Throughout this presentation I'm going to *mention some words about doctors.
Introducing, I would like to point out that Doctors—also referred to as physicians and medical practitioners—are healthcare professionals who promote, maintain, and restore health through studying, diagnosing, and treating illnesses, injuries, and other physical ailments.

*If you're doing a presentation is better to use the word "mention".
If it is a written paper, "state" is a better option.
"Utter" is correct, but old-fashioned.
