About Us
InSite Health is redefining outpatient psychiatry for children and adults. InSite provides local communities access to in-network, high quality psychiatric care. We meet patients where they are: at home, at school, or at one of our convenient locations.
We offer mental health care to families, schools, nonprofits, colleges and organizations throughout New Jersey. InSite also offers preventative mental health training and programming for school districts.
