This is the best dental practice I've ever experienced. Dr Florendo is amazing! You would be hard-pressed to find a dentist who is more kind, patient, and gentle. He did three fillings on me this morning (I had been neglecting my teeth for quite some time) and told me that one of the cavities was pretty deep and doing the filling might be painful. He was so gentle I would have been able to take a nap if I didn't have the sound of the drill in my head. Seriously, an incredibly nice man and a wonderful dentist. While I'm at it, kudos to his Dental Hygienist, Amir. I needed a deep cleaning, which can be very uncomfortable. Again, the gentle hands of an angel. I heartily recommend this dental practice. read more

Our experience started going downhill after the retainer consult on 2/18/2026, and it has been extremely frustrating and concerning ever since. According to our original contract, retainers were priced at $300 for a pair. However, at the 2/18 visit, we were told the cost had increased to $600 per pair, or $1,250 for a set of four. This significant price increase was never clearly explained or agreed to. At that appointment, I acknowledged the cost of the retainers and clearly stated that I could not proceed at that time. I specifically instructed Aylin that nothing should be ordered without my approval and that I would call back to confirm before moving forward. I was also told my child needed to be scanned before retainers could be ordered, and to my knowledge, no scan was done that day. We then scheduled a separate scan appointment for a later date. Based on the treatment process, my son should have had his teeth scanned a total of three times--initially, again for refinements, and a final scan for post-treatment retainers. The lack of clarity around whether this final scan was completed further adds to the confusion and concern about how his care was managed. Before that appointment, I called the office and spoke with Aylin to confirm that no retainers had been ordered. I again clearly stated not to proceed with anything. Despite this, I was later told the retainers had already been ordered anyway. I was then pressured to pay and even threatened with collections. This is completely unacceptable. There were also serious concerns with the quality and oversight of treatment. Before my child was even evaluated by Dr. Manassra, we were told by Anna (who is not a dentist or orthodontist) that his Invisalign treatment was complete after the first 15 sets of trays, despite our concerns with the results. When Dr. Manassra evaluated him, he confirmed that additional treatment was necessary, and my child required 12 more aligners. Although he was scanned for the new trays, we then waited nearly three months for them to arrive. During that delay, my son's teeth began to shift, which undermined the progress already made and raised concerns about continuity of care. Additionally, at routine appointments to receive trays, my child was not consistently evaluated by an orthodontist and was instead simply handed the next set of aligners without any clinical assessment or provider oversight. On his final tray, my son was seen by a different orthodontist on 2/18--since Dr. Manassra was no longer with the practice--who stated that his teeth "looked good" and that his treatment was complete, despite our ongoing concerns about his bite and overall alignment. The focus of that visit was then shifted toward obtaining retainers. On 4/15, we had an appointment with another board-certified orthodontist to obtain a second opinion. During that visit, it was determined that additional refinements were still needed due to my son's teeth and jaw not properly aligning. We agreed to transfer care, and their office called on our behalf to initiate the transfer. During that call, they spoke with Aylin, who stated that the Invisalign case was non-transferable, that my son's treatment was marked as "complete", and that four retainers had already been ordered for $1,250. She also stated that if we did not pick them up, the account would be sent to collections. She told the office staff at the new orthodontist this and this was the first time I became aware that the retainers had been ordered despite my prior instructions not to proceed. When I later contacted Aylin directly, I questioned how the retainers could have been ordered when we had canceled the scan appointment scheduled for 4/1. She stated that my son had already been scanned on 2/18 and that we had signed a form authorizing the order on that day. This directly contradicts what we were told at the time--that a separate scan appointment was required before any retainers could be ordered--and to my knowledge, no scan was performed that day. I requested proof of the scan and she basically said to get it from Invisalign. Based on these conflicting explanations, it raises serious concerns that a prior scan may have been used to initiate or justify ordering retainers without clear consent, potentially placing us in a position where we were later pressured for payment. This lack of transparency and consistency is deeply concerning. After over 10 years as patients with no prior issues, this experience--especially after Dr. Florendo left--has been a complete breakdown in communication, accountability, and trust. Changing prices from the original contract without clear consent, ordering treatment without authorization, providing inconsistent information, failing to ensure proper orthodontic oversight, and pressuring patients into payment is not acceptable. They say one thing and do another. I strongly advise others to get everything in writing and not rely on verbal assurances. read more

They made a crown for my son in JANUARY And they keep on asking him to come back for scans. But when mu son comes in to fit it doesnt fit. It's almost MAY now and still they want him to come back for more scans. When i called the insurance if i can just transfer to a different dentist, they said that they were billed already even though my son still doesnt have a crown! It's been 4 months already! And they keep on blaming the lab when really they're not competent in doing the scans that's why it doesnt fit! read more

I booked an appointment through Open Care for this location but never received a response from Great Smiles Dental.

Be cognizant of your charges, if you are a patient at Great Smiles Dental. After reviewing my insurance's explanation of benefits--which I regrettably never do--I saw an overcharge of over $100. After calling the office and speaking with Selena, the office manager, she apologized and stated I would be receiving a refund check. When it arrived, it was from my dentist's personal checkbook--not from the practice. I thought this was odd, but just a clerical error. At my last cleaning, Selena, quoted me the price for a cash-paying teeth cleaning. She stated it included the cleaning and an x-ray. I explained to her that at my previous teeth cleaning, I paid for an x-ray, and wasn't due for another until my following appointment. She stated to me that it was the same rate, regardless of whether I had an x-ray, or not: "Just get an x-ray. You're paying for it, anyway". I explained I didn't want needless x-rays. She said it was my choice. I paid the full amount. A few days after my appointment, I called a friend who is also a cash-paying patient at that office. I told them the rates had gone up and I wasn't sure if I was going to return. My ftold me that Selena was not truthful when she quoted me the amount, stating it was the same regardless of an x-ray, or not. My friend stated she always paid two separate amounts. I called the office and they stated they would credit my account for my next cleaning. I really like my hygienist, so I decided to agree to the credit, and go for one last cleaning in a few months. However, after much thought on the overages, I decided I would not return. I called multiple times asking for my refund. Each time I called I was told Selena, was not available. They stated that they would relay the message. I never received a return phone call. Nearly a year later, and I have not received the refund. I have since filed a complaint with the Dept Of Consumer Affairs. read more

The dentist has heavy hands and is not very friendly. He judges you for not taking care of your teeth instead of just finding the best solution. He explained my condition while he was on his computer and I was lying on the chair. I have to look up and twist my neck because he was above my head. If he is a good and sensitive dentist, he could have spoken in front of me and eye level. The staff will call you non stop day and night even if obviously you don't want their business anymore. I would not recommend this clinic. read more

Will not go back! I've been searching for an amazing Dentist I thought because we are in a small town he would be great! I was wrong! I went in with pain and I still have pain!! I did tell him that. Instead I got a paper to see someone else about another tooth problem which by the way is not hurting me. He said my primary should be the teeth he suggested come first!? I left with pain I still have pain he did not follow up with a check up or come back in to fix my current pain! A total waist of my insurance and time! I will not come back. read more
