I am a new patient at Smiles Northridge, and you can bet I will keep coming back. Dr. Sam Barkhordar is the best! He goes above and beyond for his patients. He and his staff paid attention to my concerns and addressed them knowledgeably and efficiently. Dr. Sam is conscientious and honest and explained to me the best, most cost efficient option to straighten my teeth. The staff here are also great; super friendly and warm. This is not a lazy practice at all! They are all so thorough and care about giving you the result you need and want! Plus, there is actually parking, here!

Went to see Dr. Sam after calling a number of dentists to recement a veneer that fell out (cosmetic so not covered by insurance). Dr. Sam helped me out and charged me a more than reasonable fee to fix it a the majority of dentists charged double. I was due for a cleaning and exam as well so I figured to try him out. My uncle has been a patient for years and swears by Dr. Sam and the office. He and his staff have a good bedside manner which I feel is a must in a dental office since people hate going (at least I do). I left happy with very white and clean teeth. Made an appointment for the next exam in 6 months. His office was very clean, hand sanitizer on the counter, and I was the only patient in the waiting room so don’t be scared about coming here during the pandemic. I stand by this office. =)

Just had my first appointment with Dr. Siamak Barkhordar. I was very happy with everything. He is very kind and knowledgable. He has a very gentle touch. His staff is wonderful and are angels!!! They have a nice atmosphere and will definitely go back. Thank you!

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


I haven’t been to a dentist in years and figured now that i have dental insurance why not. I was looking on yelp and saw all the good reviews and decided to try this dentist. When i walked into the door i felt very welcomed and the receptionist was great. When they called me in and i met Dr. Sam he was very friendly. He has a gentle touch and made sure that i was ok every step of the way. I would definitely recommend Dr. Sam to friends and family

My friend and I went to the doctor was very nice, funny and explained to her in detail on what he was going to do with her procedure and that I loved because not many dentist will sit there and explain to you what it is they do LOL…. ANYWAYS he starts with the procedure he finishes and she loves it Her two front teeth (centrals) looked great and so close to her shade color to plus he saved her from two veneers which would have cost her 2,000 dollars

Wonderful Dentist and very nice office staff!  I went to Smiles Northridge last Thursday to have a tooth extracted and I must say I was very nervous.  Dr. Sam and his entire staff made me feel very comfortable right away.  Dr. Sam is very professional, pleasant and patient.  He explained everything and made me feel at ease.  I would recommend this office to anyone

Glenn V. from Van Nuys, CA (Source: Yelp)


So I have done everything in my power to avoid the dentist and because of that my teeth need tons of work.  It got so bad I didn’t go because I was worried that there would be all kinds of judgement. That was not the case with Smiles Northridge.  Dr. Sam is truly awesome and made me feel extremely comfortable going to the dentist.  He is doing a great job fixing my dental problems. His entire staff is just so nice and extremely flexible.  Each time I went was due to a broken tooth or slight pain in my teeth and he has made time for me. Dr. Sam is the reason I no longer fear the dentist and will always go back /recommend him to anyone.  Top notch business right here!!

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


It was my first time here and I’m definitely coming back. Dr. Sam and his staff were all very welcoming and informative throughout my visit. Dr. Sam did my routine dental exam and cleaning. He was very thorough…he even checked my sublingual glands to make sure he didn’t feel anything abnormal (no dentist has ever done that). Throughout my exam, he made sure I was aware of what he was doing and what all the dental jargon meant. He found a few fillings that, he recommended, need to be replaced. Dr. Sam and his staff took the time to take pictures as well as explain to me why he recommended the new fillings. Usually dentists just say what needs to be done and how much it’s going to cost. He also provided me with an estimate of what the cost would be if it was not covered by my insurance. Overall, it was a great first experience and I would recommend it. Thank you, Smiles Northridge!

Going to Dr. Sam was the best choice I made as my dentist! I never experienced a dentist like Dr. Sam that is SO gentle and tells me exactly what he is doing and what to expect. Not only that but Dr. Sam cares about his patients, has affordable prices that work for me (as a student) and I’ve always been satisfied with his work! Before I met Dr. Sam I always disliked the dentist. Now I LOVE going to the dentist, because it is a gentle experience along with a very warm and friendly staff!! Thank you Dr. Sam, and can’t wait for my next visit!

Faigy K. from Tarzana, CA (Source: Yelp)


I recently went to a different dentist who repaired a front tooth of mine with a filling, one week later it fell out! I went to Dr. Sam and he repaired it and it has lasted for weeks and many more to come! His attention to detail of shaving the tooth so that it would last is greatly appreciated. He also made sure that aesthetically my teeth were up to par. I definitely recommend this practice!

Mohammad Q. from Chatsworth,  CA (Source: Yelp)


I took my daughter in today for a checkup because of her cavities. My daughter is terrified of shots, but Dr. Sam was very nice and helped her calm down and took everything slow with her. Dr. Sam is truthfully a family dentist place. I highly recommend going here. Everything is done right the first time and clean and respectfully without any problems. I will for sure be coming back again in the future to get my kids teeth cleaned and checked up again here!!

Paige Plotkin (Source: Google)


I had the most amazing experience during my first visit at the Smiles Northridge office!! Both Dr. Sam and the staff of the facility were so professional and friendly. Dr. Sam was also very honest, thorough and efficient with cleaning my teeth. He also gave fantastic recommendations on how I could maintain good hygiene management, in a cost effective manner. Therefore, I highly recommend coming here to get a basic cleaning or get other things done for your teeth.

Anonymous from Sparks, NV (Source: Yelp)


Wow, wow, wow, is all I could say!! I’m always scared of dentists and have changed my dentist at least 10 times but Dr. Sam was just amazing. He went through everything step by step and made me feel so relaxed and calm, that pulling my tooth out felt like almost nothing. I’m going to be back. Although I am writing this a bit late as the last time I was there was the summer, I just felt the need to show my appreciation to Dr Sam and his amazing and helpful staff. And just a cherry on top of it all, he has the most beautiful secretary I’ve ever seen in my whole life, its worth it to go just to see her- I think her name was Rebbeca. Hope she’s there next time I come!

Jessica R. from Los Angeles, CA (Source: Yelp)


I’ve been to many dentists and this facility is awesome!  The dentist is compassionate and explains every procedure in laymens terms so you know exactly what’s happening every step of the way. I had some deep cavities and he didn’t rush me into doing expensive procedures.  Staff is caring and very helping in accomodating me with an appointment to fit my busy schedule.  I’m so happy I found this place!

Rebecca O. from West Los Angeles, CA (Source: Yelp)


I am a new patient of Dr Sam, and I am so happy I found him; I was welcomed by a great staff, and all went so smooth. Dr Sam took time to explain in details, and found the best solution to my problem; He is a thoughtful dentist, who is such a pro! And he is very nice, which helps when you are anxious about going to the dentist! His receptionist and nurse are so sweet. It’s almost a pleasure to go to the dentist now, and for that I highly recommend going to him

Brenda S. from Los Angeles, CA (Source: Yelp)


My fear of dentists stem from lots of dental trauma in a a bike accident I experienced as a child.  However the receptionist was so kind and accomodating on the phone that i wasn’t neervous upon arrival.  And the rest of the visit was amazing! The dentist is so gentle and understanding and explained everything to me.  They definitely aim to please at this office and I’ll be coming back soon and recommending to my friends and family

Abigail G. from Northridge, CA (Source: Yelp)


Excellent service. Excellent. The receptionist was very friendly and remembered my final that I mentioned over the phone. She was very patient with my crazy schedule and even offered me something to drink. It began to feel like I was in a Twilight Zone episode, where everyone in the world is nice to you. . The waiting room was very nicely decorated and the whole place just had a warm atmosphere to it. Dr. Sam came out and introduced himself to me since it was my first time, and his assistant kept cracking funny jokes and trying to make me laugh when they realized how nervous I seemed. (I absolutely hated going to the dentist growing up, had some bad experiences). Dr. Sam was very gentle with my teeth, and you could just tell he loves what he does. And he’s good at it, you could tell that too by how efficient he is with those cavities. . But he also goes out of his way for you. Honestly, just go and you’ll see what I mean. Super nice guy. Basically: BELIEVE the good reviews about this place

Smiles Northridge is a friendly and great family dentistry. I took my daughter in today for a check-up because of her cavities. My daughter is terrified of shots, but Dr. Sam was very nice and helped her calm down and took everything slow with her. Dr. Sam is truthfully a family dentist place. I highly recommend going here. Everything is done right the first time and clean and respectfully without any problems. I will for sure be coming back again in the future to get my kids teeth cleaned and checked up again here!!! Make sure to check them out before anywhere else! YOU WONT REGRET IT!!

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


I found this Doctor based on his Yelp reviews and he did not disappoint. The staff was great and the Doctor was amazing. I get anxiety while at the dentist and he was very patient with me. He allowed me the time that I needed to calm myself and never made me feel rushed. I love how he kept giving his nurse and me encouragement by telling us that we were doing a great job. It just made it seem easier and so positive. I’m on a budget so after we went over my treatment plan we discussed what I wanted, needed, could afford and decided on what should be done first based on all that. I need a lot work and will be back as many times as I must to complete what needs to be done. He has 5 stars because he is an all around good Doctor. He is friendly, patient, kind, honest, fair and made me feel at ease. Thank you all so much!

Great family dentist!! I am so very happy to have found this place. They explain the processes and prices before they start work. Dr. Sam was do good with my 4 year old who does not like to sit still at all. I would highly recommend this office if you are looking for a good family dentist

Hantz S. from Granada Hills, CA (Source: Yelp)


I am a visitor in the United States. During my stay in the country, I got into an accident while playing basketball and broke my two front teeth. I searched online to find a good dentist to fix my problem. True enough, Dr. Sam is as reviewed. A good dentist and an even greater person. I’m sad that I only have a short encounter with him (2 visits for crowning), but I wish him the best. I highly recommend him for those looking for a good dentist around the area

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


I had a sharp pain in my upper canine. I went to many dentists who couldn’t figure out what was wrong. I found Dr. Sam on yelp. At first I was scared that he wasn’t gonna be good since I never went to him before, however the warm staff made me feel comfortable. Dr. Sam was just as nice as his staff. He explained what the pain was, pointing everything out to me on the X-ray. With his gentle and caring hands, he took care of my dental issue.  I will defenitly go back to Dr. Sam!

Rebecca Oliel (Source: Google)


Such a welcoming staff! I was impressed by the patience of Dr Sam, and how much of a professional he is. He took the time to explain all in details, and found the perfect solution for my problem with lots of honesty.Everything went smooth, and I am happy I found his practice! From the front desk to the nurse, I really feel good about treatment there! thank you for taking good care of my bridge and looking forward to my next appointment. I definitely recommend him and all his friendly team!

I don’t usually do this but I thought they deserve this. I am a 65 year old man and have never had a more professional visit to a dentist in my life. Every person, in the front and back, treated me as though they had known me all my life. The doctor truly cared about my problem and comfort which made the visit easy. I would highly recommend Smiles Northridge to everyone

Clavacia S. from Los Angeles, CA (Source: Yelp)


I loved my experience here, I made an appointment one day last year and had a flexible appointment the next day. I am in the army, as well as a full time student at northridge, not to mention i participate in school and sport events. I am very busy and nobody knows how long a homework assignment can take, however, the people at Smiles Northridge are flexible enough to work with me. With the high cost of living in California and the high cost of me being  a college student it is not easy to budget in  a necessity such as a visit to the dentist, but they went the extra mile here to work with me and they left me very satisfied, not to mention they were very polite and I felt very welcomed! I would definitely recommend to anyone trying to budget this specific dental office

I love Dr. Sam Barkhordar of Smiles Northridge. He has great bedside manners. He is nice, very kind, and professional. I saw three different dentists before I saw him. Each one of them would point out the problems in a negative and sometimes frightening way, but never provided any effective long lasting solutions, which is what Dr. Barkhordar did. He explained the problems, offered logical solutions that we agreed on, and simply fixed them. He was also very gracious for not charging the little extra amount that was not covered by my insurance. Could a dentist be any nicer? I don’t think so. The staff here is so friendly and welcoming. The practice is clean and nice. The X-ray process was quick and easy as they do it digitally. The building has a private parking lot with ample parking spots. I’m very happy to find this place. Thank you Dr. Barkhordar

Daniel C. from Irvine, CA (Source: Yelp)


I wholeheartedly agree with all the 5-star reviews here and really appreciate the full-service treatment and great customer service! For some context, a couple months ago, I recently went in to another local dentist in the Valley for a very much overdue cleaning/checkup before a big trip and was in a rush for convenience and availability.  My experience there was definitely sub-par, the dentist didn’t talk with me at all and only told me how bad my teeth were and after a full-mouth x-ray that I would definitely need a root canal…After talking with my UCLA dental student friend, he strongly advised me to get a second opinion and so after some Yelp browsing I decided to try Smiles Northridge. From the moment I stepped in the door, Sonia (the dental assistant) was extremely friendly, helpful and courteous and made me very much at ease until I left. As for Dr. Sam, he was simply awesome.  Very friendly, respectful, professional and knowledgeable.  After examining my suspect teeth, he explained to me very clearly why a root canal was not necessary based on the x-ray and the physical checks!  I definitely appreciate the honesty as it doesn’t seem self-serving as he’s not looking to go find things that are “wrong.”  He definitely exudes trust and I’m very glad that I came here for a 2nd opinion before blindly trusting that other dentist! And to top it all off, the front desk asked me if I had a great experience and were also gracious enough to provide a small Starbucks gift card for the holidays!  I really appreciate the extra mile and great customer service and will be coming back again for regular checkups!

Finding a good Dentist in the San Fernando valley could be hard. However, once I found Dr. Sam he was able to help me out with getting the best implants and crowns. I liked the fact that he was patient with me and answered all of my questions. Dr. Sam and his whole staff at Smiles are the most nicest and caring people, because they understand how important it is to have a clean, healthy, and wonderful smile. Thank you, Dr. Sam because you have given me the confidence to smile again. There is no doubt that you are a great Dentist.

I really enjoyed my experience with Dr. Sam because he takes the time to EXPLAIN to me everything when it comes to what I need for my teeth. Even before completing a small filling, he SHOWED and described to me everything he was going to do-almost a small lesson in dentistry. I appreciate that and honestly have never met a healthcare professional as patient as him and as thorough in answering my questions. I also appreciate that there have never been any hidden fees or extra charges and Dr. Sam works within my student budget. I’m really glad I found you guys, and I now consider myself a regular patient. Thanks Smiles Northridge!

I must say my experience at Smile Dentistry was amazing. The staff was more than helpful and polite. Dr.Sam was amazing with his consultations. He was informative and thoughtful. Very prompt, efficient, courteous and great sense of humor. I will definitely return to see Dr Sam!!

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


I went to Smiles Northridge to have some work done on my teeth. Upon entry into the office, I noticed how comfortable and stylish the waiting room looked.  Also, the staff at the front desk were very friendly and professional.  Dr. Sam was the dentist that wend ahead and examined my teeth. He was very professional, honest and thorough. Afterwards, he educated me on what was wrong with my teeth and further explained a cost effective and efficient way to correct the problem, where it would still look “natural-looking” and would allow me to maintain the life of my teeth.  He went ahead and finished the fillings in my teeth in a timely and painless manner. Afterwards, he took the time to answer any questions or concerns I may have had for him. I can honestly say that Dr. Sam is one of the most ethical and professional dentists I have ever had the opportunity to go to for my teeth.  Therefore, I can honestly say that from this day forward I plan on continuing to go to him for all of my concerns or basic teeth cleanings

Bret S. from Chatsworth,  CA (Source: Yelp)


We recently moved to Chatsworth and needed to find a new dentist. We found Dr. Sam and he’s great! Our family of four and even the grandparents have been going to him for almost a year now. His staff is super nice and Dr. Sam is very gentle on the mouth. He does a great job of explaining what he is doing and how much longe each procedure is going to be. He is great with kids too! My 3-year-old does well there and loves getting a rubber glove ballon afterwards 🙂

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


Dr. Sam possesses great scientific skill, art, and craft as an — Family Dentistry and Implants Specialist. Dr. Sam encompasses the perfect balance of practical, real-world expertise in dental surgery, as well as, an erudite academic background having graduated from New York University, School of Dentistry, near the top of his class. As the saying goes, ‘Compromises in life are sometimes necessary…’ However, it is important to note that: those compromises will not be necessary after visiting Dr. Sam, because he is one of the best Family Dentistry and Implant Specialists, bar none. Thank you for taking the time to read my review

Dr. Barkhordar goes above and beyond for his patients! He is patient, honest and very knowledgable. He responded thoughtfully to all my questions and concerns. The office is also well- kept and clean and the staff is warm and friendly!

Dr. Sam and his team at Smiles Northridge are like family.  They are so caring and honest and do everything to make sure I have the most comfortable experience, every-time I come in.  I have referred many friends and family.  I never thought I would say I actually look forward to going to the dentist
