Adrian R.
People are very nice and funny. Takes 10-15 minutes for the appointment. Worth the money!
Jennifer A.
I highly recommend beach cities orthodontics, I love my smile and the orthodontics in the back are the best <33 over all an amazing experience!
Response from the owner:Thank you so much for the sweetest review!! We are so happy you love your smile!
Luz B.
Had the best experience here. Everyone is always so nice and always makes me feel comfortable. Dr. Brothers always listened to my concerns and ensured she walked me through the entire process as every place is different. She always provided updates and let me know exactly what was happening and what to expect. The assistants were also great!
Response from the owner:Thank you, Luz! We are delighted to hear about your positive experience and appreciate your kind words. Our team is dedicated to creating a welcoming atmosphere, and it’s wonderful to know you feel comfortable with us.
Jason S.
Whole experience was great! Dr. Brothers was extremely thorough and the whole team was excellent. Especially Caitlin. Pricing was very fair, I shopped around quite a bit. Going to a dedicated orthodontist is way better than having your general dentist do this. I’m not going to wear my retainer just so I can come back and have this experience again.
Response from the owner:Thank you so much for the kind words, Jason! We’re so glad that you trusted us and had such a great experience. And while we definitely want you wearing your retainer, you’re always welcome to come visit us and grab a cookie at the front desk anytime!
Benedict M.
We had such a great experience here. My kids smiles are so pretty with their help. Highly recommend them. The staff is always so professional and attentive
Response from the owner:Thank you, Benedict, for your wonderful feedback! It's fantastic to hear that your kids left with beautiful smiles. Our team is dedicated to providing exceptional care, and your recommendation means a lot to us!
Celyne C.
My son just got braces before Christmas. We had been coming in a few times before to check on the readiness. What I love about this place is they are so upfront and honest! My son wasn’t ready for braces yet when we first went. He still needed some teeth to fall out some to come in and they didn’t try say we still needed to get them on so they could make money and drag out the process as we experienced at other places with my other kid. They genuinely care about their patients and will set up the best plan that works personally for them based on the goal and readiness of the patient. They are all super sweet and accommodating, they have all the latest and greatest stuff and I’m thrilled that we are using them for my son’s orthodontic needs. I would 100% recommend them!
Response from the owner:Thank you for your thoughtful review! Our approach is always to put what’s best for the patient first, and we’re so glad you felt our team was honest, caring, and focused on your son’s needs. We truly appreciate your recommendation and are excited to continue supporting his smile journey!
Shelley B.
Everyone was very nice. They get back to you quickly if you have issues. Good with young children. Very thorough with explaining the process using 3d pictures. Flexible down payment and payment plans. They let me wait until my fsa started over before starting the plan for my son.
Response from the owner:Thank you so much, Shelley, for your kind words! We’re grateful for the opportunity to support your family and are so glad you felt informed and comfortable throughout the process. 😊
Krista R.
Getting the best adult ortho care here! Everyone is great! Doctors and staff are really amazing. Loving my results!
Response from the owner:Thank you for your wonderful feedback, Krista! We’re thrilled to hear you're receiving excellent care from our dedicated team. Your satisfaction motivates us to continue providing exceptional orthodontic services.
Carla F.
Overall, a wonderful experience! Dr. Brothers and her team , especially Ms Lily, are so kind and gentle! I’m very satisfied with my results.
Response from the owner:Thank you so much for the kind review! We’re so happy to hear you had a wonderful experience with Dr. Brothers and our team, and we’ll be sure to share your sweet words with Lily. We truly appreciate you trusting us with your smile!
Ilise W.
So excited to get my Invisalign off today! Thrilled with the results. Dr. Brothers and the team at Beach Cities Orthodontics have been terrific every step of the way. Highly recommend!
Response from the owner:Thank you so much, Ilise, for sharing your excitement! We’re thrilled to hear how happy you are with your Invisalign results. Dr. Brothers and our entire Beach Cities Orthodontics team truly appreciate your kind words and recommendation—it means so much to us!
Sarah K.
We have loved our experience at Beach Cities orthodontics! From the start, we felt welcome and the process to get started was not intimidating and they really informed us of all the choices and explained everything so well. The staff and the doctor are so friendly and kind. So far, the treatment plan we are on is going well. Having a high schooler makes it easy to have scans and the app, so she can be accountable and responsible for her own progress. It has helped our family to have a payment plan that can work for us. Would definitely recommend this practice!!
Response from the owner:Thank you, Sarah! We're thrilled to hear about your positive experience at Beach Cities Orthodontics. Our team is dedicated to providing a welcoming environment and personalized care. We appreciate your recommendation!
Scott M.
Our daughter just had her braces removed. Dr. Brothers and the entire team made us feel like family the entire time with them. Never thought I'd say we will miss an orthodontist, but we will.
Response from the owner:Thank you so much for your review, Scott! It is our pleasure and we will miss you too!
Leanna P.
Always a great experience going to this office. Everyone is very friendly accommodating and just an overall great experience. Definately love that it is very kid friendly.
Response from the owner:Thank you so much for your kind words. We’re so happy to hear that you always have a great experience with our team!
DIANA M.
