Expert care. Very personable and thorough. Takes time to explain procedures and why they're needed. Office is immaculate and the staff very friendly and helpful. I strongly recommend Dr. Cocolis. read more

I've been in the customer service/support industry for 20 years and there are two businesses that I frequently bring up in conversation when giving examples of the best customer service I've received - USAA and Dr. Cocolis's office! I've been a regular for about 2 years now and with each visit, my admiration grows. Not sure if the team is just simply that cohesive and happy or if they've undergone tremendous amounts of training. Regardless, this office is a well-oiled machine and I always look forward to my appointments. If only I could find a doctor's office in our area that matched this level of service! read more

It was very good experience that I had for my implant procedure , very fast and confident

When I needed a first root canal in my life and was anxious and unsure Dr. Cocolis looked at me in a derisive way in response to my questions. He lost my trust at that moment. Sadly had had good experience with him prior to with several fillings that needed to be redone from another dentist. He also upsold my family member on teeth whitening who DID NOT NEED IT. I want to trust my dentist most of all. read more

Best Dentist Best Staff Confidence level for expertise is a level above. They spend more time with you because they are very thorough - every concern is discussed and they go over your X-rays. Provide preventative suggestions ask a lot about f questions. I highly recommend. read more

Dr. Cocolis and his staff are just plain wonderful! I have a lot of anxiety and past trauma about dentists and doctors, and Dr. Cocolis and his dental hygienists (shout out to Annie!) do everything possible to put me at ease with their good humor, delicate touch and latest technology. I had my first filling at age 61 and was really anxious about it. Dr. Cocolis patched up two cavities so expertly and with zero pain. Zip zippity zip, nada pain. He talked me through everything, telling me about each step before he did it. FDR was absolutely correct: the only thing you have to fear is fear itself. Give Dr. Cocolis a call and you will be delighted and amazed with the results! read more

New to the area and am very particular about my dental care. I needed 2 old fillings with cracks replaced, with possibility of crowns. Dr. Cocolis uses cutting edge technology and has a great personality. His credentials and reviews are impressive. Best experience and it was painless. Update: Second filling replaced and it was flawless like the first one. His expert care makes me feel relaxed and confident in his dental care. So happy to have Dr. Cocolis as my dentist! read more

Just had my first ever root canal with Dr. Sanam and it was perfect as she was an absolute pro!! First off, my general dentist in Maryland had told me that tooth #19 needed the procedure. However, after Dr. Sanam's thorough investigation, we found out that it was actually tooth #18 that needed a root canal, which saved me several hundred bucks, tons of pain, and extra trips to the dentist. Prior to the procedure, she made sure to explain step-by-step what she was going to be doing and why she would be doing it. She also did the same during the procedure and made sure to ask how I was doing every few minutes, which helped keep me calm throughout the whole process. Not only is Dr. Sanam a pro at her craft, but she's also the kindest and sweetest person you'll ever meet. All in all, I had an incredible experience and would highly recommend Dr. Sanam and this dental office to everyone. read more

I went here for a routine exam and cleaning. I was informed by the dental hygienist that as part of the exam, they would check the depth of pockets between the teeth and gums. The hygienist lightly stabbed me in the gums (or at least, that's what it felt like) on the upper-right part of my mouth using a sharp instrument. I told her that what she did hurt. She asked if it was discomfort or pain, and I told her it was painful. I allowed her to proceed with the exam and she again stabbed me in the gums, this time more painfully. I told her that she can't proceed with the exam if she is going to cause this amount of pain. She informed me that she has to do this as part of the exam. I told her that she needs to skip this part of the exam if it's going to hurt this much. She told me she would get the dentist and ask him what to do. The dentist (Dr. Cocolis) came in and got right in my face and rudely asked me "what can I do for you today?" I politely asked him not to stab me in the gums. He again, and this time more rudely, asked me "what can I do for you today?" I told him that I don't understand the question. He asked me "why are you here?" I informed him that I'm here for a routine exam and cleaning. He then, rudely, explained that as part of the exam, they have to check for gingivitis by checking the pocket depth of the gums. He started over the exam from the beginning and roughly jabbed instruments into my mouth and painfully pulled my lips apart. He rushed very quickly through the exam and at one point accidentally poked me in the nose with a dental explorer. He then said he was starting the pocket depth exam. I asked him if he can do it without stabbing me in the gums. He said he would try but that the exam is necessary and can be painful. I allowed him to proceed. He then stabbed me in the gums (or that's what it felt like he did) so hard that I almost jumped out of the chair. I pushed his hands out of my mouth and told him to stop, and I then told him that there's a certain level of pain I'm willing to tolerate, but if he can't perform the exam without exceeding this pain level, then I'll find a new dentist. He then rudely told me to leave. I've had the pocket depth exam performed many times at previous dentists, and sometimes it hurts a little but I've never experienced this amount of pain during any dental exam, EVER. I see a dentist every 6 months, my teeth and gums are in good health, and there's no reason it should have hurt at all, let alone this much. Once I informed him that the procedure was causing me pain, Dr. Cocolis did nothing to try to accommodate me or ease the pain. In fact, the third time he tried to do the exam hurt much worse than the first two times. As I type this review (almost 2 hours later), my gums are aching with pain, red, and swollen. Dr. Cocolis, from the start, was unnecessarily rude, aggressive, and confrontational. His behavior was very unprofessional. read more

Literally the best dentist I've ever been to. And I have been to a lot. I was dreading this appointment but it was amazing!! 100% pain free! Precise dentistry. Smart, intelligent. And excellent bed-side manner. He took time to explain procedure both before and after. Answered all of my many questions. Highly recommend. Fabulous and knowledgeable staff a huge plus! read more

Ever love your dentist? No? Then you have to give Dr. C and his team a chance. They'll change your mind. The service is amazing, the professionalism TOPS. From routine cleanings which result in the whitest smile I have had in years to a recent (minor) surgical procedure, I have been impressed every time. You owe it to yourself and anyone you care about. And no, I am not affiliated with the practice in any way. But I refer my friends, take my family and go myself. read more

I'm so glad I did my research before I scheduled my appointment. This dental practice is very professional and Doctor Cocolis is very kind, compassionate and knows his stuff!!!!! I trust him to do a great job and highly recommends him to others. He has never let me down and will check on you to make sure all is well. Thank you Dr. Cocolis and staff. read more

I can't say enough good things about this office in general and Dr. Cocolis in particular. When I first made an appointment it was after having several really bad dental traumas, and seeing a couple people who said that they couldn't help me. One of my main issues was TMJ made complicated by hypermobility and a lot of jaw inflammation from previous problems. Dr. Cocolis was so reassuring and over the course of several months has walked me through a process that has completely allowed my jaw to relax and my bite to be corrected. I was in so much pain for years, and I am finally seeing that pain disappear. I also have a history of being really hard to fully numb for dental procedures, and he very patiently figured out which nerves were still causing me pain. And the procedure itself was the fastest and most precise I have ever experienced! I highly recommend Dr. Cocolis, especially for compassionate care when you have a complicated issue. read more

Dr C is my mom's dentist. I had a long term issue with a molar that no dentist could properly resolve resulting in about 6 years of pain (it took me a while to save up for the proceedures recommended by my dentists I should have done). The basis of the problem was an untreated cavity during childhood followed by that same tooth being cracked when my wisdom teeth came out later. No dentist believed me when I told them it was cracked. They insisted on saving the tooth. They put a crown on it then a couple years later performed a root canal. After the rc my tooth was never 100% but it felt about 70% better until one year later where I could not eat on that side. I went back to my dentist and insisted they remove the tooth. Instead they told me to go see the specialist who did my rc to check it. I went and voiced my concerns. The specialist gave me some options (antibiotic in case there was an infection although he doubted it was that. He told me to stop grinding my teeth and clenching on my jaw which I sometimes do) ultimately he said if I'm still in pain that I would have to come back and he would have to go back in and check the rc. I thanked him for his time and went to get a different opinion. I came to Dr. C and told him my history with my tooth and told him I was done being in pain and asked him to pull it out. He looked at my mouth and realized my bite was off and my original crown was pretty beat up. Like most dentists, he didn't want to remove the tooth at first. He suggested a temporary crown with a proper bite for my mouth. He said if in about 3 weeks I was still not pain free, he would pull my tooth because it was most likely cracked. 3 weeks went by with some relief but still some pain. I wasn't going to pay for another crown only to be back in 2-4 years. I had him remove my tooth. When he inspected my tooth he saw the crack. I cried because finally a dentist listened to me and wasn't solely after my pocket. I was very pleased with Dr. C and his staff. I'm only sad that I found him so close to when I moved out of the area. I'm so happy now and pain free :) read more

I have been with my dentist located in Falls Church since I was a preteen (over 20yrs). He was/is great. But I wanted my family to be under one practice and moving further south (Prince William) it was a hard commute. In the DMV area there are many dentists to choose from. I was referred to Dr. Cocolis and was timid about transferring to another dentist. But again, having my own family and wanting us all to be under one practice, I thought let me give Dr. C a try and I scheduled my daughters first dental appt. She was 4yrs old. From the time we walked in, to the time we said good-bye I have never felt more welcomed and comfortable. My daughter is now 6yrs and I have transferred not only myself, but now my husband to Dr. C. And trying to get my mom too! The ENTIRE STAFF is amazingly friendly, knowledgeable and confident with the level of service provided to each of their patients. I could not be happier taking the leep. :) read more

I've been a patient of Dr C since 2007. He has helped me through TMJ therapy, crowns, etc. He and his staff are kind and understanding of my high anxiety with dental work. I trust my whole family to receive treatment from this office! Somehow, Dr C even gets me to laugh at least once during my visits there. read more

What an amazing experience. Not only is Dr. C the best I've ever seen but his staff is hands down the best at what they do. I have been through alot of dental work over the years and Dr. Cocolis always gives his expert advice on what to tackle next. The hygenist are amazing they actually go the extra mile to do the best possible job.My teeth have never been so clean as when I leave. My Husband is also a guest of Dr.Cocolis Thanks Dr. C Heather and Dave P. read more

I have NEVER had to wait in the waiting room for more than 2 minutes beyond my appointed time. This office runs like a finely tuned Swiss watch. Everyone who works there is super nice and caring. (And I love the 80s music that is always playing!) read more

Dr. Cocolis pulled four teeth on our 8 year old daughter. He was incredibly patient and didn't rush us through the appointment. He explained everything to our daughter and answered all of her questions. He answered all of our questions too! He was efficient, and handled our daughter's concerns amazingly well. His staff was remarkably friendly too. I would absolultely recommend him for grown ups and children alike. read more

Dr. Cocolis and his staff are top notch. My entire family has been going to see Dr. Cocolis for about 8 years and we have all had great treatment throughout the years. My older son used to have an extreme gag reflex and we struggled at another pediatric dentist office every time we went. We changed to Dr. Cocolis and they helped him manage it so that now his trips to the dentist are no longer fearful. The office staff are very caring and make you feel special to be there. read more

Dr. Cocolis is not only a great dentist, but he also takes his time with his patients to explain the procedures and put the patient at ease. His staff at all levels is top notch, both administratively as well as the hygienist (super I might add) who has also been taking care of me and my wife for years. Gene read more

My family and I have been to many different dentists over the years. The staff at this office has been consistently friendly and the waiting has not been an issue. We were pleasantly surprised until over the years (5), we started to notice a trend in having cavities. I have had 2 cavities my entire life and began having regular cavities every visit. One or two at a time. I just figured I was older and that's what happens. However, we also switched my two children here since I was having such a positive experience. After a while the number of cavities detected (all "small") started to become routine for them as well. One child had 4 "small" cavities filled and then was noted to have another 4 at the next visit. Before I had them filled went for a second opinion where we were told this child did not have ANY cavities!!! We immediately switched dentists and have not had a cavity since between all 3 of us. BEWARE read more

I completely agree with allot of what was said in Dr. C's strong reviews. Their presentation, cleanliness and friendliness is very impressive. I have referred a lot of people their way in the past. My biggest issue and reason for a low rating is trust. I have traveled a lot and have had to use many different dentists. My first cavity was found and filled when I was 23 on my first visit to Dr. C. I didn't question it at all. Over the next 3 years at least 4 more cavities were found in his office. I began to question why there was such a dramatic change in the health of my teeth. I had been maintaining my teeth the same as I had for the first 23 years of my life yet now a filling was almost a expectation I had to have for every visit. Suspision was at a peak last year during my final visit to Dr. C's office when yet again I was told I had a cavity. A week later I went to get a second opinion at a new office. They could not find anything even when I pointed to the spot where I was told there was a cavity. I did not tell them of my suspicion. I have gone to the new dentist 2 times and have been cavity free "knock on wood". I really enjoyed Dr. C's office. Everyone was so friendly which makes it harder for me to write this review. I may be paranoid and wrong but I can't help wondering if I was scammed and pitched unnecessary filings for extra cash. I hope I'm wrong but none the less my trust has been withdrawn. read more

My visit was very unsatisfactory. I was intimated and bullied to accept a procedure that I did not want. I wish I could give it a minus star. read more

My family and I have been seeing Peter Cocolis for over 16 years and couldn't be happier. Peter and his staff are not only professional and courteous, but they also employ the very latest in technology available in dentistry. When I first met Dr. C, we lived around the corner from his office in Burke/Springfield. A couple years later, we moved to the western part of the county near Dulles, but still make the drive to Burke, because I cannot imaging trusting anyone else with our dental needs. His beside manner is superb - he is so easy and fun to talk to, and puts you at ease from the very start. I am most impressed with how he works with our two young children - he talks to them, explains what he's doing, and makes a dentist visit actually fun for them, if you can imagine! For a short time I took them to a pediatric dentist closer to home, but after one visit I knew it was worth it to drive 30 minutes to see Dr. Cocolis in stead. Over the years, he has cared for my husband's (nearly perfect) teeth, as well my (very far from perfect) teeth. The emergency number for his office is a cell phone that the doctor answers himself - who else does that?? Highly recommended, by a patient who has had root canals, Invisalign and everything in between with Dr. Cocolis. He is the absolute best in the business! read more

I am not a dentist's dream- just saying. I feel true fear when I have to go to see "the dentist" and really do hate it. Yesterday I went in to have two cavities filled. Before the procedure, I expressed this to him. Dr. Cololis handles rejection of love very well. He is patient and understanding. I still don't like going to the dentist, but Dr. Cololis does everything within his power to make me feel less panicked and has the ability to quell a lot of my anxiety. He is confident and competent. I am not sure he will ever get me to a state in which I love going to see the dentist, but I do love going to see him. Thanks Dr. Cololis for putting up with me. read more

Very professional and considerate staff, they are all sweet and tell you everything that's going on. I would highly recommend this place.

If you need a dentist go to Dr. Cocolis! They are very professional and do an excellent job. Not only that, everyone is very friendly and treats me so well. I can't say enough good things about them. read more
