Absolutely the best orthodontist!
The team here is incredibly professional, caring, and attentive. You can really tell they put their patients first and take pride in their work.

Highly recommend to anyone looking for top-notch orthodontic care!

Gabriela P.
My 3 kids have been patient of Dr. So she does an amazing job at creating beautiful smiles, my 19 year Old daughter first became a patient of Dr. So when she was around 10 years old for the first stage of her Ortho treatment, and of course she came back for her second stage for finalizing a beautiful smile. Of course I didn’t hesitate to bring my second child, then my third child. I would highly recommend her to anyone.
Response from the owner:Thank you for your wonderful review! We're thrilled to hear that Dr. So has created beautiful smiles for your children. Your recommendation means a lot to us. We look forward to continuing to serve your family!

Thuan D.
I highly recommend Dr. So and the team at CV Orthodontics for their outstanding service and care. From my initial consultation to creating a personalized treatment and payment plan, every step was seamless and stress-free.

After visiting several orthodontic offices, I'm glad I chose Dr. So's team. They consistently demonstrated exceptional courtesy and attentiveness to my needs, making me feel valued and supported throughout my journey.

Natacha J.
Dr So’s office is really efficient. I appreciate the text reminders, the self-check in and the welcoming atmosphere. Even though there are a lot of assistants on deck (I am basing this assumption on the youthful appearance of the employees), she always makes a point to avail herself when necessary.

The office is closed on Friday. While inconvenient, I appreciate the commitment to work/life balance.
Response from the owner:Thank you for your kind words! Your vote of confidence in our practice is why we do what we do!
Daisy Parra S.
Everyone in the office was very polite and informative since our very first appointment. The dental assistants did an excellent job in explaining everything to my daughter She walked out of the office with a smile A very pleasant experience Thank You
Response from the owner:Thank you for your wonderful review, Daisy! We are thrilled to hear that you and your daughter had a pleasant experience with our team. Our goal is to make every visit positive and informative. We appreciate your kind words!
Phuong V.
I recently completed my orthodontic treatment with Dr. So Orthodontic. I wanted to share my experience and why I think Dr. So is an exceptional choice for anyone considering orthodontic treatment.

From the very first consultation, I was impressed by Dr. So’s approach. Orthodontic treatment can feel daunting, but their gentleness and patient care stood out immediately. Dr. So took the time to explain all my options in detail, making sure I understood each step of the process. This level of care and communication was consistent throughout my treatment.

What truly sets Dr. So apart is their profound knowledge and expertise. They're not just about straightening teeth, they take a comprehensive approach to orthodontics, considering facial aesthetics, jaw alignment, and most of all your overall looks. It was clear to me that I was in the hands of a professional who is deeply passionate about delivering the best outcomes for their patients.

My results speak for themselves. I am thrilled with the transformation and the confidence my new smile has given me. But beyond the results, it was the journey that made my experience so positive. Knowing I was in gentle and knowledgeable hands made all the difference.

If you're looking for an orthodontist who combines expert care with a compassionate approach, I highly recommend Dr. So. They have not only transformed my smile but made the entire process a truly positive experience. Thank you, Dr. So, and all of your wonderful staff for the exceptional care and for giving me a smile that I'm proud to show off.
Response from the owner:Thank you so for your amazing review! We are so excited about your new smile and so happy that the journey was a pleasant experience!
L
Dr. So is absolutely amazing! Before deciding on CV Orthodontics, I consulted with a few other places. None of them were as comprehensive as Dr. So. They were just going to straighten my teeth, whereas Dr. So has designed a lovely smile like an artist! She is a consummate professional and warm. I look forward to my monthly visits. I highly recommend her!
-L. Chaney
Response from the owner:Thank you so much for the outstanding review! We love to be part of your journey to a beautiful smile!
Mocha B.
This has been the most phenomenal experience for me. I was sentenced to 2 years of wearing braces and there were ups and downs with getting adjusted, however Dr. So and her amazing team has been really good to me. They reassured me that everything would be fine and I was in good hands. I trusted their judgment and what they suggested would be best for me. The day to get my braces removed was rewarding and my teeth look BOMB! Dr. So did that and I’m so happy with the final results and couldn’t be happier! I would recommend Castro Valley Orthodontics to any and everyone who are in need of braces !
Response from the owner:Thank you so much! Sooooo excited about your beautiful new smile. It was a pleasure to be a part of your braces journey! - Dr So
Paulina Del R.
As a dentist, there is no one else I would trust with my own child's teeth than Dr. So. She is hands down the best!
Response from the owner:Thank you Dr Del Rio! It’s our pleasure to have your wonderful kids in our practice!
oliver L.
Dr. So is super friendly and have many years of experiences.
Response from the owner:Thank you so much for your thoughtful review. We appreciate the positive feedback- it means so much to us. We hope to continue to serve you and your family in the best way possible. Dr. So
Bree S.
The team and Dr. So are amazing. They explain a plan each appointment. Very attentive team.
Response from the owner:We love to hear great reviews about our office. Thank you for the positive review for being such a great patient! We appreciate you!
