Being afraid of the dentist, for me, is an understatement as I am almost 30 years old. I legitimately came into my first appointment with Holy City Dentistry terrified of the worst possible scenarios. To be perfectly honest, I hadn’t had anything other than a cleaning done in 5 years, so I was absolutely shaking thinking about what could be wrong. They took amazing care of me, walked me through each process/step, and set up a reasonable treatment plan for what needed to be done. The lovely ladies at Holy City are caring, genuine, and want nothing more than the best for you. I am still afraid of the dentist, but I’ll definitely go back!!

Best dental experience I’ve had. All of the staff I had any contact with from making an appointment to when I left the office are organized, accommodating, and warm. My hygienist was incredible and it was a anxiety and pain free experience. I am actually excited to go back! Dr. Castle has really created an incredible atmosphere at this practice. I watched Gilmore girls while getting a cleaning — and they were super transparent about pricing and everything!

The experience was about really great people here that provided a thorough exam, cleaning, and treatment plan. I love the Dr’s honest approach of a comprehensive treatment plan that wasn’t built to pad corporate dentistry pockets. She gave me focus areas of priority and things we can watch for over-time. I was well-cared for and feel confident in the plan. The hygienist is skilled with a light touch. Nothing hurt. Nothing was scary. She is also sweet and kind. The front office specialist was efficient and super friendly. More than that, she was really nice with each interaction. She was an actual-nice kind of person, not the fake-nice kind of person. The kids corner in the lobby was great. So is the wall of wonders for kids as you pass to the patient rooms. The office is sleek and fresh. The patient dental chair was comfortable. There is a tv on the wall of the room, but even better, there’s a huge one on the ceiling. I don’t have dentist phobia’s so didn’t feel I needed Netflix…. then, I watched a show anyways. That was great. Pick a show and watch it.

Took my 3 year old daughter to Holy City Dentistry for the first time today. Our experience was top notch from start to finish. The Hygienst took the time to explain the whole process and get my daughter involved and excited about her dental health. Dr. Castles is knowledgeable and her professionalism is just what we have been looking for on James island in a dental practice. I highly recommend for young families! Thank you Holy City!! My three year flossed her teeth by herself tonight!

11/10! Dr. Castles and her staff are awesome – knowledgeable, friendly, and super efficient. They explained everything thoroughly and made sure I was comfortable during the appointment. The office is extremely clean and is designed really well. Super nice touch to have a TV on the ceiling so when you’re laying back in the dentist chair, you can watch Netflix. HUGE fan!

Highly recommend! I have dental anxiety and everyone there was so sweet and understanding. Everything was explained to me before it was done and I was made to feel comfortable and left with no questions unanswered. They took their time with me and I didn’t feel rushed or like an inconvenience or an annoyance. Also, office is very clean and paperwork was easily done online at my convenience before my appointment.

Dr. Greenfield has done work on me and she was so empathetic that my mouth is very small. It makes for difficult dental work and she was great! I have been waiting for her to open her practice. I live in Summerville and I will be going to her. Our so. Will be too!

This is hands-down the best dentist I’ve ever been to. The staff is super caring and down to earth, and the detail that goes into each appointment is like nothing I’ve seen before! They were so diligent with what I needed done to my teeth and explained everything that was happening; they even went out of their way to take pictures of each individual tooth to examine them with me. Dr. Castles has such delicate hands and made what had the potential to be painful, a wonderful experience. OH and the office is so beautiful!

The entire staff at Holy City Dentistry are all so very nice, professional and caring! They are truly incredible and make you feel at ease your entire visit! Dr. Castles goes above and beyond to make sure you receive the proper care with the highest level of comfort possible. They truly make you feel relaxed and taken care of from start to finish! With the comfortable setting and super friendly staff I will never be going else where! I give them the highest rating and recommend them indubitably!

]This is the nicest dentist office I’ve been to. It’s clear that they really care about your comfort with two TVs (one on the ceiling and one on the wall) in the rooms to keep you distracted if you’re anxious about dental work, offering you a cozy blanket, and just being super friendly. The appointment process and paperwork through the app are super easy too. I had a great experience here and highly recommend it!

Holy City Dentistry strives to ensure comfort and a stress free appointment. They are patient, kind and add lots of little things to make your experience better, from a massage dental chair, to tv’s with your choice of show! If you are a nervous Nelly or a nervous Ned, this is the place for you.

I put off going to the dentist for years out of lack of insurance and money but when I was finally able to get the repairs my teeth needed, Dr. Castles and her entire staff were great from start to finish. As a person who legitimately feared going to the dentist I can vouch, they do great work and make you feel comfortable, respected and welcome. I will be going to Holy City Dentistry from now on and definitely recommend to anybody in the area. Thank you so much for everything, I’m super grateful to y’all!!!

I am really enjoying my experience with Holy City Dentistry. I am in the process of having a dental crown down with them, and I have found Dr. Castles and her team to be top notch. They are professional and on-point, and they’re also very kind and comforting, which is important to me as I do not particularly enjoy having dental work done. Their office is clean, modern and airy, and I very much appreciate that all their forms/paperwork can be done online on my phone. Highly recommended.

Absolutely the BEST dental experience we’ve ever had! We are new to the area and we were looking for a dentist. We are so pleased with how meticulous and caring the staff and Dr. Castles were. Everything from the environment to the individualized care given to both of us was wonderful! The reception area is CLEAN and accommodates patients of all ages. The game console for the kiddos and the play area for the little ones is very clean and inviting. It’s obvious that Dr. Castles has gone to great lengths to ensure that ALL of her patients feel comfortable and relaxed as soon as they walk through the door. The dental cleaning and exam were pain-free. She is so gentle and meticulous in her work! This is the place to go if you have any anxiety about visiting dentists! She is wonderful! We can’t recommend Holy City Dentistry enough!

If you want to go to the BEST dentist in Charleston, go to Dr. Castles at Holy City Dentistry. I have been her patient for 2 years and from my first visit, I knew she was in a league of her own. I have had dental issues since childhood and have been to many, many local dentists. She is by far the most kind, honest, positive, educated and dedicated dentist I have ever experienced. From basic dental maintenance to dental restoration, which I am having done now, she is the only one I would go to. She is a meticulous master of her profession and sincerely cares about her patients and her wonderful staff.

Five stars for a great experience! Staff is welcoming and friendly, and questions and concerns are taken seriously and directly addressed. Exam was thorough and efficient without the feeling of being rushed in and out. I really appreciated the preventative recommendations made and willingness to help with navigating insurance and being upfront with estimated costs. I enjoyed the online scheduling and paperwork prior to first visit which made the new patient process a breeze. Dr. Castle seems very knowledgeable, personable, and great at clearly communicating future plan of care.

I have been to several different dentists over the past two years. I have terrible anxiety and I’ve been so uncomfortable with them that I have just kept the broken teeth instead of getting the surgery. Holy City Dentistry is a completely different place! I felt welcomed from the time I made the appointment, to the time I walked out the door! They are all very nice and Dr. Castles is gentle and definitely cares!! The whole experience is for you to feel completely comfortable and it was really great to see that in a medical setting. I HIGHLY recommend Dr. Castles and Holy City Dentistry to anyone! Especially if you have an anxiety disorder as I do. I have a referral for an oral surgeon and I don’t have any anxiety about it because I feel like if they are recommending them, I’m definitely in good hands.

I had a wonderful experience at Holy City Dentistry. Dr. Castles was fantastic and very friendly. She was thorough and explained all procedures. Rachel, the receptionist, was very friendly and accommodating with getting my appointment set and paperwork completed on line. Anyone looking for a wonderful dental experience should give Dr. Castles a try. You will be happy with your choice! Dr. Castles performs all of the services herself and sees one patient at a time to insure a safe, secure environment. Thanks Holy City Dentistry office for making my visit a great experience! I encourage you to give them a try.

I was very stressed going back for a dental appointment, it had been over two years. Everyone was wonderful and I was at ease almost immediately after being greeted by the receptionist. She was very welcoming, the office manager came out to say hello, also. All of this helped ease my stress. The hygienist was calming, knowledgeable, and friendly all while maintaining professionalism. I have been to many dentist but this hygienist is one of the best. The dentist was beyond wonderful as well! This was a positive experience and I feel as if my dental health is in great hands!

My experience was really amazing! Dr Castles entire staff were super friendly and very professional! Gaby at the front desk was able to work me in around my hectic schedule. The hygienist, Lael, was the kindest person I’ve ever met and did a crazy good job on my cleaning!! My teeth are sparkling!! Dr Castles made my experience memorable and pain free 🙂 I’ve always had a bit of anxiety about dentist visits. This time, I was having so much fun I forgot that I was at the dentist. I’ll be a member for life! Oh and it’s the nicest dentist office! If you want AMAZING service by outstanding people, this is the place for you! And they love dogs!! 🙂

I had a wonderful experience with Dr. Castles and her team! I was very anxious about my appointment, and they were extremely kind, reassuring, and thorough. They did a great job and made sure I was comfortable the whole time. I was so relieved, and am so thankful to have such a great dentist! I definitely recommend Holy City Dentistry!

We had the BEST experience at my daughter’s very first dental appointment! From the open communication post-scheduling from Rachel, easy electronic forms prior to the visit, and quick check-in process for our arrival. Dr. Castles and her team were so kind and patient with my daughter. They also answered my tons of questions and prepared us for what to expect as she gets older. The facility is gorgeous and very thoughtful, not your regular sterile office! Dr. Castles seems invested in her younger patients as she offers a play space, toy dispensers and more. Everyone was so friendly, we look forward to them taking care of Olive’s teeth for years to come!

I recently moved to Charleston and needed a new dentist. I came across Holy City Dentistry and I’m so glad I made an appointment. This was the most thorough dental appointment I have had. Before my visit, I filled out online intake forms and when I went in for my visit, the staff was prepared to talk with me about my concerns. Additionally, my hygienist was receptive to my sensitivities during the cleaning and took action to make my experience in the chair more comfortable, which I really appreciated, since most previous dentists I have been to haven’t taken this precaution. When Dr. Castles came in and talked with me about my treatment plan, she explained everything and showed me what she was talking about using my x-rays and photos. Now I have a dental treatment plan that I feel good about! I highly recommend Holy City Dentistry and Dr. Castles to anyone looking to switch their dentist, new to the area, or seeking treatment for a specific concern!

Amazing experience at Holy City Dentistry. Both my husband and I have dental anxiety and they did everything possible to alleviate any stress. From puppies to Netflix, they worked with me to ease any anxiety and continually checked on me during my cleaning. Everyone is so sweet and treats you like a lifelong friend. Would highly recommend, best visit I have had.

Dr. Greenfield is the best dentist I’ve ever been to. She is so compassionate and great at explaining necessary details. She even reshaped my front teeth upon request before our wedding so they’d look better for photos! Highly recommend!!

I never leave reviews about any doctors, but this was the best medical experience. I love that the new patient questionnaire asked your preferences for the room and actually did what you asked. The decor is very inviting and cozy. There is even a tv on the ceiling so you aren’t just staring at lights and the ceiling while they work. The staff walked through all parts of the process, answered questions, and even showed my pictures and X-rays as they talked through things. Big plus to being an all female staff as well!!!! One of my sorority sisters recommended Dr. Castle and I was thoroughly impressed.

Not only did I have the privilege to work alongside Dr. Greenfield for a few years , I also had her work on my teeth as well (see picture of crown impression). Dr. Greenfield does top notch work and you will always leave knowing you had received the best care. She is thorough and dedicated to detail. Having her as your dentist is something you shouldn’t need to think twice about. You will always be greeted with her smiling face and bubbly personality.

Took my 2 year old son to Holy City Dentistry for his first-ever dentist check-up. He was a bit shy and scared to be in a new place, but the staff was wonderful and made him feel very safe and comfortable. Everyone was very friendly! The entire experience from the first call to leaving the appointment was easy.

Dr. Castles is an extremely competent, caring and talented dentist. Her team at Holy City is also fantastic. One can tell Dr Castles and the entire team are very passionate about the work they do. I couldn`t be happier with the quality of work Dr. Castles did on my teeth. She was able to perfectly diagnose and fix a few fillings that had been very poorly done by Dr. Patrick Easton at the Rigby Office in Midvale, Utah (city where I lived before). Other dentists in Charleston said I would need to do a root canal procedure, but Dr. Castle was spot on to diagnose and recommend an alternative treatment to save my teeth, make them healthy again and improve the pain and sensitivity. Her assistant Kaitlin is also very competent, caring and accommodating. Holy City Dentist Team went above and beyond to make sure I would get the right treatment and to fit me into the schedule as soon as possible because I was in pain. I love that Dr. Castles discussed the step by step of the treatment, executed it very well, took pictures throughout the process and followed up to see if there were any issues. A big thank you for everyone. Daniela Petu

Holy City Dentistry has to be the best Dentist i have ever been to. It all started when i called around 12:00 pm mid day. Most places were packed and couldn’t even think to fit me in. I was in a 10/10 pain with a swollen face and bleeding gums. The front desk asked me a few questions and seemed generally worried when i told them about what i had going on. I set up an appointment for the next day around 12:30 pm, that seemed forever away with the pain i was in. Than at 3:00 i received a call asking me to come in and they would do everything they could to help me out that day! When i showed up at 5:30 ,i walked into what seemed the be the most warm and cozy place. They were quick with receiving me and bringing me to the back. The dental assistants were compassionate and knowledgeable constantly showing and telling me the process. Than the Dr herself was very nice and honestly felt like she was trying to get me on the right track while making sure i was takin care off.!Plus the whole time it just feels like a family atmosphere. I would 10/10 recommend if u have any issues to give it a shot and set up an Appt….Thank you again for all yalls help!!!!

Great first experience. Rachel is friendly and smiling when you walk in the door and they have bottled water while you wait. Decor is nice, doesn’t have that typical hospital feel that most offices do. Everything seems high tech, from the online patient forms you fill out prior to your appointment, to the TV’s with Netflix and headphones to make you more comfortable. They even have TV’s mounted on the ceiling so you can watch while you’re laying down. Dr Castles is great. Very personable, explained everything very well and was accommodating and transparent with my insurance coverage and a plan of action. While I’ll never get excited about going to the dentist, they made everything much more pleasant.

I had a great experience with Dr. Castles at Holy City Dentistry this past week! Having not been to the dentist in a while, I was thankful for how thorough my exam was and that Dr. Castles took the time to show and explain to me what she found! The exceptional facilities were an added bonus and I loved being able to distract myself watching Netflix while my cleaning took place. I already found myself recommending Holy City Dentistry over the weekend and will be back soon!

Megan Beatty (Source: Facebook)


My first experience here at holy city! I have anxiety and have been staying away from the dentist for years. I made my appt online and received call from someone next day. Everyone is so sweet, calm, and informative. I was so comfortable and relaxed I didn’t even recognize myself. Everything was great, Netflix, blanket, water, and great future plan. Super honest and very helpful! I could go on! Wonderful, see y’all soon!

What a great experience! Everyone is so friendly and the facilities are the best I’ve ever had! Massaging exam chairs and Netflix while you’re being examined are a big plus! But Dr Castles is the best part! She approaches her patients with the warmest and most calming attitude and treats everyone like a friend. She even took the time to explain and show me her findings so that I’d understand what needed to be done for next steps, but also kept things as efficient as possible. I never felt like I was being lectured or judged and that down to earth approach was very different than your typical dental exam. Highly recommend seeing the team!

Dr. Castles and the Team at Holy City Dentistry are amazing! The opened up around the corner from my home, and after a poor experience with a prior dentist and an impending issue with a molar, these ladies came to my rescue. They were all so kind, and accommodating. Their precautions for COVID are in line and enforced. Their office is beautiful and welcoming – each room having TVs and music if you like! They truly make going to the dentist an enjoyable experience!
