The New Generation of OC Speakers

Updated: May 31

Like New Kids on the Block, they got the right stuff.

Global Orthodontic Leaders

There is no argument; OC has the single best speakers line-up of any orthodontic company. The progressive talents of experienced speakers Dr. Pitts and Dr. Brown have been guiding the future of our industry for decades. They also lead an extremely talented group of global educators. These speakers include the Algerian super duo of Dr. Wassim Bouzid and Dr. Ilias Tibaoui, and a rockstar group of talented South American influencers.

To be a world-class bracket company, OC also needs to promote a new generation of speakers who represent our brand identity and product philosophy.
