Check out what some of our happy patients are saying about us:

Hojat P. from Los Angeles, CA (Source: Yelp)


Everybody is polite, genuinely nice and professional at Smila LA. After neglecting my teeth for many years, I was hesitant to go back to a dentist. I was expecting to hear that I would need to fix every tooth. My last dentist more than 6 years ago had told me that I had 5 or 6 cavities. Surprise, surprise! I only have 3 minor cavities now. I needed deep cleaning which was expected and that’s about it. Dr K explained and showed everything to me and I felt confident that all the procedures are absolutely necessary. If you are looking for a dentist that you can really trust look no further. Thanks Smile LA

They have the best service here. I came here to get my treatment for cleaning, filling and deep cleaning. They did the great job on my teeth and I always book my cleaning every 3 months with them. I highly recommend Dr.K since he knows what he is doing. He is so professional in his field and if any treatment is not necessary he doesn’t recommend just to charge the patients. They are so caring and professional and nice staff.  They did validate my parking and i am happy that i found this place. Highly recommend to those that are looking for best dental treatment.

I was hesitant about this place at first, but I think that was due to my insecurities around finding a new dentist. I’ve had very bad luck. This place is a great find in the heart of downtown. Dr. Yousefzadeh is charming, and thorough. He’ll ask you lots of questions and you are free to ask many in return. I’ve found his staff to be very helpful, courteous, kind, and knowledgable. It’s easy to get good service when you’re at the office as well as when you are calling in. They use texts to remind you of appointments as well as to confirm, which is convenient for me. I’ve been in for an exam, deep cleaning, follow up to the deep cleaning, and a regular cleaning. There are comfy chairs, they partially validate parking, and the entire office is very cozy.

Dr. K is a wizard of dentistry, and has a great sense of humor!  I will not say it is pain-free, but it was definitely pain-minimal.  Thank you Dr. K for the fillings (although I didn’t want them), they turned out great – not just in function, but feel.  Normally, I would say that I cant wait to visit again, but given the context, I will simply say that if I had to visit again, I will gladly visit your office!

I had a root canal whilst on vacation in LA and they have been incredibly accommodating with this short notice. The physician did a fantastic job of my teeth and the women were very welcoming and helpful. I would certainly recommend it

Bryson M. from Seattle, WA (Source: Yelp)


This is the best dentist I’ve ever been to. Everyone is super nice and professional. I’ve had a cleaning, filling, and root canal with them and they were all a breeze. I almost fell asleep during the filling. I never had any pain or felt stressed. The shape and color of cap for my root canal was a perfect match. They took great care in getting it just right. Susanna at the front desk is wonderful to talk to and she always goes above and beyond to answer my questions. Dr. Yousefzadeh is quick, professional, and caring. I couldn’t ask for more from a dentist

Amg G. from Central LA, CA (Source: Yelp)


By far all I have to say is that Smile LA is the best dental office in Downtown,  I have been to at least 3 other dental offices before this one, the quality of their service is nothing compared to the others! I am so happy with Dr.K and his staff, they are always welcoming, and take care of your oral hygiene, I would love to keep writing details about this dental office, but I would rather suggest to visit and see for yourself.

Ashlyn Kramer (Source: Google)


Consulted with Dr Kourosh about possible porcelain veneers on my top 10 teeth about 3 months ago and it was a pleasant experience. He wasn’t pushy and was honest about me not needing my bottom done. His honesty sold me. He was more concerned with my needs than making more money. I had gone to 3 other offices and all of them told me I needed a minimum of 6 on my bottom. Yesterday I went into the office and tried on the temporaries. They look so gorgeous. I am very excited for this next chapter of my life. Highly recommend Dr K 10/10

Beverly G. from Los Angeles, CA (Source: Yelp)


I have been going to Smile LA for 2 years now and I can’t say enough great things about Dr. K and his staff.  Dr. K is very thorough in his exams and will explain in detail what problems he detects and the steps to move forward to fix the issues. He is also very accommodating with scheduling appointments. If you are experiencing pain, he works you in right away to make sure you’re taken care of. I had a temporary crown put in prior to getting a root canal, and after biting down on something hard, the temporary crown cracked. Dr. K was able to see me immediately to make sure this problem was resolved. After the root canal, I was able to get my permanent crown put in. I have had compliments by two separate hygienists about how great my crown is in terms of fitting and color. It makes me feel great knowing that I am in good hands when I go to see DR. K.

Beatriz C. from Los Angeles, CA (Source: Yelp)


Dr. Yousefzadeh is very patient and very thorough with his job. I am very satisfied with the customer service provided. A very friendly and professional staff. Officer manager Johanna is a kind and great person to deal with. Norma, the doctor’s assistant is the biggest sweetheart. I definitely recommend this dentistry if you haven’t come in for a check up I suggest you do. You will make them your favorite dentist! Granted that parking is a little complex but they do validate so don’t worry. And it’s walking distance from so many locations for tea, food, and desserts to enjoy after you did your part and visited the dentist. We all know not many like the dentist… They’re pretty cool!

Kevin W. from Central LA, CA (Source: Yelp)


This is the best dental experience that I have ever had and I am very picky. The whole staff is friendly, warm and inviting. They have state of the art equipment and they use the latest in dentistry techniques and technology. Lastly the facility is extremely clean. I highly recommend them!

This office saved me yesterday. Had a HORRIBLE tooth pain yesterday afternoon and found this place right before they closed. I called at 4pm and they said closed at 5pm and I was 30 minutes away. They said not to worry and that they would stay open for me. I was rushed in and Dr K met with me and said I needed a root canal immediately. I felt nothing when they gave me the shot and hardly anything the entire procedure. I was shocked. His bedside manner and energy was so great and he was so sweet and concerned. He reassured me everything would be ok. The entire staff stayed until I was finished and everyone gave me a big hug when I left the office. It’s nice to know there are people this genuine and nice left in this world. Thank you Dr K from the bottom of my heart.

Simfany B. from Los Angeles, CA (Source: Yelp)


I came into Dr. K office to receive Zoom whitening! My very first time whitening my teeth wasn’t sure what to expect but Dr. K and his team was nothing short of amazing made me feel Comfortable and at home and not to mention super please with my results. They go above and beyond reached out to me the very next day to check on me and remind me of at home care. I recommend this office to all my family and friends very convenient location!

Nicholas Morshed (Source: Google)


My family dentist had provided top quality dentistry my whole life. Now that I work past downtown I found the most amazing quality dentist in my backyard. My smile has never looked better and people continue to ask me how I maintain such great teeth. I highly recommend Dr. Kourosh to any new patients.

Harry B. from Los Angeles, CA (Source: Yelp)


Been my dentist for years and I wouldn’t dare trust any other soul with my pearly whites. I’ve become close with everyone in the office and love them so incredibly much- we have even all gone out for drinks and dinner after my late afternoon appointments! Stop looking and come see the best- Dr kourosh!

William W. from Los Angeles, CA (Source: Yelp)


Office is the best. Staff is friendly, helpful and competent. I never feel rushed and they ensure all my questions are answered prior to me leaving. My bill is always thoroughly explained. Dr Kourosh is friendly and attentive. He loves what he does and that reflects on his work. I definitely recommend this office.

By far best dentist I had!!! Let’s just say I drove an hour and a half to see him. If you have ever been afraid or nervous of shots. His shots do not hurt. Super friendly , knowledgeable dentist. His staff is amazing they make you feel comfortable and at home. I will not go to anyone else.

Haley Hudson (Source: Google)


Awesome doctor. Professional, clean, compassionate, doesn’t force you into unnecessary services, knowledgeable, gentle and just a good person. Office is organized, on time, and everyone is friendly.  There’s parking underground which is hard to find in the area and they validate it which is a plus. His cosmetic work is the best in LA, trust me I’ve searched everywhere 😉 Bravo everyone. Keep up the great work.

Mor S. from Woodland Hills, CA (Source: Yelp)


Dr. K is the best. This the first and only dental office I am glad to go to and not dreading it. Everyone is so nice and caring. Dr. K is honest and did a great job with my fillings. I didn’t feel a thing. If you are looking for a great dentist and dental office this is the place! Couldn’t be happier. Thanks Smile LA

Jackie P. from Central LA, CA (Source: Yelp)


Excellent Service! I couldnt be any more satisfied.  They helped me so much with my treatment. Dr. K and his staff are very attentive and always care for your well being! Feeling comfort and cared for is something very important to me. Thank you so much Dr.Kourosh and Smile LA staff!! LOVE -J.P.

Dr. Kourosh was great! I had to reschedule when I was already at the practice and he was very helpful and found a time that worked for me the same day. He did a great job fixing my broken tooth and explaining the procedure step by step. I will be back for a full check up soon!

I needed a root canal while on holiday in LA and they were extremely accommodating with such short notice. The doctor did a great job of my tooth and all the ladies were extremely welcoming and helpful. Would definitely recommend.

Benny A. from Los Angeles, CA (Source: Yelp)


Dr Koroush is a very thorough and attentive dentist. The staff was very welcoming and friendly. The office is very MODERN in design, organized, and  is very clean! Hygienist there was courteous and made me feel comfortable when sitting in my chair by relating with me, and patiently explaining the procedure I would be undergoing in detail. I got a positive vibe from the whole staff and doctor, did not wait long, and treated very respectfully. After such a pleasant experience I would definitely come back to Smile LA for future dental visits! Lastly I appreciate their transparency in regulates to cost. Great experience, professional practice, 5 STAR DENTAL PRACTICE!!

Linda A. from Los Angeles, CA (Source: Yelp)


I was pleasantly surprised. The staff is extremly efficient and Dr. K. is caring and knowledgable. I needed crowns for my front teeth and was really concerned about how natural they would look. I am extremely happy with my new crowns, as they are 100% match to my other teeth. The work was done in a timely manner and as promised, and I experienced no discomfort. Dr. K. and his staff take their time to do a good job and care about each patient.He will be my dentist for life and I highly recommend his office for all dental work.

Grateful I found this office. I was referred to Smile LA from my niece because I wanted to get porcelain veneers from someone exceptionally credible with good work. I saw a video of him placing porcelain veneers on a patient and I was hooked. I drove 2 hours away and came into his office for a consult. Dr Kourosh was very cool and down to earth which was refreshing. He quoted me a price that was right within my budget and I scheduled my appointment in the office. 3 months later my teeth are so natural and exactly what I wanted. Love this office and thankful for Dr Kourosh.

Ross E. from Los Angeles, CA (Source: Yelp)


The doctors here are amazing! I had my 4 wisdom teeth removed in one day. It took under two hours and I had minimal pain during and after the procedure. I returned to work the very next day and hardly needed pain medication. They were very patient and made sure to explain to me what to expect and made sure that I was not in pain every step of the way. The office is very clean and modern. The staff at this office are always eager to help, kind, and remember you after just one visit.

I have a dentist in westchester, but my sister told me to come to Dr Kourosh so I made an appointment for a teeth cleaning. The parking is in the building, I suggest leaving early to give yourself more time to find the room, I was late because it took me more time. I’m glad they had parking bc I you know how the parking is in downtown, bad. Going to Dr Kouroush’s office, I felt very welcomed by the employees. Dr Kourosh has a great personality. You can tell he loves what he does. I felt really clean after my teeth cleaning. I am thankful to have had a great experience, I highly recommend him!

Found this office on yelp and was impressed by the reviews. I stopped by for a cleaning after my Thanksgiving haha! I did a deep cleaning and I feel incredible. Best cleaning I’ve ever had no joke. They were able to squeeze me in last minute and was grateful for it. The staff was very polite and answered all my questions so now I am getting bleaching done here in 2 weeks for Christmas and NYE lol I’m pretty excited! I highly recommend this establishment 🙂

Jody S. from Central LA, CA (Source: Yelp)


You hear people talk a lot about how tough it is to find a mechanic you can trust, but I’ve found that the same is true for dentists. Unfortunately, I’ve had to have a lot of work done on my teeth, and I’ve seen several dentists over my time.  I feel like every time I go see a new dentist, I learn about all the things the last dentist did to mess up my mouth. After meeting Dr. K, I finally feel like I found someone I can trust. I went in originally for a consolation for teeth whitening, but Dr. K, informed me there were other issues I could (but didn’t have too) take care of first. I noticed a few weeks prior to my first visit that my gums had turned very pale. Dr. K explained to me that my gums had become infected. At no point did I feel pressured to use his services.His staff took very clear pictures of everything, and I decided to get a deep clean first. The process was super easy, and once it came time for the whitening, Dr. K once again explained everything to me and I really felt as if I could trust his judgement. Over all, I’m very, very pleased with the results, and I would highly recommend Dr. K and his staff to anybody that needs complete dental care. P.S. They have a super dope massage chair in the waiting room. My husband came with me to every visit but I know he really just wanted to use the chair.

Big ups to Dr.K and the wonderful dental technicians at Smile LA! I was warmly greeted, they did a thorough cleaning and inspection of my teeth and worked efficiently so I was able to make my meeting on time afterwards. Thank you again!

Kelsey B. from West Linn, OR (Source: Yelp)


I went to Dr. Yousefzadeh yesterday to get one of multiple fillings needed done. I’ve never had a filling before and it was so easy! I didn’t feel any pain because of the way he numbed my gum and was so grateful for his explanation of everything he was doing. He even used a mirror to show me what the inside of my tooth looked like and where the cavity was. I’ve heard so many nightmares about fillings and dentists in general, but this experience was a breeze. No pain or sensitivity today at all. I was really dreading going, but now I’m not nervous at all about the next few appointments I have in the coming weeks. After a pretty horrible experience with my previous dentist, my faith has been restored!

Everything about this office is great! Came in for a wisdom tooth removal and deep cleaning. Best experience by far. I felt completely comfortable and taken care of. Dr. explains all the work along with pros and cons, and the staff make you feel welcomed always.

I have been going to the same dentist for almost 3 years now and I couldn’t happier. The knowledgable Dr. K has been doing a great job in making sure that my teeth are all in good condition. He always gives the best advices and will explain to me patiently what needs to be done and what is the best options for me. When I first visited them, I was so afraid, but he was so understanding and gentle; he will crack jokes and reassuring me that everything will be fine. Not only him, the rest of the staffs are also extremely friendly and they are always more than happy to help me in settling my insurance issues. Some of the staffs even cheered me up each time of my visit, assuring me that I will be ok and I have been doing alright. Makes me feel that I am not alone going through some scary processes. Thank you, Dr. K and the rest of the teams. You have made my dental visits a pleasant onesss. I still do have fears sometimes, knowing what kind of complicated job I am about to go through, but I am no longer that afraid anymore  =)
