Dr. Justin, the front desk staff made the process seamless. The initial x-ray and evaluation process and taking and all of the high-tech State of the Art equipment was very impressive. Dr. Justin took his time explaining all of the findings perfectly and in terms that were easy to understand and he made me feel very welcome and comfortable and Confident in his Expertise. The amazing dental hygienist who worked quickly and efficiently and left my mouth and teeth feeling squeaky clean I highly recommend this establishment definitely as the best Dental experience I have ever had in my life!

I was referred to the office by a friend of mine. Everyone was so friendly and helpful! The front office was so welcoming as a first time patient. I was seen by Dr. Justin who explained everything to me and didn't make me feel bad for not being in the dentist for awhile. The back office did great taking my xrays. I struggle when they take them, but the assistant was very patient with me and helped me through it. Patrick did my cleaning - and now I know why my friend recommended them. Patrick was thorough and answered any questions I had. He made me feel so comfortable! They offered me payment options to help me get the best treatment plan for me and gave me payment options as well. Loved, Loved, LOVED the office!!!

What is the Mouth-Body Connection® ?


The Mouth-Body Connection® refers to the link between oral health and overall health, and the role that the harmful bacteria and inflammation in our mouths play in chronic, systemic disease. That’s why it’s time we talked about more than your teeth. Our office prioritizes your overall health as it relates to your oral health. When we care for your smile we’re also looking out for your entire self.
