Symptoms of schizophrenia are most likely to emerge between ages 19 and 24.

A new behavioral health hub for young people just diagnosed with psychosis is now open in Mesa.

Valleywise Health built the same kind of center years ago in Avondale. And officials estimate that a dozen more of the facilities are needed throughout metro Phoenix.

Valleywise’s new Mesa hub has room for about 90 short-term patients.
