Our therapists are licensed, experienced, and have additional training in specialty areas such as sensory integration (SIPT certified), PROMPTs for Restructuring Oral Muscular Phonetic Targets (PROMPT), Neuromuscular Electrical Stimulation (NMES or "Vital Stim"), and feeding dysfunction.  Continuing education classes are attended regularly to remain current with new theories and treatment techniques.
