John Lybolt, PhD, CCC-SLP, BCS-CL

With a professional career in three widely variant geographical and cultural settings, I have practiced in a university, nationally recognized medical diagnostic center, and private practice. Currently, I work in a not-for-profit dedicated to Speech/Language support in communities of greatest need. I have a well-formed point of view regarding academic, social, and pragmatic language skills. As a clinician, student supervisor, and presenter, I task myself to understand the system or the "story" within a client’s output before attempting to make therapeutic or professional change. Standardized assessments and analyses of spoken output provide insight regarding a child’s current language/speech output. Our team focuses on the system, not the "error."

In a long and productive association with LEAP (Language Empowers All People) we found ourselves writing original program materials engaging the child language and social issues that we were asked to address. Our programs were written based on current child language research, and the client needs we were serving. Our research-based and data driven programs led to multi-year grants, broad community support, and awareness within both the Chicago area and nationwide.
