I consider myself lucky to have been under the care of Dr. Markogiannakis. She is an excellent dentist who is passionate about her work, and if it wasn't for her, I probably would have ground my teeth down to the nerve by now. She was also able to repair and fill the parts I had worn down. Sadly for me, my new insurance doesn't include her in my network. That said, I want to reemphasize that she is a top rate dentist with a top rate team and practice. read more

Extremely unprofessional. Patient care poor. Disrespectful. Dishonest. Frightening experience during two visits.

Moving to a new city and you need a Dentist, Stop! You have now found it, Dr. Markogiannakis, (Dr. Marko) DDS I have never been to a Dentist that looked at each tooth and gave me a clear picture of my dental care. Everyone from the moment, I walked into the office, made me feel comfortable and that my care was in their hands. I am so impressed! It is a well-oiled machine Dental practice. I can check Dentist off my list. My dental cleaning was perfection. read more

Top-notch dentistry! Knowledgeable, highly skilled, well-equipped, efficient, and friendly.

Before I met Dr. Marko I bounced around from dentist to dentist for years. Sometimes I used a referral from a friend or company and sometimes I just searched online. I never truly felt the dentists I had seen were putting my best interest first. It felt as though I was just in an assembly line of customers. It felt as though profit was the main goal and not my well being. This feeling kept me from coming back more than a few times to any of them. But then five years ago I discovered Dr. Marko and it was the total opposite feeling from day one. She has always made me feel like the priority at any given appointment. She is truly a great person and an amazing dentist. In the time I have been a patient of Dr. Marko I have received many treatments as my dental hygiene was not the best. She has performed many cleanings, whitenings, fillings and major work including implant crowns and extractions. Every procedure has been top notch and I am very lucky to have found her. I will be a patient for life. read more

I've been seeing Dr Markogiannakis for several years now, and I'm a huge fan. My first visit was after I hadn't seen a dentist in several years and was having some pain. I have cavity-prone teeth, and she was extremely helpful in breaking things out into a few cavities she thought I should deal with sooner versus other potential cavities that she'd keep an eye on. She did a great job with the fillings I needed, and since then I've been able to stick to regular cleanings and a nightguard. The technicians who do the cleanings are extremely competent, friendly, and take care to make it as comfortable as possible. I've had dentists I dreaded going to in the past, which is part of why I had such a gap before going here. I have no worries before these visits! read more

1. Well-managed, efficient practice. 2. Patients receive a treatment plan with a clear explanation of each proposed component. 3. The treatment plan is executed in stages over time, while adapting it based on new information, all the while explaining the changes and the reasons for them. 4. Skilled. 5. Personable, including staff. read more

Not happy. Insisted having new x-rays when old ones were not old. Had routine care with no complaints. Then Dr. and staff pushed fluoride painting of teeth. I looked it up and that treatment is recommended for kids 5 to 16, and not beyond unless one is a high risk patient with a history of many cavities each ear. At advanced age that does not seem necessary, I'm not age 10, and I have a cavity every 5 years. Fluoride seemed to be a profit center. That brings up an issue of morality and makes one question how much is recommended for any treatment. Prior dentist who is now retired never thought it was wise or necessary. And, the cost was great! I would run in the other direction. It's easy to smile at patients and ingratiate yourself. But that's not why people seek if the care is profit oriented. That's my personal opinion. You can look up the literature on fluoride in adults easily enough. read more

Dr. Markogiannakis's office is a joy to visit. Her staff are very efficient, and obviously chosen for their abilities and their cheerful demeanor. I have had a number of procedures over the years by Dr. Marko, from regular cleanings to permanent fixtures and crowns. I have always felt very well cared for, and appreciate her expertise and genuine concern for my well-being. Highly recommended! read more

After having a very poor experience with my prior dentist, I began a search for a new one. I stumbled upon Dr Marko while doing a search through my insurance company. After much research, I decided to give Dr Marko a chance. My first appointment was a consult. I felt very comfortable, almost as if I was being welcomed into a new family. The entire staff was exceptionally welcoming, and Dr Marko was clearly knowledgeable in her field of expertise. All in all... I knew that this office was a right fit for me! My second appointment was a routine cleaning. Once again, the staff welcomed me with open arms, and treated me as a family member. Dr Marko and her staff are incredibly friendly, and I would highly recommend her services to anyone searching for a new dentist. read more

Dr. Marko and her team are amazing! The office has extra safety precautions in place that made me feel extremely safe visiting during the COVID-19 pandemic. Dr. Marko continuously makes me feel comfortable in the chair and her office and her team are so fun and welcoming! She always provides the most conservative and comprehensive dental care each and every time I come in for a dental visit. The positive energy in the office makes going to the dentist very enjoyable! Dr. Marko is the best dentist in the Washington D.C. area! read more

I am very cautious recommending a DDS as I've had much oral work done over the years. This DDS, Dr. Markogiannakis, is very good. Work I've had done has required from oral hygiene to surgery - she is 10/10 is my book. read more

I normally don't write reviews but I had a terrible experience. Beware! They look like a nice practice from the outside but it took me a while to realize that they were actually crooking me. They kept doing filling on my teeth when I did not have any problems. I got suspicious and got a consultation from another dentist. They checked my XRays and said my teeth were 100 percent okay and I did not need any fillings. Lost my money and time with this practice. Never going there. Also, the dentist is always rushing and never has any time for you. Only things they talk about it is how terrible your teeth are and what expensive treatments they can do for you. There are so many dentists out there who are genuine and would provide you with a pleasant experience. Save your $$$$ and your teeth from this practice! read more

I've been going to Dr. Marko for over 10 years: She's beyond excellent! Her tremendous care for her clients coupled with the most advanced technology allows her to be the best in DC/MD/VA. Amazing Dentist! professional Staff! State of the Art office! Best Dentist in our area. read more

I have had a lot of dentists over the years and too much dental work - cavities, root canals, crowns, implants. Dr. Marko is as good as I've found. She's attentive, comprehensive and personable and has assembled a good staff in a nice office near the Friendship Heights subway stop. She'll help you create a plan and timetable to meet your budget and annual insurance limits. And she can reference other great dentists for more elaborate treatments She's on the younger side but very experienced. So she's a great dentist to choose for the long-term. As a bonus, she also accepts Aetna and other insurance. Many dentists of her high quality do not. read more

Going to the dentist can be stressful to many people. I was lucky enough to have found a practice that always made me feel like I was visiting friends. I was sad when I learned my dentist was retiring as I didn't know what was coming my way. Then enters Dr. Markogiannakis. Dr. Marko recently took over this practice without a hiccup. I get the same welcoming and comfortable feeling as soon as I walk through the door. The staff, some old some new, are all terrific. Dr. Marko has upgraded the practices services and technology. She is easy to talk with and explains everything clearly. The office is renovated, clean and bright. I'm very satisfied with Dr. Marko and her practice and I'm sure you will be as well. read more

Having had several dentists over the years, I can't say enough about Dr. Markogiannakis (aka Dr. Marko) and her entire staff. The entire staff is professional, friendly and caring. Dr. Markogiannakis and the Hygienist (Jamie) take the time to explain procedures and encourage you to ask questions. You don't feel rushed. I highly recommend (and have) Dr. Markogiannakis office practice to anyone without reservation! read more

Went here for the first time today through a referral promotion with my company and I just need to say that she might be the best dentist i've ever gone to. The process of making an appointment was a little rocky as it seems like they may not have a front desk attendant and between making an appt on ZocDoc and then follow up calls for the appointment I received a confirmation for 12:30 while they received it for 1:00. With that being said I'd wait hours to keep using her as my dentist. Her dental hygienist is the sweetest and made the entire process painless and as I was on a tight schedule worked quickly and efficiently while still making sure I got everything I needed. Most hygienist and doctors don't take a ton of time to explain whats going on with your teeth and just tell you to floss more but she took a lot of measures to prevent issues that were starting to occur as I'm getting older and can stop them now instead of being a toothless wonder later. I highly highly recommend her and she has an awesome referral program to get you a free teeth whitening kit if you refer friends or family! read more

Dr. Marko and her practice are wonderful; I could not recommend this dentist more. Dr. Marko is very capable, thorough, and takes time to explain the procedures. Jaime (dental hygienist) and Lisa at the front desk are fantastic. They take top notch care of my teeth and make the experience of going to the dentist positive, with friendliness and good energy. They make it easy to work going to the dentist into my busy schedule because all appointments are convenient and timely. The location is convenient too, in the Barlow building in Friendship Heights. They are great about explaining any questions I have about insurance and billing. I have confidence and rest assured that under Dr. Marko's care my teeth will be healthy for years to come. Wonderful dentist and practice. I give the utmost recommendation! read more

Must be the best dentist in DC -- Dr. Marko was recommended to me by a friend and it's one of these recommendations that you're truly grateful for. I had to have a couple of fillings and a crown done, and it was the perfect experience. The whole treatment (4 sessions) was absolutely pain-free, and I didn't even feel the injections. Dr. Marko explained her every step and even warned me of unpleasant sensations that never actually materialized. Most of the time I didn't even notice Dr. Marko's nimble fingers, and at one moment I nearly dozed off because I was so relaxed. Dr. Marko and her assistant Chanel are a well-oiled team, and it shows that they do enjoy their work. Their positive energy and lighthearted talk is contagious and before you notice it, the session is over and you have to leave. If you're looking for a new dentist, that's the one! read more

Not clear in the way they charge! she is good but because I had to fight each time for big mistakes in my bills, I would not recommend her at all. Not only that, she sent me to many specialists for one tooth!, they are not clear at all. I am about to contact my insurance company! I just arrived home and a 2000$ bill was waiting for me which of course is a mistake... I am soooo mad! last time they charge me for a work that I didn't want... A real mafia! read more
