A Per Diem Speech Language Pathologist is a licensed professional who provides speech, language, and swallowing therapy services on an as-needed or flexible basis, rather than as a full-time or permanent employee. These therapists are often called in to cover staff shortages, increased patient loads, or to offer specialized services in hospitals, schools, or rehabilitation centers. Per diem positions offer flexibility in scheduling and can be ideal for clinicians seeking work-life balance or supplemental income. The role requires the same credentials and clinical skills as full-time positions, including assessment, diagnosis, and treatment of communication disorders.
