“What an amazing experience. Raussie did an amazing job doing my deep cleaning and I can’t thank her enough for a beautiful cleaning and Dr. K was so straight forward and helpful. Nancy? She’s an ANGEL. Helped me so much getting in before the end of the year for insurance purposes. Please, do not hesitate. You should be at Smile LA!”

“Smile LA has an excellent staff that conducts thorough examinations to ensure they can get to the root of your issues. Dr Yousefzadeh was very knowledgeable and kind. I felt comfortable discussing my issue with him, and he explained the problem properly, using visual tools to help me fully understand why it was happening. I believe his suggested treatment is reasonable and will definitely be going back again.

I was long overdue for a visit and had been putting it off due to fear and embarrassment, but the staff's kindness and respect made me feel at ease from the start. My dentist was particularly gentle and attentive, making sure I was comfortable throughout the entire process. I'm grateful for their care and look forward to my next appointment.??????????????

Office staff was so nice. Dr. K took his time to review our plan of care. He is really personable & has a fabulous staff. Looking forward to being a client of his.
September 6, 2025Justin R.Verified patient
This place is fancy and high tech but tried to seriously upcharge me, and told me that my insurance wouldn’t cover my treatment when another dentist also in my network took care of me free of out of pocket charge. Don’t let them pressure you into a big payment plan that you don’t need.

It had been years since my last dental visit, and I came in worried about discoloration, cavities, enamel concerns, and gum recession. Dr. Kourosh and his team provided a very thorough assessment and created a clear plan to maintain and improve my dental health. They took the time to explain everything in detail, which really helped ease my concerns and gave me confidence moving forward. I left feeling reassured and motivated to stay on top of my dental care.

Loved the experience here. Dr. K was so friendly as it was my first time here and gave me very informative details about my teeth health. Shoutout to Nancy for being very patient with me while I asked a million questions about insurance. Will be back for future services.

The staff was super understanding when I informed them last minute I was going to be late! Everyone was incredibly professional and super sweet. The Dr went straight to the point. I didn’t feel judged in any manner being here and they understood my financial situation as well and provided an alternative payment plan so I can afford the dental care I need.

i had an emergency with my wisdom teeth and Smile LA made the examination and extraction process so seamless and pain free. I get extremely anxious when it comes to the dentist and Dr. Kim and Dr. Kourosh made me feel so comfortable and cared for. I would recommend this dentist office to anyone that wants quality and comfort.
