This review is specifically about the office staff and the owner NOT the dentists. They (the…read moredentists) are nothing less than amazing, however you have to go through the office staff with ultimate decisions, approvals, or denials made by the owner before you see the dentist. These people only treat you with respect and dignity if there aren't any financial issues and/or you don't owe them any money. God forbid a person should fall on hard times, or there's an insurance issue, then this establishment starts showing who they REALLY are, really fast. And what they are, are a pack of amoral, apathetic, inhumane, reprehensible, insensitive people who ultimately don't and won't care about your dental health problems regardless of how severe it is! Especially this location. They will tell you, you will not be seen regardless of how much pain you're in or the severity of an infection, and when you double check to confirm that was in fact what was actually said the secretary and office manager will gleefully say and I quote "yes!" This franchise especially the owner has made a disturbing 180 from what they stood for years ago, which was always putting the clients and their health first. They used to have top quality wonderful office staff who genuinely cared about each individual. Now that concept is so far removed from what this place has become and the kind of people/ office staff they have working in various locations now, it's nothing more than a distant memory. Bottom line, you're ultimately nothing more than a walking dollar sign and the more money you have the nicer they become and treat you with the utmost respect. Start owing them despite whatever the situation may be, the office staff especially the owner has absolutely nothing to say or do with you. You're LITERALLY not worth it.

Do not come here. Their front desk is ridiculously disrespectful. The first time we called, they…read moretold us they could give us a disk for my wisdom tooth scan, as I needed to take it to another dentist. They told us there were no extra fees (as our insurance wouldn't cover it) and there was a 10% credit card charge in person. After I had the scan, they told us we couldn't receive a disk. We asked why they told us different over the phone, and they denied any involvement. The next day we called asking to receive the scan however possible, and they told us they'd call us back but never returned the call. It was a holiday weekend, and we expressed urgency regarding this. We called later to further inquire until they put us directly on hold and then hung up after 15-20 minutes. We called after the long weekend, we called back to receive the scan, to which we received a singular screenshot of a 3D scan. This was unacceptable to my other dentist, and we demanded a way to view the scan in its entirety. In return they sent us an email with the same screenshot and a panoramic scan I also had there. Finally, I called and asked them to ask their boss who said he could give it to me, provided I was there with a thumb drive in hand within an hour. I had to drop everything to get my scan!

DO NOT COME HERE. They're sketchy about prices and billing and how much insurance is actually…read morecovering and the dentist is a very aggressive "Upseller" about dental work. I stopped coming to this location because they could be a bit cagey about what's going to be covered and always seemed really insistent that they do the work first and figure out what was covered after the fact I was offput but kept going for a while since at the end of every visit I paid out what I owed and according to them i was square. The event that actually convinced me to stop going was in 2021 when the dentist told me I needed braces and that my insurance "should" cover half of it. In fairness I have an open bite and DO need braces, however I also knew for a fact that they wouldn't be covered as that was one thing my HR rep mentioned specifically as not being covered. I remember the staff they sent in to discuss the cost with me REALLY tried to push it and kept mentioning that it was (It's been a while my numbers might be off.) $8000 but my insurance would cover half so it's REALLY $4000 and I had to remember that that would be spread out monthly over 2 years so REALLY it's $400/mo. The sale felt very aggressive and the general attitude felt like the goal was to get the metal in my mouth and THEN charge the insurance and figure out how much would be covered and charge me the rest after the fact. All good and well for them but i couldn't afford a known $4000 bill, let alone a surprise $8000 bill! And to be honest, i can't even afford the low ball $400/mo bill and, despite what they were saying, I was SURE it was gonna be $800/mo anyway since my insurance wouldn't cover that. I distinctly remember the doctor saying "yeah next time you come in we're gonna have to get you in braces" after I had ALREADY told them that it wouldn't be covered by my insurance and even as a monthly installment, even at the insurance covered price, it was not an expense I could afford. It really turned me off the way the doc tried to act like this was a decision being made FOR me and this was just gonna happen. So i just decided there wouldn't BE a next time to put the braces in and stopped going and let the whole thing go. My last visit was in March 2021. The reason I'm writing this review now in September 2022 is a SURPRISE $120 bill for fillings done in September/October of 2020! The office claims that though they cashed the checks from my insurance company 2 weeks after each visit they didn't notice the insurance was actually covering less than they claimed it was each time. And they just didn't notice until now. I ended up borrowing the money from a friend and just paying the surprise bill on card. But I keep thinking back to how hard they pushed braces and how they kept insisting insurance "Should" cover half of it, And how hard they seemed to be working to get the metal in my mouth before really being clear about the cost. Knowing how they handled the fillings bill I can only assume the braces would have gone the exact same way if I had just let myself get pressured into it! They would have put in the braces on the promise insurance is "Supposed" to cover half, done MONTHS, if not the whole 2 years of adjustments, getting the low checks but not recognizing that they were not being covered by insurance, gotten denied for 2 years and then popped up now in 2022 with a $5000 bill saying "Oh sorry turns out your insurance didn't cover 50% of it after all. But it's all done now so this is what you owe regardless. Covid ya know? Would you like us to do a monthly payment plan or send it to collections and destroy your credit?" Thank GOD I stopped going when I was turned off by how heavily they tried to push braces. ANYWAY regardless of their intentions you can't trust that the bills you get from here are ever the full amount of what you owe because they claim they don't actually compare what they got in the check from insurance to what the cost was until MONTHS (minimum 5 months since my last visit was 2021) OR YEARS (Since the bill was received 2 years after the first visit) after the fact. You may get a bill in the hundreds if you just had a few fillings but if you had extensive work done (Like brace or caps or a root canal) you could get a surprise bill in the thousands! "Covid" is not an acceptable excuse for having no idea what you patients owe you or what actually IS or ISN'T being covered.
