Behavioral Support & Services

Positive Behavioral Support to Learn New Skills, Improve Relationships, & Promote Independence.

Behavioral Services for Adults with Intellectual & Developmental Disabilities

Behavioral health is an essential element in holistic wellness. It helps us to regulate our emotions, cope with difficult situations, and improve our ability to function in everyday life. By understanding that a lifetime of experiences helps to shape our extraordinary individuality, we take a sensitive approach in looking at each person as a whole.

Through individualized, positive behavior supports, we celebrate strengths and self-determination within a trusting and inclusive environment. It is our belief that through connection and empowerment, we can help nurture relationships, achieve goals, support dreams, and encourage self-advocacy in all aspects of life.

To ensure continuity of care, we work collaboratively with caregivers and other trained professionals, across settings. Through an ethical and effective manner, we use data collection, observation, and the implementation of behavior support plans to teach individualized goals that we can monitor and modify through intervention and skill acquisition procedures as outlined by the Administrative Rules of Montana.
