Get to Know Your Local Dentists

Dr. Kevin Badii

Managing Doctor and Orthodontist

Dear Patients and Friends of OC Smile,

Thank you for allowing me the opportunity to introduce myself to you! I am an Orange County native, and after graduating from El Dorado High School, I attended the University of Hawaii on a full football scholarship. Due to injury, I received my undergraduate degree, in Biology, from California State University at Stanislaus. While at CSUS, I served as the team captains for both the Men’s soccer and Men’s track teams. I received my Doctor of Dental Surgery (DDS) degree from USC School of Dentistry, where I graduated with honors and became a lifetime member of Omicron Kappa Upsilon, the esteemed National Dental Honor Society. I received my Specialty Orthodontic Certificate and Masters of Dental Science (MDS) Degrees from the University of Connecticut. I am a Diplomate of the American Board of Orthodontics, an extraordinary accomplishment achieved by a very small percentage of orthodontists.

My wife, Dr. Bonnie, and I have 3 beautiful children. We’re “OC Locals” and enjoy all the awesome amenities the area has to offer. In my free time, I enjoy spending time with my family, being active outdoors, and reading. I find importance in demonstrating solid values and morals, and I have always pursued excellence in my personal and professional life. I look forward to working with you to help create your beautiful, long-lasting, smile.

Yours in Health!

He graduated from Sunny Hills High School before receiving a B.S. degree in Biology from Stanford University. After receiving a DMD degree from Washington University in St Louis, he moved back west to Arizona, where he practiced general and cosmetic dentistry 32 years before selling his offices and returning home to Fullerton in 2018.

Dr. Hyneman is married to his wife Roberta, a dental hygienist, and has two grown children. His daughter, Rachel, has a PhD in particle physics, and is completing a post-doctorate degree at Stanford’s Linear Accelerator Center. His son, Daniel, has earned both DDS and MD degrees, and is in his fourth year of an oral and maxillofacial surgery residency at LSU Medical Center.

Dr. Hyneman and his wife enjoy home renovation in their spare time, as well as downhill skiing in Durango, Colorado, where they have a small second home. Additionally, he enjoys building experimental aircraft and has completed two projects.

Dr. Hyneman is passionate about what he does, striving to provide excellent care to all. He truly treats his patients like family!

Dr. Tra Tran

Hello, my name is Dr. Tra Tran, and I am an oral healthcare professional who believes exceptional patient care lives at the intersection of innovation and empathy. My journey began at UC Berkeley, where I earned a B.S. in Bioengineering. Beyond the technical rigor, Berkeley instilled in me a deep respect for integrity, intellectual curiosity, and a commitment to serving
the community through shared knowledge.

Driven to bring these values into direct patient care, I moved to the East Coast to earn my DDS degree from the NYU College of Dentistry. Today, I blend an engineering mindset with clinical expertise to deliver care that is both precise and compassionate. I am committed to continual learning, refining my craft, and ensuring every patient feels heard, understood, and cared for.

Outside the office at OC Smile Dental & Orthodontics, you’ll often find me on the court playing tennis or pickleball—always in search of a good game, a great story, or a fresh perspective.

Very pleasant experience today. My normal dentist is closed on Fridays. I had an emergency visit today for my son. Lindsey was very helpful and made the overall experience pleasant. So thankful OC smile is open on Fridays and Saturdays. I will be returning to OC smile. I highly recommend this dentist. I am now considering them for Orthodontics. CC
