In 1988 Dr. Stewart decided to pursue education in the newly emerging field of cosmetic dentistry. By 1990 Dr. Stewart was awarded accredited status in the American Academy of Cosmetic Dentistry after his successful slide presentation of specific cosmetic cases and written reports before a panel of cosmetic dentistry experts. He was the first dentist in the state of Michigan to achieve this level of recognized expertise. The following year he was asked to serve on the five-member Accreditation Review Board. He has since served two terms as the Accreditation Chairperson, one term on the Board of Directors of the AACD, and he is currently the Fellowship Chairperson of the same organization. On behalf of the AACD, Dr. Stewart has taught advanced accreditation techniques to groups of aspiring accredited dentists. These seminars have taken place in Chicago, St. Louis and Minneapolis.
Dr. Stewart is a member of the American Dental Association, Michigan Dental Association, the West Michigan District Dental Society, the Academy of General Dentistry, the Francis Vedder Society of Crown & Bridge Prosthodontics, the Seattle Study Club, the Grand Valley Dental Forum and the American Academy of Cosmetic Dentistry.
Dr. Stewart has taken more than 1,000 hours of continuing education, including courses at the Center for Esthetic Excellence in Chicago, the Dawson Center for Advance Dental Study in St. Petersburg, FL, the Center for Restorative Excellence in Tacoma, WA, Louisiana State University, and Bethesda Naval Hospital
