When Dr. Harris came to Warrenton, finding one hygienist was quite difficult, and finding one good hygienist was even harder. Now Dr. Jeffrey Harris, D.D.S. benefits from the work of 4 fantastic hygienists. They are all incredibly skilled technicians, and have a friendly and sensitive rapport with each patient they see. Together, they have over 55 years of experience in Dr. Harris's practice alone.
