Like so many, I have never been a fan of the dentist.  I would go because I knew I needed too, but since discovering the awesome staff and cool technology at this location, I enjoy going.  The same building also has an kid side. The dentist made sure my son was confortable, and even sang songs while he brushed my son’s teeth.  Cute!   I would recommend this place!

Definitely the best dental office I have ever visited. The staff there is super friendly and helpful! My hygienist Ilse was great! She took really great care of me and provided me with lots of great advice on taking care of my teeth! This office is about 30 minutes from where I live but the drive is definitely worth it! I highly recommend this office!

I was lucky enough to be part of their free clinic! I was treated so nicely and am over the moon with the fabulous results from my visit! They listened to my concerns and we’re so patient with my silly fears. Thank you so much for being so fantastic!

If I could give this organization six stars I would. When you first enter the door you are greeted with stellar customer service from the receptionists, followed by attenuitive dental hygentists whom ensure your needs are met, ending with an intelligent & knowledgeable Dentist that connects with their patient on a personal level. Big shout out to Dr. Castre, Dr. Bebeau, and Jenna. Y’all are awesome!! #killingit #dentistrcoolnow #dontfearthedentist

I recently visited this office and boy was I blown away! All the staff was super friendly and attentive! My check in process was smooth, as well as my x-ray process, Izzy, was very patient and precise. My cleaning is was set it over the top, Ilse Barranco, the dental hygienist was very caring and patient! She answered all of questions/concerns and always made sure I was comfortable! Would definitely recommend this dental office

Yesterday was probably my second or third time at this dental office. Once again I was really satisfied with every single aspect. Excellent customer service all around. Starting from the receptionists up to the dentist. They didn’t make me wait. I got a great dental cleaning at a really competitive price! I guess I’ll stick around with them… 😉

I went in because I lost my retainer years ago and now I have to get braces again…at 32:( I sought out this location because it’s close to home and they have hours that work around my schedule. The ladies at the front desk were friendly and checked me in right away. They took X-rays and photos of my bite and smile. The orthodontist took his time explaining the issue and going over my options. I fully expected him to pitch Invisalign to me, but he actually made the case for braces…he said they’d be significantly cheaper, more effective, and my treatment would take less time. Does it suck wearing braces as a grown up? Yes…but not worth the extra $2k out of pocket for Invisalign. They went over the total cost with me before proceeding and scheduled my follow up appointments right away. I honestly can’t think of anything they could’ve done better.

I visited this office for the first time last week and was blown away at the level of consideration and care. The front office was helpful in getting me checked in, my x-rays went smoothly, and Dr. Castre was incredibly attentive to my concerns. I walked away feeling positive about my treatment without feeling overwhelmed by the cost. I will definitely be returning- this office was a great find after a few less than stellar experiences elsewhere.

Really really nice they will take care for you and you won’t have any problems at all it’s not crowded and not that much workers which I like and there are not that much people/workers in the room only about 2 to 3 people.rooms are not crowded and you can watch TV and you can choose what channel you want if they have the channel so 5 stars love you guys

I absolutely love this place! The staff is so welcoming and beyond caring.  I was extremely nervous going but as soon as I got there all that changed because of how friendly they are. They really treat you like they want to help you and actually care for your needs not like other dentist offices where if you don’t have insurance or the money up front then that’s just not there problem. Everybody needs to start coming here. I loved the receptionist, the dentist I seen and the man who did my ex rays was awesome.  Keep up the good work guys!!!

Super attentive and create a very relaxing atmosphere. (I hate going to the dentist, so that’s important.) Returned for a second opinion after trying out a new practice and am extraordinarily happy I went back. Got an understandable treatment plan – and it made sense. (I am a physician so I value such things.) Go – and your teeth will have an easy time of it – and you will too.

This dentist office is AMAZING – I’ve been taking my daughter here for the last two years and finally made an appt of my own this past week. Hands down the best dentist office I’ve found. The receptionists on both sides (the adults and the pediatric side) are super friendly, personable, and provide outstanding customer service (Perla is awesome!). The assistants and hygienists (Ilse and Stephanie) are super sweet, friendly, personable, gentle, and very patient. Dr. Ellis, Dr. Sharma and Dr. Castre are phenomenal. No need to look for any other dental office – This place is top notch all around.

I am a person who has an honest phobia of the dentist. Every dentist Ive been to so far has had me clutching the chair beneath me in terror. But at this place, everyone is super friendly and does their best to make sure I feel comfortable. There has never been any pain in the several procedures I’ve had done here (which includes two root canals, every dental-phobe’s nightmare!) Every professional I’ve seen here has been excellent! The lovely ladies at the front desk are great too. They refer to me by name when I walk in the door and are prompt at helping me out. I want to point out that they’re also helpful with setting up payment plans for the more expensive procedures. I’m so, so glad I found this place! I’ll be going here for as long as I’m in this area. Having a great place like this relieves so much stress!!!!

Recently began treatments here, simple cleanings, but I already love the office & know they can take care of anything I’ll need. The staff is super friendly and knowledgeable. I had the best hygienist, Ilse Barranco, who even worked on my mouth with braces with no issues! She made me feel so comfortable and confident in this office! It’s also super affordable as I didn’t have insurance during my first visit. I definitely recommend this place – who doesn’t love a friendly staff, free coffee while you wait, & obviously an amazingly talented team! 🙂

I had both of my children go to the child side of their practice in my case. Not only was the staff very friendly, but they broke down all of the billing, and how insurance worked with it, so I could feel comfortable with paying for my little cavity machines! The x-rays are all digital, so instantly available, and all of the modem technologies you would expect and then some from a modern dentistry. These folks really have the right idea, when it comes to how to treat, and work with a patient. Oh and the kids side, has fun toys, games, and videos for the kids to watch that are actually interesting to the children while they wait. 5 stars for sure!

Savannah R. from Phoenix, AZ (Source: Yelp)


From the moment I walked in to the moment I left, I felt genuinely cared for. The dentist pulled me into his office first thing to ask if I had any questions or issues with my teeth. It was much more personable and caring than asking after I’m already in the chair! My hygienist was Ariel and she was awesome! She was very personable and friendly, made me feel at ease. She also was very caring, always asking about my comfort. I would recommend this office to anyone!!

Crissa R. from Big Bear Lake, CA (Source: Yelp)


This dental office is by far is the best dental office I have ever been to and it’s all because of the staff! I have been in need of a cleaning and exam for quite some time, as I was driving to Sprouts I happened to stop in to see what they would charge me for teeth cleaning without insurance. That day they were able to get me the information I needed and set an appointment for later that week. Last Friday was my appointment, I was greeted by their friendly staff whom even made small talk with me during my short wait. The dental hygienist, the dentist and the dental assistant were all very pleasant as well. They were able to modify my exam to no x-rays because I am pregnant, each staff member checked on me and made sure I was comfortable while in the exam chair. Each exam room has their own TV and remote for your viewing pleasure during any procedure, the entire office is clean and new. I was already satisfied with my experience and to top it off I received a personalized thank you card in the mail yesterday, thanking me for choosing their dental group! How cool is that!? I definitely felt appreciated as a customer and I highly recommend this dental office.

I had taken my son to another Dentist and about a year later come to find out they were capping kids teeth for money. I now have a daughter and needed to get both my son and daughter seen at the Dentist. Yesterday both my son and daughter were seen here and boy was I wowed! Everyone and I mean EVERYONE in the office was so welcoming, nice, friendly, and made my children feel very comfortable! My daughter does not do well with new people, and I could not believe she did not even cry once while they brushed her teeth! My children are my everything and I am so happy to say I found an amazing office for my children! Thank to every staff member there that made my children feel happy and have clean teeth!
