So disappointed in our family's experience here. This was our second visit for our child. Our first…read morevisit was complimentary due to a promotion. At that time, I went over our insurance information in detail with the front desk staff. I was told that although our insurance was out of network, it would fully cover cleanings and basic visits. We returned on 2/11/26 for our 16-month-old's appointment. The staff brought us back, asked a few questions, and the dentist examined and counted my child's teeth. That was the entirety of the visit, which was fine and expected for their age. However, when we were leaving, the front desk charged my husband $97. I was surprised by the cost given the brief nature of the visit and confused about why our insurance hadn't covered it. Since we hadn't been in since August 2025, I assumed perhaps our coverage had changed in the new year. Something didn't sit right, so I called the office the next day. I was told they had not run our insurance and had charged us directly instead. They were aware of the mistake. While I understand mistakes happen, what concerns me most is that the office was aware of the error but did not reverse the charge, notify us, or apologize. I can't help but wonder whether we would have ever received a refund had I not called. Mistakes happen in any business, but how they are handled matters. Unfortunately, this experience left us feeling uneasy about the office's transparency and communication. I have requested that any future appointments be canceled, as we no longer feel our values align.

If I could give zero stars I would. This is the first negative review I've ever written as I really…read moredo like to give people grace and not blast them on yelp but this has to be said. My 6 year old son was seen at his regular dentist on July 21st and needed a tooth extracted. The dentist said it was urgent so she got me in the next day. They did the nitrous oxide but my son still went into a panic and was screaming so we could not get it done. We were referred to PDI (Pediatric Dental Institute) so that they could do the procedure under general anesthesia. But because we have Kaiser medi-cal we had to be seen by a dentist/oral surgeon that was in the Kaiser network. Enter in Dr. Van Tassel. 3 weeks later and after 3 canceled appointments and my son being in severe pain I called into Kaiser to get authorization to go out of network. I talked to a very nice and understanding Kaiser doctor who understood my concerns and spent hours trying to get authorization for me. Finally, he said I would be able to go to PDI and Kaiser would release my son so we could get the dental surgery done. PDI said if they received the formal authorization quickly we would possibly be able to do dental surgery the very next day. But then I get a call back from the Kaiser doctor who said that Dr. Van Tassel needs to release my son and she would not do it because she felt like she could get it done in a timely manner and would be back in the office next week so we could do an ASSESSMENT...not even the surgery. She said that it was not an urgent matter. Kaiser only gives two dates a month to do oral surgery so we would then have to wait for the opening. The Kaiser doctor explained to Dr. Van Tassel that my son was in a lot of pain and she replied that we could go back to our normal dentist to get pain management. Are you serious?!? How cold and heartless can you be to not release a 6 year who is in PAIN so that you can get paid to do the procedure after THREE weeks and THREE canceled appointments?!? This is beyond unacceptable. I will be figuring it out and paying OUT OF POCKET to get the surgery done at PDI because there is no way I would trust my son to be seen by this woman.

MY experience at this office started out fine, but I've since had two very disappointing…read moreexperiences and have left for another dentist. I've always taken good care of my teeth but due to nighttime grinding, eventually had wear a mouth guard. Apparently I had a few teeth with cracks by that time and Dr. Mangrum told me I would need crowns so over the course of two years I had three crowns put on. One of them fell off within a few weeks of being put on. I returned to the office and they re-cemented it. A few months later it fell off again. At that point they told me I didn't have enough tooth length to hold onto the crown (I felt this should have been known from the beginning) and I needed a new procedure where they cut away some gum to lengthen the tooth. They made a new crown and when they cemented it in, they exerted the most pressure I have ever felt in my mouth. Two years later (and crowns typically last a lot longer than that) I developed a toothache around that crown, the first toothache I have ever had. I knew something was going on (I suspected an infection) so I made an appointment and went in. The dentist recommended that I see the endodontist (root canal guy) in their office so I went in again to see him. He didn't take a CT scan (common procedure I came to find out), and after tapping on my tooth and blowing air on it he pronounced me fine and told me to just keep an eye on it. A day or two later I was in so much pain, I knew it was infected and called the office to get a prescription for an antibiotic. I didn't want to return to this office since they had missed the infection so I found another dentist who could see me immediately. He took a CT scan and saw a raging infection. Referred me to an endodontist. She also took a CT scan and told me my tooth was unsalvageable, big infection, and needed to be extracted. I began this process and ended up with an implant. At this point I thought about writing an honest review of my experience but decided to leave it alone. My second bad experience- a month ago I was eating and felt something crunchy in my mouth. It was part of another crown Dr. Mangrum had done that just slid off the tooth. It was 2 1/2 years old so insurance won't cover a replacement. My current dentist saw me immediately and made me a new crown. I called Dr. Mangrum's office to talk about being reimbursed for this since it was a relatively short time since it been put on. I explained that I didn't want to return to her office to have it done because I had no confidence at this point in the work being done since having two fails. They denied my request for reimbursement, even partial, citing that they would have looked at it and might have decided to replace it at not cost to me, even though I fully explained why I wouldn't return to their office. Once trust and confidence are gone, it's hard to put yourself in that situation again. I almost never write a bad review. I don't know f I ever have, to be honest, but I felt so let down by this experience that I thought it was time.

I was a patient of Ms. Smida when she had her practice in Petaluma at 4th & B. She was sketchy in…read morethe extreme. She did a "root planing" that took all of 20 minutes, did NOT plane at all - just roamed around in my mouth with a pick but charged my insurer for the planing. Then she did a root canal, she made the crown out of some extruded plastic goo that was hardened using UV light, looked pretty cheesey when she did it and sure enough it failed the next day. Was seeing her for 2 years and I gave some serious thought to filing complaints at the time but did not. It utterly destroyed my trust in dentists, I have literally not seen one since and that has been 13 years ago and have broken/missing teeth. This woman is a crook.

This is one of the worst dental offices I've been to. I went to Dr. Smida regarding wisdom teeth…read moreremoval. Despite the fact that my dentist sent all of my current x-rays, they took more and then did a cone beam x-ray. All Dr. Smida had to say was not to remove the wisdom teeth. She sent me a copy of the cone beam report and it stated I had a tooth with pulp resorption which needed to be removed. I called the office to find out if she would take it out and she no. When I called back again to ask how urgent this matter was, I was told the doctor was too busy and to book another appointment to discuss it. I also did an oligoscan which I highly recommend but not at this office. I had some serious irregularities which Dr. Smida said she would have to check with her tutor for a treatment plan. When I spoke to her on the phone, her recommendation was to take epson salt baths. I've spent months researching what I need to do and have found her response to be pathetic. They won't even print the report for you; they email it. But they only email 2 pages even though there are 3 pages. Since I saw the 3 pages in the office, I told them I want the 3rd page which I did eventually get. This office may do the scan, but they sure don't know how to offer a treatment plan to fix the problems. I spent just over a $1,000 - what a waste of money!

Patient for 20 years ... now they commit fraud. Copay per insurance $5, they decided to "say" (aka…read morelie) that the copay is $25. When challenged they say - "well, we add a $20 fee on top of the copay". Not kidding! They then invoice insurance that $20 via bogus billing code, knowing it will be rejected but to sorta cover the fraud. Multiple layers of fraud. When challenged, they say we will cancel your appointment if you do not pay the fraudulent copay upfront. Anyway, fraud reported - got my money back and moved on!!! Beware, check your insurance because they will lie and feel totally justified in that. Really too bad, Dr Husein is great - perhaps just really, really horrible back-office team that is willing to commit fraud. He needs to fire them. Hard to move on after 20 years ... but they made it clear they cared more about stealing $20 from me per cleaning than keeping me as a patient.
