I've been going to Dr J since clock tower days. That is literally forever ago and I still go to him. He is absolutely amazing! Hands down one of the best people to work on your teeth with his beautiful mouth full of pearly whites..hehe. You wont regret going to see him and an added bonus is the office staff. They are amazing, respectful, kind and sweet🙏
We love Dr. Mark. We have been seeing Dr. Jeffries for 10 years as a family. His fees are reasonable, he is the gentlest dentist, and we are always able to get in with emergencies. His front desk staff are kind and incredible. We will stay with them as long as we are here in the area
Dr.Jefferies and his staff are extremely professional and kindhearted. Very gentle and they do amazing work. Words cannot express how great they are. Truly the best at what they do in the herndon area.
Dr. Jefferies is amazing and his whole staff makes me feel like family 💗💕 I will always see him. It’s hard to find a trust worthy dentist and him and his whole staff have earned my trust
Pleasant, professional service and care. Everyone is wonderful! Thank you for being my Dentist! 😊

Dr. Jeffries' office sent a few friendly reminders about my appt, and easily changed my appt time upon my request. I was then seen within 5 minutes of arriving for my scheduled appt. The hygienist was welcoming, friendly, and gentle/attentive to my concerns. I was able to see Dr. Jeffries pretty quickly, and he even helped remove an old permanent (broken) retainer from my teeth, even though this wasn't a scheduled request. I usually only…

So pleased with the care I received, from the receptionist, check in paperwork etc, Amber the hygienist was outstanding, friendly, gentle, professional. Dr Jefferies took time to explain his conservative approach, and really spent time with his exam, and did not run out of the room to the next patient. I'm thrilled that we have found a great dental office.

Appt was quick to get in and out. Lynn the Dental Hygenist was attentive to my fears of sensitivity, gentle at cleaning, and just plain fun to have. Dr. Jeffries was quick but to the point. The whole office makes these check-ups a breeze!

Everyone on the Staff at this dental practice is a true professional when it comes to their technical expertise, but perhaps more importantly to me at least, they are truly nice and friendly folks you like being around. When you say "family" practice - that is the practice of Dr. Mark Jefferies - WE are all "family." I'd recommend these fine folks to anyone looking for a caring and professional dental care staff. They are…

I had been to a few dentists before coming to Dr Jeffires! My experience yesterday was just superb!!! I felt very comfortable and everything was explained to me very well. I was given the opportunity to ask questions! Not sure why it took me this long to find him!!!! But as the saying goes, better late than never!!!
