What Sets Us Apart


Castro Valley Orthodontics is a full-service specialty practice engaged exclusively in orthodontics. To put it simply, we specialize in making you smile!

A Philosophy Based on Trust

We treat our patient as individuals, caring about their individual needs by listening and understanding what their expectations are, and then exceeding them in the service we provide. We are closely connected to our patients and take great care of them from beginning to end. We want what is best for our patients and do so ethically and responsibly. 

An Orthodontist Committed to Excellence

Dr. Susan So is a board-certified specialist in orthodontics: In addition to completing specialty training in an accredited program (Harvard University), she has reached the highest level of proficiency in her field. She goes the extra mile to make sure her patients’ results are nothing short of excellent!

A Focus on Education

Everyone has a different perspective—some patients know what it is like to have braces, some don’t. We don’t assume that everyone understands the process. We patiently explain our procedures and answer all questions. We also encourage parents to come to their children’s appointments and ask questions, get updates, and understand what is going on with their child’s care.

An Awesome Environment

We want you to look forward to your appointments and have a positive experience every time you come to see us, which is why we’ve designed an office that is as fun as it is professional. For our young patients, we offer portable video games, in addition to family-friendly movies for siblings to enjoy in the reception area. Plus, we host an annual ice cream social for patient appreciation with prizes, face painting, and henna!

A Dedication to Technology

We utilize the highest quality materials and most modern techniques, including advanced treatment methods with Invisalign® and ClearCorrect™, and diagnostics with digital X-rays and 3D scanning for the best possible outcomes.

A Convenient Experience

We understand that our patients’ time is as important as ours, which is why we try to stay on schedule and accommodate our patients’ busy lives. We offer early-morning appointments Tuesdays and Wednesdays, in addition to our regular after-school hours for patients’ convenience. Additionally, our Patient Login allows patients to pay bills, check appointments, and even register to receive text, phone, or email reminders for appointments.
