In 1987, Dr. Barack completed advanced implant surgical training at the University of Texas–San Antonio and has since integrated implant surgery into his periodontal practice. For more than 30 years, his work has focused on implant surgery and reconstructive procedures, with the past decade dedicated to refining techniques for esthetic implant outcomes and immediate provisionalization in edentulous arches.

Beyond his clinical practice, Dr. Barack has been committed to education, research, and service. He has authored peer-reviewed clinical papers, lectured nationally and internationally on implant surgery and regenerative techniques, and volunteered his expertise both locally in the Chicagoland area and abroad, including dental mission work in Honduras.
