Patient Reviews

"Dr Claustro is amazing. She’s hands down the best dentist I’ve been to. She’s conservative in her methods and applies practical guidance and education on treatments."

"Dr Claustro and her team keep me coming back because of her and her awesome team. Always a great experience."

"I never write reviews but I had to for this - absolutely amazing experience. Who knew a dentist could also change the way your face looks??? I have tried MANY different face treatments for melasma and aging, and I have never seen results like I did with Dr. Claustro. The Opus Plasma did wonders to diminish wrinkles and tighten my skin, with no downtime at all. I coupled my treatment with the Resurfacing treatment and just wow. Anyone that actually has melasma knows that it is never going to go away, but I have not seen anything diminish it's appearance like this and I have tried EVERYTHING. Add in the amazing staff and Dr. Claustro herself, just top notch. Run don't walk to try these treatments! You will thank me!"

"One of them best Dentist that I have ever had, great staff and a wonderful office. Joanna is very skilled, knowledgeable and compassionate. She cares about her patients and is always working in your best interest."

"Always great to see Dr Claustro and I had my best cleaning appointment ever with Maren!"

"Without a doubt this was the best dental experience I've ever had."

"I can’t believe it’s taken me this long to write a review for this wonderful office that I rave about to everyone looking for a new dentist. I moved out of state for school and still scheduled my dental appointments here during my breaks because I refused to see anyone else. My dental anxiety was so bad that I avoided going to any dentist for over 10 years. Within the first 15 minutes of meeting Dr. Claustro I felt heard, understood, and assured that this experience would be as smooth as possible. You can tell immediately that Dr. Claustro genuinely cares about her patients and wants them to have the best experience. The entire staff is so kind and welcoming, and the atmosphere of the office itself feels like a spa! Megan is my usual dental hygienist and does a thorough yet gentle job with my cleanings. She’s an absolute sweetheart who empathized with my anxiety and made me feel as comfortable as possible. I never thought I’d look forward to going to the dentist in my life, but now I’m obsessed with my oral hygiene thanks to this office. I am so grateful to the entire team for my amazing experience!"

"Dr. Claustro and her staff are phenomenal. I have had such a great experience here after leaving a practice that was not run well. I will recommend her to everyone I know!"

"Outstanding service and stellar staff!!!"

"Always a wonderful experience with Dr Claustro and her associates! Megan is an awesome assistant! Thank you!"

"Another top notch experience at Dr. Claustro’s! Michelle is an awesome dental hygienist and the staff are wonderful! Haven’t enjoyed going to the dentist this much since I was a kid!"

"I travel over 40 minutes to go to this office because their practice is one of the best that I’ve been a patient of. The office is easy to get to, in a lovely building with plenty of parking. Inside it’s extremely clean and modern, well staffed by knowledgeable and friendly assistants (Dina is the best!). They really want to keep their patients healthy. The office has the latest technology which makes for quick diagnosis to issues. Fast cleanings and phenomenally good preventative care (saving you money and sparing your dental health). You wont be left waiting here. Time is a constant struggle for me, and as I said up top, i travel 40 minutes because the care they provide and the consistency of their work saves me in the long run."

"What a wonderful first time visit, both for my 6 year old son and for me! They weren't rushed, took their time, and made everything look and feel easy. My son is often nervous about new providers, but they were so great, so kind, and so gentle just naturally. The atmosphere was lovely, peaceful, and welcoming. My son honed in on a couple really cute pictures he saw of the hygienist's cats and dogs positioned right at kid level (so thoughtful to put them there). He had a great visit, wasn't concerned when they used the normal tools (for him it was a first time with the spinning polisher etc). I was so proud of him, but also so grateful to have found this practice thanks to a glowing recommendation from another mom friend ;-). I am returning to them for invisalign for myself, something I've wanted to do for years, and very excited!"

"After searching high and low for the perfect dentist office I have found it! I had the pleasure of having Dr. Agarwal as my dentist and she is absolutely amazing. She is so caring and attentive.She is personable and makes you feel like family.The staff is AWESOME! They operate with some of the newest technology and they are great at what they do. The office is warm and inviting with a cozy feel. I had to be numbed recently for a filling.…I did not even feel it. I love visiting the dentist, but these ladies made it so much better. This office runs like a well oiled machine."

"Love this place and this team! Michelle did an outstanding job on my teeth. Gently cleaning and encouraging me to get back on track. Dr Agarwal is kind and knowledgeable. I won’t go anywhere else!"

"Great practice! The office is run like a well choreographed dance with very good communication. Audrey at the front desk is very good at what she does. Michelle, the hygienist is also excellent with the teeth cleaning and doesn't hurt me 😁..Dina (sp?) Does an excellent job keeping me calm with her gentle approach...and Dr Claustro formulated a master plan for my husband and in what we needed to have done. She is sweet, professional, caring and we are grateful we found her. Look no more"

"Dr. Claustro and her entire team treat my whole family. I no longer completely dread going to the dentist, I know she and her team will be open and honest with me, good news or bad, and they work very hard to make sure I am comfortable and understand everything. My entire dental and overall health has improved under Dr. Claustro's careful care of treating the root cause, not just the teeth. Dr. Claustro takes the whole patient into consideration with her care and treatment, something very very few dentists and professionals do these days!"

"Best Dentist in town , they always make feel at home when you walk in through out the visit. Would highly recommend."

"The customer service and the professionalism are of the highest level and would recommend this consult to anyone in need of their assistance. I am happy with the progress of my Invisalign treatment."

"Every engagement with staff was extremely professional and friendly. Dr. Claustro exemplifies what a caring doctor should be. There is no judgment, just education and information for the patient. My family and I are very happy with the care she and her staff have given us. Highly recommend!"

"Dr. Claustro is the best! My kids left saying they love the dentist. Thank you for great care!"

"I love this office, they are very accommodating and honest. The hygienist was very thorough and skilled. Dr. Claustro is very welcoming and runs a beautiful operation."

"Great experience for the whole family. I, the husband, and the kiddo has a wonderful experience today. Calming environment. Talented and knowledgeable staff. Feel safe entrusting the care of my family with this team. Looking forward to more confident smiles. Can’t wait for our next set of appointments! Momma is looking for to some me time with aesthetics as well."

"So happy to have an awesome dentist - best practice I’ve ever been to in Loudoun."

"Whenever I visit Joanna Claustro DMD for my cleanings and all my needs, I feel I'm surrounding by professionals that she has staffed. Everyone is very kind and most importantly my teeth feel like silk after Michelle has completed my cleanings. They also monitor my more challanging needs and only refer me to the best doctors for my paticular needs. I of course have to mention Audrey at the front office. She is the gateway to Joanna's business and if success has anything to do with excellent and polite communications with the customers, then J.C. DMD is going continue to be successful if not more.

"Sitting in parking lot outside Dr. Claustro's immaculate and efficient dental practice. I have been a patient for years (believe she was just starting out and has grown so much - for the better - over the years, and my teeth have gotten so much better too). Dr Claustro and her staff - a shout out to her dental hygienist Michelle - the BEST. As a believer that problems are best prevented than dealt with I have worked with Dr Claustro to maintain my valuable teeth while I age. At 63 I consider my work with Dr Claustro a great investment. And to top it off she is friendly and pleasant. GO."

"Wonderful, caring staff who are not only super skilled in their field, but also take the time to ask how you are and remember things going on in your life. Highly recommend!"

"Dr. Claustro, Aubrey, and the hygienists were amazing! You can feel that the warm, family friendly, welcoming environment my family and I enjoyed is who they are. This is only matched by the high quality care, attention to detail and professionalism I experienced. You can tell they care about each person who comes through the door from her youngest patients on up. I would highly recommend the whole family giving this dentists office a try. You will be glad you did."

"Got down to the cause of a problem I was having. Very good experience overall. As usual."
