Chase Garris, DDS

Chase Garris, DDS is a native Virginian who grew up in nearby Fauquier County. After high school, he graduated from Virginia Tech and earned his dental degree from VCU School of Dentistry. He and his wife, who is also a dentist, completed year-long dental residencies in Sitka, Alaska before returning to Virginia.

Dr. Garris’s areas of interest within dentistry include general surgical procedures, crowns and bridges, and general restorative work. His plans for continuing education coursework include aesthetics and cosmetic dentistry, as well as complex implant placement and bone grafting.

Donna Greco, DMD

Donna Greco, DMD has been practicing dentistry in Northern Virginia since 2002. Dr. Greco, who is originally from Missouri, received her BA in Fine Art from Transylvania University in Lexington, Kentucky. She continued her studies at University of Kentucky College of Dentistry, where she earned her DMD.

During dental school, Dr. Greco was one of only three dental students selected to complete a year-long Dental Clinical Research Fellowship at the National Institutes of Health in Bethesda, MD, where she studied head and neck development (normally, participants in this program have already earned a DDS, DMD, or related clinical degree). Since graduating dental school, Dr. Greco has continued to refine her skills and expand her practice scope, averaging 100 hours of continuing education per year—more than six times greater than the Virginia Board of Dentistry’s licensure requirement. She has also participated extensively in research at the University of Kentucky and additional clinical training at Louisiana State University facilities in New Orleans and Shreveport.

Dr. Greco has years of experience in providing care for varied dental needs. She practices the full scope of family dentistry including pediatric dentistry, orthodontics, cosmetic dentistry, implant dentistry, and TMJ treatment.

Gio Iuculano, DDS

Dr. Gio Iuculano attended the University of Maryland prior to graduating from the University of Maryland School of Dentistry in 1998. His post-graduate education includes Hornbrook Group Ultimate Occlusion Program, Great Lakes Education Center CEREC Integration, and Dentistry by Design Technology Meets Artistry. Dr. Gio’s most recent post-graduate education professional certifications and specialties include training in: bites in malalignments; problems with TMJs; patients with muscle pains in the head and neck; and advanced airway management and dental solutions for sleep apnea and craniofacial pain. Dr. Gio is most enthusiastic about his work with solutions for sleep apnea. The positive impact his work has made on the lives of his patients and their families keeps Dr. Gio thirsty for as much continuing education as he can possibly fit into his very full patient schedule.

When his patients are asked why they keep coming back to see Dr. Gio, their most frequent answer is, “He gives us an outline of the necessary work in an honest and straightforward manner, and understands that we want to be informed about all aspects of our dental care.”
