Had an emergency yesterday with my mom; she was in pain for 4-5 days and when I called yesterday Kelsey at the front desk was extremely helpful and got us an appointment for a couple of hours later! Wow, SAME DAY appointment!!! Ended up getting a root canal right away! We had doctor Gulley who is so gentle and knowledgeable about what she does along with her assistant Annie! Thank you so much to all the staff there who make this experience so amazing always!

My son recently got his wisdom teeth removed here. They did a great job from pre-to postop. They talked through all his postop instructions with me asked me if I had any questions and then his actual procedure took about 30 minutes after which I was able to go pick him up and he was wheeled out in a wheelchair he was sent home with medicated mouthwash, pain, medication, and antibiotic to prevent infection. We received a call the next day asking how he was doing as well. My son‘s recovery has gone well and so much better than my other son had at a different location where he got an infection and had a horrible postop experience with lots of pain. I can’t recommend this place enough! The staff were very friendly and answered all my questions thoroughly.

First time at this office. Spoke with Kelsey several times for a variety of reasons and she was helpful, professional and so kind. Only concern was my appointment was at 11:00 am and wasn't taken back until 11:55. It would have been very nice if someone could have at least came to waiting area to inform patients waiting there would be a delay. Dr. Simoni was great. Told me the procedure and explained everything that she would have to do. All staff was friendly and professional.

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.
