When we started going to Lumia dental, we were extremely pleased with how friendly and competent…read morethey were. It was an added bonus that this was a female owned and run company (of which alas they are still way too few nowadays). Their patient care is excellent and as far as any dental work is concerned, I would highly recommend them. However, as their business grew and expanded, I was starting to worry about what this would mean for their patients. My worries did eventually come true: from a patient based practice, it turned more into a corporate business, and with it, the desire/need for higher profits. As a result, they decided to no longer accept our insurance (Guardian dental, a major dental insurance company) because, according to them, their low fee schedule did not allow them to provide the best care for their patients. Now, that latter is just rethoric, for they were doing an excellent job. Why would that need to stop? No, it was because Guardians fee schedule did not make them enough profit. The way it works is as follows: a dental practice can determine its own fees for various procedures. An insurance company, through collective bargaining, can then negotiate for a reduced schedule for their clients (depending on the local competition). So, accepting an insurance first and foremost means to agree to the collectively bargained fees. While getting less profit, it means a much larger potential client base. This is the power of collective bargaining (which would be so much more effective if health care in the US would be universal, like it is in many other countries and, as a result, also much affordable). For Lumia, however, loyalty to their patients was not deemed as important as getting more profit (perhaps because of the increased costs of having expanded the business) and so they dropped Guardian as one of the accepted insurances. To give one example: our insurance pays the full fee for a cleaning every 4 months. However, they now raised their fee for a cleaning, making us having to pay more than $100 for something that was previously free. And you can guess that with more involved procedures, the out-of-pocket costs gets up even higher. That is why we had to leave Lumia as clients---essentially being pushed out as not being affluent enough clients that do not mind paying much more than they used to---and we now found an equally competent dental clinic in the neighborhood which does accept our insurance. I can only assume that we will not be the only patients leaving the practice, and in the long run, this might seriously damage Lumia (unless they can find enough wealthy clients in the downtown area).

While you sit in the chair getting your teeth whitened, they give you these yellow tinted plastic glasses that supposedly protect your eyes. I was doubtful because they look like they came out of a cereal box. When you're done with the procedure, you take the glasses off and your teeth look pretty white. A glass of lemonade would look white at that point too - after spending about an hour seeing everything tinted yellow. When my eyes had adjusted and I got home I realized my teeth hadn't whitened at all. Tricky! They also are very pushy to get you to buy another session at a discount. The discount only applies if you pay on the spot, and they really press you. I paid in the office for a second session that I didn't even bother going back for because it's truly a waste of time for minimal results. They sometimes offer a discount for positive Yelp reviews, so keep in mind that a lot of these 5 stars are from people who are getting some money back and haven't had enough time to realize their teeth are same as always. As a final insult, my teeth were incredibly, painfully sensitive for the rest of the day.

He was able to give me an action plan that provided me immediate relief after over three years of pain and suffering at the hands of NATIONAL DENTAL's doctors Fischler and Ganz, who spent 3 1/2 years, gaslighting me and telling me that there was nothing wrong with their work, and there was something wrong with me! Dr. Krochak and his associate Dr. Komar developed and implemented an affordable plan to help me. They did not throw up their hands, nor did they debate or defend against my complaints. They truly listened and wanted to help me, and they did! I urge you to consider the reason this practice for all of your dental needs!
