Had a teeth whitening treatment done. It’s a long process, but I got through it the best I could. A thought I had was a small TV on wall for distraction, or lap top to hear a pod cast or other… would help to distract from the duration of this process. The staff is so kind, caring, professional and accommodating! Thank you staff for all you do! I’m very pleased with my experience here!!

Forest Gump was right, ..."life is like a box of chocolates.." It even holds true for Dentists, i.e. you never know what you get until the box is opened and one is picked! And boy did I pick well!! Choosing Duo Dental over the many dentists in my area was the traditional "crap shoot," and I got lucky. This was my first visit to the office and the first step into their office immediately gave me positive vibes...which continued into meeting the administrative staff (Jennifer, Steffany and Carol), onto Hygienist Rosanne ("Roe"), and then Dr. Mullin. Every one of them earnestly appears to love their jobs, which easily has translated into doing the best for clients and the reputation for the company. As Roe examined and cleaned my teeth, she explained everything that was being done, going well beyond what any other Hygienist has done for me in my many years visiting dentists (professional beyond expectations). Meeting with Dr. Mullin was additionally pleasant. He detailed the findings of the x-rays taken and highlighted the limited work that needed to be performed. Both Roe and Dr. Mullin were both highly professional without any appearance of being patronizing or taking up too much of their time. They are there for their clients...ones who have either found a "new home," or those who don't want to leave. I could not be happier of the choice I made. Hank D

Went in for a root canal. We all know how those go. This root canal was the best i've ever had. No pain, and I mean, no pain at all.Except for little stick , you get to numb you up. I'm telling everybody, I'm such a baby. This has been the best visit have ever had at a dentist office. I'm telling everybody about Dental Duo. Go you won't be disappointed. Everyone is amazing.

I recently visited this dental practice for the first time, and I had a very positive experience. From the moment I walked in, the staff was welcoming, friendly, and professional. The office itself was clean and well-organized. I didn’t have to wait long before being called in, and the dental staff took the time to explain everything clearly before starting any procedures. They were very attentive, making sure I was comfortable throughout the visit. Overall, this was a great first experience, and I would definitely recommend this practice to anyone looking for a professional and caring dental team.

Excellent Office! My first time in this office for a routine visit. Professional, responsive and friendly group. Warm welcome by the front desk staff, hygienist and doctor. This office is spotless. You can breath clean air as you walk in. I had an amazing experience and I already booked my next appointments. Thank you Duo Dental!
