Dr. Laila-Christine Assad


Dr. Laila-Christine Assaad joined Smile City Dental in 2015. She is a warm and compassionate dentist who was born and raised in Montreal, and recently moved to Los Angeles after practicing dentistry for the past 6 years in New York City. She completed her college education with honors and decided that being a dentist was how she wanted to contribute to the health community, receiving her dental degree from the University of Montreal in 2009. Following graduation, she chose to complete a general practice residency at Columbia University’s New York Presbyterian Hospital, one of the top 10 hospitals in the United States. This further expanded her capacity to perform complex procedures and treat medically compromised patients.

Dr. Assaad is devoted to her patients and believes that a beautiful smile is the best asset one can have. A healthy smile not only makes you feel and look better, but it is also essential to your overall health. It is important to Dr. Assaad that her patients are happy, comfortable, and understand the reasons for treatment and how to promote good oral hygiene

Dr. Robert Lim


Robert Lim, D.D.S. graduated from Harvard undergrad in 2002. After a brief stint in New York for investment banking, he went back to UC-San Francisco for dental school, graduating in 2011. He finds his new career path deeply rewarding, helping his patients attain the oral health and beautiful smiles they deserve.

A native of Massachusetts, he does miss his Boston sports teams and autumn colors. However, this is far outweighed by no winters in California, and the tastiest Korean, Japanese and Mexican food nearby. He is also a big fan of In-N-Out.

Dr. Lim is a member of the American Dental Association (ADA), California Dental Association (CDA), Los Angeles Dental Society (LADS).
