Our experience with Dr. Anne Kossowan and her team was exceptional. From the first time my son and I walked into the Pelham office we felt welcome. The office is clean and comfortable and very welcoming, and the staff is very friendly and professional. At every visit everything was explained clearly and next steps discussed. I cannot express how pleased we are with Dr. Anne and her team in the Pelham office are great. I would recommend Dr. Anne Kossowan Pelham office for your Orthodontist needs.

WARNING: In my experience this practice is highly unethical and very poorly managed.

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 the 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.

I cannot speak highly enough about my experience with Dr. Anne Kossowan and her team. From the moment my daughter and I walked into the office, we felt welcomed and at ease. The staff is incredibly friendly and professional, and Dr. Anne took the time to explain all of our treatment options in detail, ensuring we were fully informed before making any decisions. They are attentive to meeting needs, making adjustments, and ensuring we are happy with the progress.

We are thrilled with the results of the treatment. My daughter was completely transformed, and we couldn't be happier with the outcome. I highly recommend Dr. Anne Kossowan DDS

I'm 77 years young and just completed my Invisalign journey with Dr Kossowan, in the Manhattan office. The office is clean, and the staff is attentive and friendly. Dr Kossowan, is warm, thorough, patient, and always willing to answer questions. I highly recommend her!

Dr. Kossowan is a fantastic orthodontist and you feel sure you’re getting the best treatment possible.
There are no shortcuts taken or false promises made - just the best advice and top level care.
I would definitely recommend her to my friends and family (and you if you are reading this and considering her services!).
