General Dentist
Dr. Leon Ren
For over 20 years I have dedicated my practice to creating profound improvement in the quality of my client’s lives through Cosmetic Dentistry. To me, this means making a lifelong commitment to each of my clients’ happiness and wellbeing.

My conviction for fine cosmetic dentistry comes from a unique passion I share with few others in my field. I discovered my artistic talent at a very young age and have pursued the study of art ever since. Being able to combine my natural talent for painting and fine cosmetic dentistry allows me the privilege of truly enjoying my profession. For this reason, cosmetic dentistry fulfills an important component of my life’s purpose. Throughout my 20 year career in Cosmetic dentistry, I have created thousands of amazing smiles for celebrities, athletes and ordinary people who strive to improve their lives. Knowing that my artistic talent applied in cosmetic dentistry can change people’s lives is the most rewarding experience. From this inspiration, I have formed a charity foundation “Life is Beautiful Charitable foundation” to use my professional skills to help victims of abuse and hardship transform their lives through cosmetic dentistry. In addition to cosmetic dentistry, I have made a personal commitment to continuously strive for excellence in the areas of health, spirituality, and mind within my own life. I aim to help my client create the same level of excellence in theirs.
