What a wonderful experience and an amazingly clean and modern facility. I dread going to the dentist, but this was by far the best experience I’ve ever had. My husband and I recently moved to the area and we really lucked out by having found Greenwood Dental. Dr. Nikol was very thorough and detailed about the condition my teeth were in and what the game plan was moving forward. Happy to have found such a great dentist in the area!

I am always greeted with friendly smiles. So much genuine care is put into every visit. The dentist and staff prioritize each patient’s comfort and they deliver quality care. And their dog, April, is beyond precious. I have been recommending them to everyone.

The staff here were so kind and friendly. They took great detail in examining my teeth and gum health. They also were thorough with telling me what to expect during my visit and what recommendations I should have for future appointments. Overall, like the small motto that can been seen under the name of their business, I had a great reason to smile with my care here.

We had such a wonderful experience at this dental office! From the very beginning, the scheduling process was easy, organized, and welcoming. The entire staff creates such a warm, family-friendly atmosphere that immediately made us feel comfortable. I especially appreciated how patient and kind they were with my kiddos during their cleanings. The team made sure they felt relaxed and comfortable the whole time, which means so much as a parent. My husband and I also had very thorough exams, and the dentist took the time to explain everything clearly and create a game plan for our next steps instead of making us feel rushed. You can truly tell they care about their patients and want the best for your family’s dental health. Highly recommend to anyone looking for a caring, professional, and trustworthy dental office!
