I've been a patient of Dr. Mostashiri for over 16 years, and now my daughter sees her too! She is a truly compassionate dentist who explains treatment options with real passion and a genuine human touch. When I recently started experiencing a brief period of panic attacks, her empathy and patience made all the difference. Plus, she has an incredibly "light hand"--her procedures are so gentle. I highly recommend her as an excellent dentist with a kind heart. read more

Dr. Sepideh Mostashiri is a great dentist. She provides great dental plan that best suits my dental situation. I feel so thankful when she addressed my questions even during holiday time. And she is such an elegant person~! read more

Great dentist! Saw me with very little notice and helped me deal with a temporary filling and referred me to a root canal specialist who then did a good job as well. read more

The staff are very professional and efficient. Bedside manners are incomparably the best. Almost 10 yrs ago when I relocated - 30 min away. The office was gracious enough when I told them I'm switching to a different dentist. I had 2 different dentists since then. I made a decision to come back regardless of the longer travel time. Did my first visit back today. I am convinced it's a very good decision. read more

I've been seeing Dr. Mostashiri for many years and have always been very happy with the excellent services received (be it cleaning, filling, or fixing an incompatible European model implant). Dr. Mostashiri meets the highest professional standards you would expect from a great dentist. While at the same time her kind and compassionate style complements that. Sahar at the front desk is highly professional, accommodating and would work with you to find the best possible time slot for an appointment whether you schedule a new or move an existing one no matter how busy Dr. Mostashiri's schedule is. Sahar's welcoming and friendly appearance is a great start for your appointment experience. The entire team is great and it's a pleasure to be their patient. I highly recommend Dr. Mostashiri's office. read more

I was one of Dr Mostashiri's first patients when she took over the practice a decade and a half or so ago from Dr Park, who was a hard act to follow. Dr Mostashiri is a first rate dentist and highly skilled artisan, and strange as this may sound, it is a pleasure to have her work on my teeth. What sets her apart from any other dentist I've dealt with is the rapport we've developed during our many sessions. My dental work is a delicate collaboration between her skilled hand, eye and knowledge, and the cognition of my tongue and jaws. Dr Mostashiri is very receptive to my input about how I experience my bite, or pain, or anything else I might consider important, so that I never feel that she is working on me, but that we're doing this together. For the first time in over 40 years, I now have a complete set of teeth. After decades of stop-gap partial dentures, and then a bicycle crash that knocked out a whole line of front teeth, it was time for implants. But first, my remaining natural teeth had become so worn down that my jaw had essentially collapsed and was locking up. Over the last several years, Dr Mostashiri replaced crowns, and added material to my natural teeth to completely restructure my bite - the way my teeth come together - and then installed implant crowns to replace the missing teeth. It has been a long, tedious process, but it has also been exciting and fascinating, and I've come to know my mouth in ways I would never have imagined! I'm lucky. I think I have the best dentist in the world. read more

Always great experience. Great staff, very clean. Doctor always takes time to answer questions and makes good recommendations. read more

I have been a long time patient of Dr. Mostashiri's. I've been very happy with her care. She takes the time to listen to my concerns and addresses each one without ever making me feel rushed. On more than one occasion, she's accommodated me with emergency appointments. She genuinely cares about her patients' dental hygiene without being preachy about it. Dr. Mostashiri is very personable and has excellent bedside manners. Her front office staff, Sahar, is also very kind and easy to work with. read more

Dr. Mostashiri is amazing and her entire staff are all so friendly and amazing! She is very gentle, you can't feel a thing!

Totally Disappointed... Today I took appointment for my wife for tooth extraction and filling. 1) I called and got it confirmed the tooth extraction is done by Dr. Mostashiri. Even lady on the phone confirmed which tooth we want to get extracted. 2) Website also mentioned the tooth extraction is done. On reaching there it was found that Dr. Mostashiri did not do tooth extraction and they wanted to refer to some other dentistry. It was really disappointing and unprofessional. It wasted our time. We have new born twin babies at home and having very limited time and Covid is another problem these days. read more

I have been with Dr. Mostashiri for years. Dr. Mostashiri is an AMAZING dentist. Her diagnosis is right on and her work on my teeth is impeccable. I drive 2.5 hours to go see her because no other dentist (and I have had many) is as gentle, and capable as she is. Her staff is professional and wonderfully kind and caring and very knowledgeable. I'm always greeted with a warm smile and always feel so relaxed and comfortable. I highly recommend her! read more

What a beautiful office . . . from the soothing environment, to the people. I was greeted by Sahar a warm caring and highly skilled dental professional. Sahar is lovely, helpful and welcoming with her warm and knowledgeable conversation. The dental assistant is also amazing. She has a very sweet personality, a beautiful smile and was very thorough and efficient when she was taking my xrays. She was very comfortable with the dental equipment, the computer and most of all was very kind. Dr. Mostashiri is wonderful, simply wonderful. She began her introduction with a warm smile, and a thorough review of my medical history and my smile. The dentist asked questions in a way that was helpful for me to understand. Her interaction was caring. The dentist was gentle in my mouth and took the time to provide a complete dental exam that ended with a thoughtful conversation of priority work. She shared with me the things that could wait, and was also very clear in her communication with me what was important to address. I like that she uses dental magnifying loops, has a deep knowledge of cosmetic and general dentistry training and has a grounded personality, with a soothing and beautiful energy about her. I fell in love with her and her entire team. This truly is my new dental home. Thank you Dr. Mostashiri. I am happy to have found them and to know that I have a dental home that I can feel comfortable to return to. My new dental office, I just could not wait another moment to go online to share with everyone just how wonderful you all are. I look forward to referring friends and family to you. I hope that you never move from our neighborhood- You are all so wonderful at what you do. I am super lucky to find you! Thank you so much. See you on the 23rd! read more

I moved down to San Jose from San Francisco and was referred to Dr. Mostashiri by a friend. I made an appointment for an exam and was seen promptly upon arrival. The office was hospitable and the front desk staff was exceedingly pleasant and efficient. The hygienist did a great job and was very nice as well. Dr. Mostashiri was fantastic. She did a thorough exam and took time to answer my myriad questions and go over all my treatment options at length. For one issue she made a referral to an endodontist and stated emphatically that I musn't wait. But I did. The following Friday she really went way above and beyond to help me out in a real jam. I had a serious problem with a tooth and wasn't scheduled to see the endodontist until the following day; I was in extreme pain. Her office is closed on Fridays, but I got in touch with her through her emergency number, and she came in and met me at her office in order to give me a prescription to see me through to following day's endodontist appointment. She's a wonderful, caring dentist and I couldn't recommend her more highly or with more confidence. read more

I can honestly say that Dr. Mostashiri is one of the best dentists that I have ever experienced! My family and I have been seeing her since 2009 when she moved into her Sunnyvale office and we have been referring patients there ever since!!! She has such a calm demeanor that puts anyone at ease and her staff is amazing as well. They all work as a team to keep things running smoothly and Dr. Mostashiri always explains her treatment plans with her computerized digital x-rays and photos! I have been very pleased with her services! read more

Her reception staff and dental assistants are great at what they do. Everyone was so patient and efficient with checking in my insurance, medical history, and transferring my records from my previous dentist. Dr. Mostashiri performed the new patient exam, cleaning, and saw to some other concerns I had all herself. She was so warm and thoughtful, constantly getting to know me and my dental habits better throughout the visit. My cleaning and exam were comprehensive and wonderfully executed. I am so relieved to find a dental office that is so welcoming and high quality. read more

I am being very well cared for by Dr Mostashiri and her staff. They are available when I need them, they go the extra mile. I have been going to that office for over 25 years. Dr Mostashiri is my third dentist there, previous dentists having retired. Laura, the hygienist is outstanding. Good, professional, dependable. read more

Friendly, knowledgeable, accommodating. I'm lucky to have found this office after needing an appointment on short notice. Since then I've come back for additional work. Coming from someone that generally avoids dentists until it's too late, the fact that I keep returning for check ups and getting past neglected work done says a lot. Thankful for Dr. Mostashiri. read more

I always hated dentists. Until I found Dr. Mostashiri. She's amazing. She has the gentlest hand of any dentist I've been to and I sometimes fall asleep! And she's unbelievably thorough. I hadn't been to a dentist for years and my teeth were in horrible shape. With any other dentist I would have had several root canals but she was able to save all of my teeth. I HIGHLY recommend here! read more

Dr. Mostashiri and her team go above and beyond to make your experience enjoyable, educational, and ensure that you get the best care possible. I came to Dr. Mostashiri on the recommendation of a nurse, who sent me her way after I received terrible dental services elsewhere. At the time, I was a student without dental insurance, and Dr. Mostashiri worked with me to make sure that my care was top-notch and affordable. In a business where the patient often does not understand the intricacies of the work that needs to be done, I have never once felt confused, pressured, or scared about any procedures. The office has a warm and welcoming atmosphere: I never feel rushed, and in fact great enjoy my time catching up with Dr. Mostashiri and everyone else who works in the office. She and her staff genuinely care about each patient, and are helpful and trustworthy. I can't recommend Dr. Mostashiri more highly!!! read more

I have been a client of Dr. Sepi Mostahiri, DDS, for 15 years. She is concerned about her patients and wants to help keep their teeth healthy and provides educational tips to assist all in doing so.

My teeth feel great after each cleaning. I highly recommended Dr. Sepi Mostahiri and she is simply the best. read more

My family and I have been patients of Dr. Mostashiri since 2008. We are so thankful to have such a wonderful dentist! Her office staff is both professional and considerate. We always feel welcome and well-cared for at our appointments. The office itself is up to date with the latest in dental technology. The office is also clean and neat. Dr. Mostashiri takes her time in explaining the treatment plan. She is patient and courteous. She is honest and fair. And, very importantly, her work is impeccable. I have had crowns placed by other dentists that never fit quite right or failed after just a few years. The crowns fitted by Dr. Mostashiri felt great from the beginning, and 6 years later continue to perform superbly. She also uses an excellent network of specialists, if needed. Dr. Mostashiri is also there when you need her. Recently, our neighbor had a dental emergency. Dr. Mostashiri got her right in (coming into the office on her day off), and took care of the problem. We've referred many friends to her office, and they've all been extremely satisfied with her care. Dr. Mostashiri also expresses appreciation for the referrals. We are so happy to have such a wonderful dentist and highly recommend her office and staff. You won't be disappointed! read more
