I've been seeing Dr. Geronimo for about two years now, and I honestly couldn't ask for a better dentist. He is not only incredibly skilled, but also one of the kindest and most genuine people I've met. He explains everything with care and only does what's truly needed -- never more. I always leave feeling well taken care of and at ease. He has such a calm, happy energy that makes even dental visits feel very comfortable. Scheduling is simple once you know how it works -- just text him, and he'll always respond when he can. I feel really lucky to have found him. read more

Was visiting my kids in San Francisco and a tooth was bothering me, my dentist had warned me it might need to be pulled. Dr. G took good care, even had me laughing after it was done. How many dentist can do that. I am so impressed with this dentist. Wished I lived in San Francisco so I could have him be my regular dentist. Awesome doctor. I highly recommend him. He was very kind and really knows his craft. He explained every step and really put me at ease. read more

What an amazing human being. My daughter had an emergency root canal . She was due to return to Australia in 2 days. We went to his office and saw it was a complicated procedure, made some calls and got us in with a colleague in an hour. He wouldn't take money for his time and was so comforting and assuring to my daughter. read more

I have nothing but praise for my dentist- Dr. Oscar Geronimo! He is truly an artist with dentistry, and provides clear explanations of work that needs to be done. He has a great chair side manner and helps me to not focus that I'm in the dentist chair- which for me is a triple plus because I have such high anxiety about dental work in general. If your looking for a dentist that knows what he is doing, gets the job done and truly cares for his patients. If you're looking for a dentist that does great work that's pain free call Dr Geronimo- he gets the job done! read more

I have been going to Dr Geronimo since 1990. He is compassionate, caring and skilled. He has taken the time to research the best treatment options for my cardiopulmonary issue. Including switching to cardiocane as I have severe reactions to all anesthetics. Highly recommend. Parking can be tricky so arrive with plenty of time to find a space. Dr Geronimo works by appointment only. read more

My teeth are pretty pampered pearls after 6 years of bi-annual visits to Dr. Geronimo. Up a staircase on Judah/45th is his small office that includes a waiting room (never had to wait) and 2 patient rooms. Not only will you be in good hands, you will be entertained by the most upbeat dentist you will probably ever encounter. He's cute too. :) After having the same depressed dentist for my earlier years growing up in the s.bay, I have to say this is a refreshing change. You'll want to lick your teeth and starve all day after a visit to Dr. Geronimo. read more

Dr. Geronimo is the best! He's just a few blocks away from my apartment, which is super convenient, but even if he weren't conveniently located for me I'd still go to him. First off, when you get a teeth cleaning, you usually feel like you've got your mouth stuck open for the entire time, with the dentist asking questions and expecting you to somehow answer while his hands are in your mouth. Well, Dr. Geronimo cleaned my teeth in small sections, so I'd only have my mouth open for several minutes at a time, and then I'd get a break while he told me about various tooth facts. He's also very entertaining! He's really funny and he keeps you interested while educating you about teeth and brushing and such. I feel like every time I go to the dentist, I hear the same spiel about tooth and gum health, and how to brush... but Dr. Geronimo gave me all kinds of new information I'd never heard, and when he did repeat what I'd heard before, he did it in an entertaining way that actually made me want to care for my teeth better. That, and I laughed so much you'd think I was at The Punchline. I didn't leave feeling like I'd just spent the entire time mindlessly staring up at the ceiling. I felt like I'd actually had a good time. AT THE DENTIST! To top it all off, he gave me a student discount ($20 off). read more

Some relationships have lasted nearly as long as my ten years in San Francisco: my hair stylist, my eye-doctor and my fantastic dentist, Dr. Geronimo. I initially went to him because he was in my neighborhood, right around the corner. I've moved around to different 'hoods since then but there is no replacing Dr. G! He is pretty darn charming and I imagine he would put the most nervous-about-dentists person at ease. It really is a one man show, so everything is done by him--this includes scheduling so just leave a message when you call (geeze, lighten up, dude-who-left-one-star-for-this) and he will get back to you. If only I got to see him as often as my stylist... read more

When I walked in I thought "uh-oh, is this a sketchy medical shakedown like that urologist I went to?" but it wasn't. It is just a low-budget operation in a good way; not trying to sell you unnecessary procedures, hooking it up with glaxosmith-kline promotional toothpaste and generally being a cool dude. Also was real friendly and not put off by my political conversation. To echo some other reviewers he was very open about what he was doing, explained what 1's, 2's and 3's correspond to and went more in-depth about the chemistry of stains when he learned that I have a science background. I stayed after chatting for like 10 minutes. Definitely the type of dentist I would invite to a party. Oh, and the tooth cleaning was done by him personally and was professional and low-tech, which I like. My teeth are beeee-youtiful and I have a realistic tooth-care plan. read more

Again, I'm slacking on putting up a good review for one who deserves it, but rather late then never. Dr. Geronimo is THE BEST. He is the super-sweetest-funniest most awesome dentist ever. And he did a great job on my teeth. I've only had the basic cleaning, but I guess that's a good thing. His office used to be in my neighborhood; I now live in Oakland, but will make the great journey over the wide bay into the avenues in order to see him again. A very kind soul. Great spirit to lift your spirits. read more

Went for my first time today and was excited I had a good check-up after not going to the dentist in...(I won't tell you how long). Although I was a little taken aback by walking up this seemingly wrong staircase thinking I was walking into somebody's house or something, I found a small, quiet office with my new dentist awaiting my arrival. He was the only person there and I filled out the forms and it was down to business. He was very outgoing and loved to converse throughout my visit. he was gentle and non-intrusive and I felt very comfortable the entire time. I also learned about my teeth as he told me what he was doing and what he saw throughout. I felt like I was just going to the neighbor's to get my teeth cleaned...interesting feeling. He was very professional and I look forward to seeing him again in 6 months (I swear!) :) that's me smiling, it's so pretty now, right? read more

Best line from Geronimo; "I really hate losing to this stuff (the build up on my teeth). Geronimo is my favorite doctor ever! read more

Dr. Geronimo is great...very cool, most laid-back dentist I ever came across..He is hilarious when he is working on your teeth and likes to tell stories..every visit is more like entertainment and laughs than a boring, serious dental appointment. He won't try to push unnecessary procedures on you, just a simple, cool, and friendly dentist.. The office is not one of those high-tech dental offices, he is the only one that works there, so usually you leave voice-mails on the machine and he will get back to you... Awesome dental visits in a stress-free environment :) read more

After reading reviews, I was very excited to find a dentist near my home that took my insurance and sounded so great. Unfortunately, I called about 6 times over two weeks with absolutely no return call. I was frustrated because the answering machine cut me off. But because the reviews were so good, I called back.. again and again...and again. Two weeks later... no phone call back. I am moving on... NEXT PLEASE! If I could give no stars... I would! read more

this guy's a riot! very personable. i call him dr. laughing gas. he makes me laugh while he's working on me. and he does good work because he enjoys his job. and he tells stories. he even took me on a saturday and cleaned/polished my tongue ring! keep a savings account though for when he actually does get around to billing you for special work. i haven't paid him a dime yet and i owe the man for 2 crowns! read more

This is the one. I don't think im switching dentists for the next good 20 years. I love Dr. Geronimo, just had an appointment with him this morning actually. Its more like going to see a friend, then to the dentist. He is laid back, chill, always cracking jokes left and right. Really nice guy, recommend him to anyone- you wont wanna leave. read more

This review was so true: "you will be entertained by the most upbeat dentist you will probably ever encounter." Not only the most upbeat dentist, but also among the most upbeat people I've ever met. I was worried at first but the fear was gone soon after meeting Dr. G. He was extremely humorous and energetic, always telling great jokes and stories and having enjoyable conversations with me. There was never one moment that I felt bored during the tooth cleaning process. Of course, he was very professional and took good care of my teeth, without any unnecessary process. He even gave me a special small toothbrush for brushing my wisdom teeth. I was kind of sad because I may not see him again. Definitely recommend Dr.G to everyone! read more

Fabulous!!! I would never thought I would use this word to describe my experience with Doctor Oscar Adonis. Wonderful personality, caring, talented.... Within 3 hours we did 5 fillings and a deep cleaning....with no pain. Very impressive #grateful read more

Ummmmm.......Why don't they ever answer the phone here???? Can anyone recommend a better time to call cause its usually an answering machine.....ughhhhh read more

I did go back to him! And he is just as fantastic. ALSO he let me choose whether or not I wanted to use Novocaine, which I hate using, so that was a bonus. read more

Dr. Geronimo is very personable and old-school. He is to dentistry as barbershop is to haircut! Which is EXACTLY what I want in a dentist! And a haircut! :) read more

Best dentist I've ever had. Little or no pain and was the only dentist who could even attempt to do dental work on my ex wife. Couldn't handle or sit in another dentists chair. Very neat personality. read more

Hated going to the dentist before. Now I feel like I have a dentist that I trust and am so comfortable with! He is patient, explains everything he is doing, gives you a full perspective of options when he recommends a procedure and all around is a fun and awesome guy! I told him a bunch of my friends were in town visiting and he gave me a tooth brush for each of them! His operation is super low key and he does everything himself, but personally I love that about Dr. G. read more

I've moved around a lot and have had many dentists in my time. Dr Geromino is absolutely incredible. Usually when I got to the dentist they don't speak much, and they do their work on your teeth and then run you off. He was never in a hurry with me. And he explained everything to me, and made me feel comfortable to ask any questions I had. I actually even learned a lot about my own teeth. This is because he was soooo personable and caring. With this guy, you know you have a dentists that cares about you. I will recommend him to anyone that needs a dentist. I also never bother writing reviews, but I was so impressed that I felt I had to. MarquS BeaN read more

Going to the dentist at Dr. Geronimo's is not like any other dental experience, and that's because it's FUN! I actually look forward to going to see Dr. G because it's like catching up with a friend - the teeth cleaning is just the bonus. Great sense of humor, always upbeat and energetic, and he goes the extra distance to do a great job. He isn't going to push things you don't need. My wife and I have been going to him for about five years and will be going for many more. read more

As soon as I enter a dentist office I usually turn into a feral cat and try to escape or hide but Dr. Geronimo was fantastic. He was able to keep me laughing and calm throughout the whole visit and no one was scratched or bitten. I left purring with my fangs nice and sharp... Thanks again Oscar. read more

Signed up for Yelp just to make sure I could add a good review here for Dr. Geronimo. I had a broken wisdom tooth and hadn't been to a dentist in 12 years -- Dr. Geronimo not only saw me on extremely short notice but he was kind, courteous, and funny. "Funny" may not be in your list of requirements for a dentist but what I mean is he is very easy-going with patients & obviously a people-person. For someone who has been terrified to go to a dentist for over a decade, that's no small thing. Best of all, of course, he fixed (read: pulled out) my broken wisdom tooth in about 30 minutes, and I felt relaxed and in good hands the whole time. He even texted me the next day to make sure everything was fine. He explained everything he was doing and made sure I was comfortable. I felt about a thousand percent better and for the first time in over a decade I'm actually planning on going back to a dentist without having a massive tooth emergency as the reason. Last note -- as people mentioned in other reviews, the location MAY be slightly off-putting. It's a hole-in-the-wall, up a narrow staircase and in a few rooms in what looks like the top of a converted apartment in one of those random Sunset buildings where they seem to put just about everything. Don't be deterred and don't worry. It's all very professional and he's a terrific dentist. read more

I love this guy. He's unpretentious, funny, and really knows what he's doing. For the first time in my life I'm going to look forward to going to the dentist. read more

Good dentist, good man. My experience with dentists in the last few years has given me the feeling that dentists are like used car salesmen: more interested in building their busienss than taking care of me and my teeth. I understand that running a dental office is a business, but I need my dentist to focus on my teeth and my health. Dr. Geronimo taught me more about my teeth in one visit while giving me a cleaning and reviewing my health status than I've learned in 50 years of going to dentists. He explained everything he was doing while scraping plaque, where things were building up, what I could do about it, how my gums were doing in different places, what a cavity meant, how they happen and how to catch them early, and options for what to do to be more healthy and keep my teeth as long as possible. Glad this guy is in my neighborhood. read more

Dr. Geronimo is so cool. He is laid back and chopped full of information. He told me I was boring and my teeth were two's and three's. This is actually good things, because boring means not too many dental issues, and two's and three's refer to the mm flap of gum that stick out. He told me how my jaw detaches at different points. Yeah, interesting. Dr. Geronimo is very professional and down to earth. I look forward to going back to him in the future. read more

Skills, personality, no unnecessary procedures or expenses-just good old fashioned dentistry at its finest! I have to say, I never really had much faith in dentists before coming into his office. He is so knowledgeable and relaxing though, and I don't think I ever knew just how clean teeth could really really feel. So clean! Yes, he's my favorite and has been for years. I recommend him to everyone (as long as he still has time to see me once in a while). ...and after a visit to his office you can always go hang out at the beach or do some good shopping at OA! read more

Dr. Geronimo became my dentist while I was living in San Francisco and commuting to San Rafael for work. I was not only pleased to find a fantastic dentist that knew dentistry in and out, but also a professional and charismatic individual. Although I have recently moved to Santa Cruz, California, I still make the long journey to San Francisco to meet with Dr. Geronimo for my six month cleanings! Highly, highly recommended. read more

I concur with everything that the other reviewers wrote. I now live in Los Angeles and travel all the way to San Francisco to get my teeth cleaned by "Dr. O." He's been my dentist for about 7 years. I'm scared to death of the dentist because some of them are just too rough. Dr. O is extremely gentle, very thorough and just a total crack-up. And he's a handsome guy too, so no need to stair up at the ceiling. He's much better to look at. He's such a cool Dentist that he's even scheduled me on a Sunday. Dr. O is super Dope. read more
