I had the best experience with the entire staff here, including Dr. Castor. They were so thorough with everything they did and all procedures needed are discussed in detail, including out of pocket costs. I couldn't be happier with the attention to detail and the friendliness of the entire staff!

Dr. Castor and his assistant Emma are the best dental team I've ever been to! They're super friendly and professional, and really make you feel relaxed sitting in that chair. Not only that but Dr. Castor is a perfectionist and made a bad chipped tooth look perfect and flawless again. I would highly recommend Dr. Castor's office to anyone needing dental work.

Had a temporary bridge crown assembly reinstalled. On short notice, a time slot was found and the quick prep and replacement was satisfactory. Thanks to the fine staff here to make it easy and prompt.

Dr Castor has been my dentist for over 15 years now. He and his staff are truly professional and caring people. They are also conscientious of cost. That is a rare combination in any business. This is truly the best dental office I've ever been to, and it will be a sad day for me when he decides to retire! They are simply fantastic. I could not recommend them any more highly.

I have been going to Dr. Caster for 8 years and adore he and his staff! They are professional, kind, welcoming and thorough. I always enjoy checking out his collection of Southwestern artwork. A real treat! I have referred many friends throughout the years. Never pushy and always consistent. Can't recommend enough!

My experience with this dental practice was great. They were professional and courteous. Normally not a big fan of dentists, but Dr. Castor was well informed and listened to my concerns. My hygienist, Sally was absolutely wonderful! If my previous dentists and hygienists had been this good, I wouldn't have avoided them. I would give them 6 stars!

It was hard for me to find a really good dentist in south Austin and I'm glad I was referred to Dr. Castor. His entire staff is friendly and professional. They are super safe with Covid protocols and keeping everyone safe. I really like my dentist. I never thought I'd say that. Ha!

Dr. Castor is always professional, and has never over charged me for any service, if the service isn't needed right away he will let you know. Very honest and dependable. You will be happy and very please with the service he provides.

I'm very pleased with my recent visit. The office staff were able to fit me in within a few days after a semi-emergency. Dr Castor and his assistant were very cordial and worked with a great deal of care and coordination on my soon to be new crown. Dr Castor and all his staff are all very pleasant.

Glad to get my regular dental prophy. Enjoyed visiting with staff. Wish that, at least twice in a row, I would receive the same or similar paperwork at the end of a visit that clearly showed the current balance on my account, full cost of the procedure that would be billed for the procedure done that day, perhaps your best guess as to what, if anything, you expect to receive from my insurer, and what I am billed that day.

And that's in addition to a credit card receipt. The document i received yesterday with the requested information in bo way resembled the document I received at my last visit.

Wow. I wish I would have found Dr castor's office years ago. He is so knowledgeable and kind. As I left I heard him tell somebody that he wanted to just tell them thank you for doing such good work. The hygienist was so extremely nice and knowledgeable also. I learned a lot on this one visit. I'm really grateful to have found this office

I went to Dr. Castor's office today to get a second opinion regarding a dental question. I arrived 10 minutes early to my appointment and they were ready for me. I was quickly checked in and escorted to the examination room. The dental assistant was great and Dr. Castor came in shortly after I arrived. I was very impressed with the quality of care Dr. Castor and his entire office provides.

Not only did he answer all of my questions but he took the time to explain each item in a way that was easy to understand. I was thoroughly impressed by the examination and the quality of service. His office staff is equally impressive. Lucy and Ana were so incredibly helpful and kind when I initially called the office to set up the appointment. They followed up with me and provided superb and efficient service. I couldn't have asked for a better experience. I would recommend anyone to go see Dr. Castor. I will most definitely be referring my friends and family to his office!

Dr. Castor is great, actually all of the staff is! No long wait times, no short tempered staff, no billing issues and getting scheduled when needed has never been a problem. Genuinely kind folks who make your experience as pleasant as possible and for a family of 5, it's been much appreciated!

Today I'm leaving a review on this dentist office. So I arrive and speak to the woman at the front desk. She was sweet. I wait for about 40 minutes off schedule for my teeth cleaning. They did an okay job. When I went home and checked my teeth out, I noticed some spots that they complete missed. After my teeth cleaning, I was informed that I might need to get surgery on one of my tooth's. Castor came in and talked to me but he just felt very "over" the situation. Didn't feel any kind of engagement with him.

Like he just came to tell me and as soon as he was done wanted to get the hell away from me. I don't know. I hope it wasn't something I did or said. : were my teeth that bad? Anyways, that was my dentist for about 7-8 years. But I will be finding somewhere else to go.

Went in recently and had a bad experience. I thought from the previous reviews everything would go smoothly, but I was wrong. Making the appointment was a breeze. But when they started the cleaning I was told my gums were bad. I get my teeth cleaned regularly and never have I been told this. The lady I think her name is Sally would not clean my teeth but said I needed to come back.

Then the doc took forever to come in and see me. I was told I needed 2 crowns. Really? So now I'm having the xrays they took sent to my previous dentist for a second opinion. Seems a little sketchy.

Just moved to town, found Dr. Castor's practice through Google and Yelp searches, and couldn't be more pleased with how I was treated for my 6-month checkup. The facilities are clean and modern and the staff is unfailingly polite. Sally, my hygienist, walked me through every step of what she was doing as she was doing it. Dr. Castor was very nice, professional, and knowledgable. If I could give them a 6-star rating, I would.

I really enjoy going to the dentist, because the staff are always pleasant, informative, gentle and generally enjoy their job. Doctor Castor is a straight shooter and provides free comedic entertainment. He does what is necessary to keep your teeth and gums healthy. I would recommend this dentist to anyone interested in a good dentist.

Reviewing Dr. Mark Castor is easy. I've been going to him for three years, and he's the best dentist I've seen. I knocked out some teeth in a fall on concrete while walking a young frisky dog, so have seen him a lot. Mark is gentle and attentive, and all of his work has been of a high quality. Sitting in one of three chairs, you will be hearing soft music and seeing a relaxing view of trees.

His staff is experienced and caring, both chairside and in the office. If something comes from the lab that doesn't seem perfect to Mark (even if it's a cap a tiny shade off-color) he will send it back. To sum it up, he's a casual perfectionist and I'm glad he's there!

Dr. Castor and Nicole are terrific! They took the time to diagnose what was going on with my tooth and fix the problem that day. I was in a great deal of pain and they were able to alleviate ALL of my symptoms. I'm very thankful for both of them. They are highly intelligent, kind, and very personable. Office is really nice and in a great location. The ladies up front were also very friendly. Highly recommend Dr. Castor!

Hands down the best dentist and staff I've ever encountered. I have super sensitive teeth, staff are always understanding, apply numbing cream even before a routine cleaning. Dr Castor does an oral cancer screening at each exam-never had another dentist perform such exam, and as a previous oncology nurse, I know how important this screening is. Dr Castor is very thorough, honest, and gives me the breakdown of pricing on all procedures prior to the appointment. I now live about 45 min from his office, but still keep him as my dentist because of how amazing he and his staff are. You cannot find a better dentist/staff in Austin!

Dr. Castor and Staff have been incredible in taking care of me. I would recommend him to all my friends and family. As to Chantill. oral cancer screening is part of Today's dentistry. To have a dentist who doesn't perform this screening would be absolutely prehistoric. There is NO political correctness when it comes down to your health.

Anyone who knows me, knows I have been going thru hell on earth with my teeth. Mark and his staff are kind, helpful and considerate. Mark helped and explained to me what was going on, and how we could fix this. Wow what a difference in attitude, compared to the "dental puppy mills all over town" that just wanted the money. Mark is one of the best of the best I have found in Texas, and I would recommend my friends and family to him. He helped restore my faith.

Everyone in Dr. Castor's office was friendly and helpful! I didn't have to wait too long- less than 10 mins in the reception area, and then I went back for my cleaning. Janis, the hygienist, was very nice and knowledgeable, but she was definitely NOT gentle during the cleaning. That is my only real complaint. I'll say this- it wasn't the worst or most painful cleaning I've had, but it also was definitely not the easiest or most pleasant.

I have regular cleanings, so I didn't have any real problems, but still the cleaning took almost an hour and my gums were pretty sore afterward. Dr. Castor didn't try to sell me on anything extra (besides recommending a night guard, which I know I need- he told me the price and said he would let me decide, no pressure) and recommended a little reshaping on my front teeth because there is some chipping.

He said he would do this free of charge, but we kept talking for a while and I think both of us forgot about it during the rest of the appointment. I only remembered once I was back at work, and am kicking myself now for not taking advantage of that, but it was a nice gesture anyway. He does seem to care about the patients and seems to be rather conservative in treatment, which I appreciate.

Like a lot of people, the idea of going to the dentist frightens me. I haven't taken very good care of my teeth, and in my mid-30s it's starting to show. After reading the wonderful reviews on Yelp for Dr. Castor, I decided to book an appointment for myself and my fiancee to have our chompers taken care of. First off, the staff is a group of the loveliest and kindest people I've had the experience of working with.

After my first visit and cleaning, I experienced some extreme tooth pain from my broken wisdom tooth and ended up in the emergency room from the pain. My fiancee had called their office late that night trying to get a recommendation on what to do, but they were closed (as it was 1am on a Saturday night) and not available. Despite this, as soon as the next day rolled around we received a phone call from Melanie making sure we were okay and had everything we needed.

I want to also mention that they called me back on a SUNDAY when their office was closed. This is dedication and genuine care for their patients that I have never experienced before. Secondly, Dr. Castor is very kind and patient with his patients. He took time to explain everything that I needed to be done on my first appointment, and when we went back the second time to have some work done on my fiancee he even prescribed some more medication to help with the tooth pain while I waited for my oral surgery appointment. I would recommend Mark Castor, DDS to anyone that asks for a good dentist in the Austin area.
