Who We Are

Founded by Experts

Our team has experience in clinical dentistry, molecular cell biology, genetics and immunology.

Tina Saw, DDS

As the CEO of Oral Genome, Dr. Saw has always been forward thinking. She believes in breaking the barriers to dentistry and eliminating the drill and pain of dentistry.

As a general dentist in Carlsbad, California and a Loma Linda University School of Dentistry graduate, Dr. Saw has always focused her dental practice on prevention and helping her patients achieve their best smile.

Dr. Saw knows getting dental procedures is not always everyone's favorite thing to do, and many people avoid going to the dentist because of past bad experiences.

She founded Oral Genome so people can understand what affects their dental health and how to target specific salivary factors to reduce their risks for dental problems.

Dr. Saw is recognized as an expert in the dental field and has been a guest speaker for many dental groups. She has also been seen on Fox News, Yahoo, Shape Magazine, and most recently CBS for providing someone a life changing smile transformation.

Thanh Luu, DDS

Microbiology and immunology has always sparked Dr. Luu's interest. As someone who is always interested in learning new things and creating a better mousetrap for things, Dr. Luu is committed to innovation and making dentistry easier for both patients and dental professionals.

Dr. Luu is a general dentist in Carlsbad, California. He believes that people can prevent oral diseases before they begin. His experience at a San Diego non-profit dental clinic has taught him that preventive care triumphs over restorative care.

Susan Zneimer, PhD, FACMGG

As a director of clinical genetic laboratories for over 20 years, Susan holds a doctorate degree in the field of genetics and is a board-certified cytogeneticist by the American Board of Medical Genetics. She is also a Fellow of the American College of Medical Genetics and has published two medical reference books on genetics by Wiley Publishers.
