Dr. PeyRey

Full arch and full mouth implant specialist, kois graduate, practice owner, lab owner, dental educator, mentor, speaker, industry influencer, key opinion leader

Dr. Peyman “PeyRay” Raissi is a dentist from the USA who specializes in oral implantology and full-arch/full-mouth reconstructions. He obtained his doctorate from the University of Tennessee College of Dentistry. In addition, he studied at the Middle Tennessee State University and completed the New York University Stony Brook Implant Residency Program.

Dr. Peyray has been a featured guest in several dental podcasts over the years and even hosted one with fellow Nashville dentist, Dr. Sully Sullivan (The Millennial Dentist) for a few years. The duo decided one day to get together, have a few beers and record a podcast, not knowing a direction or who would even listen. Almost 100 episodes later, the two have interviewed some of the biggest names in dentistry and amassed thousands of subscribers. Topics of the podcast range from owning a practice, to digital workflow and everywhere in between – the Millennial Dentist way.

Dr. Peyray and four of his friends came together with the idea of connecting all of their Instagram peers in one place – thus, the Dental Influencers Alliance (DIA) conference was born in 2018. The first annual conference was held in Los Angeles, California in December 2018 and was attended by more than 300 people who fell in love with the conference – raving that it had “broken the mold” of traditional dental conferences. The success paved the way for DIA 2.0 and 3.0 which each gathered 500+ dental professionals.
