Zachary Casagrande, DDS

“There is nothing like making a positive change in someone's life. Creating a beautiful smile gives both kids and adults enhanced self-esteem, confidence, and happiness. My team is made up of the best people in orthodontics--over 90 years of total experience! Not only are they all extremely qualified and technically proficient, but each and every one of them brings something unique to the practice, and they love doing what they do. Together, we make great smiles, healthy bites, and have fun doing it!”


A Northern Virginia native, Dr. Casagrande attended Sunrise Valley Elementary School and South Lakes High School in Reston, Virginia. After graduating from James Madison University, he received his Doctor of Dental Surgery degree, magna cum laude, from the Medical College of Virginia (MCV). In addition to his dental degree, Dr. Casagrande also earned a Master of Science and a degree in Orthodontics from the Medical College of Virginia. During his time at MCV, Dr. Casagrande received grants from Pfizer for work on his master’s thesis. He remains part of the Medical College of Virginia as an Assistant Professor in the Department of Orthodontics, teaching residents to become orthodontists.


Dr. Casagrande is highly trained in the latest orthodontic techniques and treatments for pediatric, adolescent, and adult patients including Invisalign, Invisalign Teen, and self-ligating Damon bracket systems that can reduce treatment time and increase patient comfort. He is the only Invisalign Super Elite Provider in Loudoun County and only single-location Super Elite Provider in all of Northern Virginia. He has treated more Invisalign patients than any single-doctor practice in Northern Virginia. This distinction puts Dr. Casagrande amongst the top 1% of Invisalign providers nationwide. Invisalign has chosen him as one of their national speakers. He also has extensive experience with complex cases requiring orthognathic jaw surgery as a member of the VCU Craniofacial/Facial Reconstruction Team. Washingtonian Magazine has once again recognized Dr. Casagrande as one of the DC area’s 2011 top orthodontists as voted on by his peers.
