Dr. Castor and his staff are very rare in this day and age. Recently I had a surgery and my front two teeth were busted out when the intubation was removed. Although the anesthesiologist said that he was going to cover fixing my teeth, it was impossible to get in touch with him once I left the hospital. Less than two weeks later, my 26-year-old son was killed and suddenly I had a funeral to go to, unrelenting grief that no parent should ever face, and two missing front teeth. Dr. Caster and his staff made sure that I did not go to my son's funeral without front teeth. Typing that now, it sounds funny, even to me, but there was nothing funny about it at the time. It waswas devastating. Not only did they make sure I had temporaries to wear to the funeral, but they also - including Dr. Caster himself - sincerely wanted to know how I was doing and even shared a similar situation with me one of them has been in. They took time to be human and treated me like more than just someone there to get my teeth done, but instead like a friend. Due to many health concerns, I see a lot of doctor. it is rare to see doctors that take the time that this dentist office took for me. And all of this is on top of doing superb dentistry work. read more

These guys are super cool and very comforting. The new dentist filling in for Castor is equally as amazing.

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 read more

When I entered the front receptionist was very friendly. Sally, the dental hygienist, was very knowledgable and put me at ease. She was gentle and talked to me throughout the cleaning. The office was clean, staff was friendly and I highly recommend Dr. Mark S. Castor to anyone. read more

Dr. Castor and his staff has always treated me like family these past 30 plus years that I have needed their services. I appreciate that very much. Thank you Dr. Castor & Staff read more

Personable, friendly, professional, efficient and from just one visit It's apparent they're very capable of providing an as enjoyable experience as possible at the dentist. read more

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! read more

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. read more

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!! read more

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. read more

This is an awesome office. If you want to go somewhere where you have no doubt you are dealing with professionals who really know their field, and are warm and caring- this is your place. read more

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! read more

Very friendly, warm, knowledgeable and professional staff. Great overall experience. This is my new dentist!

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. read more

They say one price for dentures online than when you get their the price over doubles. same thing when it comes to pulling teeth

So if you've seen me in real life, you know my teeth are pretty jacked up. Or rather, they aren't the shiniest pearls in the sea. Well, these days they might resemble an oyster pearl from the Gulf, what with all that free oil they keep giving away. This is partially due to my (prior) horrific dental hygiene habits, 12 years of smoking, and daily coffee intake (black please.) Thus, I feared the evil dentist, and avoided him at much cost to my social life for many, many years. Last year I broke off a bunch of one of my teeths somehow, and it needed repairs, and I didn't have insurance and had to use some cheapo crap place that really, really hurt and took forever and was miserable and oh god why didn't someone make me floss and brush all the time like you are supposed to? Anyway last year I got a bitchin' job with dental benefits and based on prior reviews here, I found Dr. Castor. So Dr. Castor kicks ass. So does his whole team. Dad-gummit for the life of me I can't remember the hygienists' name who deep cleaned me but she did a fantastic job, pain and anxiety free, which for me is a big deal. (And all this my friends, without the benefit of my dearly beloved NO2.) In summation, as much as a dentist can be awesome to someone with such effed teeth as mine, I gotta say I love Dr. Castor, his whole office, and the brave work they do on people like mine's neglected teeth. read more

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. read more

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. read more

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. read more

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 ... read more

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! read more

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! read more

This was probably overall the best experience I've ever had with a dentist. Everyone was extremely nice and helpful, no one was "too rough" on me, and they are open on Fridays! I didn't know this but that is uncommon, at least in Austin. I was dealing with extreme amounts of pain and needed some pain medication ASAP, and both of the assistants worked hard to make sure that happened for me. (I made the appointment at 10:30am that day.) When I returned to get my wisdom teeth removed and some fillings, everything went smoothly. He definitely has great "chair-side" manner! Very honest- he even returned $20 to my credit card because one of my fillings went easier than expected! I avoided the dentist for 6 years before this visit- so usually a dentist visit is nothing to rave about. Just awesome all around. read more

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. read more

I went to Dr. Castor because the reviews on yelp were so good. The staff was really nice. However they told me on the phone they accepted my insurance until after I got out of the chair changed their tune and said they didn't. While in the chair Dr. Castor told his assistant while looking in my mouth,"Ok now time to check for mouth cancer!" To say that out loud was first of all scary and second off all...not very caring. I left that appointment feeling demoralized. Thank god I do not have mouth cancer but why put that weird energy out there to put fear in your patient. Never going back. read more

I woke up this morning with a temporary crown that had popped out of place. And of course, it's the morning of the 4th of July, and likely a 4 day weekend for everyone else. I called Dr. Castor's office hoping to get an emergency number and did as well as his text/cell number. I sent him a text, and he called me back within 3 minutes, Within 1 hour I was sitting in his chair getting my crown cemented back in place. Pretty amazing guy, and I could tell that he genuinely cared about me, and that this wasn't an inconvenience for him. And what's even better about this place is that this level of service is carried our every day by the entire staff here. Their level of professionalism really shines and you can tell that each of these folks love working together as a team dedicated to making sure each customer is happy, satisfied and most importantly--comfortable. I was really blown away by the fact that this dentist would drop everything at 8:30am on the 4th of July and drive into work to fix me up. Dr. Mark Castor is the dentist I want in my corner forever. GO read more

I met with Dr Castor and was hoping to have him complete a crown. My insurance changed though with the new year and I have to find someone in my lousy HMO network. Paloma discovered this while I was in the exam chair and she and Dr Castor were completely understanding and went out of their way to help me navigate my new insurance. Paloma called a week later to check on me. So, even though I didn't get my crown here, I'm very impressed with the customer service and helpful staff. Dr Castor was also super professional yet approachable and I really wish he could be my new dentist! read more

Third time here. Always professional, never a real long wait. Castor does a great job of explaining the process.

Used to hate going to the dentist but now after being his patient of 3 years, I am anxiety free and its simple & quick! Like that everyone is straight forward and cares for the patients not their money. I love their text reminders for my appt the next day or when im actually due for appointments. Thank you so much guys!! read more

Just wow. I didn't catch the woman's name at the front desk but she was warm and welcoming. Nicole did my cleaning she was so friendly and from the time I sat down she made me feel as if I was catching up with an old friend. She was very knowledgeable and made me comfortable and excited to meet the doctor speaking highly of him. Sylvia was the doctors assistant and she was also so sweet and funny! The doctor was hands down incredible. His staff is truly a reflection of him. He was gentle, patient and very kind. He made a point to make me feel comfortable with some small talk and cake across very genuine. I won't be going elsewhere. To top things off my appointment went by quickly! Beyond impressed. read more

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. read more

It was an awesome experience. Painless and surprisingly in a short amount time. Everyone in the office is extremely helpful and explain every step of the process. I highly recommend. read more

Great dentist. Will not change unless forced. Dr Castor cares about his patients and spends time addressing any concerns or questions. His office provides a comfortable atmosphere and it seems he treats his employees well. He is very fast and efficient. I highly recommend him to everyone. In office wait times for a scheduled appointment can be long but worth the wait. read more

I, like most of you, hate going to the dentist. Dr. Castor makes everything easy and comfortable. He's laid back and makes getting your teeth poked at as smooth and relaxing as possible. Plus the text message reminders are nice and I never have to wait long. Dr. Castor is the best. read more

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!! read more

Dr. Castor is very personable and the hygienists are pleasant even while chiseling away at plaque. Dr. Castor always performs oral cancer and tissue checks which is something I hadn't had prior to seeing him and find it very reassuring to have someone keeping an eye out for general oral health as well as the specific health of my teeth. A++ read more

Great staff and Honest experienced dentist. The doctor communicates very well and provides superior clinical care. I strongly recommend him read more

Great friendly staff! I'm glad my coworker referred me to Dr. Castor. Had my first visit and very happy with how helpful everyone in the office was from the receptionist, to X-ray tech, dental hygienist to Dr. Castor himself. I have to have a crown put in and a couple fillings and they worked out a payment plan for me and made sure to check on my insurance coverage for everything. Highly recommended! read more

I felt so at ease as soon as I walked in the door. The office staff is so friendly, Sally the hyginist was wonderful, so gently when doing the xrays, which is the part I don't like. And my teeth were so clean when I left. Dr. Castor was great too, I have pretty good teeth so didn't need to see much of him, but I am so glad to have found them. Just sorry it took so long read more
