Dr. Hayes has practiced dentistry for 18 years previously in Milwaukee, Wisconsin, Dallas, Red Oak, and Waxahachie, Texas. The HGCD School of Dental Assisting, LLC was developed as an effort of Dr. Scott Hayes. He recognized the need for well-trained, efficient chair-side dental assistants and found difficulty in attracting good assistants throughout his years in practice.
