You can trust our experienced orthodontists to provide the highest-quality, scientifically proven care and treatments in a fun, welcoming, and warm environment that will always leave you smiling.

Smile confidently, no matter what your age

We recommend that children have their initial orthodontic evaluation with our team around age seven, to detect any issues that may require early treatment —and we invite them to join our Confidence Counts Club. Learn more

The most common time to transform a smile with braces or Invisalign clear aligners is between the ages of 12 and 16, when teens have most of their permanent teeth in place and take a greater interest in how they look and feel. Learn more

More and more adult patients are seeking braces and Invisalign clear aligner treatment for either aesthetic reasons or to correct shifting that takes place in the adult years, which if not addressed, can lead to problems such as tooth decay, gum disease, and abnormal wearing of tooth enamel.

Here’s what our patients have to say

Spencer T.

I love how the staff makes me feel so relaxed and don’t judge me.

Lilliana Jean M.

They’re great people to work with, and they have done an incredible job with my daughter’s teeth. We’re very happy with them and will be continuing our relationship with them when our next child is also ready for treatment.

Greyson T.

The friendliness of the doctor and assistants are what I love the most about Kristo Orthodontics. They’re always honest, professional and never pushy.

Andrew K.

Invisalign treatment works great for my age and lifestyle! I didn’t have to hide my smile during this last year of treatment, and it’s amazing how fast Invisalign clear aligners work!

Amber M.

My favorite part about my orthodontic treatment is looking back at old photos and seeing how much my smile has changed. It’s better than I could have imagined, and we’re not even at the finish line yet! The staff is so friendly and helpful and they make sure I’m comfortable and informed with every aspect of my treatment.
