TRI-COUNTY DENTAL HYGIENISTS' ASSOCIATION

Get to Know Us

We are a component of the Ohio Dental Hygienists' Association as well as a part of the American Dental Hygienists' Association. Our component is in Northeastern Ohio and consists of three counties: Trumbull, Mahoning, and Columbiana. 

Tri-County DHA is committed to being an organization that supports our local hygienists' so that they may continue to learn and grow in their careers as dental hygienists. Please feel free to look around our site and contact us with any questions.

​

Our Ohio Dental Board approved Medical Emergency course can be found on our Events Page. Upon completion of this course and other manditory requirements the dental hygienists may practice without a dentist present.
