Like several others who have posted, his father was my dentist when I was little. In the last few years as I was looking for a new dentist who takes Delta, I found Dr. Dean Osumi and he's been great--straightforward, kind, just a good person all around. I believe he may have relocated his practice recently which would be sad for me, but as long as it makes his life better, I wish him and his father all the best. I wish I could continue with him but I'm I think it will be a little too far. read more

Dr. Dean Osumi is a highly skilled, compassionate dentist. He is always pleasant to interact with, even if the dental procedure is not-so pleasant. I'm grateful for all he has done to keep my dental health solid as the years progress, from crowns, to fittings for the hardware needed for tooth grinding issues, and the general dental care. read more

I have been treated by Dr. Dean Osumi for 28 years, and prior to that by his father since I was a child until he retired. Both are exceptional dentists! I really lucked out...kind, listens, knowledgeable, honest, explains what he will do and does excellent work. The assistants and office staff are exceptional. read more

Dr Osumi is a rare breed. On the spectrum of old school, cares about his patients well-being. Genuine human being. Knows his craft. I'm grateful to have found him as my primary dentist. read more

Been going to him for many years. Great bedside manner. Will answer all my questions honestly. Receptionists have always been on the ball and very nice. I've liked all his hygienists and doesn't chat while he's got your mouth open. He's focused. Highly recommend. read more

Dr. Osumi is truly the best dentist ever. As a child, his father was my dentist. And I had him as my dentist until his father retired. I had switched over to another dentist who would make me do X-rays every 6 months! Once I started seeing Dr. Dean, he said there was no reason to get them every 6 months. Dr. Dean is honest, kind and always positive. He is so nice and always remembers something personal about me that I shared before. He is just like his dad, never intimidating and treats his patients like they are special. I'm so grateful for having such a great dentist. read more

Dr. Osumi is simply the best. I've gone through a few dentists since moving here from the Midwest. The dentist I went to before Dr. Osumi told me I had 5 cavities that all needed to be filled immediately. I'd never had a cavity, so I was floored. Luckily I had the good sense to get a second opinion. A friend recommended Dr. Osumi and after looking at my x-rays, he said, "There is nothing in your mouth that I would fill. You have no cavities." That was 5 years ago and I still have zero cavities. Dr. Osumi is fair, honest, and I trust him 100%. That's enough for me. read more

He doesn't take credit cards, but did a good job on a cavity I had on a molar. He might split his time at another location because he only schedules things in San Francisco on Monday and Wednesday. His father was an incredible dentist, but Dean went to UOP and also does a careful job without wasting your time or money talking about silly cosmetic dentistry. I already have beautiful teeth, thank you very much. And I am not an English Patientl read more

Dean is like a small town doctor in a big city, friendly and he takes the time to know his patients. I like to think I'll still be seeing him thirty years from now when I'm ready for my dentures. Great staff and he doesn't greedily overbook patients, leading to noisy, crowded waiting rooms like so many dentists seem to do. He explains the procedures very well and gives you options when applicable. Dean clearly values his patients and his staff. Great location above Super7 in Japan Town. You can buy a Kikaida DVD or Godzilla toy for your kid (alright, yourself) as a reward for a clean checkup. Highly Highly recommended!!! read more

Dr. Osumi has been my dentist since he took over for his dad who was the best in town. Now Dr. Dean is the best. Very pleased with him and his staff. Wouldn't even think of going to anyone else. read more

Dean is a great dentist who I have nothing but praise for. He's so good that I choose the more expensive dental plan so that my visits would be covered! I never feel like he's in a rush to "get in/get out." I don't know if he does this for everyone....but he's usually my hygienist as well. This makes me even more confident that he knows my teeth well. (meaning, he doesn't just peek in for 30 seconds, and then say, "see you in 6 months) At the front desk, Susan makes sure that I get the appointments I want....and puts up with my insurance questions (both in person and on the phone). read more

Dr. Osumi is the best dentist ever! Not only is he knowledgeable, but he really cares about his patients, explains things well, and is very gentle. If you're looking for a good dentist, you should definitely go to Dr. Osumi. read more

The best dentist ever! Dr. Osumi is very thorough and knowledgeable, and GENTLE (the most important quality for a dentist). He also went to the University of the Pacific which is one of the top dental schools in the nation. You also have the option to schedule the cleaning with a hygienist or Dr. Osumi himself which is good depending on people's preferences. His assistant is really nice and his office staff is also very kind. I wish I had discovered Dr. Osumi earlier! read more

I have been going to Dr. Osumi for 3 years now and he is absolutely the best. Not only is he caring and professional, he definitely knows his stuff and he doesn't treat you like a customer. He actually treats you like a patient. He takes time to explain things, asks you questions, asks you about your health background, etc. Since I moved here from the east coast, I had to find all new doctors, and Dr. Osumi is the only one that I can say is an absolute keeper. If you are looking for a good dentists, trust me, he is the one to go to. read more

First time visiting Dr. Osumi and his entire team and he were wonderful. They didn't rush me even though I was the last appt of the day and late due to traffic. Then the receptionist waited until I could find my insurance without complaining once. Dr. Osumi took his time first getting my history, then understanding why I wanted Invisalign, asking for other dental X-ray records instead of taking his own (more money for him!) and generally being very patient! I now know why my husband travels out of his way to come see Dr. Osumi. read more

What a terrific dentist! I was referred to Dr. Osumi by a friend who has a fear of dentists. If that's not a glowing referral, I don't know what is!! During my first visit, he took a full history, including measuring my gums and checking my bite. He discovered that my previous dentist had mis-filed my fillings, so my teeth were not meeting in the right place (totally explaining the pain on that side). He fixed that in 5 minutes, and by that night my teeth already felt better. Also, my earlier (very bad) dentist had previously told me that I need to get a full set of very expensive x-rays every year. My new dentist told me that, unless something was wrong, I shouldn't get a full set of x-rays more often than every 5 years. Otherwise, I would be needlessly exposing myself to radiation. He did the first cleaning himself and was very gentle. If I could give him more than 5 stars I would!!! read more

I just moved here from the east coast and was looking for a great dentist. Nobody could give a referral, so I took a chance and looked on yelp and decided to give Dr. Osumi a try. What a great decision! Dr. Osumi is a great dentist both professionally and personally. Professionally, he is very knowledgeable, thorough, and definitely keeps you informed. He tells you what he is doing, what needs to be done, what might have caused problems, and what the options are. And, he was the first dentist to check with me on my previous dental history so he could get the background info he needs. Personally, he is just very friendly, down to earth, and really treats you well. He treats you like a patient, and not a customer. He doesn't treat you like some doctors, who wants you to just get in and get out so he can move onto doing other things. He really spends the time with you and answers all your questions so you feel comfortable and know what is going on. Dr. Osumi is definitely a great dentist - very highly recommended! read more

I would highly recommend Dr. Osumi to anyone looking for a good, honest, caring, friendly, down to earth, professional dentist. Like one other Yelper said (which is the reason I visited him in the first place): "Dean is like a small town doctor in a big city, friendly and he takes the time to know his patients." 2 years ago I moved to SF and the hardest part about moving is finding a good dentist. I first went to Dr. Alexander Chukreef on Union Street and he told me I had 10 cavities that needed to be filled immediately! Since I've only had 2 cavities in my life and I go to the dentist 3-4x per year, I was shocked so I, like several other Yelp reviewers, went to Dr. Osumi for a second opinion. I scheduled an appointment for Dr. Osumi to look at my x-rays and give me his opinion BEFORE showing him the chart of all the fillings Dr. Chukreef ordered to be filled. Dr. Osumi was as shocked as me. We thoroughly went through the list of so-called cavities and did not find one one thing he would fill. I will cavity free. One year later (last month), I had another set of x-rays take and Dr. Osumi still states that I'm cavity free. What a relief! Thank goodness for an honest dentist! I trust him 100%. Thank you Dr. Osumi! read more

Great experience. Dr Osumi actually sits with me, patiently answers all questions, never rushes, every time. His staff is excellent and also have the same bedside manner. Scheduling is always easy. Live this place. read more

I have seen Dean Osumi since he started practice. He is a bright, gracious, articulate, kind and interested provider. He explains what he is doing and why and never oversells. I recently had a tooth crack on vacation and the local dentist wanted to do an emergency crown. I resisted and when I saw Dean he made clear that a crown was not necessary. His staff is very professional and dedicated to him and the office. Very low turnover. Everyone one I have referred has been extremely pleased by their experience. Dean is as good as it gets dental-wise. read more

I started with Dean Osumi's father when I was young. Dr. Osumi, Sr. was the best in town at the time. When he retired, I started seeing his son, Dean, who is now the best dentist in San Francisco. In 2002, I moved from the City to central Contra Costa County, but I still go to Dean Osumi for all of my dental needs. My friends think I'm crazy to go into the City, but it's hard to give up such a good dentist. You won't be disappointed. read more

Dr. Osumi is a great dentist! Whether a simple cleaning or a more time-consuming and difficult procedue, he's friendly, thorough, and honest. He seems to genuinely care about his patients. Susan at the front desk is super friendly as well and she makes paperwork (or lack thereof) a breeze. I went to my previous dentist for 25 years, until I moved. I'll do the same with Dr. Osumi. read more

The nicest dentist ever, always takes his time with you and his staff does as well. They never keep me waiting and answer all my questions patiently and thoroughly. Can't recommend highly enough! read more

I started out as a patient of Dr. Osumi's father fifteen years ago, and switched over when senior retired. I completely agree with the glowing reviews, Osumi is the best dentist I've ever seen. He's talented, honest, and forthright about your options and what he recommends. On a side note, I went to see another dentist for teeth whitening thanks to a Groupon, and he claimed to have found a cavity, even though I'd been to Osumi the week before. Total scam- a year later, still no cavity. Best dentist in San Francisco, hands down. read more

Dr. Dean is the best. I've gone to him for years for everything from cleaning to crowns. No issues ever and great chair-side manner!

When my mother use to drop me off at the dentist, I used to pretend I had my appt. and meet her at the car. She'd wonder how I got done so quickly, only to find out when the office called that I had "missed" my appt. That's how much I HATED going to my dentist. Then came the Osumi family into my life. Jerry Osumi was the first dentist who I was not scared of. Always kind and gentle. I got to know the entire family, that's another story, but long story short, when Jerry retired, Dean took over. With his beaming smile and his contagious enthusiasm for everything including to see me every time, which is NOT on a regular basis (my fault), Dean has followed in his father's footsteps incredibly which was not easy because his dad was so good. Dean and his staff, don't just care about your teeth, they care about you as a person. He always sits down and talks to you before he gets poking around in your mouth. We all know how impossible it is to carry on a conversation in a dental chair! He sets you at ease, gentle, kind, and funny. I can NOT write enough about what a fabulous dentist and now friend, Dean is! This is not biased, it's just fact! He is a GREAT dentist in EVERY sense of the word! Thanks Dean! read more
