health program but it was just what I needed at the time and very successful for me.”
