This place is amazing! Kim at the front desk was so sweet and friendly and was very helpful helping me set up a payment plan. She also called to check in on me and my pain levels after my root canal and you can just tell she actually cared and it wasn’t just calling out of protocol.

I recently encountered a chipped tooth while consuming some food and was referred to Dr Omid Dianat by my dentist. I can't say enough good things about my experience with him and his support staff. Everyone was extremely friendly, personable, professional, explained things thoroughly and excelled in their areas.
