Faculty And Staff

All of us at Arizona School of Dental Assisting are honored to prepare students to attain their dreams and enrich their communities.

Lisa Stevenson

President, Owner


Mrs. Stevenson is a native of Arizona. She attended high school in Arizona and went on to attend SCC and NAU and she is a graduate of a Dental Assisting program. She is X-ray certified by the Arizona State Dental Board of Examiners. Mrs. Stevenson has been in the dental field for decades and has been involved in many different specialties in the field. However, her expertise encompasses supervision and clinical instruction for future dental assistants.

She has also played a big part in the training for the other dental assistants on staff and had decided with Dr. Divito to open a dental assisting school that would prepare students with the knowledge and technical proficiency that will allow them to become immediately employable in a dental office upon graduation.

That mission started when Dr. Divito and Mrs. Stevenson opened the school in 2001. It has continued to train well-needed assistants for this field.

Mrs. Stevenson is very much involved with the everyday happenings within the school and with each and every student that comes through the school, thus making the school a great success. With that being said, our success is the success of our students.

Enrico DiVito, D.D.S.



Lisa and I started a dental assisting program in 2001 to alleviate the dentist from spending chair time training and also saving a potential student from spending to much time and too much money learning to be a dental assistant. Here we are approximately two decades later and our success shows through our students and the longevity of the program!
