Dr. Henry Lee founded this practice and cared for the Olney community for more than four decades. Today his sons, Dr. Alex Lee and Dr. Justin Lee, lead it, and they are welcoming new patients.
Twin Dentistry is a family-run practice on Georgia Avenue, now led by Dr. Alex Lee and Dr. Justin Lee, the sons of its founder. Every family here was new once, and we still welcome each one the same way: with time to talk, a thorough exam, and a team that makes you feel at home.
At your first visit, Dr. Alex or Dr. Justin will learn your dental history, listen to what you would like to change, and explain what they see in plain terms before recommending care. Their approach is preventive: they would rather catch something small early than treat something larger later.
We see patients of every age, so parents and children can be cared for in the same place.
If it has been a while since your last visit, or you are new to Olney, a short phone call is all it takes to get started.

“Our family has been coming to Dr. Lee’s practice for 12 years, and it’s always a great experience. The staff is professional and courteous, and Dr. Lee’s sons who have now taken over the practice are both excellent dentists.”Andrew Marra Google review

Between them, they have worked chairside and at the front desk here, so they understand every part of a visit, not only the time spent in the dental chair.
