Nice and clean office. Love the doctors and staffs . I had pain over the weekends and left the message on answering machine, later the doctor returned my call. I was able to go to their other office in canyon country on Saturday. They  got me in right away and took care of my toothache.  On Monday morning staff  called me to follow up to make sure that I am fine.  I am appreciated for the caring of all the help from smile city dental. Strongly recommend  .

Without an ounce of doubt, Smile City Dental is my all-time favorite dental office. They have maintained and cared for my teeth for many, many years now and I don’t go elsewhere. The staff is excellent. They are a team of honest and caring individuals. The office and the dental quarters are all meticulously maintained down to the smallest detail. 5 stars outta 5 stars in my book.

I’ve been to like 10 different dentists in my life.. this is by far the best so far! I always hate going to the dentist.. my first trip was for a cleaning, they were soooo gentle! The next trip was unfortunately for some cavities, it wasn’t bad at all, the dr and assistant were very gentle with my teeth. Also The receptionists are super sweet!! I highly recommend this office for anyone 🙂

Chuchies S. from Lancaster, CA (Source: Yelp)


I had a toothache on my wisdom tooth and they were able to take me in fast despite the covid situation. Both receptionist were truly sweet and professional. Dr. Alexis and her dental assistant (I forgot her name ) were by far sooooo excellent! They talked to me and made me laugh. They made me feel so comfortable even though I was nervous. I just moved to the area and I’m so glad to say I found my dentist! This place has an amazing staff. I look forward to returning

The best dental practice in Santa Clarita! Always professional and courteous staff AND the dentists are top notch. Every time I go there the place looks nice and clean. Dr. Kossi always takes her time and explains what she recommends and why it’s needed, as well as what I can do to better maintain my dental health. Thank you Smile City! You guys rock!

George D. from Tempe, AZ (Source: Yelp)


Dr Alexi Kossi is the best! I have been coming here since I moved to California and would recommend to anyone. The staff is very kind and accommodating. My wife and I have had multiple procedures and they have done an excellent job every time. They treat every patient very well and make sure we are comfortable with all our services. Thank you Dr. Kossi, Andy and all the staff!

Luke P. from Mira Mesa, San Diego, CA (Source: Yelp)


Smile City Dental is amazing! Dr. Kim is by far the best dentist I have ever had. He is very thorough, takes the time to explain to you what he is doing, and he makes sure to inform you of your options and works with you to ensure that you are making the best decision. He goes above and beyond to make sure that you are happy and that his work is done perfectly. Dr. Lim is very honest and I have never met a more knowledgeable and trustworthy dentist. All in all, I had a great experience here and would highly recommend Dr. Lim.

Everything you’d want in a dental clinic: friendly and professional staff, excellent work, and a modern vibe. Bonus with watching Netflix while getting your teeth worked on. I would also give it an A++, a 10 rating, 2 thumbs up, etc. You get the idea. Stop reading reviews and just make your appointment here, already. You can thank me later

Chris Herring (Source: Google)


My wife and I have been going here for years and we’ve always had a great experience. We are seen promptly at our scheduled time (or before) and everyone is nice and professional. We’ve moved from the Santa Clarita valley to the San Fernando valley but still come here for all of our dental needs.

Michele M. from Valencia, CA (Source: Yelp)


My new dental office!! My old practice moved locations & this one has been under my nose the whole time! It’s around the corner from where I live & work. Very impressed with the entire staff from  Cheryl at the front desk all the way to Dr. Kossi in the back. They take their time with you always assuring that you’re comfortable throughout. I’ll be recommending this practice in the future! 🙂

Carla T. from Valencia, CA (Source: Yelp)


At 52 I’ve been to dozens and dozens of dental offices in my lifetime but I’ve got to say this one is my favorite.  The office is attractive, calming thanks to the water fountains, and the staff are ALWAYS terrific.  Shout out to Suzanne for being such a doll to me while cleaning my teeth and the highest shout out to Sara who is a treasure to work with.

My Favorite dental Place. Excellent place for my deep cleaning and crown. Even though I live in Downtown LA but I still drive here because it’s worth it. Their staffs are very nice and friendly. Dr. Alexi Kossi is my favorite dentist. She takes good care of my teeth. She only recommend the stuffs that you really needed. I feel that she is very honest person. She won’t ripped you off. I don’t have insurance but their price are affordable!! Their place looks professional, clean and comfy. They have good movies for you to watch so you won’t get bored while you are on service. I recommend this place for everyone who seek special care and attention. You won’t be disappointed. I always come here for all my dental services.

I just recently had a handful of Cavities filled. Normally the dentist is a long and annoying experience, but smile city was actually fairly pleasant. Or as pleasant as getting a hole drilled in your tooth can be. -scheduling was easy. They put me in as soon as they could and also accommodated for a next-day checkup with almost no prior notice. -there was very minimal wait. Five minutes tops in the waiting room. -the staff were friendly and enjoyable to converse with. I felt immediatly at ease. This is very important for me, I’d like to be at ease with the person who is operating a drill inside me. -netflix in the actual operating rooms was a plus. Gotta catch up on bobs burgers some how. Although I had five cavities to be filled, the process felt over and done with very quickly. (although not compromising in quality or professionalism). I wouldn’t say I’d get cavities on purpose to go back. But if (and most likely when) I do, I’m definitely returning to smile city dental.

LOVE Smile City Dental. Dr. Kosi, staff and Andy are all amazing!!!! Before meeting this gem I was so terrified of going to the dentist. They understood my fears and took their time with me and now I’m a pro. My family and I live 3 hours away and yet we still make the drive to see them. I wouldn’t want to see anyone else other than them. Regard to COVID- They are EXTREMELY clean and follow all regulations CDC has put in place. They are truly looking out for the well being of their patients. Totally recommend them!

Janel M. from Palm Springs, CA (Source: Yelp)


I had a lot of work done today and I’m a scaredy cat when it comes to dental work! Everyone there is caring and personable which put me at ease. I appreciate that they were making sure I was okay and were very accommodating. I went to Albertsson’s afterwards, telling the cashier I just had a root canal, he then told me how much he loves it there and his wife was there earlier that day. The lady in line also assured me how happy she is to go there. I feel even better now with my choice of a dental office!

OMG! I walked in for my rountine dental appt n was greeted by Andy, the dental hygienist n was taken into this meditation room, where i sat on a massage chair w/soothing music n aromatherapy!!! WOW! at the dentist!!!

I was referred to this place by a co-worker and it has completely changed my perspective on what makes a good dentist. After a lifetime of struggling with dental issues and fear of the dentist, Dr Kossi is sweet, funny, and acutely aware of the comfort level of her patients. The office staff is friendly and supportive and works hard to accommodate everyone’s schedule and the dental assistants are all excellent as well. After a 20 years of awful dentists and bad experiences, I no longer dread going to the dentist. With their help all the previously bad work has been repaired and my teeth are back under control.

Never have I felt so happy about a dentist! Smile City, Dr. Kossi, Dustin, Andy, everyone here has totally changed my outlook. They’re genuinely kind, empathic, gentle, clean, do excellent work, and I think their pricing is very good. Im 60 years old and been to a lot of dentists, and Smile City is the best ever!

Mark Lentry (Source: Google)


My daughter and I have been going to Dr. Kossi for our dental needs for almost 20 years! The office staff headed by Andy is extremely helpful, efficient and friendly! Dr. Kossi has been amazing and professional with all the work we have had done over the years. From root canals, veneers, crowns, fillings, cleanings etc. She is by far the best dentist I have ever had! When I move from California I intend to pack her up and take her with me to wherever I go!!!

Always feel like home when I visit Smile City Dental! Everyone is so kind! The dentists are wonderful and I always feel like they are taking care of me and my teeth. They do wonderful work, from a simple cleaning, to a quick fill, I am always happy with the professional attention. Martha, the dental assistant, always puts a smile on my face while providing professional and timely work. Thank you for everything! Can’t wait to start my Invisalign treatment.

Jose V. from Acton, CA (Source: Yelp)


I want to start at the front desk. They are very professional and the customer service is outstanding. In the back the doctor(Dr.Kossi) knows what she is doing. She does a wonderful job. The dental assistants are nice and they are very knowledgeable and what they are doing. I am a very very happy customer.

Sandra Wilson (Source: Google)


My family and I have been patients for over 10 years and during this time we have received excellent service. Shortly after arriving from South Orange County we had a difficult time finding a dentist we all liked, and one of my neighbors recommended Smile City. So glad they did. The doctors AND staff are all wonderful.

Best experience in a dental office yet. The staff was very professional, friendly, and knowledgeable. I really appreciate the fact they take the time to go over your diagnosis, explain all your options, and give you an estimate for each of those options. I couldn’t recommend them enough. Thank you Dr. Kossi and the rest of your team.

Olesya S. from Valencia, CA (Source: Yelp)


My husband and son go to the office on Copper Hill because we live 5 minutes away from the office. I go to the office on Soledad. I love Dr. Kossi! She is amazing! Extremely professional to the point of perfection. She is very honest, doesn’t do unnecessary work to make money on you and explains everything in detail. She is the best dentist I have ever had. And of course what would we do without Cheryl! She is amazing, very professional, and she will take care of you in no time. Very friendly and she will do her best to make you happy. I had an urgent situation and she actually contacted other offices to get me an appointment (this is how I ended up in the office on Soledad 😉 hard for me to say buy to my favorite people Andy and Gigi, so I decided not to transfer). Every time I go to the office, I am treated like a family member. Thank you for being so awesome!

Rob M. from Valencia, CA (Source: Yelp)


We finally found a dental office in Valencia where we are not just a number.  I now have the most caring hygienist (Suzanne) and wizard for a doctor (Dr. Kim).  Alas, I always save the best for last… The front office team rocks!  I can use email to correspond about billing or schedule needs.  An all-around two thumbs UP.

Jandy Hardesty (Source: Google)


I contacted them with a chipped tooth and they got me an appointment the very next day, even though I wasn’t an existing patient. I found all the staff very personable and helpful, willing to answer all the questions I had clearly and transparently. The dentist I saw, too, was great. They also dealt well with my young daughter who I had with me, even letting her sit on my lap during the exam. Definitely glad I found this place.

Cassidy C. from San Francisco, CA (Source: Yelp)


After a toothache for a few days I called and they got me in last minute! Saw me exactly at my appointment time, started a root canal, and completely took care of the pain. Office is clean and welcoming, and staff is incredibly sweet. Cant thank them enough!

Adam S. from Santa Clarita, CA (Source: Yelp)


Beyond blessed to have found this dentist office!!! Sara, the owner, is a gem & so kind!!! Cheryl who runs the front desk and payments is also the sweetest! I don’t know why I spent so many years going to a dentist I didn’t even like!! The dental assistants I have had are all great and they remember everything about me which makes for a great personal connection. They will play music of your taste or put on a TV show for you to watch while you’re getting work done. Dr. Piltser is the dentist that has worked on me and what I like is that she always takes the time to explain what she’s doing and will even go the extra mile to take pictures with these fancy cameras to show me what she’s seeing. She works very efficiently which makes for nice visits. Gentle with the needles for numbing and always has a smile on under that medical mask! I had four cavities filled today and no pain or irritation like I have had in the past with other dentists. Dr. Piltser was able to get me to start flossing!!!! She really cares about her patients and their teeth. GO IN FOR A CLEANING NOW IF YOU HAVENT BEEN IN 6 OR MORE MONTHS; YOU WILL NOT REGRET IT!

This was honestly the best experience I’ve ever had at a dentist ever. Everyone was super kind and friendly. I just got new insurance and went in for an exam and cleaning. I had my fiance listed as my emergency contact and was congratulated on my engagement. They made me feel like a person and not just a patient. They let me pick whatever show I wanted on Netflix to watch during my exam. Dr. Lim was conversational and made me feel super comfortable. Most dentist visits I’ve had as an adult usually come with a laundry list of “essential and time sensitive” (and mind you, expensive) work I need done in my mouth, whereas Dr. Lim let me know that my teeth and gums are happy and healthy. Gave me a small list of optional treatments I could do to improve my smile, but did not pressure me AT ALL. This is all I could hope for in a dentist.

Nino B. from Burbank, CA (Source: Yelp)


So happy to have found Smile City Dental! Dr Kossi and her staff are among the most professional, caring and skilled dental caregivers around. I found the office to be extremely clean and hygienic as well. The dental assistants who do the teeth cleaning take their time and really give your teeth and gums the attention they deserve. I had Angela & Mary who were both very informative and attentive as well. Dr Kossi was extremely gentle and precise during my gum recession composite procedure. The staff is not pushy and the front desk ladies are also a pleasure to work with. I have been wary of dentists for years and I am happy to say my search is over and Smile City Dentist is where my family and I will continue to go!

I’m 40 years old and I have been Mistreated by 2 Dentists in my life so bad I have a Fear of going… Than I got a Toothache! I’m so glad I called Smile City. They got me in the next day. I was Soo scared I almost didn’t go but when I walk through the Doors, I saw the Reception ladies and they were super nice and when I went back to a room the Nurse was so sweet and listened to my feelings and assured me that I will be OK.. The Dentist I had was Wonderful… He was so busy and took the time to fit me in and he was very Nice and Gentle and had me done and out of there….Thank you Smile City! You all are just Amazing~ Keep being the Best Dentist Office Ever! Sincerely Jennifer Kim �
