What Our Clients Say About Us

  • "I visited the office to have my periodontal work done. I visit every 3 months for this. Debbie does a wonderful job cleaning my teeth and also advises me regularly what I am doing right and what may need more attention. Dr. Mazzella always stops in to take a look at my teeth and just chat for a minute or two. I am very comfortable in this office as everyone, including staff, is very friendly but also very professional. Dr. Mazzella is the best dentist I have been to in a very long time - I have been going to his office for almost 6 years and it has been a wonderful experience. I always recommend him if anyone asks about my dentist."

    Adrienne M
  • "Dr. Mazzella and his staff are the best!"
    Gayle G
  • "I came into the office early on a Monday morning without an appointment with a tooth emergency. I thought the best I could get not bein in their schedule was either wait a long time to get seen between other patients or an antibiotic prescription and a time to come back later in the week. Instead, I was seen within 10 minutes and was done in a little over an hour. Dr Mazzella is the best and his team is the greatest in compassion and friendliness."
