About Us


Quality of life is something no one should have to forgo. At the Anne Sippi Clinic, we are dedicated to this philosophy. We use medication judiciously to decrease symptoms of psychosis, and maintain a stimulating environment that enables our clients to explore their potential within ASC and their greater community.



The Anne Sippi Clinic empowerment and recovery model:


  • Provide a better quality of life for our clients, reducing the need for hospitalization and restrictive or segregated living
  • Foster personal empowerment while reducing social isolation and stigma
  • Help all persons with mental illness to achieve their potential as co-workers, neighbors and friends; offer supported employment to all participants, regardless of illness status or functional ability
  • Involve families in treatment planning and interventions, facilitating reunification and healthy family dynamics
  • Teach psychological skills for problem solving, emotional regulation and adaptive responding to life’s stressors


Each client’s experience plays a central role in treatment and assessment at ASC. Improved quality of life is our greatest measurement of success.
