Student membership in the American Dental Hygienists' Association is the 2nd most important step (after getting accepted into dental hygiene school!) to becoming a consummate dental hygiene professional! Student membership in ADHA represents the student voice from across the country. Membership is open to all students enrolled in entry level as well as degree completion and graduate level dental hygiene programs. Plan to visit this page often and take advantage of the numerous opportunities extended to student members in ADHA and the California Dental Hygienists' Association.
