The facility is sea-themed, which I find pretty quirky, but the place is pleasant and clean. There is a t.v. on the ceiling above every exam chair, so you are entertained while you have your mouth probed. But most importantly, the staff and doctors are all extremely friendly and professional. There's nothing to be nervous about when going to the dentist anymore!

The best dental office in the area. Very professional, caring staff and docs. Highly recommended.read more

He gave me lots of options and explained everything clearly.

Can't wait to let him get started. I haven't smiled in a picture for 30 years. It's about time I don't hate my smile anymore

Within a couple of days I told Dr. Mack my teeth were moving. I continued to go into his office over the next several years with the same complaint and he'd keep adjusting my retainers. Fast forward to a couple of months ago. I now have a big space between my back two molars. I can't even put on the first plastic retainer I was given, that's how much my teeth have moved. When I went in to talk to them about it I was told I would have to get braces again with a cost of $2,500, and that's with a discount for being a previous customer. When I spoke with the new Dr. in the office about all of this I was told they don't even use the wire retainers anymore because "teeth move more with that type of retainer than with the plastic ones."-those were HIS words, admitting movement happens with the wire retainer, just as I had told them for years. So, now I have to pay them to fix a problem that was their fault in the first place! I will not go back to dr. Mack and I will never refer anyone to him again! It's obvious it's all about money! I am a middle aged woman. Insurance did NOT cover any of the cost. I wore my retainers religiously and now I'm expected to cover the cost of something that was preventable in the first place. TOTAL disappointment!! I will never return!!
