    I was originally referred by my dentist to a different Endodontist nearby however this particular…read moreoffice unfortunately didn't accept my dental insurance, the doctor was also away for vacation and the next earliest available time for consultation appt (no treatment) wasn't until May 17th despite mentioning I was in pain (toothache). After talking to my husband for other options, he remembered his own experience he had with Tri-Valley Endodontics office here in Pleasanton, he had nothing, but positive feedbacks and suggested I get a referral for this particular Endodontist office from our regular dentist and so here I am. Just like my husband, I have nothing, but positive outcome/feedback as well. In my case, .. about 20 yrs ago, the questioned tooth went through a root canal treatment + crown. From then to now, bacteria managed to slip through which caused painful toothache (sharp pain followed by throbbing) when I ate soup (broth). I right away called Tri-Valley Endodontics office after seeing my regular dentist. Nothing showed up on their X-rays. When tapping on several teeth, the pain always came from the questioned tooth. The front desk scheduled me in for an early appt, which during this phone call I learned Tri-Valley Endodontics does both consultation + treatment on the same day. I was expecting I had to reschedule a separate appt for treatment, but this office does both during your 1st appt. My husband was seen by a different doctor and I was seen by Dr. Kim. Dr. Kim was very thorough by giving me options, she explained everything and any questions I had she answered so patiently. Just in general, every patient case is different so everyone individually will have different outcomes. I also didn't know you can still experience pain even though I had a root canal treatment done many years ago. Even my regular dentist thought it was strange I would feel pain from a tooth I had done a root canal previously. I remember telling Dr. Kim and she mentioned I still have surrounding nerves so when bacteria got into my questioned tooth explains well why I was feeling pain. Before drilling, Dr. Kim also took time to make sure the pain was coming from the questioned tooth and not from a different tooth. X-ray, again, didn't show anything, she tapped my tooth, I felt pain/tender and she also placed cold sensation, but was told she didn't place the cold air on the questioned tooth. I was going to ask a question regarding that, but I didn't. I just knew the pain was coming from the questioned tooth. Dr. Kim basically went into my tooth, drilled a hole, took out the old root filling even though it was perfectly fine, but because bacteria got into my tooth she placed medicine inside the canals followed by a temporarily seal. Due to time conflict on my end I went back to Dr. Kim about 2 weeks later. Enough time to see how well my tooth would heal. My toothache continued to last for 3-4 days after my 1st appt, but as time went by as the medicine kicked in + taking OTC as instructed helped me get rid of the toothache I initially had. It's been 2 days after Dr. Kim went back in, replaced the medicine with new root canal filling + build up + permanently sealing my tooth I've been able to eat just fine. No pain at all. Dr. Kim and her office staff were all friendly, caring, I didn't feel rushed or anything like that. Dr. Kim's assistant took several X-rays (before, during and after). Like I said, "My experience with Tri-Valley Endodontics Pleasanton location was nothing, but positive and this office accepted my dental insurance." Thank You, Dr. Kim and office staff. FYI - new patients - bathrooms are located next to the elevator and make sure you grab the right key. I didn't know, I took the wrong key (men's) so explains why I struggled trying to open the women's bathroom. lol

    It's not like anyone wants a root canal. And hopefully, it's not something you need very often so…read moreit's really better to find a great dry cleaner or coffee place...someplace that will be a fixture in your life. BUT. When you need a root canal, you really need it. And when you really need it, you want it to go well. A wrinkly shirt or a cold cup of coffee may be annoying but a bad root canal, well, go rent Marathon Man and get back to me. I had a badly cracked molar and my dentist ground it down, took a mold of it and sent it off to the lab and me away. While I waited for the second appointment, the tooth did not feel right. The dentist sent me to Dr. Vignaroli for a consult. He didn't rush. He spent an unbelievable amount of time talking to me about my tooth, options, etc. He didn't try to rush me into it in case there was another explanation for my discomfort. Once I decided with him that yes, I needed the procedure, he couldn't have been nicer or more professional. He's not a 'dental corporation' with 4 patients numbing up as he races from chair to chair. He's single-threaded. You have his undivided attention. Highly recommended.

    Recently saw Dr Vignaroli a day after seeing my first dentist in 6+ years. There is a lot of work…read moreto be done on my teeth but this root canal was very urgent. My dentist called him and he made was able to see me the next day and his staff even called me 30 minutes later to ask if I would like an earlier appointment, which I really did. He was very thorough yet concise about explaining everything. At this point I didn't care what he was going to do as long as it would relieve some pain. He explained it in a way that I was easily able to understand and even made a point to tell me if he was talking too much just feel free to stop him, which I thought was funny because he knows much more than me. I don't know about other people but the longer I have waited to see the dentist my anxiety about it and fear has gotten pretty bad. After his incredibly clear explanation I already felt much morerelaxed. The thing that stuck out the most to me were his extreme precautions to make sure that I was properly medicated as to feel no pain. He seemed completely unconcerned with his own time as he waited to make sure I was properly numbed to be comfortable during the procedure. He worked incredibly well and fast, seemed incredibly perceptive of the slightest body language and made sure I was sitting in a comfortable position or any other thing and kept me informed through the procedure. I don't know how common this is but I think he took two x-rays during my relativdly short procedure just to make sure that he was 100% confident about the quality of the job he was performing. And kept me updated with accurate estimates about how much longer it should take. Last thing is about the temporary filling he placed while I wait to see my other dentist is done incredibly comfortable in my mouth and doesn't feel weird or effect my closed bite at all. Best dentist work I have ever had.

    I have no idea why this office has good reviews. I used to like seeing the dentist until I came…read morehere This is my family's account but i felt obligated to talk about my experience. I was referred for a root canal by my regular dentist earlier this year. The root canal office they normally refer to was booked so I found this office because it was close by. When I arrive for my appointment there is no one at the front desk so I sit down and wait for about 10 minutes before a dog comes to greet me. I love dogs, don't get me wrong, but it seems a little unsanitary and unprofessional to have an unleashed dog in a dental office. Who knows if she sheds and her fur is in the air going into people's mouths! I later heard people even talking about her biting others. 45 min after my scheduled time, Dr. Steven Williams comes into the room without introducing himself and is basically out of breath. He looks at my X-rays and says I need some work done but it's not even the tooth that's bothering me! I don't think he read any of the paperwork. He starts talking down to me about flossing and bad previous dental work I have in my mouth, all while using inappropriate words. I was speechless. I decide to have him do the root canal because I've been in pain for so long and do not want to wait any longer. Looking back, I should've just waited. This was the longest and most uncomfortable experience. He was incredibly aggressive and made every part of the procedure painful and almost barbaric. I've had another root canal a few years ago and it was nothing like this. After almost 4 hours in the chair with him jumping around seeing other patients, we are finally done. To my surprise he completed 2 other procedures that the front staff is billing me for. No one told me or quoted me for these and I never signed for them. I'm pretty sure billing me for these is illegal but it is definitely unethical. 3 weeks after the procedures and I am still having pain in the area. Dr. Williams just prescribed a lot of medications but nothing has helped. I decided to go to the original root canal office that I was referred to and they helped me fix the pain. Please don't waste your time and money here

    I left a longer review under Dr. Steven Williams yelp page. But I feel obligated to add here that…read moreI had a really good experience at this office. The staff were very kind and courteous - whoever answers the phones and sets appointments was so compassionate! Saw Dr. Fang for a root canal consultation but ended up needing a different procedure. Dr. Steven Williams spent HOURS making sure everything was just right. They have a CT scanner in the office for 3-D imaging! I can't say spending five hours at the dentist was "great" LOL but it was as good as it possibly could be. My out of pocket cost surprised me by how relatively low it was. They have nitrous anesthesia for those tough procedures too. I recommend this practice based on my experience!
