Kourosh Zarrinnia DMD MS

About three years ago my teeth were in the worst shape possible ! And Dr Zarrinnia made a huge chance to that! It was the best experience going to his office with his amazing staff. They treat you amazingly. He is by far the best orthodontist in Southern California. You will not be disappointed with him I promise!!! ¹⁰⁄₁₀ recommended forsure

Savannah and I are so thrilled her teeth look beautiful thank you so much, I recommend anyone to try Dr. ZARRINNIA. He is great and his staff are all sooooo great… Thank you. Especially Julie !!!
You are definitely an asset to that office.

I was told for years by different Orthodontists that I needed extensive surgery on my jaw to fix my bite and I new I never wanted to do that. My dentist Dr Wallman referred me to Dr. Zarrinnia because she thought so highly of him and boy was she right! He fixed my bite without surgery and just 2 years of braces. I had given up hope of ever having a perfect smile and thanks to Dr. Zarrinnia, for the first time in my life I am confident with my smile. Dr Zarrinnia and his staff were extremely gracious, accommodating and knowledgeable. I highly, highly recommend them!

I first came here over more than two years ago and was in desperate need for braces. My teeth were definitely not in the best shape and I was in quick need for change. Dr. Zarrinia made that change happen! After having braces on for over 2 and a half years I can honestly say that I am astounded by the results. I just got my braces off yesterday and have been getting compliments left and right and I can not thank these guys enough!
Definitely would recommend because the results are jaw-​dropping and at the end of the day coming here was just beyond worth it! The entire staff treats you with great respect and are extremely nice all-​around. ¹⁰⁄₁₀ would recommend.

My braces have been off for about 6 months now and I continue to receive great compliments on my smile, thanks to Dr Zarrinia! Frankly, I wasn’t expecting to continue receiving such outstanding customer service post-​treatment but I have been more than impressed. I’ve had a few follow up visits since my braces came off and the quality of care hasn’t diminished.
My dentist, Dr Kerry Chan, referred me to Dr Zarrinnia about 4 years ago. Prior to that I had given up on braces. My previous orthodontist had told me the only way to correct my bite was through surgery, I was to have my jaw broken and wired shut for 8 weeks. At that point, I no longer cared to correct the problem. Dr Zarrinia reviewed my case and told me it was worth a good shot hopefully without surgery.
As he predicted, 3 years after the treatment, my previously misaligned teeth now afford me a uniform bite. He wasn’t just focused on the mechanics of realigning my teeth, he was equally attentive to the aesthetics. And this was all done without surgery!!!
The office staff have also been outstanding (both past and present). Laura is very nurturing and goes above and beyond. Julie is awesome, she is always courteous and helpful.
I recommend this practice to any adult, actually to anyone of any age in need of orthodontic work.

I honestly can’t think of a single negative thing to say about Dr. Zarrinnia or his staff.
I’m 21 and when I realized that I would need braces, I assumed it would be an absolute nightmare. I couldn’t imagine something more embarrassing for an adult… To my surprise, however, the Dr. Zarrinnia has made this process as painless and easy as possible. I HIGHLY recommend going for the white ceramic braces– they’re a little pricier but also far less noticeable.
The doctor has been nothing but kind and accommodating since day 1. They are always flexible when it comes to scheduling appointments. I am in and out of the office relatively quickly.
THE VERY BEST PART: they are willing to take out my wires for special events or whenever I need them to! In the last seven months, I have already had my wires taken out 4 times (senior portraits, birthdays, graduation, etc.) The white ceramic braces are virtually invisible without the wire. I’m 100% serious you can’t even tell there are braces on in pictures.
Overall, I HIGHLY recommend this office if you are looking for an orthodontist for yourself or your kids. They’re really great here. I’ve still got over a year to go but honestly my teeth are already noticeably straighter.
5 out of 5, great doctor, amazing staff, put simply this place is great!

My daughter got her braces on 2 yrs ago. So far we r very happy with the Doctor and his staff!!!

I had been going to Dr. Zarrinnia for 5 years. I am a teenager who had very horrible teeth in my preteens. As any other kid, I immediately thought «oh no, a dentist. Why?!». Dr. Zarrinnia changed my perspective of dentists. When I first walked in, I expected there to be scary posters on the walls about consequences of not brushing teeth and all that. But there was nothing of that sort. The ambiance of the place was light and calming. As I was getting evaluated, a man just got his braces off and he was smiling like he just won the lottery. That reassured me that all dentists weren’t scary. The doctor himself was very kind, and soft-​voiced. Whenever I had to go back to the dentist, I would feel kind of excited because I was sure that none of my friends had such an awesome dentist like Dr. Zarrinnia. His staff is also very top-​notch. They are very friendly, fun, professional, and catered to my every dental need. A few weeks ago, when I took off my braces. Interestingly enough, a child came in with his parents for an evaluation, which was the same scenario I experienced a few years back.
Overall, I enjoyed my experience with Dr. Zarrinnia. I highly recommend him to anyone who doesn’t feel comfortable with going to the dentist. The doctor and his staff all know what to do, and how to do their jobs accurately and efficiently.

Dr. Z is a great orthodontist. Both my sons 13yr. and 28yr. old, got there braces from him. My older son liked Dr. Z a lot and recommended him for his little brother. My younger son always looked forward to all his appointments, and we were able to see him within a short notice if we needed to. The front desk assistant is always friendly and she gives you follow up appointments according to your schedule. Dr. Z knows what he is doing and is always in a good mood. Both my kids got there braces off and there teeth look great. Thank you Dr. Zarrinnia!

Dr. Zarrinnia is a great orthodontist! He always makes me feel comfortable and explains the steps for my teeth as he goes along the process. The doctor is a very nice a friendly man. I already got my braces off and the final result looks fantastic.

It’s really hard to find a good dentist that you can trust, so if you are in need of a great and professional who knows what he’s doing then Dr. Zarrinnia is the way to go. My friends always say they hate going to the dentist, but I actually look forward to it because Dr Zarrinnia and his staff are very friendly. My mom took me here to get my braces done because Dr. Roginson had promised her that I was going to be in good hands with Dr. Zarrinnia and he was very right. I started my braces in the summer of 2011 and just had them taken off August of this year. Dr. Zarrinnia and with the help of his lovely staff (ESPECIALLY Laura) did an amazing job. The office is very clean and everyone is very professional. Dr. Zarrinnia and Laura definitely payed close attention to my teeth and showed that they care a lot about their work. I thank both of them so much for giving me an amazing smile that I will cherish forever.

Dr. Zarrinnia is awesome. I originally went to this office location about 16 years ago when I was in sixth grade and it was Dr. Roginson’s office. My entire family goes to this office! Over the last couple of years I have frequent appointments to check on my teeth and my retainer. Don’t want to waste my parent’s investment years ago and thank Goodness they got me braces — an awesome smile is priceless!
Anyways, Dr. Zarrinnia is really cool and when I first went in the office to meet him I did a little bit a research on their website (
) and saw this guy has gone to the top schools, so I felt super confident in his credentials. Plus I know that Roginson built an awesome office that was high recognized in the community and across schools from Chaminade to ECR, Calabasas, etc. Roginson wouldn’t just pass along this great office with the great team so that made me even more confident. Laura, who is the best, has been working there since I got my braces 16 years ago! She is awesome, I would bring my own kids to her, I love her — make sure your kids get her!
Well, I had an issue with my retainer, I lost them! So Dr. Zarrinnia helped me out to take me from the old school Hawley retainer to the new plastic, clear ones. He told me everything about it, the pros, the challenges, and spent a lot of time with me while I sat in the chair to explain how it works. He was very strategic too in how he made my mold. I had some spacing, so he put some rubber brands on my teeth (remind you I have no braces), brought the spaces together within minutes, then fit the mold.
Further, I learned from him he actually takes cases home and studies them. There’s even a quorum of doctors he partners with and they study cases. When I heard that, that made me feel really good. Even from my retainer case, he took it home to study and think about it, he told him, «I was studying this last night, here’s what we need to do.» The issue was I had some spacing due to the lost retainers and he was going to help me close it in the most strategic way possible.
The ambience of the office is awesome. The staff is great. It is super clean, open air, and on Ventura blvd. It feels like home. Nice music playing in the background, you sit comfortably by other patients overlooking the Blvd.
It was cool to see the Doctor interact with the middle schoolers. He really thanks them for coming. Each time I saw a patient leave he said, «thanks for coming,» and he would really coach them on brushing and explain to them the importance, especially with the braces on. I saw older adults like myself visiting too!
All in all, Dr. Zarrinnia is a cool dude, and he is smart, trust what he is doing! Remember it’s not only the Dr, it’s the office staff and the environment and all together this place is 5-​Star!

My son just got his braces off today. It’s been six years since he started and I’m happy to say that his teeth look great.
Dr. Zarrinnia worked on both my sons. My older son started with an orthodontist that retired from the practice who removed several teeth before putting on his braces. While my younger son went through two phases and spent a lot of time in braces, I feel he benefitted from Dr. Zarrinnia’s knowledge and expertise with newer techniques.
Above all, I recommend Dr. Zarrinnia because he is a genuinely caring person. He has children himself and often chats with his patients to ask how they are doing. The office can be crowded at times, but the staff is very friendly and tries to move things along (especially Gail!).

Clean and nice place I got an appointment right away. Dr. Zarrinnia is very nice and very professional staff
It doesn’t get any better then him. They are always on time. You get out in a timely fashion. He knows what he is doing and does the best job. he is caring, thoughtful, honest.
His integrity unmistakably shines through in everything he does.

I am very impressed with Dr Zarrinnia. He really cares about his patients.
In this fast pace world it is refreshing to find a Doctor and his staff who are so connected to their patients. I am looking forward to a great result for my son with this new braces. Please feel free to look at the Video I created for the Doctor

I am so thankful to have found Dr. Zarrinnia and his great staff. But Gail really went the extra mile for me. I made the mistake of paying out of pocket for services that could have been covered by my insurance. I was telling Gail about it one day and thought it was just money lost… an expensive mistake to learn from. But Gail went to work and repeatedly called my insurance company. Three months later she called me to say, «we have your check in our office.» I COULD NOT BELIEVE IT! Thank you again Gail for all your help. I have found Dr. Zarrinnia’s office to be just a great group of people that really go above and beyond for their patients.

I am a doctor myself and send my kids to Dr Zarrinia. I’m very happy with his services.

My daughter is her patient and considering that I am dentist myself he is doing a great job, his staff are very friendly and his patients love him.

i would strongly advise anyone thinking about going to him to find someone else ! I went to Dr. Rogenson when I turned 50 and three months later he decides to retire, leaving me high and dry and gives his business to Dr. Zarrinnia. I had no chioce but to go to Dr. Zarrinna unless I wanted to pay more money to a different orthodontist. I never had the opportunity to have orthodontic work done when I was younger. I have always wanted to have my teeth strait. My experience with Dr. Zarrinnia’ work was not good to say the least. He didn’t seem to pay attention to what he was doing with my treatment. There were a couple of times he would say it’s time to take the braces off and I would have to point out to him that these spaces were not there before or the teeth have not moved to the way the braces are supposed to move them? Then he decides where there was a little chip in the corner of one of my front teeth to grind from that point (inside the two front teeth) to the other side of the tooth on both front teeth, giving a arc appearance to my two front teeth and damaging a strait line appearence. I had to go to my Dentist to correct the dammage. He also had a retainer made with a spring in it to correct a tooth that was never moved by the braces. That retainer did futher damage to my tooth by pushing it upwards into my gum. Now besides having my two front teeth bonded to give me a strait line I had a venner put over the front tooth that was pushed upward into my gums. The orthodontic work he performed on me was to say the least was done in a incompentent way. I wish I could get my money back.
