PATIENT REVIEWS

Smiles of Chevy Chase make going to the dentist a pleasure.  The office is well laid out and attractively decorated.  Wait times ae minimal.  The staff is very helpful and friendly. Dr. Markos is the best: clearly explains work needed and options; I’m always pleased the work done; she is an excellent dentist and has a welcoming engaged rapport with patients.

Dr. Marko and her staff are always very professional. In addition, the office always is clean and it gives me confidence that the tools used are sanitary. Furthermore, when a procedure is performed I have on occasion almost fell asleep or I am very relaxed. Which dispels any notion that dentistry is stressful. Dr. Marko has made sure that I have not lost any teeth and for that I am grateful.

Efficient, forthright and clearly invested in patient care and wellbeing as well as taking proactive steps to support long-term dental health. The doctor’s services are expensive, but standard for the area and level of service. I received a much more comprehensive diagnosis of my current dental concerns than from my previous dentist. As a result, I feel much more confident in my ability to avoid serious issues developing in the future.

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!

Smiles of Chevy Chase headed by Dr. Markogiannakis is the most professional and efficient dentist office I have ever been in. Her and her staff do excellent work and they really care about their patients, and I recommend them highly. In addition, it is the cleanest and most sanitary dentist office I have ever been in.

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.

Dr Marko is as good as it gets. I have been a patient of hers for 2 years now and I highly recommend her to all my friends and family. Her approach to dentistry is unique in that she takes her time with each patient who sits in her chair. She has completed a couple fillings and crowns for me – all pain free (I actually fell asleep through the procedure!). She is very caring, extremely gentle and explains everything in a way I can understand it. By far the best dentist in DC!

I returned to Dr. Markogiannakis after a five-year hiatus due to my husband’s health condition. My experience at Smiles of Chevy Chase on September 7th was excellent. Katia, the hygienist, was the absolutely best I have had in the past 20 years. Sue, the Assistant, is such a nice person and prepares a very conscientious x-rays report for Dr. Marko to evaluate my status. The two ladies who take care of administration are very careful in explaining exactly what is being sent to the insurance in their Statement sent to my insurance and they gave me a copy for ready reference. Then there is Dr. Marko, she is so personable, always very nice, and highly professional. I don’t hesitate to recommend her highly!! She and her group are nothing but the best!

Dr. Marko is the best dentist I’ve ever had in my 60 years. She is brilliant, extremely up to date on new research, conservative in her care, honest, gentle, and incredibly skilled at her work. She is compassionate and a great listener as well. She treats her patients with an incredible amount of respect so I actually enjoy going to the dentist! She has a holistic problem solving approach that allows her to figure things out before other specialists do. I recommend her without any reservations at all. I would never see another dentist.

The cleanest, most professional, the best and latest technology, the friendliness of the staff and doctors is incredible, always on time and by far the best dentistry in all the DC Metro area. I have searched to find a dentist office that meets all my families needs and this is it! If you are in need of an extremely experienced and up to date dental office, look no further. Dr. Marko is wonderful with the whole family! Always keeping up with the best care for our family. I highly recommend this place!

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!

I recently got a cavity filled by Dr. Marko and was pleasantly surprised to find it a quick and relatively painless experience. She explained the treatment plan to me well, answered my questions and made sure I was comfortable the whole time. I also have appreciated the extra safety measures they have put in place for COVID.

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.

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!

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.

First time here and was awesome. I arrived , signed paper work and right after I was done they took me back. They took 5 minutes to check my teeth and I waited 3 minutes before the doctor came in and she was clear. They were able to schedule a follow up appointment in a short manner. There was a lot of people there too yet they were fast and the communication and friendliness was awesome. Highly highly recommend!

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!

Dr Marko and team are simply the best. Starting with the dentistry itself (the reason why you go to a dentist), Dr Marko and her staff are A+. Highly skilled, communicative and always demonstrating great care for you as a patient. Sparkling office, state-of-the-art equipment, friendly and helpful staff, front to back. And things always seem to be running on time. Thank you Smiles of Chevy Chase.

Dr. Marko is a great dentist, very professional and keeps upto date on the latest techniques and procedures. Her office is extremely clean and her staff are there to help you in any way they can. I needed a lot of restoration and implants, I feel great and look so much better. I wouldn’t hesitate to send anyone to see her for consultation.

Dr Marko’s office is exemplary! They treat all their patients with the uttermost respect and professionalism! Dr Marko is friendly in her manner and doesn’t leave patients wondering about what they are doing! She is the person I trust with my smile! Her staff follow closely in her footsteps! I recommend Dr Marko’s practise highly for all your dental needs!!!

She was amazing! The visit was wonderful from start to finish. I get a little bit of anxiety when it comes to cleanings and the hygienist was kind and reassuring throughout. I’ve already recommended Dr. Markogiannakis to several of my friends. I’m happy to finally find a dentist that I feel comfortable with and trust in DC.

The cleanest, most professional, the best and latest technology, the friendliness of the staff and doctors is incredible, always on time and by far the best dentistry in all the DC Metro area. I have searched to find a dentist office that meets all my families needs and this is it! If you are in need of an extremely experienced and up to date dental office, look no further. Dr. Marko is wonderful with the whole family! Always keeping up with the best care for our family. I highly recommend this place!

Dr. Marko was very professional and gave me the most thorough initial dental examination. She made me feel very comfortable by explaining the procedure and what exactly it entailed in a vocabulary that I could understand. Overall, it was a great experience, both pain-free and quick. The office staff was very friendly and the overall cost was much less than expected.I am actually looking forward to my next vist with Dr. Marko!

Dr Marko is VERY cool and by far the BEST dentist I have ever met. She worked on my tooth a few months ago and I was really afraid of getting the injection. I could not believe she gave me the injection and I did NOT even realize it. My filling turned out beautiful and the whole experience was quick, easy and pain free. Her assistants made my appointment comforting and relaxing as well. They were very personable and most of all, Dr Marko and her assistants make a great team.

I recently scheduled a new client appointment with Dr. Marko for x-rays, a cleaning, and assessment of dental health. Wow, best dental visit I have ever experienced! The front desk staff and hygienist were friendly. My appointment started on time. Most importantly, the gentle, pain-free, anxiety-free, and thorough dental examination/cleaning performed by Dr. Marko was remarkable. I have never had such a thorough exam. In addition time was spent with me to discuss my dental health and to provide suggestions. Gentle, thorough, superb!

I have to admit, I am NOT a very good dental patient. I am probably one of those people who the dentist and their staff are not that happy to see. It’s mostly because I’m scared. I got Dr. Marko’s name from a friend and she told me it would fine. I hadn’t been to the dentist in a few years so I KNEW I had a lot that had to be done. Everything about the appointment was NOT what I expected. I expected to be scolded for being neglectful (which always happens when I’ve gone before). That didn’t happen. I expected to be told about how many $$$$s I needed in treatment and THAT didn’t happen. Yes I needed a few small fillings, and yes I did need a cap, and yes my gums needed some work, but it was nowhere what I expected. She explained everything. She cleaned my teeth – a first for me to have the dentist clean my teeth, and while she said she doesn’t do it very often, she felt, that because of my nervousness (which she picked up on immediately), that it would be a good way for her to get to know me and for me to get to know her. The fillings were a piece of cake. I didn’t feel the injection AT ALL. She talked me through the whole thing, and when it came time for the cap, even that was easy. I wish I had more space to rave about her

I have been visiting Smiles of Chevy Chase since the beginning and I continue to be a satisfied customer. The professionalism from each associate in their office never ceases to amaze me. Dr. Marko is a superior leader to her staff and a delight to work with. I highly recommend this specialized dental practice to anyone in the DMV looking for esteemed, professional care in a safe, personalized environment.

Dr Markogiannakas and all her staff are outstandingly competent and cordial. Dr “Marko” always recommends the most conservative and least invasive and least expensive treatment consistent with maintaining your dental health for the long term. She is the best general dentist I have ever had and I highly recommend her.

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.

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!

My dentist retired and so I used Zocdoc to find a new one. Basically to summarize my first appointment, it was like going from a flip-phone to a smart phone! Dr. “Marko” is up to date on the latest equipment and preventive and care strategies. I knew there were some issues with a few of my teeth and she not only identified them but explained what caused them (who knew clenching makes cracks). The X-ray and photographs of EACH tooth that were shared made the fact that while I will need quite a lot of follow up (I hadn’t been to the dentist in 3 years) it will ensure that I don’t have future problems and I could SEE and understand WHY it is necessary.

I’ve been seeing Dr. Marko and her amazing team for 3 years now. I did my research when it came time to finding a new dentist after moving to DC, growing up in a dentist office caused me to have high standards. (And come on who actually enjoys the dentist?!) Well they blew all my expectations out of the park. They’re professional, thorough, informative, caring and very friendly. They always take the time to go above and beyond- even when I gave them the hardest time about finding the right material for my night-guard. Everyone (except me) had patience and reassurance through the whole process. They make every appointment a pleasant experience!

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.

I was delighted to see that the Dental office was clean and tidy . Dr. Despina M Markogiannakis ,DDS. and her dental staff were all following the COVID 19 guidelines , so I felt safe. Dr. Markogiannakis and her staff were all very professional , knowledgeable, kind and friendly . Dr. Marko explained everything to me in lay mans terms so I could understand what she was telling me about my teeth. Prior to leaving my appointment she had a treatment plan in place, so you knew what to expect at the next visit . Her dental hygienist was exceptional and was kind . I. recommend that everyone go to Dr Marco, because it was the best experience I’ve ever had at a dental office Eleni Paras RN
