What Our Patients Are Saying

“Sound Orthodontics is wonderful! Every staff member I’ve encountered has been great, and I’m loving the progress on my teeth. As an adult, the invisalign solution they offer is a great fit for me and my lifestyle. I’m seeing quick results and completely attribute it to the expertise of the doctors at Sound Orthodontics!”


“Dr. Jack was very informative about the process of getting braces and very kind to our daughter making her feel like she was part of the process and made sure she understood what was going on and asked if she had questions.”


“I am over halfway through my treatment and I am loving it so far! I have seen amazing results. I really do recommend Sound Orthodontic if you are seeking a smile change!”


“Amazing place and great team willing to help and providing all the details you need to hear. They were all very kind and positive. I have started my journey and had a lot of questions that were all answered thoroughly with professionalism and accuracy. Dr Jack and co. have a lot of experience in the field and will treat you with care and responsibility. They know what they are doing, and that gives me peace of mind. Because it’s a long journey in straightening your teeth you will have to choose carefully. I’m beyond happy I chose Sound Orthodontics! Highly recommend!!”


“This is the best orthodontist I’ve been to by far. Every single person that works there has the very best attitude. They are very quick and efficient at taking you back on time for your appointment. I never wait more than three minutes in the lobby for someone to take me and my daughter back. My daughter loves going to the orthodontist because they treat her so well and they’re so nice to us. This is the orthodontist to go to if your kids have had bad experiences in the past because they’re not rough at all and they make sure you’re nice and comfortable and they don’t overwhelm your child.”


“My daughter and l love the place. Everyone at this location very friendly and helpful. Such a wonderful experience with you all.God bless you all.Thanks”


“I came in for an evaluation for possible correction to improve periodontal issues. Both the assistant who took photos and x-rays and Dr. Kortne Hou were exceptional! Friendly, efficient, capable, explained everything perfectly. Although orthodontics aren’t going to help in my case, I would recommend to anyone seeking advice or orthodontics. 6 stars!”



“2/3 of my girls come here… I have been very happy with everything. Highly recommend this office. Amazing staff too.”


“Friendliest staff anywhere. Always smiling and happy to assist. Remembers the boys and asks how Scouts and school are going and if they have any thing planned for weekends and summer. Just can’t say enough nice things about this place.”
