I find Dr. Cassidy and everyone in his office very capable, professional and nice. I highly recommend Dr. Cassidy as an excellent dentist. He explains things well and does a great job addressing my dental needs. If you are looking for a very good dentist in Alexandria, go see Dr. Cassidy. read more

Dr. Cassidy is a top-notch dentist who genuinely cares about his patients. He's been my dentist for almost 20 years and I have never had a bad experience or questioned his recommendations. His staff also is five-star -- talented, efficient, and personable. Dr. Cassidy closed his office for several months when COVID-19 hit and waited to reopen until he had the necessary equipment and procedures in place to keep his patients safe. I went this week and had to wait in my car until the hygienist came to get me, answer questions about my health, and have my temperature and oxygen levels checked before I could go into a treatment room. My anxiety about going was totally unnecessary. I recommend Dr. Cassidy and consider myself lucky to be his patient. read more

Dr. Cassidy's training and experience highly recommends him as the best dentist in our community to whom I comfortable address dental issues and he professionally helps me. He performs technical skills at a very high level, he loves his patients, and he works with dedication to serve everyone. Looking forward for my next appointment which comes up in few weeks!!! Thank you Dr. Cassidy read more

Wonderful staff, nice facilities and there's something to look at on the ceiling while you're there. Dr. Cassidy is very nice as well but perhaps a bit 'proactive' on getting work done if you need it without really discussing the costs involved. I walked out of there once with whopper of a bill that was much higher than I'd have gotten at my old dentist to the point it'd have been cheaper to travel back to see him for it. To his credit though he reduced the bill later by about 25% when I talked to him about it. It all seems out of caring for your dental health and not greed though. In the end it kind of evens out but it might rub someone the wrong way if you're not ready for it. read more

An excellent dental practice. I am a patient and so is a close relative. Dr. Cassidy is a very good dentist who fully understands the patient's desire to have healthy teeth without painful treatment. I recently had a complicated health problem that did not seem to me to be dental at all. Dr. Cassidy diagnosed it correctly and did the dental portion of the treatment, including follow-up. He gave me a referral to a superb endodontist for that part of the treatment. The staffs of both offices interacted well, and the billing went through without hassles. Dr. Cassidy's hygienists and office staff are also extremely good. This practice has a friendly and productive atmosphere centered on caring for the patient. read more

I recently moved to the West Coast, and one thing I will miss the most about the East Coast is the incredible care I received from Dr. Cassidy and his staff! Everyone on staff is patient, kind, and compassionate. I really feel as though they are looking out for you, whether it be about your teeth or your wallet. I always felt calm and comfortable in the chair, and never felt like I was being taken when it came time to settle the billing. The records department couldn't have been more helpful when it came time to transfer my records. They gladly completed additional paperwork my insurance company required and sent my records to me at no cost. Please try Dr. Cassidy if you are looking for a new dentist! read more

Dr Cassidy and his whole office is amazing! I've been coming here for over 18years and everyone has taken such great care of my teeth, and now for my whole family too. In particular during covid, I have to say the cleanliness and procedures in place are truly top notch. I feel so safe. I would highly recommend this office to anyone looking for a reputable, professional, and friendly dentist! read more

This review is long overdue. About 8 months ago, I had a front crown pop out. You can imagine the horror on my face when I was told that my previous dentist's office was closed that week. No blame on them whatsoever. They were moving offices that week. Their voicemail message suggested to contact Dr. Cassidy "in case of emergency". When I called Dr. Cassidy's office, Joanne at the front desk answered the phone. Joanne is the nicest and most accommodating and compassionate person that I have ever met! She was so helpful and was able to find time in Dr. Cassidy's schedule that day! And just like that, my crown was back in. Dr. Cassidy made me feel like I was a patient of his for years! I had such a great experience and loved Dr. Cassidy and his team so much, that I decided to switch from my previous Dentist, and have been going to Dr. Cassidy ever since. There's such a sense of calm in that office and a friendly, family like atmosphere when you walk through the door. I also have to mention his amazing team. The Hygienist is so gentle and extremely thorough. I highly recommend Dr. Cassidy for all of your dental needs. He's kind, caring, and extremely knowledgeable, a master at his craft! read more

This place feels like a spa when you walk in. Staff are gentle & friendly. Office Manager greets you with a warm smile and is extremely knowledgeable. My cleanings & checkups are drama free! read more

Everyone I know raves about Dr. Cassidy- patients and other professionals in the field. I have to say, I completely understand why! He has a great bedside manner, has a clean and up to date office, the staff are so sweet, and you don't have to wait weeks for an appointment. read more

I started going to Dr. Cassidy when I needed a cleaning in the next few days. His office was able to fit me in quickly. I feel so fortunate I found him because I find him and his whole staff to be completely professional and welcoming. The office is pleasant. The level of communication is excellent. For instance, last time I had my teeth cleaned the hygienist gave me a refresher on best ways to clean my teeth (I had been wearing my enamel away by brushing too hard after eating acidic foods). I completely recommend! read more

I recently had a complicated dental matter that unfortunately Dr. Cassidy missed. Completely. Thankfully, it was caught and addressed before I experienced further tooth and root damage (in fairness, neither of which had anything to do with Dr. Cassidy other than the missed diagnosis). Based on other reviews, it looks like he may be good for some patients, but I would not recommend him for cosmetic dentistry or even complicated general dentistry. read more

I wanted to write and give a shout out to my dentist Dr. Daniel Cassidy. In addition to regularly taking great care of my teeth, he also provided a dental exam for a Colombian orphan who has been staying with us this summer. He heard about her visit and he and one of his wonderful dental hygienists, Claudia, offered to clean, examine and Xray her teeth. Claudia is also from Colombia so she was able to speak to Cami in Spanish and make her feel very comfortable. Cami has not had access to regular dental care in her home country which made this visit very important in establishing a baseline for her future medical care. My family would like to thank Dr. Cassidy and Claudia from the bottom of our hearts for your kindness and generosity! read more

Outstanding dentist. Have been going to him for years. Have recommended him to multiple friends.

VERY expensive if he is not a Network Provider...especially if his staff does not tell you he is Out of your Network until after your $330 teeth cleaning ;(. ( Seriously? $330 to clean teeth?) Bummer. read more

I have been a patient for a number of years and always feel very comfortable and confident in Dr Cassidy's ability to do an excellent job. He recently went above an above. I had a partial crown fall off and he completely redid everything free of charge. I feel that he completely stands behind his work, wants the very best for his patients and does everything in his power to alleviate any concerns or pain you may be experiencing. Would highly recommend! read more
