Introducing The Steward House at Silver Hill

Discover our confidential, intensive mental health treatment program for executives and professionals in collaboration with Yale New Haven Health and Yale Medicine.

  • The Steward House is the newest transitional living program at Silver Hill Hospital in New Canaan Connecticut. We are a program that specializes in the treatment of Executives and Professionals who have mental health and addiction problems.

    I believe that the collaboration between Yale New Haven hospital and Silver Hill Hospital creates a unique opportunity. Each of these institutions is world class in their own right. And coming together creates unique opportunities for synergies.

    We really emphasize the clinical care, that’s number one for us. And we emphasize collaboration. So the patient really being at the center of the treatment team.

    These are individuals who have extraordinary levels of responsibility. Things can quickly turn from being a problem of self management, into a very serious problem with self care that requires professional treatment.

    Each treatment team consists of a psychiatrist, psychologist, as well as a primary clinician. And all of our group programming is run by social workers here at the hospital. The program is both very structured so our patients will have approximately five to six individual treatment hours a week and at a minimum fifteen group therapy hours. In addition to that our patients will engage in a number of wellness oriented activities so that might be physical therapy, nutrition counseling, yoga, meditation, and so it’s very structured but also very tailored to the individual.

    That’s the main focus on the treatment is giving them, when they leave the copping skills that they need in these areas of self care that they haven’t paid enough attention to when they were, before they came here.

    I think of it as a program that is meeting the needs of this population. So this is more like an intensive care unit. And if we think about it that way, making the investment to come to Steward House can be the most important investment that these people can make in their lives.
