    Before Invisalign.

    Throwback to a year ago when I decided to transform my smile journey with Invisalign! Grateful to Dr. Colleran for guiding me towards achieving my dream smile. From crowded to perfectly straight teeth in less than a year - what a transformation! Feeling so much more confident and in love with my smile now. Shoutout to the amazing team at the office for making the entire experience welcoming and enjoyable!

    Two chipped teeth need a root canal and two crowns
    Marie C.

    I unfortunately chipped my two front teeth on a Sunday here in SLO. I didn't have a dentist when this happened so Monday morning I called around town and they had an opening! After filling out my new patient paperwork I got a water bottle filled with goodies and decorated with a nice ribbon! Just for filling out paperwork! This was a great gesture and made me feel really valued especially since I have never been rewarded for filling out paperwork. The whole office is really clean and nice environment. The entire staff is extremely nice and fun! They all made me feel really welcome and well taken care of which was nice considering my unfortunate situation! Since I'm still under my parents insurance they were really flexible and worked directly with my mom to get it figured it out. It took a lot of weight off my shoulders of having to be a middle man when I was already under a lot of stress with my teeth! To fix my teeth I had to get a root canal and two crowns. I heard a lot of horrible things about root canals so I was nervous but it really was not bad! They made sure I was really comfortable - I got a blanket and a pillow. They also have TVs on the ceiling with Netflix. So during my root canal I was completely relaxed, didn't feel a thing and I got to watch Beauty and the Beast! It was as enjoyable as a root canal could be in my opinion! They also did an amazing job with my teeth. I had two temporary crowns for two weeks and no one could even tell they were fake! And those were just the temporaries! Now that I have the permanent crowns, I think they again did an incredible job. They look better than my teeth before! I've also been here for a regular cleaning and it was just as great as my other experiences. I know some people don't like the dentist but at this office I don't know what you couldn't like about it!

    I now consider myself a vintage patient here! Dr. Ian Leopold is hands down the best dentist I…read morehave ever had! I originally saw his father, and Dr. Ian has inherited all the skills and patience that his father had. I also go in regularly for dental hygiene with Maria, and am just as happy with her work to keep my teeth looking and feeling healthy! Maria works quickly and I always walk away feeling like I have a new set of teeth. The office is in a beautifully restored Craftsman style house near Highway 101 and also close to Poly. It is clean, calm and relaxing. The front office staff is also attentive and patient. They can navigate the intricacies of billing and scheduling with cheer and ease. Dr. Ian also works on Saturdays, and they can fit you in should you have a dental emergency. They can also recommend specialists in the area if you need further work like dental surgery. The only downside for me is that they are out of my dental insurance provider, but I still get partial reimbursement. I would never go anywhere else because the quality of the work here is worth paying a bit extra for!

    I had been going to this dental place for about 4 years and had extensive work done that amounted…read moreto almost 10k in that time period. At first, I overlooked a lot of things that my gut was telling me. One instance, I inquired about something different from what I came in for, the dentist did work on it right away to my surprise, and of course deducted the cost from my prepaid funds. There were billing errors that happened more than once, being overcharged, even when they say you get a discount. Getting my refund took time because of "corporate" office approval wait. Then I get charged for "periodontal" work $184 when I received basic cleaning - I know full well the difference. I specifically told them that I only want cleaning. With my last appointment I called first to make sure, again she said $184, and I said I want cleaning only then qouted $131. Ok so I go in for basic cleaning, upon being seated, the hygienist said that I'm due for an Xray. I told her I'd rather not at this time as I had extensive work done in their office already. She said my last xray was a year ago. I said it's not necessary, then she calls in the new dentist whom I never met before, and I felt ganged up on both convincing me. I said I'm willing to do it next time or in a year. I asked if they will do cleaning without Xray for now, again they insisted with no regard to what I wanted. So I stood up and quickly walked away. The way they made me feel was awful. This was the final straw for me. I definitely relate to what others are saying about Broad St Smiles. It's a corporate dentistry in which the main focus is to generate revenue as much as possible rather than genuine patient care. Yes, BUYER BEWARE!

    My wife and I have been going to this dentist for about three years, and recently we began to get a…read morebad vibe. Firstly, when he enters the examination room, he fails to greet me or ask how I am doing; instead, he goes directly to examining my teeth. Secondly, he was pushing hard for me to purchase a $450 mouth guard, even though I have no indications that I am grinding my teeth. Thirdly, he told my wife that she needed a root canal; however, a follow-up examination by an endodontist indicated that a root canal was unnecessary, and that only a bite adjustment was needed to eliminate her issues. Finally, he insists that I have X-rays every two years, despite the fact that I am not experiencing any issues. My primary care physician does not require a full-body X-ray every two years. In conclusion, I don't trust this dentist and suspect his treatment plans are driven more by a desire to generate revenue than by patients' actual needs. Caveat emptor.

I explained that my wife is terribly dental phobic, and also, we needed a dentist who'd be welcoming of our family, part of the LGBTQ community. The immediate response was "no problem." So we made an appointment for my wife's broken crown. If there is a perfect dentist, Dr. Yoon is it! She has a bubbly personality that makes you feel at ease. She has a good sense of humor, too. She was very gentle during the hardest parts, like numbing her mouth and drilling. I liked that she kept telling us what she was going to do next, and about how long that would last. All of those things made this visit much less anxiety-producing for my wife. Her dental assistant was also very nice and accommodated my need to remain with my wife. They both treated my wife with the utmost respect, and yet gave her the extra TLC she needed. I never sensed that they were in a hurry to get to the next patient. They took good care of my wife, and that's all that mattered. The front office staff are also super nice, helping us navigate insurance forms and medical paperwork with a smile. We feel very much welcome here, not just as a paying customer, but extended members of the family. I will be booking my next regular visit with Dr. Yoon, and this will be our family dentist from now on!

We had recently found out about digital crowns through an experience my husband had in Eugene, Oregon and struggled to find a doctor in our area who is capable of producing these kinds of crowns. We landed on Dr. Wong in San Luis Obispo. He has all the latest technology & is able to create the crown in the office in under two. So what would normally take 2 to 3 visits using a traditional crown, takes just a few hours with Dr. Wong. No dentist I have ever been to has been able to completely numb my mouth. Dr. Wong numbed it on the first try, which was a huge relief to me. I felt absolutely no pain or discomfort during this procedure. His office staff and assistants are extremely helpful and very friendly. He is a bit pricey. He is out of network so we did not get the full benefits of our dental insurance, but he is definitely worth the price.
