CMSU Behavioral Health and Developmental Services

The CMSU system provides a wide range of mental health, intellectual disability and drug & alcohol services to the citizens of Columbia, Montour, Snyder and Union Counties in the Commonwealth of Pennsylvania.

Each year, CMSU and its network of providers serves over 4,000 people. Our mission is to participate actively in a community-wide partnership to support the residents of Columbia, Montour, Snyder and Union Counties in achieving independence and personal development in order to enhance their quality of life.


Who is Eligible for Services?

In order to qualify for services within the CMSU system, you must live within the boundaries of Columbia, Montour, Snyder or Union Counties in the Commonwealth of Pennsylvania. If you do not live in one of these four counties, you are not eligible for County-funded services with CMSU. Call the County Courthouse for the county you live in to contact similar services in your home county of residence.


What is Mental Health?

Mental Health is a relative state of mind in which a person who is healthy is able to cope with and adjust to the current stresses of everyday living. If a person is unable to cope or adjust to everyday living, then he/she may have a mental illness. This is a term that refers collectively to all of the diagnosable mental disorders. Approximately 20 percent of the U.S. population have been diagnosed with a mental illness.


What is Intellectual Disability?

Intellectual Disability is a diagnosis given to an individual who is determined to have significantly sub-average general intellectual functioning that is accompanied by significant limitations in adaptive functioning in at least two of the following skill areas: communication, self-care, home living, social/interpersonal skills, community use, self-direction, functional academic skills, work, leisure, health and safety. The onset must occur before the individual's 22nd birthday.


What is Early Intervention?

Early Intervention is a collection of supports and services for infants and toddlers from birth to 3 years of age who have developmental delays. The focus of Early Intervention is to help families with children who have developmental delays to enhance their child's development. Some of the supports and services included in Early Intervention are physical and occupational therapy, speech therapy, vision therapy and hearing therapy, and developmental specialist services.


What is Drug & Alcohol?

The CMSU Drug & Alcohol Program provides services for the prevention, intervention, and treatment of the abuse of alcohol, tobacco, and other drugs. These services include assessment, referral and case management. Financial assistance is available for those who qualify.
