Meet Dr. Guillen

Some of his patients call Dr. Omar Guillen the best dentist in LA. His dedication to personalized care encompasses all of your needs (physical, emotional, and financial). In fact, he’s shaped his current practice (Westwood Village Smiles, a cozy dental office near UCLA) to combine the most technologically advanced treatment options with a comfortable, inviting environment. This allows him to provide an exceptional level of care while minimizing the discomfort most people feel upon visiting the dentist. Even kids love coming to see Dr. Guillen and fun staff at Westwood Village Smiles.

Professional Education and Accreditation

Dr. Guillen is a lifelong California native, born and raised near Whittier. From a young age his passion for perfection has pushed him to set his own personal bar very high—a trait that has only benefitted the thousands of patients he’s treated over the years.

He began his studies in the biochemistry program at UCSD. Upon completion he expanded his education at California’s premiere Dental School: University of the Pacific in San Francisco (which has been ranked among the best for three decades running). Not content to limit his practice to general dentistry, Dr. Guillen undertook post-graduate-level training in Oral Surgery at Yale University. He topped his collegiate-level training by completing aesthetic and cosmetic dentistry curriculums at both UCLA and USC.

Passion for Personal Improvement

But Dr. Guillen’s education didn’t stop at graduation. He actively stays up-to-date with the most advanced treatment options available including 3-D imaging, laser dentistry, and the use of the revolutionary Invisalign® system to provide patients with the best possible smiles with the least discomfort.

This well-rounded approach to general dentistry has allowed Dr. Guillen to provide a complete variety of oral care options from minimally invasive repair procedures like fillings to complex oral surgeries and cutting-edge restorative and cosmetic procedures. In fact, when patients visit Dr. Guillen’s dentist office near UCLA they are rarely referred to other specialists because almost every procedure can be performed in-house—saving time and money.


Spreading His Passion to the World

Not only is Dr. Guillen a respected family dentist in Westwood, he’s also a sought-after lecturer and educator. He continues to improve the level of service offered by other dentists around the globe through regular speaking engagements and personal trainings at symposiums from Australia to Argentina.

Through these talks he passes on the best practices of dental implants and aesthetic dentistry to the next generation of family dentists worldwide. That commitment to the global community drives him to devote much of his personal time to humanitarian efforts in less-fortunate regions of the world like Western Australia, Central America, South America, and Asia.

When he does have a bit of free time for himself, Dr. Guillen prefers to spend it outside—enjoying the bounties of living in California by hiking, skiing, and running.
