We’ve had a great experience with my son during his first phase of braces. We plan to continue for phase 2 when he’s ready. My daughter just got braces as well and so far it’s been a very smooth experience.

Response from the owner:Hi, Emily. Thanks for taking the time to share your positive experience. We truly appreciate it!

Lauro A.

Initial consultation was awesome and everyone was friendly. Going back in a week to begin my Invisalign journey! *Update - 12 weeks into my treatment and it is going perfect and I am glad I decided to get Invisalign and at this location*

Final review after Invisalign was removed. Super happy and glad I came here to get treated. Thanks to everyone in the office!

Response from the owner:Hi, Lauro. We are thrilled to learn that you had a positive experience with us!

Kathryn M.

I love Beach cities orthodontics because they are so nice and they have a great attitude. I think that this place is the best place to get braces on and off. I feel like every time I walk in the room I feel welcomed. That is why I love beach cities orthodontics. On 1 to 5 stars I would give then 10 stars. - Brooklyn + Cali age 10

Working with Lanice and her team was nothing short of extraordinary! They exceeded every expectation with their unwavering professionalism, flawless punctuality, and impeccable organization. What truly set them apart was their vibrant, positive spirit — they brought such warmth and energy to every interaction. Their diligence, attention to detail, and commitment to excellence were evident in everything they did. Lanice and her team made what could have been a stressful process feel seamless and even enjoyable. They are a rare find — dedicated, polished, and genuinely passionate about delivering the best. I wholeheartedly and enthusiastically recommend them to anyone seeking the very best!

Adriana B.

Dr. Brother's and staff at Beach Cities Orthodontics have been nothing but patient, empathetic and gentle with my 8 year old. Didn't know what to expect going into Orthodontics but the team at BCO has made it a breeze. It's very comforting to known that there's someone always a phone call away if there's a question or concern. I highly recommend Beach Cities Orthodontics for all of your Orthodontic family needs!

Highly recommend. My son has been going to beach cities orthodontics for a couple of years. Every appointment he has is very quick and efficient. He opted for the Invisalign over braces. His teeth look absolutely amazing. The staff is also amazing.

Response from the owner:Thank you for your wonderful review, Marra! We're thrilled to hear about your son's positive experience with us and that he's happy with his Invisalign results. Our team strives to provide quick and efficient care, and we're glad you recognized their efforts. Your recommendation means a lot to us!

Richard S.

I can’t say enough positive things about my experience at Beach Cities Orthodontics! From start to finish, the entire process was so smooth and easy. Lanice, the office manager, went above and beyond to explain the process for insurance reimbursement, making everything so clear and stress-free. Every time I walked into the office, she greeted me warmly and even took the time to chat with me about my day—it made me feel so valued as a patient.

The entire staff is incredible—friendly, attentive, and detail-oriented. Dr. Brothers is truly a master at what she does. Her expertise with aligners is unmatched, and I always felt confident I was in the best hands.

If you’re looking for top-notch care, I 100% recommend Beach Cities Orthodontics. You won’t be disappointed!

Response from the owner:Thank you so much for your kind words! We’re so glad to hear that Lanice and the team made your experience smooth and stress-free, and that you felt confident in Dr. Brothers’ care. Your recommendation means the world to us, and we’re grateful to have been part of your smile journey!

Alli R.

I have twin boys (one with ADHD) who are starting their braces journey and I could not be happier with the results! The staff is incredibly kind, patient and most importantly, professional in every way. They are truly putting my children's needs/experience ahead of just turning a profit. Highly recommend!

Response from the owner:Thank you so much for sharing this, Alli! We’re thrilled to hear you’ve had such a positive experience with our team and our office. Taking care of our patients’ needs always comes first, and it means a lot that you noticed. Thank you for trusting us with their care and for recommending us. We truly appreciate it!

Michaela B.

What an amazing first appointment. Such a kind staff. Very understanding of all of our questions as well as our very distracting 2 younger children who wanted to play the whole time.

Response from the owner:Thank you for your wonderful review, Michaela! We're thrilled to hear that you had an amazing first appointment and that our staff was able to accommodate your family's needs. We look forward to seeing you and your children again soon!
