My daughter went with an infected tooth that needed to be extracted. I made sure I booked an…read moreappointment with an in-network provider and confirmed with Aetna before booking. The office did x-rays and scheduled her tooth extraction for the following day. During the visit my daughter's father called me and stated that the receptionist needed to speak with me regarding billing. She stated that we had to pay $106 before leaving the office even though I have a $0 copay and was then told that I would have to pay $1060.00 the following day before they extracted my daughter's tooth. For a tooth extraction??? with insurance????? I explained to the receptionist that Aetna had told me that I don't have to pay anything with my insurance. The receptionist then stated that the claim takes about 4 weeks to clear. So basically they would not do any work on a minor with an infected tooth without getting paid FIRST despite me having dental insurance that fully covered the procedure and visit with no copay. And then charged me an extra $106 that I was not required to pay. I am disgusted at the service we received and would not recommend them to anyone. This is wrong and unethical. It's difficult enough these days to maintain insurance for a family to only then be charged extra. SOUNDS ILLEGAL!!!!!!!!!!! I will be requesting my $106 back and the Aetna rep even stated that she was equally disgusted that medical professionals could treat people so terribly.

Fifteen minutes later ( fortunately my needs were due to nerves rather than urgency ) the dentist appeared. She came out with a roll of toilet paper and with her bare hands proceeded to roll off sheets of paper for me. I left the paper and her office. I will never return. I am a senior citizen perfectly able to take care of my paper needs and to hand me crumbled paper with her bare hands was not only insulting it was also a testimony to her lack of hygiene.

WARNING: In my experience this practice is highly unethical and very poorly managed…read more In short: 1. They overcharged me and refused to take any responsibility (despite me sending in bank statements as proof). 2. Once they had all my money, they became extremely unresponsive to calls and emails. 3. After I decided to no longer move forward with my Invisalign treatment (in which no trays had yet been made), they tried to keep my full payment for the procedure. 4. Once I got them to agree to a partial refund, they sent me a statement (on a word doc, not even billing software), with fraudulent or embellished charges, trying to scam me out of as much money as possible. I regret having ever walked into this office. In my opinion, Dr. Kossowan and Greg have low morals and no shame. If you search around for other reviews, you'll see I'm not the only person they've tried to scam money from. The longer story: I had a unique situation where I signed a contract for Invisalign, had the X-rays and scans taken, but then had to stop before any trays were made. I needed major dental work, which ended up taking almost two years. During that time, I made my downpayment and continued paying a monthly fee until my contract was paid off. Once I was finally ready to move forward, Greg, the office manager, tried to tell me that I would have to continue to pay a monthly fee--despite having paid my full contract while waiting to resume the treatment. While pushing back on this, I realized Greg had already charged me $557.50 in unauthorized payments past what my contract was for. Greg claimed he didn't think that was possible. I sent in my bank statements. Greg and Dr. Kossowan suddenly became very unresponsive...until I mentioned legal action. Even then, it took three months for them to refund the overpayment, though they claimed they were only doing it "in the spirit of accommodation." At this point, I had lost faith in the practice and no longer wanted to move forward with the treatment. I offered to pay for the X-rays and scans. Dr. Kossowan told me nothing was refundable. Despite never having actually received the Invisalign, she felt entitled to keep the full $7,800 I had paid her. Eventually, Dr. Kossowan agreed to a partial refund, but still wanted to keep over half my money. When I asked for a bill, it took her two weeks to send one to me. I showed the "bill" to another orthodontist and they were appalled. A few things of note from the bill (which is attached below). 1. $250 for "orthodontics photos" = three photos her technician took on his iPhone. 2. At one point, she tried to sell me on a $2,000 split for my jaw to help with TJM. I told her I was not interested in that--multiple times. Now she's charging $500 for a "TMJ X-ray" that I never consented to. 3. If the doctor had to do a "second Invisalign tx. plan" she only would've had to make adjustments to the teeth I had dental work on. Yet, that cost $1,000 like the first treatment. 4. $400 for four phone calls with my dentist. It seems to me that this practice is desperate to keep as much of my money as possible. Or perhaps they are financially unable to refund me. Either way, it seems they have resorted to lying and unethical behavior as a result.
