I can't say enough good things about Dr. Southworth and his entire staff! My two daughters needed a LOT of dental re-alignment, including headgear and recommendations for extractions and periodontal work. Dr. Southworth was one hundred percent up-front, realistic and supportive through all six years of work! He has such a caring approach with his patients, always putting them at ease with a genuine spirit, and patient, understandable explanations of all treatments and plans. I highly recommend Dr. Southworth and his caring staff for any orthodontic needs.

Search no further, you are fortunate to have found an orthodontist who will give it to you straight( pun intended).
Whatever your needs or goals for your child, Dr. Southworth can assist you in understanding all of your options- including the option to not get braces! He is not a salesperson but an extremely well educated and experienced Orthodontist who will offer you and your child a caring and well supported consultation. His inclusion of your child in this process is perfection.
If you do proceed with braces, a kind and supportive team will make the entire process a walk in the park. I had two children who had very different needs. Both had incredible outcomes.
In terms of value, his pricing cannot be beat. There is a well detailed, comprehensive arrangement laid out before services even begin- this means NO SURPRISES! Payment was easy with an extremely reasonable payment plan.
Having his office so convenient is vital for ongoing care and his team makes it incredibly easy to schedule, interface with your regular dentist, and manage all the intricacies of any insurance you may have. They are a pleasure to deal with and I can honestly say after dealing with them for many years, every interaction was a joy.
Choosing the right fit for your orthodontist is critical and we are so blessed to have Dr. Southworth in our area. Some of my friends were not as fortunate and in the end paid more in time, money and stress across the board.
If you are able to utilize his services, you will be more than pleased with both the process and the outcome!

My two daughters are patients of Dr. Southworth and I would without reservation recommend his orthodontic practice and expertise. He and his staff are an absolute pleasure to work with. The office makes it their mission to run on time without anyone in the waiting room even noticing. All aspects of working with them come with ease. The rapport and relationship that Dr. Southworth builds with his patients is above and beyond. Many of his patients are in adolescence and like my daughters, may be apprehensive about the process and the extensive time commitment to braces. The trust he develops and confidence he instills among his patients sets him apart from the rest. We appreciate having his practice in Sterling and are forever grateful for the beautiful smiles that result from the commitment, but even more, the confidence within that evokes from those smiles.
