Why a phone-audit grade?
Reviews tell you about the chair. They rarely tell you what happens when you call at 9 p.m. because a bracket is poking your child's cheek. We test that part, the same way every time, so you can compare offices on it.
How we grade Santa Clarita orthodontists
Best Ortho places mystery-shopper calls to orthodontist offices after hours and grades the greeting a patient actually hears, from A+ to F.
- Calls run between 10 p.m. and 4 a.m. Mountain Time.
- A call is graded on whether the greeting names the practice, gives hours or a clear next step, and offers an emergency path. See the full scale on our methodology page.
- Calls that never connect (no answer, busy, failed) are left ungraded. They are not scored as a failure.
What the grades mean (and what they do not)
| Grade | What the caller heard |
|---|---|
| A+ | The practice is named, hours or a next step are given, and there is an emergency path |
| A | The practice is named, with hours or a callback offered (or a live answering service that identifies the practice) |
| A- | The practice is named, but the next step is limited |
| B+ | A generic but clear practice mailbox |
| C+ to C- | An unnamed or generic mailbox, almost no greeting, or unintelligible audio |
| D | The call reaches a different business than the one listed |
| F | The line is disconnected, the mailbox is not set up, or there is no working office number |
A grade measures the after-hours phone experience. It does not measure clinical skill. Use it as one signal alongside consultations, credentials and reviews.
What a Santa Clarita patient can do with a grade
- Shortlist two or three offices from the top of the list.
- Book a consultation at each, and ask what to do if something breaks after hours.
- Treat the grade as one signal. It measures the phone experience, not clinical skill.

Frequently asked questions
Who is the best orthodontist in Santa Clarita?
There is no single best orthodontist for everyone. Best Ortho grades Santa Clarita practices on after-hours phone handling, and the top-graded offices are listed at the top of this page. Book consultations with two or three before you decide.
How does Best Ortho grade orthodontists?
We place mystery-shopper phone calls after hours and grade the greeting from A+ to F. The grade reflects whether the practice is named, whether hours or a next step are given, and whether there is an emergency path.
Does an A+ mean the best orthodontic care?
No. An A+ means the after-hours phone experience was excellent. It does not measure treatment outcomes or clinical skill, so use it alongside consultations and credentials.
Why is my orthodontist not graded?
Some calls do not connect (no answer, busy, or a failed call), and those are left ungraded rather than scored as a failure. 11 of 13 Santa Clarita offices have a grade today.
