Founder of Diamond Grin

Meet Stéfany Riboura.

Hi, I’m Stéfany. Originally from Brazil, I moved to the U.S. in 2020 and founded Diamond Grin a year later. Today, I call San Mateo home and bring a personal whitening experience to clients throughout the Bay Area.

My background includes dental studies in Brazil, experience as a dental assistant, and training in cosmetic teeth whitening. Since 2021, I’ve served more than 1,000 clients, bringing the same attention to detail and welcoming approach to each appointment.

Inviting someone into your home takes trust, and I don’t take that lightly. I take time to answer your questions, explain what to expect, and check in on your comfort along the way. From our first conversation to your aftercare, I want you to feel informed, comfortable, and personally cared for.
