Dr Lisa Siu was wonderful! She made what could have been a nerve-wracking procedure, very comfortable and easy. She humored all of my curious questions and was extremely dedicated to make sure the end result was superbly finished! If I ever need another Endo procedure, I'll definitely ask for her again. And, I'd be remiss not to mention the entire staff was incredibly kind and helpful :)

This was as straightforward and smooth a root canal procedure as I could wish for. I felt in very good hands with Dr. Lisa Siu and her assistants and recommend her and her office strongly.

Dr O'Callahan is brilliant. Her ability to explain the problem and the options on how to address the problem are much appreciated. Her manner puts you at ease. Fabulous assistant too!

Dr. Priya O'Callaghan must be one of the best endospecialists in the business. I needed the most complex root canal I have ever had, plus checking for decay under the crown of the tooth. Normally this would have taken at least two appointments. She did it in one. I will be sure that, if I ever need another root canal, she will be the endospecialist who does it.

I needed root canal therapy for a tooth and Dr. Siu and the team were meticulous, and I felt very comfortable. The consultation and the procedure itself went very smooth, and I felt no pain during the recovery!

I was impressed with Dr O'Callaghan in that I was referred by my dentist for a root canal and, after her assessment, she determined it was not warranted at this time, after doing an exam. I have had root canals in the past by other dentists, without a pre-exam first and I very much sppreciated her analysis.

This dentist has questionable covid protocols. The people working the front desk had on only surgical masks, nothing that filtered the air they were breathing out, or in. The doctors and assistants wore N-95 masks (much better) but were not wearing eye protection, face shields, or any of the other PPE I am accustomed to seeing my own dentists wear. I suspect this office hasn't had any problems with Covid, but I didn't feel safe there. They did at least check patient temperatures and had me wash my hands before sitting in the chair. I also suspect I may have had a root canal that wasn't necessary. I went in with tooth pain in a tooth with a root canal. It felt like the tooth was too tall, and it was taking more stress than those around it. After getting a new root canal, I had the same pain as before. Then, the dentist shortened the tooth, and now the pain is gone. I wish they would have tried that before I got the root canal.

I'd rather have a root canal with Priya O'Callaghan than a cleaning with just about any hygienist - it was that easy. First, Dr. O'Callaghan is smart, confident, witty, and human - I was immediately at ease in her care. Then, her office is efficient, friendly, and accommodating - they went above and beyond to make the appointments, paperwork, etc. easy. And her dental assistant Kenneth is a critical part of the excellent care you get during the procedure - he made sure I was informed, comforted, and understood. The procedure itself was quick and, frankly, painless for the most part. I can't say enough good things about Dr. O'Callaghan and her practice.

Endospecialists, and Dr. O'Callaghan specifically, provided me with exceptional care and ultimately helped to save my tooth. I went to Dr. O'Callaghan with what was an enormous infection and abscess under my bottom molar. Likely due to a previous root canal under the adjacent molar, I wasn't actually in much pain. However, I had noticed significant changes in my bite and that my back molar felt loose, the tooth was literally coming out of its socket. She carefully walked me through my treatment options, which included just having the tooth extracted or trying a root canal procedure to see if that would help. She clearly explained that I had some fairly significant bone loss, and that the root canal may not work but there was a good chance it could help clear up the infection and if we were careful, it could solve the problem. Together we charted out a course of treatment for a root canal hoping to avoid extraction and possible implant, which would have been even more costly over time. The root canal treatment was amazing. Post procedure I didn't even experience much pain. She and her team scheduled a series of follow-ups so we could cautiously evaluate the situation post-procedure. I'm excited to report that not only is the infection gone, but my bone has regrown and we will be able to save the tooth. From what I understand, years ago they likely would have just immediately opted for extraction, but Dr. O'Callaghan and endospecialists, who also happen to have some pretty killer imaging and root canal tech, were able to save the day.

Simply the best... With your mouth wide open and all your nerves exposed, it's super important to feel like you're in good hands, and Dr. O'Callaghan is the Michael Jordan of Endodontics.

A recent X-ray showed I had reabsorption in one of my molars, which totally sucks (get those X-rays!) and I was referred to Dr. O'Callaghan's office for a root canal. This was my first root canal, and she was incredible: communicative, clear, thoughtful, and most importantly super good. Apparently with reabsorption you might end up losing the tooth, and I was right on the edge of that. She did some delicate magic and I'm able to keep my tooth, AND it didn't hurt. TLDR Her hands are magic and I'll never go anywhere else.

I was in such extreme pain. I saw my general dentist and they referred me here. They were able to take me in right away. I'm such a scared patient usually but they made me feel very comfortable. Staff is extremely nice and helpful. Dr. Fujimara is very kind and knowledgeable. So glad my dentist referred me here!

Very caring and nurturing. If it weren't for the terrible pain I brought in with me, I'd say a great experience. Thank you so much for coming in early to accommodate me Dr. O'Callaghan!!

Dr. Priya O'Callaghan is a class act! Dr. O'Callaghan and her team went above and beyond to accommodate my dental anxiety. They all were the best kind of fantastic. All her equipment looks brand new and state of the art, I decided to have her use the gentlewave and just WOW! I had zero pain after the anesthesia wore off. I will never have another root canal without gentlewave. I went into her office feeling like my tooth and head would explode and left completely relieved of pain. It was as if she just flipped off the pain like flipping off a light switch. I sure hope that I do not need another root canal anytime soon. But if I do, I will return to Dr. O'Callaghan's office and insist on the gentlewave!! Thank you Dr. O'Callaghan and team!!
