What Our Patients Are Saying
It's rare to have that doctor experience where they truly understand your individual situation and can finally explain why you have these problems, even when other doctors didn't believe you. I had that experience with Dr. Keesler. He explained so many of my unanswered questions. I can tell by his recommendations that he cares about what's in my best interest. It's so refreshing to have a doctor so intelligent who really cares about helping his patients. The staff is very friendly and kind.
We love Keesler Orthodontics!! The office is fun and colorful; which completely puts my son at ease. But the best part is the staff… they're kind, knowledgeable and have treated us with respect. Would recommend them to anyone!!
After seeing multiple dentists in many states, my orthodontics hold up to exceptional standards 15 years later. My dentists repeatedly comment on the straightness of my teeth and placement of my permanent retainer 18 years after my braces were removed.
Amazing staff! Make even adults feel great! Even through the pandemic, their service was amazing. The cleanliness of the building was too. I will always recommend Keesler Orthodontics! Thank you all for your amazing hospitality and amazing work you have done!
All 3 of my children went to Keesler Orthodontics! Dr. Jeff, Dr. Marissa, and the entire staff are great!! Always happy and ready to help. We have one more child to get braces and she will definitely be going to Keesler to complete our perfect smiles!!
Best Orthodontist in the area! Very professional, knowledgeable and do great work! I wouldn't take my kids anywhere else.
Both of our kids have had orthodontic services at Kessler Orthodontics and the experience could not of been better. The staff has always been professional and kind and the doctors as well. Thank you so much for a great experience! I can't recommend them highly enough!
I'm so impressed with Keesler Orthodontist! The staff is always friendly and they go out of their way to make sure everyone has a positive experience. They called the day after my daughter's expanders were put on to check how everything was going and even sent some coupons in the mail for some free shakes! My daughter isn't afraid to go and looks forward to her next appointment! I would highly recommend them!

Friendly and informative. Always great customer service and keeps us informed of every step of the orthodontic journey. Could not recommend them more.
Compared to other places I've been, Keesler Orthodontics is more informative and reliable. Everything was explained to us very well. We were left with no doubts after the examination and started the treatment immediately. The doctors and the staff are all very friendly and helpful.
