Leslie Houston
Program Director and Professor, Dental Assisting
Email: lhouston@cocc.edu
Leslie approaches her chosen career with compassion and empathy. "I became interested in the field when a dental assistant helped me overcome my dental anxiety," she explains. "I experienced firsthand the difference a dental assistant can make."
As a nontraditional student and mother of three children, Leslie decided to take the leap and apply to COCC's Dental Assisting program. "It was a career where I could help others and contribute financially to my young family."
After graduation, Leslie worked as a dental assistant but was soon asked to return to COCC as a lab assistant. She continued her education and completed her Associate of Arts Oregon Transfer degree at COCC and earned a Bachelor of Applied Science in professional technical education and instructional design at South Seattle College.
Teaching a full array of Dental Assisting classes, Leslie enjoys helping students reach their goals and realize their potential. "The absolute highlight is watching a student secure employment in a dental practice where they are an essential member of the dental team," she shares. "We know we've succeeded when students tell us that they love their career."
