Speech, Language & Learning Center, Inc. was originally established in 1992 as Jefferson Speech and Language Center of St. Tammany.   Since its inception, the business was exclusively located in the Mandeville area.  We launched our Slidell Branch in 2017 to assist the growing needs of children in the eastern part of St. Tammany Parish. SLLC employs Masters leveled Speech-Language Pathologists who hold Louisiana Licenses and are nationally certified from the American Speech, Language, and Hearing Association.  We are philosophically committed to the patient’s total communication and learning needs through family involvement, coordination of school and professionals, counseling and referral for associated services where indicated.

In treating the child, we emphasize earliest possible intervention, as the most critical age for speech and language development extends from birth to three years.  The more sophisticated skills of reading, writing and math build on this already established system.  Reading comprehension is a secondary language skill that has phonetic, grammar, semantic and memory components.  If secondary learning (Reading, Writing, and Math) do not proceed satisfactorily, then the language system should be examined.  Research and clinical experience overwhelmingly demonstrate that intervention and remediation at a young age contribute to a child reaching his/her full potential.
