“Most early Colorado dentists were individualistic, content to exist by the broadest interpretation of laisse-faire principles and suspicious of any effort to organize their activities. … However … the [Colorado State Dental Association] broke through the barriers of public and professional indifference to secure legal recognition of a code of dental ethics.”William Alan Douglas

Dr. William Smedley

At the first official meeting of the then-Colorado State Dental Association, held June 7-8, 1887, Dr. William Smedley was elected the first president of the association, along with Dr. John Grannis, first vice president; Dr. B.W.
