I know my teeth are in the best care with Dr. Mostashiri
Amazing. Professional, honest, and very friendly
She and her staff did a great job for my and my kids.
Always a pleasure to be there for any dental procedures. Very professional and courteous.
I appreciated my entire experience with Dr. Mostashiri and her staff. They were warm and efficient and prepared. I loved how Dr. Mostashiri explained things to be and patient took the time to answer. She also had a warmth and openess about her. Unlike any other dentist I have been to, she also took the time to ask me lifestyle questions and encouraged me to look after other non- dental aspects of my health. I'm impressed and I would highly recommend.
I love these people. The Dr and her staff have been great. I'm so happy I've found her.
I went in for my first dental visit in years and Dr. Mostashiri explained what she was checking for and why, and why she recommended what she did. When she found I needed a filling for a cavity they made it easy to get it seen to quickly and that appointment also went well. Would recommend.
The doctor and her entire staff were kind, friendly and highly professional.
Filling repaired in less than an hour. Little or no pain.
Very professional, warm and extremely knowledgeable doctor and team-- in an environment that is soothing and has the latest technology.

She is the best I've been going to her for over 15 years. I don't feel the shots and she does great work a perfectionist.
The entire team is very friendly, professional and provided excellent service. I had several procedures that had to be done from bridges, fillings and deep cleaning. All procedures were performed well. They worked around my schedule and I appreciate their sense of caring and assistance. I highly recommend Dr. Mostashiri . My entire family started to go to this office and they are child friendly.
Excellent, caring and thorough dental care. Dr. Sepi follows my history from one appointment to the next. Nothing falls through the cracks. Great staff in her practice.
Detail oriented, Nice professional service, had a good experience. Would certainly recommend people.
Overall excellent dentist with a flair for precision and patient interaction.
I looked up for a new PPO dentist on my insurance website and Dr. Mostashiri was the closest to my house. I called and requested an immediate appointment due to the my pain I had been enduring. I was scheduled for the next day and seen right on time. A complete assessment was done. Dr. Mostashiri is very patient and great listener. She explained the prognosis of my teeth in detail and made an action plan on how to address all of the them. The office manager, Sahar, was very cordial and professional and the dental hygienist was extremely capable. I have since scheduled two of my children to see her and have referred her to my entire family and relatives. I highly recommend Dr. Mostashiri.
Very friendly, attention to detail, answered all questions.
she is the best. I have had my best dental visit ever. the staff is so kind and friendly and I would say they are doing their job great. special thanks for Sahar and her assistant.
Dr. Mostashiri is a great dentist. She is thorough and gentle. She is good on tracking follow-up issues and monitors related health issues. I would highly recommend her and her practice to anyone looking for a new dentist.
We just moved to the bay area and have been searching through all of the doctors and dentists in the area to make up our medical team. I am so glad that we found Dr. Mostashiri's office. 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 began by reviewing my medical history with me while getting to know me as more than another set of teeth. Her bedside manner is the best I've ever experienced. 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. She referred out for orthodontic and surgical consultation to further my oral health. Honestly, I am so relieved to find a dental office that is so welcoming and warm. I always seek doctors who run their own office, not those in giant multi-clinics. This is one of the best!
Staff was very friendly and welcoming. The receptionist was very sweet. Dr. Mostashiri was amazing. I hate going to the dentist but she made it very easy for me. She walked through everything with me so I was comfortable. I had a great experience!
She was great and her staff too. It was a very nice experience. I felt in good and expert hands. Her work was great on my filing! She explains procedures, risks, shows you the work. Excellent!
