Get in TouchDirections
We have a private entrance in the ULINE building on the ground floor facing 3rd Street NE. Street parking is available on 3rd Street and L Street. The ULINE arena also has a parking garage in the back, up Congress St. NE. Once you park, head to the street level exit and look to the left (Northbound) to see our office sign.
Metro:
The NoMa-Gallaudet U metro station (RED line) is one block from the office. From the platform, head to the “M street” exit. Turn left (Eastbound) and walk under the bridge. The REI will be on your right side. Take the first right on 3rd St. NE (Southbound) and you will see our sign on the building.
What To Expect

All patients are asked to arrive 15 minutes prior to their scheduled appointment to allow for insurance verification/presentation, forms completion, and registration. We do not offer a grace period or late courtesy.
The first appointment consists of a meet and greet with dentist and team, comprehensive exam, radiographs, cleaning, and treatment plan presentation. Patients are expected to bring their insurance card and government-issued identification to their initial appointment. Please note that we do not accept the radiographs of other offices; therefore, you may have an out-of-pocket fee, if your insurance carrier determines you are ineligible for new radiographs.
We are also a fluoride-based practice. Fluoride is a natural element proven to prevent cavities, demineralize early cavities, desensitize teeth, and more. All of our products used contain fluoride. You may have an out of pocket expense for fluoride when using insurance to pay for treatment.
Comfortable Amenities
Our modern dental office was designed to create a sense of calm from the second you walk in our front door. In our lobby, you’ll find a fully-stocked wine bar that you are welcome to visit before or after your appointment. We also have TVs in every treatment room that can access Netflix, so you can catch up on your favorite show while our team works on your smile. We also have headphones available to help you tune out the sounds of our dental equipment, which can be especially helpful for patients with dental anxiety. We want your appointments to be not only productive, but very pleasant as well!

Convenient Care When You Need It
Our office opens at 9 a.m. Monday through Thursday to cater to the busy schedules of our patients who would like to schedule early morning appointments before heading to work or school. We also try to offer same-day treatment post-diagnosis whenever possible, so you can receive the care you need right away instead of making a future appointment. Our team offers emergency dental care for situations that cannot wait until your next scheduled visit. If you need to make an emergency dental appointment for a broken tooth or an unbearable toothache, simply give our office a call so we can advise.
