Eichen House is a mental health facility within the fictional world of MTV's Teen Wolf.
During World War II, Eichen House was used as a military hospital. In addition to military personnel, Eichen was used to treat prisoners from the nearby Oak Creek Internment Camp.
During an outbreak of bacterial pneumonia, a number of prisoners died because one of the doctors was stealing and selling the M&B Sulphapyridine needed to treat the disease. This led to a riot and the release of a Nogitsune. None of the Eichen House patients or staff survived the ensuing slaughter. (The Fox and the Wolf)
Mental Health Facility
As a mental health facility, Eichen House appears to treat a full range of illnesses. It gained the nickname "Echo House" among its patients due to the way sound and events seem to echo there. (Echo House)
One floor at Eichen House is used by Dr. Conrad Fenris as a prison ward for supernatural creatures.
Several different types of shapeshifters are incarcerated there. (A Promise to the Dead)
Dr. Gabriel Valack was once Chief Medical Officer at Eichen and performed trepanation surgeries on creatures in the special ward. His theory was that the surgery would enhance their abilities. It worked but also resulted in their deaths. After regaining control of the hospital, he used the same surgery to amplify Lydia Martin's abilities until one of her screams shattered his skull.

Brunski was the former chief orderly who secretly killed several patients as an act of mercy; including Lydia Martin's grandmother. His sadistic demeanor kept the inmates in line. He also helped fellow patient Meredith Walker carry out the Benefactor plan through blackmail until he was discovered by Lydia and Stiles and, later, killed by Deputy Parrish.
Dr. Fenris works in the supernatural lock up portion of the institution. He specializes in supernatural creatures; particularly werewolves. He is fully aware of the inmates abilities and makes sure every precaution is taken seriously, especially with Dr. Valack. When Valack took over the hospital, he was "taken away" according to a patient.
Schrader is an orderly at Eichen House who becomes in league with Valack after the doctor escapes. He assisted Nurse Cross in "caring" for Lydia and he took enjoyment in poking her arm with a hypodermic needle multiple times until Lydia's powerful scream threw him against a wall. It is unknown what happened to him after Theo's pack break into Eichen House.
Nurse Cross is a stern and cruel nurse also working with Valack. She claimed that Lydia was faking her vegetative state and Cross did not hold back her cruel remarks towards Lydia. When Theo's pack broke into Eichen House, she and Valack enter an old lab below the hospital. When Valack placed a Dread Doctor helmet on her, it killed her and her body is now stashed in a Plexiglas cell.
