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

Ive been going to Dr. Warren since I was about 11 y/o and they’ve been nothing but nice to me. I didn’t finish the treatment the first time so I waited until I was 18 to get braces again. I had an underbite and my jaw had not grown correctly but he told me all of my options and I couldn’t be happier with my teeth right now. I no longer have an underbite and I had surgery on my top jaw to expand it and move it forward (thanks to Dr. Warrens recommendation) I didn’t have any pain after wire adjustments and setting appointments was not a problem, plus all of his staff are really friendly, I would 100% recommend.

My daughter Greta is a patient of Dr. Warren’s and we have been very happy with the treatment she has received. Some of the recent comments posted on this site do not speak to the wonderful and professional experience we have had with Dr. Warren and staff which is why I felt compelled to write a review. I have always found the staff to be helpful and friendly and the front office staff a pleasure to work with. My daughter’s orthodontic work is coming along nicely thanks to the work of Dr. Warren. We have been very satisfied and I would recommend this office to any of my friends looking for an Orthodontist in San Franciso.

As someone in her late 30’s, I wanted straight teeth but wasn’t excited about the idea of braces. I finally convinced myself to get Invisalign, and went to Dr. Warren. He did a fantastic job – my teeth look better than they have in 20 years! He is a perfectionist, and it showed in the results. Not only that, but I found Dr. Warren to be personable, receptive to my concerns (e.g., removing the button on my front tooth after it was no longer needed because I didn’t like how it looked), and enjoyable to visit with overall. I highly recommend him!

Dr Leonard Warren (retired) was my orthodontist when I was younger and now that I am adult I went to Dr Fred Warren for some refining work after not having worn my retainers for years! Both Doctors are absolutely the most talented, kind and great communicators! The staff is awesome and I always enjoy their beautiful office. Thanks Dr Fred and team!

Jane H. from San Francisco, CA (Source: Yelp)


Dr. Warren is a great orthodontist. He’s guided my daughter’s teeth to perfection over the last few years. Prior to treatment, he clearly explained his recommendation, and provided a sensible plan and a complete price (yes, orthodontics are expensive, but we interviewed three practices and prices were about the same, but the treatment approach varied considerably). From there, he executed as promised. I’ve always found his staff and him to be kind, accommodating and generous with their time. I’ve probably referred 6-8 families, and they’ve all been happy.

My daughter needed braces and we went to Dr. Warren based on a recommendation from a friend.  I was very happy to have found him.  The advice and options given to us were very helpful.  They explained the different treatment types and options both in person and with a video overview, as well as financing options.  The service is fantastic with no wait times in the office, reminder phone calls for appointments and a staff that’s friendly and helpful.  Their office is clean and modern.  Would definitely recommend to anyone looking to get braces for their kids.

Nancy L. from San Francisco, CA (Source: Yelp)


Both my young teens have been patients of Dr. Warren’s for several years now. They have both had braces and retainers. Dr. Warren has a lovely disposition; he’s warm, engaging and always positive. His bedside manner for kids is terrific. My daughter is fairly fearful, and he was great at putting her at ease. She also needed some extractions, and Dr. Warren efficiently coordinated what was required with her dentist. The front desk staff, financial person and nurses are all wonderful. They’re mindful of accommodating kids and parents’ schedules, and are pretty flexible when you need to make a last minute change. They’re also very responsive if you have an issue and leave a message – they get right back to you. I highly recommend Dr. Warren and team’s services.

Alex S. from San Francisco, CA (Source: Yelp)


I’ve been recommended this place by my general dentist. There’s a free orthodontic consultation, and the wait isn’t nearly as long as some other places that offer free orthodontic consultation, like western dental (Which i advise against going there for anything). I’m glad i got my consultation here, even though the prices were quite high. But there is a plan through their office which one can pay monthly over 2 years. Satisfied.

Peter P. from San Francisco, CA (Source: Yelp)


Dr. Warren  is an awesome orthodontist !  All three of my children has had treatment from him!  His office staff are all very  courteous and helpful.  They always worked around my very busy schedule .  And the end result I have three teenage daughters with the most beautiful smiles  🙂

Julia W. from Charlotte, NC (Source: Yelp)


Dr. Warren is amazing! If I could give more than five stars I would. He takes his time explaining your treatment plan. Is willing to answer any question, no matter how many you have. Dr. Warren is a joy to be around, he makes going to the orthodontist enjoyable, he is so sweet and takes his time to make sure no mistakes are made. It is clear he will do everything in his power to make sure the patient is happy. His office staff is so sweet and helpful! I would never go to another orthodontist and will take all my children to see him!

Alison L. from San Francisco, CA (Source: Yelp)


We love Dr. Warren.  My two girls are patients now of the son, and my adult stepchildren went to the father when they had their braces.  We live in the neighborhood and it couldn’t be more convenient.  Plus the pricing is painless, and the service great.  They are the most efficient office of any kind that I have dealt with in quite a while.  They have it down to a science.  And kids are so funny about predictability.  My oldest girl just has a retainer now, but we’re heading for braces soon and she loves going to Dr. Warren.  From the neato computer check-in service in the lobby that she has mastered herself, to meeting with Dr. Warren and telling me about all his jokes after her appointment.  It’s helping pave the way for the little one when she gets so far.  Who knows?   Maybe our grandchildren will be the next little Dr. Warren patients!

We researched and interviewed several orthodontists. We heard about Dr. Warren and his staff because pretty much every kid at our daughter’s school uses them. We were impressed with the diagnostics, price quoted and knowledge. We also have enjoyed the professionalism, and attentiveness, as well as the accommodating staff. We’re nearly done with our brace experience and we are on target!

A. K. from San Francisco, CA (Source: Yelp)


Went through Invisalign several years ago with Dr. Warren and have been beyond happy with the results.  I had to recently visit the office again because my upper retainer cracked (my fault). I was reminded how smoothly the office runs.  The staff and the entire dental team are incredible and it’s always a very enjoyable visit.  Didn’t think I would ever write something like that back when I was 10-12 years old with head gear!!  Love Dr. Warren – he has a great manner and it’s easy to talk with him about any concerns or questions.

Cons N. from San Francisco, CA (Source: Yelp)


Dr. Warren and his team are the best! They are professional, helpful, courteous and super awesome with my little guy. He thoroughly worked with us for a year, explained what was going on or what he’s waiting to happen with my son’s teeth. And after a year of visits and check in’s, we’re finally starting phase 1. His team is really knowledgeable and professional. Carol made the payment process seamless, she answered my million questions with a smile, offered to check out options with our insurance, overall she made sure that we were take care off! To add to that she emailed me the same day with more answers to my questions! What a team this practice has, I highly recommend them. They are there for their patients, and they ALL do it with a smile!

This is a state of the art beautiful office overlooking wonderful West Portal, it’s bright and cheerful, and the open concept is spectacular. Everyone working is a rock star and so professional. I’m overjoyed my daughter is getting Orthodontic treatment here. Five Stars �����

For the record, Dr. Warren has treated my son through multiple rounds of orthodonture due to his very complicated case exacerbated by very unusual late adolescent/early adulthood growth in his cranial and jaw structure, AND he treated me with Invisalign. Suffice it to say, we have had considerable experience with Dr. Warren and his staff from diagnostics through treatment. Dr. Warren is one of the nicest, most honest, and caring individuals on this planet, and his demeanor, integrity, and quest for perfection in his treatment of patients drives how his staff functions. If it is challenging to obtain an appointment with Dr. Warren, it is simply because he is one of the best in his profession, and is in high demand. My personal experience has always been that his staff has gone out of their way to try and accommodate my appointment needs. If a round of orthodonture takes longer than expected, it is likely due to the fact that Dr. Warren doesn’t settle for mediocrity in his patient’s results. This was demonstrated to us in our experience with our son’s case, and then again with my Invisalign treatment. The treatment plan prescribed by Invisalign called for a defined number of treatment rounds. As we approached the end of those rounds, Dr. Warren told me that he felt we could achieve an even better result if we extended several more rounds, which we did. The end result was visibly better — proving that Invisalign’s computer modeling and their treatment plans can be improved through modification and interpretation by a skilled diagnostician. The additional time with Dr. Warren yielded better results. Unfortunately, we live in a world that is filled with consumers who feel that the world revolves around them, who want whatever they want whenever they want it, and are quick to criticize others when they don’t capitulate to their perceived needs. Those people should probably consider a less skilled orthodontist who is in lower demand and who doesn’t take the time with patients practiced by Dr. Warren.

I just assume that the person giving Dr. Warren bad reviews missed and appointment and was not able to reschedule during school hours. I have never had this happen personally but I’ve  seen the sign. Dr. Warren is amazing! Not only because I used to be sniggle toothed and now my teethe are straight, but because of the care and compassion I’ve been shown here. Every member of his staff is warm and out going. I’m guessing it’s something he pumps through the air ducts, because his staff is always in a good mood and happy. The billing department is knows what their doing! I’m just about to get my braces off and I’m so happy I chose DR Warren. I went to several Dentists in the area and he was really the only one recommended. He is also fabulous with children. Yo sit in an open room, so you get to see him interact with other patients. DR warren is so warm with his younger clients. I could not think of enough nice things to say about this office, but needles to say I’m very happy about my outcome!

John H. from SOMA, San Francisco, CA (Source: Yelp)


I give my highest recommendation to Dr. Warren and his amazing staff.  I am an adult patient who had a complicated issue (now resolved). Dr. Warren and everyone in his amazing office treated me with great respect, provided honest and accurate information in my treatment plan and communicated with me clearly at every step along the way.  The office is nothing but uber-efficient.  I was never left waiting for an appointment and their hi-tech approach to record-keeping meant that no matter who I spoke with, they were knowledgeable of my issues. I was always in and out in the time frame that they specified – an important consideration for someone as busy as I was during the time of my treatment.  Best yet, his office is on the M line so all was easy.  I haven’t read any other reviews here; in fact, I don’t do Yelp often, but my experience with Dr. Warren’s practice was so over-the-top positive that I had to leave a few words.  Seriously, you can’t go wrong by having Dr. Warren take you through your treatment. And did I say complicated issue resolved?  Yes.

Catherine S. from San Francisco, CA (Source: Yelp)


I am so thankful for Warren Orthodontic. The level of organization at this office in INCREDIBLE. I appreciate the reminder calls, the emails and all the ways they keep treatment on schedule for this busy (VERY busy) mother of four. Very impressive. Dr. Warren is super – and helps the kids take responsibility for their part in successful treatment. My 17 year old might forget to take out the trash, but he never forgets to wear his retainer. Thank you Dr. Warren and your entire Staff. Much appreciation!

Benzee B. from South San Francisco, CA (Source: Yelp)


My regular dentist recommended Dr. Warren and said he sends his children to him. You know an orthodontist has to be good if a regular dentist will send his kids there. Dr. Warrens is fantastic, his marketing plan is superb, and his reminder phone calls and emails are very welcome. I’m not sure who set up Dr. Warrens support staff but they should be given a bonus. Everything about Dr. Warren and his staff receive an A+ in my book.

Lindsay K. from Hayward, CA (Source: Yelp)


Dr. Warren is the real deal!  As an adult with seriously messed up teeth, I went to numerous orthos to get initial consultations.  I felt very comfortable with Dr. Warren and his treatment plan, his pricing was about the middle of the range of other pricing that I got.  His quality of work was excellent!  My teeth turned out beautifully, i really couldn’t be happier with the results.  Everyone else in his office is very good too.  I almost always got seated right away, there was probably only one or two times where I went in and had to wait a bit, but that was during school break, so the place was full of kids.  He has some great skills and was always willing to answer all my questions thoroughly (i was very fascinated with the whole process of moving my teeth around, so i was always asking a lot of questions).  One of my best experiences with a medical/dental professional I would say!
