5 stars

"Greatest Dentist in Herndon. We are a military family and have lived in several states and Dr Jefferies is the best. Gentle knowledgeable and thorough. He also doesn’t try to “upsell” on unnecessary procedures, like other dentists I’ve used."

- Bee H.

"Dr. Jefferies and his staff are excellent! You are greeted warmly as you arrive, and you never wait longer than a few minutes to been seen. Any procedure that you have, is explained, and any questions you have are answered promptly. I am very glad to have found Dr. Jefferies as my family dentist."

- Debbie L.

"Dr Jefferies, the hygienist that did a fab job on cleaning my teeth, AND the front desk gal, Kayla, are phenomenal. I'm a very pain sensitive patient and they've been so accommodating over the years. Kudos!"

- Irene W.

"I've been seeing Dr. Jefferies for over 15 years, and he has always been extremely professional and kind. He is highly skilled, precise, and undoubtedly the best family dentist I've ever had. I consider myself very fortunate to have found and chosen Dr. Jefferies as my family dentist for all these years, and I strongly recommend him to anyone seeking a family dentist."

- Jordan R.

"Dr. Kim was fantastic: from her thorough explanation of my X-Rays, to cleaning my teeth herself, and performing my filling. I didn’t feel a thing during the procedure — because of Dr. Kim’s expertise. She had a great bedside manner as well and put all patients at ease. Best dentist experience I’ve had, especially with their neat technology. 5 stars for sure!"

- M.W.

"Dr. KIm was wonderful, made me so comfortable and took her time. She made sure I was not in pain. She explained all my options and I didn’t feel pressured towards any procedure. She has great bed side manner and truly cares. Best dentist I have visited in a long time."
