"I don't even know where to start by explaining how amazing this office is. First of all it's in a house and the setting makes you feel comfortable right off the bat. Second, the staff is incredibly kind and gentle and helpful. Trisha at the front desk emailed me back and forth about 15 times answering any questions I had. Dr. Cotham is so nice and calm and confident and made me feel 100% at ease about having a root canal. I just finished getting the root canal today it was quick and easy. I have dreaded this for so long and have such a relief that is over. He had his dental assistant Shelby were so gentle and efficient that I will be forever grateful. I am so impressed with them that I made appointments for my three kids. I highly recommend this office to anyone looking for a dentist! They are all amazing!"
