Dr. Stephen M.
Best service and really accommodating. Took care of all my needs. Appreciate all you guys
DAVE W.
Three years ago, I was diagnosed with severe sleep apnea caused by jaw and tongue displacement. After researching orthodontists in my area, I found Castro Valley Orthodontics and began treatment with Dr. Susan So. From the beginning, Dr. So created a detailed treatment plan and guided me through every stage of the process, including surgery preparation and recovery. Her professionalism, communication, and attention to detail are exceptional. The results have been life-changing — I look and feel like a completely different person. At this point, just give this doctor your money and change your life. Honestly, my jawline showed up before some of my friends did. I highly recommend Dr. Susan So to anyone looking for a trustworthy and truly dedicated orthodontist.
Cameron B.
I just started my treatment. The Orthodontists and staff were very knowledgeable and gave me a good understanding of what was required.
Cassandra Swiney N.
Dr. So and her team wonderful. They are knowledgeable with state of the art equipment. It’s a welcoming and comfortable environment.
MQ N.
Amazing staff and welcoming environment. Getting aligners and situated here has been an amazing experience. I am happy that I chose to go with this team to get my teeth straightened. Many thanks to the Dr. and her staff!
Elizabeth P.
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. What I love the most is how efficient they are — the appointments are always quick, yet thorough. I never feel rushed, but I’m always in and out in no time. Highly recommend to anyone looking for top-notch orthodontic care!
Tammie B.
Staff is friendly. Everything is well explained. My child feels comfortable there.
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.

We have had a great experience with the staff at Castro Valley Orthodontics.
Mel S.
Simply the best. Kind, efficient, helpful and so very knowledgeable. My whole family has been there for treatment. Highly recommend.
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.
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
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.

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
