My children have been going here for the past few years and the staff and dentists here have always been so nice and made them (us) feel comfortable and well taken care of so my husband and I decided to give them a try on the “adult” side for our routine cleaning’s. They were really nice and welcoming and got us in and out. We couldn’t be happier.

I just had a cleaning and Alexis was so great and helpful, she answered all my questions and she was so kind. She took her time cleaning my teeth and she was so friendly. I have been coming here for a while but I love the staff and Dr, I also brought my kids here. In love, both sides are the adult and kids.

I’m a new patient here and I’m very pleased with the cleanliness of this facility and they had me back and done in a timely manner. And my hygienist Kristy was awesome very friendly and gave me a pain-free experience. I’ll definitely recommend Mobile Bay dental in semmes to my friend and family.

DO NOT GO!! I’ve been taking my son here for about 6 years now. Today I was 9 minutes late from being stuck behind a school bus, and the staff refuse to see my son even though their was no one in the waiting room and this was the first time I’ve ever been late. They said they no longer have a grace period. This was rude and unprofessional! I will not return!!

Great care, made sure I was comfortable. Was one of the best visits I’ve had to the dentist! The price was also more fair than others I shopped around with. Was fortunate enough they could squeeze me in on a Friday on short notice. I will definitely be back for the rest of the work I need! Thanks to the staff I had working on me!

This place is great! When I first walked in it was a little hectic, they have a play area for kids which is amazing, but the also have a adult only waiting room which was very nice. The staff here is top notch. Everyone from the girl at the desk that checked me in to the dentist was friendly and knowledgeable. I have a little anxiety when seeing any doctor and the dentist was kind and understanding of that. I had a tooth pulled, painless and unbelievably quick. I would recommend this place to anyone! Thank you Mobile Bay dentist!

Dr. Gast and his assistant are AMAZING! I have had several dental issues, and he ALWAYS takes his time and does a remarkable job. He is extremely professional, and cares about his patients. His assistant does also. I wish I could give them both more stars, but he will forever be my dentist. His office staff is ALWAYS friendly. I highly recommend Dr. Gast and his staff.

Just had my 3 grandsons there for their check ups and cleanings. My 9 y/o grandson developed hives yesterday and had to go to the ER because his mouth had swollen. He was fine this morning but broke out in hives again while we were at Mobile Bay Dental & Vision. The staff was concerned and made sure he was alright. They checked his temperature and gave him Benadryl. Since the Benadryl had a bad taste someone gave him their bottled juice to drink. I appreciate the concern and attention shown to my grandson and that someone gladly gave their drink to him to help him (probably their lunch drink). Thanks Mobile Bay Dental & Vision!

We love the vision side with Dr. Perry and her her associates, they are all very sweet! On the dental side we loved having Dr. Gast do oral surgery on my son to remove his wisdom teeth. He did a fantastic job and my son hasn’t had any complications.

Great place!! Awesome staff!! Even tho there was a miscommunication with the appointment times, they fixed it. The vision staff stayed an extra hour so they could see my 3 children. They never rushed us, still took their time to make sure everthing was correct. They found what prescription glasses my son really needed because his previous eye doctor gave him the wrong prescription glasses. Best place in mobile to take your children, very accommodating and they really do care about their patients and parents.

Such an AMAZING staff! My kids have been coming here for years and we always have a wonderful experience. The environment is inviting and entertaining. Kids are treated with courteous attentive care. I often have a hard time convinving my kids to go home. I highly recommend!

They have the friendliest employees. They make you feel welcome every-time you come in. Defiantly makes it not as bad to visit the dentist or get your vision checked. I have both done here and I will never go anywhere else.

There hasn’t been many times I can say that I’ve walked out of a dentist’s office SMILING! (Crooked grin because of the novocaine) I cannot say in words how impressed I am with Dr. Gast. Such a delightful and cheerful person! He made me feel comfortable in spite of my dental anxiety, went above and beyond to make sure I was satisfied! Thank you all so much and I have finally found my dental home with Mobile Bay!

I went to the Vision side and the staff there was amazing. They make sure you are happy with the contacts they prescribe to you or you can come in and change until you are seeing perfect. I have changed 3 times and have been given the other prescriptions for free to make sure they give me the ones that help me see the best. Thank you ladies you are wonderful.

Dr.Gast removed 2 wisdom teeth and 2 molars that and did 2 fillings. He was so gentle and worked so good with me because I’m terrified of the dentist. My recovery when so good I didn’t have hardly any pain. I will recommend them to anyone. All of the staff was polite and gentle!!

New building with new equipment. Was impressed with all of the staff I came in contact with. Friendly, yet professional. Went for a teeth cleaning & check up. First time EVER that I can remember that I had NO pain from the teeth cleaning. I have some sensitive areas and no matter how careful the hygienist are, I end up digging my nails in the chair arm…..The children if they so choose, can enter the building by following the small foot steps leading to the child size door (awesome idea!). Upon entry they will find a separated waiting room from the adults that includes an inside play area and gaming stations. Can’t believe I am saying this, but I am already looking forward to my next appointment and would have used the small door if I could fit thru it!

The staff here are amazing and make you feel right at home. We (my husband & I) recently had our routine cleanings done here for the very first time and I must say there was nothing awkward or uncomfortable about the experience. They were nice, courteous, and got us seen at a reasonable amount of time. Our kids have been going here for years for both, dental and vision, I’m not sure what took us so long to make the switch but it’s pretty safe to say this is officially our family dentistry home.

My experience there was awsome. Some of the best people you will meet. Just good people. They will treat you the same weather you have bad teeth or have a Hollywood smile. They take there time and really make sure everything is the way you like it before you leave. The girls at the front desk are great to. Any billing question you have they can answer it.

Dr Gast, Ashton, Kaylee, Dr. Q, Dr. Guess,and so many others that I can’t remember but Please know that I am appreciate oneeach one of you Thank-you so much for the the tender care that you gave me today which is Not the exception of care that I get every time I come to you Your team makes my Dental care a pleasure rather than a nightmare as it has been Previously I am so glad that God blessed be me with allowing y’all to be my Dental Team Thanks again You are the BEST This is a inevitable of a kind Medical care place. Not only have they been trying to help save my teeth which I was going to loose due to some of the Rx that I have to take Dr.Gast stepped up to the plate when another dented dropped the ball soto speak because of the very Rx that I am taking and has been right by my side every step of the way. I will be writing the Alabama Dental Board about the outstanding care that I have received . It’s not every day that a dentist will listen to another Dentist opinion who says “Try to save her teeth or she will lose her jaw bone” That dentist is Dr. Gast and I Thank God for him and his assistants Every day. I am going to need vision care in a couple of weeks and I am sure I will be able to get the same Great care right There. If you are privileged to go to the beautiful Schillinger Rd location it is built to accommodate children and has an amazing climbing tunnel to keep them occupied while they wait. That place is beautifully decorated and the staff is just as kind and helpful. I don’t have enough words to tell you how much I appreciate the care I have received from the people that I have mentioned. Oh I forgot to mention they also administer “BOTOX” If you’re in the market. I love the Mall office because I can shop or get my nails done afterwards, I always leave feeling better

Normally my spouse takes the children to the doc appointments. So when I was given the task to have my child’s eyes checked, I was a bit worried it was going to be difficult and I would have issues. Well not the case the laddies were very helpful answered all my questions and even gave advice on frame selection. Super customer experience! We will continue to use this location for are vision needs.

The best dentist office I’ve ever been to!!! My 1 year old daughter felt so comfortable letting them assist her. No literally, you’ll fall IN LOVE with the staff! This is by far the most positive energy.. great atmosphere while waiting to be serviced.. very professional place of business with outstanding personality! They’re patient and they also make you so comfortable. I highly recommend this dentist office. Airport & Semmes location

My kids and I love coming to this location!!! It’s kid friendly on one side and then the adult side is calming and relaxing. The staff is amazing and friendly. I’ve had a ton of work done on my mouth after I had an accident in December and they’ve made everything simple and easy and explain all my procedures in terms that I can understand. Truly recommend this location for the entire family

The dentist was super nice and kept coming back to check on my daughter just to see her reaction of her new caps which she loves. Just putting in the extra effort was amazing. Kelly was super sweet and she gets five stars from us any day. Thanks so much for a wonderful experience. We love you Kelly!!!!!

Can’t say enough great things about about everyone here! I have anxiety when going to the dentist and everyone was very kind and gentle. Also took my one year daughter for her first dental visit and everyone was very sweet and understanding of her impatience!

Mobile bay dental and vision has to be the best place I’ve dealt with when it comes to having my vision checked and corrected. Everyone that works there was super nice, helpful, and respectful. They helped me figure out how to put in and take out my contacts while being patient and helpful. While I was there I went ahead and made a dental appointment also! Thank you everyone that helped me out!

I just got off the phone with Shelby from Mobile Bay Vision, and she was very polite, considerate, helpful, and made a New Patient appointment and checked my insurance benefits very quickly. I am looking forward to meeting her and the Dr. at my appointment. Thank you Shelby,

I love the entire building!! The front desk girls are the best! I came in with 3 of my kids and one of them was my 2 year old son, first time at the dentist, who was nearing the end of potty training and after they finished with him, making his first experience an easy one, and while I was in the back myself, they watched him play on the playground. WELL, he had an accident and peed all the way down the slide and they did not even hesitate! They shut the playground down climbed in that slide and cleaned up the entire thing while I was still in the back! They never once made me feel like it was my fault and they actually blamed it on themselves for giving him water. They are always so sweet and accommodating for me with my 5 kids. As long as this place is open I’ll never go anywhere else! And Callie Taylor, Dr. Q and Dr. Gast are the best!

When we arrived they were having issues with their computer. However the professionalism with which the staff carried themselves, we never knew the computers were down until they told us. They were extremely prompt yet we never felt rushed. My daughter was nervous but due to the kind nature of all the staff she began to relax and actually enjoyed herself. The staff was kind, courteous and very informative. When you couple these attributes with the indoor playground, it’s a Kidz Paradise wrapped in a dental office

I feel very comfortable going to the dental office because everyone is so friendly and they do a great job. The hygienist are very gentle and thorough when cleaning my teeth. My dental work has also been pain free. The crowns I have look good and also fit very well. Both office locations are decorated beautifully for adults and children.

My eight year old had a horrific experience a couple of years ago when having dental work done. The young lady, Jessica, who helped him was very friendly and understanding. After administering nitrous oxide, my son calmed down and the procedure was completed very quickly and painlessly. I am extremely grateful for the patience, understanding and level of professionalism I experienced during our visit and would recommend this dental practice to all of my friends and family.

I love my experience at mobile bay dental and vision Semmes clinic! Mrs Kristy is the best dental hygienist I have ever had! She makes me comfortable and puts me at ease during the whole dental process! Recommend to all my family/friends!
