Doctor Leonard - Clear Aligners

Customized aligner therapy is a great way to undergo orthodontic treatment. We have been providing Invisalign® since 1999. We do more Invisalign® than any other Orthodontist in the area.

Invisalign® is a simple invisible process to straighten teeth, using a progressive series of aligners. Each aligner is designed to move the teeth a specific distance, in the process of moving the teeth from where they are to giving you the great smile you have always wanted.

Straighten Teeth Without Braces

Using a series of clear, customized, removable appliances called aligners, Invisalign® straightens your teeth without wires or brackets. It’s virtually undetectable, which means hardly anyone will know that you’re straightening your teeth and results can begin to show in just a few months. Plus, you can still eat all of your favorite foods.

Orthodontic Scan Demo

Save time and get more accurate results with the use of an iTero® Digital Scan.  An accurate scan helps each aligner to be precisely calibrated and manufactured to fit your mouth at each stage of your treatment plan an Invisalign® aligners are designed to move your teeth in small steps to the desired final position prescribed by your orthodontist.


Don't wait - the first appointment is free so why not see if Invisalign®is right for you. After sending precise treatment instructions, Invisalign® uses advanced computer technology to translate these instructions in a sequence of finely calibrated aligners — as few as 12 or as many as 48. Each aligner is worn for about two weeks and only taken out to eat, brush and floss. As you replace each aligner with the next, your teeth will begin to move gradually — week-by-week until the final prescribed alignment is attained. Then you'll be smiling like you never have before!
