    I will never have a single bad thing to say about this place. The staff is truly filled with joy,…read moregrace and kindness. They treat you like family and even though I've become a regular, I've also seen them treat brand new patients as family as well. They truly care about their patients. And it doesn't hurt that their new building is as BEAUTIFUL as they are! They've made a move to a new location and they took the time to make the environment truly feel like home.

    Went to this dentist for years- over a decade actually. Chelsea always did my cleanings and I was…read morealways pretty happy with her. One doctor had left this office and they got a new guy. Ever since then things were different. The last two times I went for a simple cleaning I was charged around $70. First time I was told it was for Xrays. Weird I had to pay out of pocket but I just accepted it. Went back earlier this year and paid MORE than the last time, it was $90 something for just a cleaning!? Then suddenly Renee informs me I'm out of network. Couldn't have told me this before? Especially considering I've been loyal to this office for 10 years?! I called to question it and they said they might've charged me for my DADS exam or something. I haven't been under his insurance in years. Renee was out of office so the girl told me they would call back and refund some of it. This was five months ago. Needless to say that refund never happened. Thanks okc smiles, I won't ever be back. Super upset I've recommended people here in the past.

    My wife went here 3 times. The dental work was OK but the office management and billing is very…read morequestionable. Karen at the front desk doesn't seem to care about the patients. At least half the time when you call, no one answers the phone. After my wife's first visit, I asked for them to provide a treatment plan before we scheduled any more work. After about 2 weeks, I sent an email requesting the treatment plan. However, Karen never sent it and finally I had to go up there to get it. After the first visit and receiving the treatment plan, I realized that there were major billing issues. They were suppose to be a Network Dentist for my Insurance (GEHA FEDVIP High option), but all their billing looks like they are a Out-of-Network Dentist. There are massive "Not Covered" amounts that normally only occur for Out-of-Network Dentists. I questioned this to Karen 3 or 4 times (at least twice via unanswered emails) and in-person. I also sent a letter to their billing department who didn't respond. I also called their billing department about the billing. They said they would call me back but they didn't. My wife went there a total of 3 tines before I told here she needed to return to a dentist that In knew was a Network dentist. For these 3 visits, I believe I paid or will pay over a $1000 for Not Covered charges that normally only occur for Out-of-Network dentists. I guess I will have to file some type of formal complaint to see if I can get some of my money back!

    Dr. Griffith and his staff are very professional, friendly and compassionate. I am so glad I found…read morea dentist and office that I really like.

    Dr. Leemaster and his staff have been amazing! I always receive a friendly welcome from everyone…read more Prior to my appointment all charges are explained and printed out. When I come in for my appt they always tell me what is owed before I begin so there are no surprises. Overall a great experience!

    I've been a patient here since 2016 and have always kept up with my cleanings four times a year…read more For years, the care was great, but since management changed, the quality of service and professionalism have gone downhill. Over the past year or so, I've had repeated billing issues -- told I had a large credit and owed nothing, only to get a bill the next month, then another for the same amount even after calling to fix it. I also had my worst filling experience here, where the cavity got overfilled, changing it's shape, and ended up getting a much more expensive and painful root canal to fix it. Today was the final straw. I had a 4:00 PM cleaning booked months ago and took time off work for it. At 2:06 PM, while in a meeting, I got a text asking me to confirm because someone else wanted my slot. Fourteen minutes later, they canceled my appointment via voicemail and gave it away -- no warning, no call, no mention of any new confirmation policy, not even the courtesy of enough time to check my phone. In nearly ten years, I've never missed an appointment and have rarely replied to reminder texts (I literally only have record of confirming once out of 4x a year for a decade), so this came out of nowhere. When I called, the manager was dismissive and acted like it was normal and acceptable to cancel a pre-scheduled appointment an hour before, which is absurd and awful customer care. People have jobs and responsibilities. Canceling with less than two hours' notice because someone else wanted the time I already committed to shows no respect or care for patients. Even their billing department takes longer than 14 minutes to return a call. I truly love several of the hygienists and have been loyal for years, but the management's lack of compassion, accountability, and basic customer service skills has made it impossible to recommend this office anymore. If you want a cleaning today, they might bump another patient for you... just don't count on keeping your appointment.
