I’m the last person to go to a dentist, but boy did Dr. Sadri do wonders. I never thought I’d go to the dentist twice a year. Who needs to right? Well, let me just tell you, it’s important. Dr. Sadri helped me restore my smile when I needed it most. Teeth whitening, stain removal, chipped tooth repair… he did it all! I always wait until the last minute, so it meant a lot to me when Dr. Sadri and his team always found a place to fit me and and help me with exactly what I needed! I definitely go to the dentist routinely now. Thanks Doc!

Dr. Sadri, is kind, gentle, super knowledgeable and works within your budget whenever possible. It had been a long time since I’ve been to a dentist, because like others I don’t enjoy the experience. When I absolutely had to have work done I was fortunate enough to find Dr Sadri and hope to keep him as my dentist permanently . Great staff, but better yet awesome Dentist, Dr, Sadri. I went in with a chipped front tooth and he magically fix it in 20 minutes. No needles, no pain,. You’ve got to check this dentist out.

Hands down the best dentist I’ve ever had! Laser dentistry is pain free, Dr. Sadri is delightful, the entire staff is super friendly, and my special needs kids love it too!

Tina K. from Irvine, CA (Source: Yelp)


I had to share my experience about my cleaning, I’m a mom of 2 young boys and love that I can schedule a cleaning every 4 months and be in and out within 30 minutes like clock work! I feel like a VIP with every visit and am excited to try my new (…) gum gel! I’m into anything that will give me healthier gums and a fresher mouth!!

(…)I’ve been coming to Foothill Smiles for a few years now and can honestly say that they’ve earned my business for life. Besides the great and painless work that Dr. Sadri does, they go out of their way to make your experience a very pleasant one. You won’t be treated like a number or “just a patient” at this office… which is why annual checkups/cleanings feel more like a visit with old friends than a “dentist appointment”.

I also believe that a person can be only as good as the kind of people that they surround themselves with. From Michelle in the front to all of the staff in the back, it would be hard to find a better mix of good people.

Would HIGHLY recommend coming here to anyone in the area that’s looking for a great and honest dentist.

I am a new patient of Dr. Sadri. We had a long-term relationship with our previous dentist, but when our insurance stopped covering them so I started looking around and found Dr. Sadri. I brought my son there first and my son immediately loved him so I decided to be his patient, as well. As soon as you get into their office,you are greeted by a wonderful lady named, Michelle, who was very friendly and professional at the same time. The waiting area is very clean and beautifully decorated (even has coffee for anyone who wishes to have them). Frankly, you won’t need the coffee because you won’t even have time for that, since they are very good in not having you wait at all. Dr. Sadri is very thorough in everything. He will explain in detail what a patient would expect for the procedure he will perform – even the slightest detail of how the x-ray or cleaning will be done. Dr. Sadri immediately made me and my son comfortable in most of what we think is a “scary” environment. He made sure that we were comfortable and you would never think you were in a dentist’s office. He is very friendly and has that smile on his face and always asks you “are you okay”, just assuring (me) the patient is not in any pain or any type of discomfort. He used (a type of) laser treatment to remove the decay on the tooth in preparation to fill my cavity instead of the old-fashioned drill. No pain at all and the best part is that it was done so quickly. No numbing with needles. No need for that at all. Overall, I would rate him as 10 on a scale of 1 to 10. I would definitely recommend Dr. Sadri to anyone looking for a great dentist!

I was bit nervous when i first walked into Dr Sadri’s office. But everybody at Foothill Smiles are very friendly, attentive and punctual especially Regan who assisted me through all my appointments. I have had very painful experiences in the past but Dr. Sadri and his team did an awesome job. All my appointments went very smoothly without any pain at all and the outcome is really nice. I am glad i made the decision to walk into their office and I think Foothill smiles is one of the best Dentist offices in the Lake Forest area.

Roy R. from Mission Viejo, CA (Source: Yelp)


I have been a patient of Dr Sadri for over 7 years. He only does dental work (fillings,etc) when it is absolutely necessary.  His staff is very caring and attentive. I always could not tolerate  night guards. However, Dr Sadri made me a special night guard which is ultra thin and  I am  extremely happy with it and have been using it since.
Thank You Dr. Sadri

Dr Sadri has been our Doctor for many years and we’ve been always very happy. He is very caring and extremely gentle with his work, I recommend him to my family and friends all the time. Also his staff are very nice and professional. They are also Open on Saturdays which makes it very convenient for my schedule.

Andrea C. from Laguna Niguel, CA (Source: Yelp)


When I hear the word ‘dentist’ I automatically associate it with pain. I will avoid the dentist at all cost. However, my insurance was ending and so I did a quick google search for dentists in my area. A little hesitant I find Foothill Smiles phone number and call. Not only was Michelle very pleasant to talk to but she was very knowledgeable with the services needed. I set up my first appointment. When I met Dr. Sadri, he was very friendly and caring. I have never met a provider who cared so much about his patients and didn’t try to sell me on more services that were needed. I felt absolutely NO pain and walked out of the office knowing exactly what services were rendered. Needless to say, my whole family loves Foothill smiles and we have recommended our friends. This is the place to definitely go to.

Rhonda R. from Foothill Ranch, CA (Source: Yelp)


Dr Sadri is hands down the best dentist I have ever been to. I have been to some good & some bad dentists in the past. No one compares to Dr Sadri & his staff. Everyone is so friendly & helpful. Dr Sadri really cares about everyone that walks through the door. He goes above & beyond for his patients. I highly recommend him & his office especially if you hate going to the dentist. It will change your view on going to the dentist in a good way! Thank you Dr Sadri for taking such great care of me & my family!

Mike M. from La Mesa, CA (Source: Yelp)


I’ve been looking for a dentist in the area for sometime now. I moved here from the valley and was tired of driving up there to see my regular dentist who I’ve been dealing with for years. I’ve talked to people who live here and everyone’s dentist sounds mediocre. Decided to try this place and I was very happy and surprised. I haven’t been to the dentist in some time now and was expecting to hear about all the cavities I needed to get fixed and all the money I was gonna need to spend. It was the exact opposite. No pressure, didn’t make a big deal out of anything. Prices were just right, especially for someone without dental insurance. New client forms were quick and easy to fill out. My new favorite dentist!

Annie R. from Newport Beach, CA (Source: Yelp)


I cannot recommend Dr. Sadri/Foothill Smiles enough! My husband LOATHES the dentist and after finding Foothill Smiles he actually enjoys the dentist!! They are so gentle and kind! The ladies in the front are SO nice and accommodating. They call you by your first name and are so welcoming. They let you know exact cost of procedures before the work which is so important! Plus- it’s a really beautiful/clean/nice office:)

Kathie D. from Foothill Ranch, CA (Source: Yelp)


I have been going to Dr. Sadri for years now. Michelle (office manager) is as honest as they come for billing, so I really do not understand the negative review unless the reviewer is confused by where she went.

When I have had emergencies (chip falling off, etc.), Dr. Sadri has personally taken my calls and has gotten me in right away. Always available by phone or email, and the quality of work is terrific. I wouldn’t hesitate to recommend them at any time.

Sherry D. from Irvine, CA (Source: Yelp)


Dr. Sadri and the Foothill Smiles staff are the best! I hate going to the dentist and they have made the process so easy and dare I say enjoyable that I would never go anywhere else. Dr. Sadri is extremely professional and gentle, always has a big smile on his face, and is just an all around joy to be around. He always works with me to make sure all of my dental needs are met and that I stay within budget. I’ve also overheard him working with kids a few times I was there, and he is great with them.. No surprise there! Oh and I can’t forget to mention his beautiful wife who is sometimes at the front desk and is always the sweetest! I highly recommend Foothill Smiles to anyone and everyone that needs any kind of dental work. You won’t regret it!

Great Experience…

When I initially walked in, I was greeted by a very nice receptionist. I first got my teeth cleaned. The dental hygienist was extremely good at what she does. I would say the best cleaning experience I’ve had thus far. Then afterwards I had a procedure done to my front teeth. Dr. Sadri is a true artist at what he does, he did an excellent job. I can now smile with confidence!. He was very knowledgeable with the latest cosmetic procedures available, explained each procedure with much detail. Overall it was high quality dental work; he constantly made sure I was content with the outcome. I would definitely recommend Dr. Sadri to anyone seeking dental care.

Nelly A. from Aliso Viejo, CA (Source: Yelp)


Dr. Sadri is a pleasure to meet in person and a man of excellence! You can tell he genuinely cares about his patients. When I called (during lunch time), I was expecting to be greeted by a receptionist but it was the dentist himself that answered my questions and took care of my needs! He is very hands on and takes time to make you feel important and attended to. He is also intelligent, funny and very kind!!! This is the best dental experience I have ever had and I trust all my children in his care!

Dr. Sadri is by far the best dentist I’ve ever been to! Don’t get me wrong, I don’t love going to the dentist, but it’s a necessity, and the Foothill Smiles is the way to go! Dr. Sadri was extremely gentle and knowledgeable​. I had NO pain during the entire process, ​and he did a complete job of making me feel at ease by ​explaining every step of what he is going to do and what I should expect.

On top of trustworthy service, his staff is on point, professional and pleasant. When I walked into the office, I was greeted with a warm hello and a comfortable place to relax for a moment. His assistant, Shirin is so sweet, helpful and outgoing while at the same time being efficient.

I highly recommend calling the Foothill Smiles for your next checkup appointment. Trust me! You won’t be disappointed

Susan P. from Irvine, CA (Source: Yelp)


Dr. Sadri has been incredibly amazing from day 1, I’ve been seeing him for over a year. From cleaning to fixing my old fillings to chipped tooth.
About 1.5 month ago, I chipped my FRONT tooth  from sparring with my partner in Brazilian Jiu Jitsu. The very NEXT day, I called, spoke to Michelle, she was able to schedule me in right away (Same day).
In less than 20-30mins, Dr. Sadri fixed my chipped tooth and you can’t even tell I chipped it. His work is amazing. I TRUST his work 100%
Thank you so much Dr. Sadri and Michelle!

The experience from beginning to end is like no other. The office is very professional – there is literally no wait time, no smoke and mirrors – just honest and great people. Dr. Sadri and staff and very efficient. You are told up front what your issues are, if you need a certain treatment, what you can wait on, and how to resolve issues on your own. Trips to the dentist usually aren’t very pleasant but here they’re like a dream.

I don’t usually write reviews, but My dentist deserves it. Before I came to know him, I had gone to several dentist which they all wanted to to all kinds of work that I didn’t needed and they made it look like it was critical to have it. Dr. Sadri have only done the work I needed and it was none of what the other dentists had said. He clear all my doubts. In addition, he just did a crown work and it was fast and painless, bet I ever had. I would recommend his services to anyone. Also, he is very, caring and concern about how you feel throughout every work he performs. His staff are very welcoming and sweet. His office is very clean and professional. This is why I gave them 5 stars. I wouldn’t rate anyone excellent; specially a dentist, but he gain my trust. Keep up the good work.

Armin N. from Mission Viejo, CA (Source: Yelp)


Amazing service along with the best, funniest Dentist out there Dr. Ali. The staff here is always super professional and friendly, every single time I have come here I felt like I was family. They treat everyone so good and the Dr is honest with what you really need and what you don’t so you never feel like they are trying to sell you anything or get you to do get things done that you don’t have to. Definitely recommend it to anyone looking for a new Dentist. Thank you Foothill Smiles for always being so awesome!

Elizabeth F. from Orange, CA (Source: Yelp)


Dr Sadri is amazing! I’m back after having moved 45 min north away.  My husband and I had been going to Dr Sadri for years, then moved far away.  We tried 2 different dentist near our new home and we always felt like we were in a used car lot with a huge sales pitch and they didn’t even clean our teeth- just looked at them and had to come back to get a cleaning and pay a huge amount on top of it.  Not Dr. Sadri- he is amazing!!! So we are now driving 45 minutes to use him again because we get a good cleaning every time!!! And extremely reasonable rates.  Thank God for good dentists like Dr. Sadri!

Dr. Sadri is adorable, friendly, compassionate, and puts me at ease with dental care. I trust him and his front office peep Michele whom I TRUST implicitely. Their customer service is Excellent and I always feel they have my best dental health interest at heart with sensitivity to my life needs. They converse beautifully about ranges of options, and are very responsive when one is honest about what one needs. Just sayin’!

Tina B. from Rancho Santa Margarita, CA (Source: Yelp)


Dr. Sadri and his staff always make it easy for you. They are willing to work with you, your insurance and payments so you can get the care you need when you need it. My family and I have been going to Foothill Smiles for almost three years now and have always been satisfied with the results. The facility is always clean and staff always pleasant.

James L. from Irvine, CA (Source: Yelp)


The 2 things I value in a Dentist are honesty and skill. You don’t always know about skill until after the fact but Dr. Sadri came highly recommended. Now that it’s after the fact, I can say he is good.
What I took away from him the most is he is very honest. My previous dentist said my daughters tooth needed a filing. It didn’t sound right to me because it is a baby tooth and would soon fall out. Dr. Sadri explained why it’s best not to fill it. I appreciate that.
Dr. Sadri is also passionate about Dentistry. You can see and hear his excitement to help you.
Lastly I’ll say he feels more like friend who cares for your well being instead of a business person(…)

Ramona P. from Rancho Santa Margarita, CA (Source: Yelp)


The fear of the dentist is real for everyone, especially me. The anxiety, the drills, the smell etc. The first time I came here, I was a nervous wreck. I googled just about every dentist in OC trying to find the perfect dentist. From the minute I called, Michelle got me in right away. I was in excruciating pain. She put me at ease from our 3 minute phone  call, to the minute I walked in the door. Angel! Dr Sadri is a miracle dentist. There is no pushy, you need this extra stuff. Straight to the point. Gentle & very modern. We all hate needles! His laser cavity filling is a game changer! I will never go elsewhere! You guys are the best out there!

Adam A. from Henderson, NV (Source: Yelp)


I just finished getting my teeth cleaned and a couple fillings done. This office works so fast and is so friendly! This was a painless visit that left my mouth feeling refreshed and cleaned. I will continue to come to them for dental services! Sadri is a cool hip gentleman who is a pleasure to chat with and an overall excellent visit!

Dave V. from Mission Viejo, CA (Source: Yelp)


Dr. Ali Sadri was referred to me by a coworker. I am very pleased with how he treated my situation.  He was very compassionate and thorough as well as being easy to speak with.  I am very happy with the permanent crown after my root canal.  He was also very accommodating with my financial situation as I did not have dental insurance.  I would recommend Dr. Ali for dental work.

Mona Y. from Mission Viejo, CA (Source: Yelp)


Dr. Sadri is the best dentist I’ve ever had! He truly cares about his patients and treats you like family! I have encountered many dental offices in the past that were not only inefficient, but also would nickle and dime me at every turn for sub par services. Dr. Sadri is NOT like those dentists! I initially went to him for a second opinion since one of those former mentioned dentists wanted to do a root canal on me and were charging me astronomical amounts. Dr. Sadri took a second look and said I just needed my filling refilled and he not only did a great job of painlessly taking care of my teeth but the filling looked much better than before and the services were a fraction of the cost the other dentist offices were charging! Not only is Dr. Sadri great, but his whole office staff is friendly and helpful. Michelle at the front desk is excellent! She is extremely competent and helpful and so sweet! Dr. Sadri does an amazing job and is truly an artist at making beautiful smiles. I have recommended all my family and friends to him and there is no one else I would trust with my dental care!

I accidentally popped off one of my old crowns trying to get some meat out from between my teeth using a plastic fork and when I went to check it out in my bathroom mirror I discovered that I had a cavity right next to it. I gave Dr. Sadri a call to see when he could get me in to get the crown re-cemented and he told me to come in early at 8:10 am tomorrow and he’ll squeeze me in and get it all fixed up for me. I got there early like he said and he took me right in, did an x-ray, re-cemented the crown and did the filling all in minutes. I just checked it out in the mirror in his bathroom and it looks great! The guy does great work and wastes no time, and his prices for the work are good, I thought it was going to cost a lot more than it did. I was in and out of there quick, and now on with my day. Had to stop and say thanks to Dr Sadri and let everyone know that I totally recommend this place. If you’re looking for a new dentist check this place out, you’ll love it, I know I do.

Wonderful office! Perfect place to take the whole family. My kids love it here too. No annoying TVs on the ceiling. No gimmicks and sensory-overload here! Just a beautiful window view and caring, nurturing, knowledgeable staff and conservative dentist.

Ed S. from Costa Mesa, CA (Source: Yelp)


Dr. Sadri’s office is the perfect place for all yours dentist needs for the whole family.
My kids love going there and he has taken care of many of my friends over the years.
Michelle, Ali and the rest of the staff love what they do and do it with a smile and authentic care for your well being.
Don’t have insurance? Dr. Sadri will help you out.

Dr. Ali Sadri and the team were amazing and vary understanding and flexible. My wife and I have been blessed with a two year old and a 3 week old and we missed one appointment and late to the other. They were very kind and understanding and they worked us in with there schedule and our two year old nap schedule. Also I can’t believe I am saying this but this was the best and most comfortable dentist experience in my life(…)

Cathy Newby (Source: Facebook)


I am a big fan of Dr. Sadri! He really cares about his patients, making sure they are comfortable, and is very thorough. I also left here feeling like I had the best deep clean of my teeth in my life! A big shout out to Priscilla too. Thank you.
