I’ve been seeing Dr Rexan (she’ll ask you to call her marianna) for just over 2 years.  i finally decided to give up my beloved family dentist (from back east) whom i had been seeing since i was born because the commute was impossible.  the search for a new dentist with whom i was comfortable finally and happily led me to Union Fillmore. i can’t believe how happy i am with Dr Rexan and her staff.  i had never before received a shot of “novicane” without pain and distress.  i would NOT have believed it possible to receive this type of injection and experience NO discomfort what-so-ever.  how does she do this?  i’m not an extraordinarilly sensitive patient, but i do appreciate the extreme care Dr Rexan takes to consistently make sure i am comfortable. everyone in the office is just so NICE, you’ll feel like you’re visiting old friends in no time. i absolutely look forward to my next dentist appointment.  i love the neighborhood, i can usually squeeze in a little (window) shopping after my appointment.   the location is also very convenient, the 45 stops right in front of the building on Union!

This is THE dental office for those who hate going to the dentist. Dr. Rexan is warm and knowledgeable, probably one of the best in San Francisco. I’ve been seeing her for years and I can honestly say that I look forward to my regular cleanings! The atmosphere is relaxing and everyone goes out of their way to make sure you are comfortable from start to finish.

I have been their patient for almost 3 years, and decided to write a review since they recently remodeled. They have always been so good. Dr. Rexan is very thorough, makes sure the work is done well. She is meticulous. I don’t have good teeth, so I needed a lot of work. I had a couple of crowns and a few fillings done, and they all look and feel good. I am not afraid of dentists, but if I were, I can see how those who hate dentists can be at ease here, since the shots don’t hurt and she will makes sure you are numb, before she drills. I need to mention their hygienist Ruth. She is a little secret in town, also very thorough and extremely gentle. She rubs some kind of paste on my lower teeth, so they won’t be sensitive during the cleaning. I might sound weird, but I actually like going there, especially that now their office looks lovely!

Don’t you just hate going to see your dentist?  I use to too until I found this dental office.  Dr. Rexan and her team were all so pleasant and welcoming.. The service they provided on my teeth was even better.  I liked them so much because I felt relaxed and stress free.  They are also patient with their patients .  They were very gentle with my teeth.. The cleanings were painless and fabulous.  Invisalign has changed my life completely by giving me my confidence back. I was able to make monthly payments.  Anytime I called needing to come in I was able to come in the same day.  I have been a patient for 4 years now and I plan on staying with them for a while.  Oh yeah don’t forget the free teeth whitening.. It was so worth it.. Union Fillmore Dental they are the best!!.

I have been coming to see Dr.Rex since I was a teenager. She has always been professional, kind, and VERY EFFICIENT! I appreciate her gentle touch, the cleanliness of her facility, and the quality of her work. I look forward to visiting her each time because I know I will be well taken care of whether it’s a cleaning (my favorite), a filling, or even a tooth removal, she always does a fantastic job. I’m happy to recommend Dr.Rex for dental care. She is amazing!

★★★★★

My husband and I visited Dr. Rexan at Union Fillmore Dental today as new patients. She and her staff members, Samantha and Gina, are as friendly as can be and did all in their power to make us feel welcome and comfortable. Because the hygenist called in sick, Dr. Rexan filled in for the teeth cleanings. And, boy, did she do the most thorough job! After searching around for a new local dentist for months, I’m definitely happy we landed at Union Fillmore.

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

★★★★★

Dr. Rexan is amazing!  I moved from Florida and had the same dentist my whole life, so I was really nervous about seeing a new dentist.  The Office Manager Samantha was very helpful with answering all my insurance questions and getting my x-rays from my old dentist.  Gina, Dr. Rexan’s assistant was very friendly and fast when she took my x-rays.  Dr. Rexan answered all my questions and explained everything to me in great detail.  We went over my x-rays together and no cavities!!!! Donna the hygienist cleaned my teeth and was very gentle.  Now my teeth are squeaky clean! 🙂  I found this office on yelp and did my research with several offices  because I was so nervous.  I made the right decision!  Highly recommend this office!

Going to the dentist was never an easy task for me- in fact, it was always terrifying, until I decided to go to Union Fillmore Dental. My coworker had a lot of positive things to say about this place and I finally had the chance to check it out. From the front office to the Dr. Rexan’s dental team, I felt right at home. They made sure I was comfortable during X-rays, asking me continuously if I was ok during the cleaning and polishing, and the consultation was very detailed and thorough. I did not feel like I was being rushed out the door like some dental establishments. Although I live in Daly City, this brief drive is worth it and I can’t wait for my next appointment with them. We discussed potentially getting Invisalign cause I failed to wear my retainers after having my braces many many years ago.

Liora M. from San Francisco, CA (Source: Yelp)

★★★★★

Dr. Rexan has been my dentist for almost a decade, and I’m so grateful for it! She
is incredibly gentle and caring, and really listens to her patients. I am really sensitive to dental work and have a lot of anxiety about getting anything done, so having a dentist i can trust means a lot to me. She definitely takes the time to make sure that you are properly numb and comfortable before starting any work – something I have not experienced at other practices. The rest of the staff is also awesome! The office is a calm place, and I’ve always had excellent experiences dealing with billings, scheduling, etc. I highly recommend the practice!.

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

★★★★★

I live by Yelp reviews but never took the time to write my own. But I feel obliged to share my experience with this dental clinic. My very first contact with Samantha (office personnel) to schedule my initial appointment went so seamless. Samantha was so patient over the phone and I had to place her on hold about 5 different times. Even when I came in for my appointment she was so friendly and professional. Dr Rexan was great! She explained the procedure to me in detail before and during, which gave me a sense of comfort. I will definitely continue coming to this dental office for all of my dental needs.

Anitha G. from Oakland, CA (Source: Yelp)

★★★★★

Dr. Rexan and her staff are truly amazing!!! I was visiting SF from out of town and had a horrible tooth ache the day I arrived. My Dad was a dentist so I a pretty high level/ standard when it comes to the care of my teeth and who I choose to go to 🙂  I searched for a dental office in the area and was impressed by the reviews so I called. Dr. Rexan was so nice and was flexible enough to see me during her lunch hour. I got a filling and I left pain free (thank goodness). Dr. Rexan was so attentive and  professional– along with the rest of her staff. If I lived in SF, Dr. Rexan would definitely be my dentist.

Emma C. from Oakland, CA (Source: Yelp)

It’s been almost 3 years that I last visited Dr. Rexan’s office. My insurance plan was changed over to Delta Care HMO. Now, I’m with Delta Dental Plan I’m so excited I’m with Dr. Rexan’s office again. Dr. Rexan is an excellent dentist the best that I know of. She’s very professional, efficient,  friendly, thorough, detail, caring and self explanatory . Dr. Rexan has always put her patient first and she listens to her patients. Also, I really enjoy talking with her staff and they’re so polite and friendly  especially Gina and Ruth, the hygienist. I’m looking forward towards my next visit . I wish I could give Dr. Rexan’s office a  millions stars. Thanks Dr. Rexan and your staff  for all of great years of service you provided for me. Sincerely, Emma Crawley.

I was looking for a new dentist because I wanted a second opinion and I was unhappy with my last dentist. I did research on yelp and Dr. Rexan had good reviews. I called to make an appointment and they were able to work around my work schedule. They are open on Fridays! My last dentist wasn’t. Dr. Rexan gave me a thorough exam and answered all my questions. She showed me my x-rays and informed me I have a few teeth I have to watch. I greatly appreciate her being conservative because my last dentist said I had 3 cavities and had to pay $300. Donna cleaned my teeth and I got free whitening! Her staff is awesome. I scheduled my next appointment at her Union Square office since I work in the Financial District and can see her on my lunch break. 5 stars!

Carol D. from Pacifica, CA (Source: Yelp)

★★★★★

Dr. Marianna Rexan is the best dentist I have ever experienced.  She is a genius and a perfectionist, and with dental work, perfectionism is absolutely appreciated.  I am overjoyed with the work she did on my teeth.    Due to an unfortunate accident I needed a crown put on one of my front teeth and Dr. Rexan did such an excellent job that no one can tell the difference.  I can smile again with confidence.  I cannot recommend her highly enough–she is brilliant at her work and also has the sweetest personality.  My teeth have never looked this good before.   Thank you Dr. Rexan, YOU ARE THE BEST!!!!!!!!!!

I have been a patient at Union Fillmore Dental for 5 years now. And I love it!!! The place is clean and the office manager, Samantha, is sweet as always! Dr. Rexan and the hygenist, Ruth, really knows their stuff when it comes to teeth, and they definitely keep me smiling:D. Usually I would bring my daughter to my appointments and she would be shy and uncomfortable. But at the dental office, my daughter feels the warm welcoming everytime. Feeling very well secured, she became a patient too!! And the best part is, knowing that my teeth are extremely sensitive, Dr. Rexan and Ruth are very soft on my teeth when being attended to. Its definitely a good thing when you know your chompers are feeling good, while looking even better. Thx Dr.Rexan and the Union Fillmore Dental Team!!!

My family and I recently relocated to the area and had to find a new location for our dental needs. Its always difficult choosing a new place and I was hesitant and very indecisive. A coworker mentioned Union Fillmore Dental and I began my research on the location, doctors, employees, atmosphere, etc. Being new to the area it can be hard just going based off reviews, but the reviews were great and after much deliberation with my husband we decided to give it a shot. I was relieved to find that this place was everything everyone said it would be. The staff is very friendly and professional and Dr. Rexan was knowledgeable and welcoming. I’m so happy our search was over and we found a great dental practice to come to regularly.

I have found my “forever dentist” Dr. Rexan is so kind, gentle and thoughtful and her whole staff is wonderful! I graduated today with a new smile after more than a year of braces overseen by Dr. Rexan, thank you so much!! Many Hugs, Linda Devine.

Dr. Rexan and her staff are wonderful, incredibly professional, and paid particular attention to my safety and comfort during my first visit back since COVID. They’ve clearly made meaningful investments around the office in safety and purification equipment, and that level of care is also evident in Dr. Rexan’s patient care. And she’s just a cool person… Highly recommended!

I love that this place is run by an all women staff. Mariana is a super skilled dentist. Been going to her for 20 years. All of my work has lasted and I have had many fillings replaced, bridgework and root canals. She is always sweet and friendly too. If you have sensitive teeth, Ruth is the one to do your cleaning. If you have issues with certain teeth, let her know! She is conscientious and will write down whatever teeth are sensitive and use a topical paste to numb them whenever you come in for a cleaning. You can almost fall asleep while she thoroughly scrapes away your plaque. It’s a relief to know she’s there for me. I used to hate going to the dentist. I thought I was going to have a heart attack every time I sat in that chair with my bib on! While it’s still not my favorite thing to do, I don’t have anxiety anymore and I am truly happy to see Ruth and Mariana. They feel like family to me and they make my dental experience innocuous and pain free.

I don’t like going to the denitist but I don’t mind going to see Dr Rexan & her staff.  They are very pleasant & helpful and always nice & professional too.  Dr Rexan is a very skilled dentist and has performed several procedures on me such as cavity fillings, crown replacement & tooth bonding with no complications and virtually pain free.  She has improved my smile with the tooth bonding & I am very happy with the results.  The office is easy to get to & I can always find parking in the neighborhood within a few blocks.  I know that oral health is important to overall health & I feel lucky to have found such a great dental practice that has my complete confidence!

BEST EXPERIENCE POSSIBLE!! Dr. Marianna Rexan is not only one of the nicest people I’ve met, she over all ROCKS! The staff was unbelievably friendly. In fact, the receptionists were so nice, one of them (Nancy) gave me recommendations to places to go to here in San Francisco since I just moved to town. Good service is so hard to find these days and walking into Dr. Marianna Rexan’s office was a breath of fresh air and a reminder that there are people that care and quality about the services they provide. Thank you guy’s for making my experience more than formidable.

I have lived in the Bay Area for over 3 years now, and since moving from NYC had to find all new doctors as one does when they move. General practitioner, dentist, gynecologist, dermatologist, etc. Dr. Rexan is the only doctor in the past few years that I instantly gravitated towards and knew I would stick with. She’s very gentle, communicates every step of every process and really, really makes her patients feel comfortable. Also, I never ever feel rushed. She always makes you feel like you’re the only patient in the room and she really cares about the work she’s doing. Her dental assistant and receptionist (Samantha) are equally as great!!

If you are looking for a great service, that is the place.  it was recommended to me by a co-worker, when I started to feel a toothache. Didn’t have much expectations, just wanted to get it fixed.  Everything was very easy:got on the website, scheduled my appointment online, filled paperwork at home, emailed it back.  Was wormly greeted by the receptionist and met the doctor.  Dr. Rexan was very nice, attentive and thorough.  It turned out to be just a gum infection, also i got the full check-up: gums, teeth, jaw-joint, oral cancer test.  During this one hour exam I learned more about my mouth, than I ever new. They use latest equipment : intra-oral camera, laser gum treatment and a different one for cavities detection.  A bit pleasantly surprising that with all the new dental stuff, office is located in an Victorian building in the center of the Marina.
And an the anesthesia shot, I didn’t feel it at all.  I was told doctor is using a special pediatric technique..

I has been a longtime patient of Dr Rexan and Ruth. Sometimes we forget about how good thing are good, because they just there. Today i just got a reminder about it: scheduling, reminders, atmosphere, attention, gentlest teeth cleaning, thoughtful instruction and suggestions on improving hygiene techniques, no-hassle insurance dealing. All is done just right. Thank you.

I have now had two appointments with Dr. Rexan and the staff at Union Fillmore Dental, the first a regular ol’ checkup and then the biggie, a trifecta of fillings all on the same day. While three fillings might not be how I’d like to spend every Friday afternoon, this was about as painless – literally – as it could be. The staff applying the tooth numbing stuff (I assume that’s the technical term) was very patient with me as I waited to make sure everything was as numb as could be before the action began. Dr. Rexan was very thorough in her explanations of what was about to happen, how long each part would take, and what I was going to feel (basically, I wouldn’t feel a darn thing). Dr. Rexan also called that Friday night, several hours after the fillings, to check-up on me, which was nice. Oh, and while you’re in the dentist chair there is some great Marina people watching from the Union/Fillmore intersection!

I was about to travel overseas when a toothache hit. They won’t let me change my travel plans at work, but I was able to get an appointment at Union Fillmore Dental within hours from the time I called. The appointment itself went great! First, they really take time and effort to make sure you feel no pain and is absolutely comfortable during the treatment. All people are different and I have sensitivities to certain medications, Dr. Rexan took plenty of time to find anesthetics that worked great for me. She took plenty of time to investigate the cause of my problem and explained things to me in a “normal” plain terms that I can understand.  All of them worked long hours that day because of my drop-in emergency and Dr. Rexan made sure that everything was done and complete, before I left. I am happy to found this dental office where people know what they are doing and have great attitude, both compassionate and professional. Will definitely go there again.

I hate going to the dentist. I hate it so much that I have not been in over three years. Finally I knew I needed to schedule an appointment and my friend recommend Dr. Rexan. She made me feel extremely welcomed and so comfortable I didn’t even feel like I was at the dentist, it felt as if I was visiting a friend. The best part of the trip though was meeting Samantha. She greeted me right away and I must say she is drop dead gorgeous. I didn’t want to leave her presence! (I hope Samantha is single) Anyway I am going to schedule a check up soon and I highly recommend this dental office to everyone!!

After I moved to San Francisco I ignored my teeth for over a year because I didn’t have a dentist in the area. One morning I woke up with a horrible pain. I called my friends and one of them recommended Dr. Rexan. I called the office to make an appointment and I was seen two hours later. Dr. Rexan quickly diagnosed the problem and started treatment. She went over different options with me and discussed not only dental but also financial implications of every option. I had a root canal done that went well. Since the first appointment I had a few more to complete the treatment. Dr. Rexan is very approachable. I am very satisfied with my treatment. Now I have “my dentist” in San Francisco. Next time I won’t wait for pain to be seen.

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

★★★★★

Dr. Rexan and her team made me feel so welcomed from scheduling to walking in and getting seen right away. I called in that day due to horrible pain on the right side of my mouth and Samantha (who is absolutely awesome) listened to me and offered to get me in the same day. When I got there Dr. Rexan brought me to her chair and took X-Rays, she was very gentle and informative of what she was looking for. Of course she found the source of my pain and prescribed me antibiotics. The office is clean and has a beautiful view of SF while sitting in her chair. Overall, I give them 5 stars for working together and trying their best to make make sure all their patients leave satisfied. Yes, I am coming back again for my cleaning in 6 months.

Dr. Rexan and her staff are very nice and professional. I have been going to her office for the last 3 years. I am very pleased and satisfied with the care and service I get every single time. I have never waited more than 10 mins in the wait room to start getting awesome care. If you need a caring dentist and a professional service Union Fillmore dentist is a place to go. My mouth have never felt healthier. Thank you Dr Rexan and the rest of the staff for making this experience pleasant.

My face is throbbing. I want it to fall off like the last apple on a tree so it will stop. Unfortunately, they tell me I need my head or else the rest of me won’t function. I haven’t even gone to Dr Rexan yet, but I will say this (and update my review after my appointment with her next week) that she is kind and attentive over the phone. And that says a lot about a person!! Especially a dentist. I have been battling a toothache for days and after making an appointment for next week with her, I couldn’t take it anymore. So I called her office, and discovered they aren’t open on Fridays! AHHHHHHH. (minus 1 star). BUT, I called her emergency cell line and she picked up right away and listened to me as I whimpered about my pain to her. She offered right away to see me for an exam tomorrow to assess what was going on in the bacterial pool that is a human’s mouth. (+ 1 star). So, my brief, and current review is for the fact that Dr.Rexan wasn’t annoyed I called her early on her day off. Instead, she treated me like I was an old patient and wanted to make sure I wasn’t going to expire between tomorrow and my appointment next week. 5 stars for that.

Dr. Rexan and her staff are truly kind and wonderful!  I’ve been going to her now for over a year and every visit has been very positive. I moved into the city about a year and a half ago and looked on Yelp and found her. She just worked on two veneers for me and I couldn’t be happier! They look like my real teeth and I am soo happy overall! Dr. Rexan totally relaxes you when she gives you a shot of novicane and you can’t even feel the needle…. I hate needles and I have never felt it… She does a great job relaxing you! Her staff (Gina, Mellanie and Lisa are so great!) I highly recommend going to see Dr. Rexan if you have any teeth needs to be looked at!

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

★★★★★

Dr Rexan and her staff are incredible. I found them on Yelp (thanks Yelpers!) and made an appointment after a less than stellar experience with a dentist in SOMA. They’re in my network and in my neighborhood which is great. But what really got me was how sweet her front desk person is and how considerate Dr Rexan is. After a couple fillings and a crown Dr Rexan called me the evening after each procedure to check on me. The personalized experience and homey office is what I want from a a dentist. Thanks Dr Rexan and team!

Ana Carola Vacaflores (Source: Google)

★★★★★

I really like visiting Dr. Rexan. Her whole staff is very polite and kind. The environment itself is pretty calm and Dr. Rexan is the most patient dentist I have ever had. She takes her time to explain everything she sees and is planning to do. I was very comfortable listening to her explanations and understanding in detail what we were going to do. She also made sure I was always at ease and feeling no pain or discomfort. I totally recommend her for anybody, especially if you are anxious about dentists!

Elis N. from Cupertino, CA (Source: Yelp)

★★★★★

I have had a traumatizing, anxiety inducing fear of all dental institutions since I was a child. It got so bad I would cry as soon as I walked into the office. This dental office turned my expected experience 180 degrees. Dr. Rexan assured me that nothing would be done without my knowledge and approval, the tone, demeanor, and atmosphere of the usually foreboding situation put me at ease. I would 150% recommend this dental office and Dr. Rexan to anyone with even the slightest fear of getting dental work done!!
