Dr. Baumgartner is the best dentist, hands down. And Judy is awesome, the best team I had problems with my bite he fixed it when other dentists could not. Do not waste your time and money make an appointment with Dr. Baumgartner he will fix your dental problems. And the front office staff are awesome Sandra Julie but most of all Debbie she is the sweetest Lady I have ever met. Number one dentist he also travels to Mexico and treats kids with cleft palates for free every year and he helps our community. I am very lucky to find him it took a long time to find him. So if you need a dentist call Dr. Baumgartner you will smile again.

Best dental office in the SCV!! I have been a patient for over 25 years!! All my immediate family and extended family all go to see Dr B 😊. The entire staff is top notch!! From booking appointments, billing my insurance, to having procedures done I have always been extremely happy. I had to unfortunately move out of town, over 2 hours away but still make the drive to go to this office. Highly recommend 👍👍👍

I usually hate going to any dentist but Dr. Shimada is like the tooth fairy… not the one who takes your teeth and replaces it with a dollar, but the kind that fixes it to feel better and new again! I had sharp pains every time I ate because a fill broke and my original Prosthodontist is in San Jose. A friend recommended her so I called and booked an appointment right away.

When I got there parking was a bit confusing but if you do it once, you will get the hang out of it. I filled out the normal paperwork, the tech took me in to take an x-ray, then I saw Dr. Shimada! She asked me a few questions, examined the x-rays, explained what she say, then looked at my problem tooth. She is so friendly and has good bedside manners. She and her assistant did not rush me or make me feel like a “number” so I appreciated it. The best part is she is so skilled with her hands! I am usually a nervous wreck in the exam chair but her steady hands gave me confidence to get that numbing shot. After a few moments of prodding and drilling noises, she took out the broken fill and gave me a new one that no longer hurt when I bite!

The numbing wasn’t too bad either, I was able to eat a cookie a hour later… All in all, a really good experience and I would recommend her because she has such good bedside manner and the knowledge to take care of your teeth problems. Fear no more, come to her 🙂

Dr. Baumgartner has been serving our family of six for about 17 years! We are so grateful for his excellent work for our dental health. He has provided optimal care for each of us. Dr. B and his entire staff have treated us like family over the years, and we have felt very well cared for as their patients…and as friends.

I came in to Dr. Baumgartner’s office on a referral from my oral surgeon, Dr. Scaramella. Dr. Baumgartner’s staff were extremely pleasant and helpful. I was impressed with the office decor – they obviously put their $$$ into treating patients well, not providing a fancy office space (who needs that?). I had a terrible dental side effect from cancer treatment; the care I received at this office was just great. They took great care to study my condition and provide just the right care that was needed. I have since improved and the side effect has ceased, thanks to their expert care. Dr. Baumgartner is very well versed in issues of TMJ and jaw alignment; he will be our family dentist from now on. I had been going to a dentist who was very gentle and very nice but in cases where you need expertise and individual care, Dr. Baumgartner’s office is the place to go.

I would not go anywhere else!  When my elderly mother developed an oral infection a few years ago, I was referred to Dr. B. by a neighbor. When I saw the level of expertise, the care, and the gentleness in which the Dr. and his staff treated her, I knew we struck gold! I decided that I too would switch over to Dr. Baumgartner as well, even though he is not a participating doctor in my insurance plan.

Along with their wonderful staff, they really do great work here.  They take time with a patient and offer more helpful advice/answers than I’d experienced anywhere else. And the cleaning looks so good. Thanks, guys ❤️

I was referred to Dr. Baumgartner a few years ago. He first replaced my upper denture with a better looking and functioning upper denture that improved my ability to eat. After losing most of my remaining lower teeth due to heredity, Dr. B sent me to an oral surgeon specializing in difficult implant patients. After they consulted and agreed that collectively they could give me the dental school ‘perfect bite’, I proceeded with the surgery and with Dr. B’s expertise in implant appliances, I can now eat everything I like without worrying about breaking a tooth, losing a cap, or my denture falling out. It was a long process, but Dr. B and his staff kept me positive and on track. Also, my bite is now perfect, as predicted, for the first time in my life! I even enjoying smiling again! Going out to eat is now fun again. If I had to rate Dr. B and his staff it would be 11 out of 10. I highly recommend their office.

Dr. Baumgartner, I want to say thank you for doing such a beautiful job on Nely’s teeth; they look fantastic. We both could not be happier with the results. Also, thank you for cementing on my temporary crown. Debbie has been a joy to work with. You will definitely get our referral to anyone we can refer. Thank you.
