    “Fantastic dentist! I’m so happy to finally have someone close by who does such a great job!”


    “As someone who was really afraid of going to the dentist, I can not recommend Dr. Happiness enough! Went in with a sore tooth that turned into the need for a root canal. She took care of it that very same day and I felt NO pain whatsoever. So happy to have found a dentist that I trust 100%”


    “Love this dentist. I have been with her for several years. She is professional and truly knowledgeable. She cares about her patients and it shows in her work. The office is clean and modern and her staff is welcoming. There was no long wait which is important to me.”


    “I have had an amazing experience at Happy Smile Dental and recommend Dr. Happiness to all my friends and family. The entire office staff is so kind and friendly. Dr. Happiness is gentle and patient, she takes her time to thoroughly explain the work she is going to do.”


    “I'm grateful to have gone to this place, I had the best and comprehensive care, the dentist made me feel much better and was very considerate to me because I do not have insurance, Definitely recommend it!!!!!’


    “I had an excellent experience from the staff to dentist! The office is beautiful and clean. I highly recommend Happy Smile Dental!”


    “I called as a new patient and she was able to see me the very same day! Friendly staff, the office was immaculate, and a great cleaning! Highly recommended! Amazing experience!”


    “I had to have four teeth extracted. The experience was pleasant. They were very hands on in my recovery. Thank you Happy smile.”


    “One of the best dentist I have ever been to! Have been coming for over 8 months now and they always do great work. Will continue to come here as long as I live in the area. The dentist is very gentle and makes you feel comfortable.”


    “Very, very friendly place! I came into the office very afraid and nervous. The nurses were very welcoming and lovely to work with. Dr. Happiness is just that! She works with you to make sure your smile is at it's best. I'm no longer afraid and I'm making her my forever dentist!”


    “Dr. Happiness has treated myself, my husband and our two small children. She and her staff have been accommodating and pleasant in every way. The office is clean with updated technology and she always takes time to explain procedures and processes. She's a gem!”


    “Both the staff and dentist are all very pleasant and professional! The dentist is funny and inviting and it makes a not so pleasant experience much more enjoyable. I had some fillings done and she made sure there was no pain (besides for the unavoidable pinch before the numbing shot, of course).”


    “Dr. Happiness is really amazing. She takes her time explaining the procedure and repeatedly asked if i have any questions to ensure I understand every step. The staff is just as great and very friendly. I strongly recommend Dr. Happiness”


    “Very thorough and caring dentist and the staff is wonderful! They helped me understand my complicated insurance plan, and broke everything down for me clearly. I had a root canal done, and Dr. Happiness was very strategic on how to best tackle the work that I needed done, and it was a very smooth process. Would definitely recommend Happy Smile Dental!”


    “Excellent experience . Staff was friendly , office was clean. The dentist was gentle and very knowledgeable. I’ve already recommended a few friends to this office ! They’re great!”
