Arman Sadeghpour, PhD

President and Chief Executive Officer

Arman Sadeghpour's graduate research at Tulane University confirmed that Rennou™ works better than fluoride to strengthen teeth.

Sadeghpour has lived in Louisiana since 1975 and the avid New Orleanian did not let Hurricane Katrina stand in the way of his PhD. His thesis advisor left the Big Easy after the storm. It was fate that Dr. Tetsuo Nakamoto agreed to oversee his thesis and Sadeghpour changed his topic to collaborate with Nakamoto.on the effect of chocolate extract on human teeth.

Sadeghpour found time during that post-Katrina period to become actively involved in the university's student government. The storm forced the historic closure of the university for an entire semester and Sadeghpour played an integral role communicating and coordinating with returning students as their elected student body president.

He is a founding member of Theodent, LLC and is committed to helping New Orleans strengthen its economy and rebuild, post Katrina.
