Patients Love Us!


Had my Invisalign done yesterday and I seriously cannot say enough good things about Amy. From start to finish she was so friendly, patient and made the entire process feel easy and not overwhelming at all. She explained everything so clearly, gave me so many helpful tips and genuinely took her time with me, you can tell she truly cares about her patients. Her energy was so comforting and positive, which made a huge difference. Absolute top tier experience. Amy is AMAZING and I’m so thankful for all her hard work 🤍✨

We love Oso and appreciate their hard work to make our boys teeth beautiful.Sometimes we have to wait awhile for our appointments but generally it's a well run place. Nice facility. Wonderful people. Decent prices.

I love this place!🩷 From the front desk to the technicians and the doctors, everyone is so welcoming and kind. The coordinator, Diana, is the sweetest—she took the time to walk me through the entire process in such a detailed and caring way. Britney, the dental technician, is absolutely amazing. She has the gentlest hands, and I honestly don’t feel a thing during my visits. The whole team makes you feel comfortable and cared for every step of the way. Highly recommend!
