The treatment, in plain terms
What actually happens during a TMS session.
It's quieter than most people expect. You sit upright in a comfortable chair, fully awake, with a small device positioned near your head. No anesthesia, no hospital gown, no recovery room.
You sit in a chair, fully clothed, fully awake.
The coil is positioned over the left dorsolateral prefrontal cortex. Most patients read, listen to music, or rest.
Brief magnetic pulses, painlessly delivered.
The pulses pass through the scalp and stimulate underactive neurons in cortico-limbic networks implicated in depression. You'll feel a tapping sensation. No medication, no anesthesia.
About 20 minutes per session.
Five days a week, for six weeks. You drive yourself to and from the appointment. Most return to work the same day.
Results build over the course.
Patients who respond typically notice changes between weeks 3 and 6 — better sleep, restored interest, a quieter inner voice.

Questions from Chino Hills patients
Frequently asked questions.
What conditions does TMS therapy treat?
At Healing TMS Clinic, Transcranial Magnetic Stimulation (TMS) is used for treatment-resistant depression, obsessive-compulsive disorder (OCD), and anxious depression — FDA-cleared indications for patients who haven't gotten enough relief from medication alone.
Is TMS therapy the same as ECT or "shock therapy"?
No. TMS uses focused magnetic pulses while you sit awake in a chair — there is no anesthesia, no sedation, and no effect on memory. It is a different treatment from ECT.
Is TMS therapy safe, and what are the side effects?
TMS is non-invasive and generally well tolerated. The most common side effects are mild scalp discomfort or a short-lived headache near the treatment area, which usually ease within the first week. You stay awake throughout and drive yourself home. Serious side effects are uncommon, and Dr. Shamasundara reviews your history first to confirm TMS is appropriate for you.
Is TMS therapy painful, and is there any downtime?
No. You stay awake the entire time — there's no anesthesia and no sedation — and you drive yourself home afterward. Most people return to their normal day right after a session.
Can I keep taking my medications during TMS therapy?
In most cases, yes — many patients continue their current medications during a TMS course. Dr. Shamasundara reviews your full medication list at the consultation and will tell you if anything should change.
Does insurance cover TMS therapy for Chino Hills patients?
For most plans, TMS is a covered treatment for treatment-resistant depression. We verify your specific benefits — including any prior-authorization requirement — and tell you your out-of-pocket cost before you commit. The fastest way to start is our insurance verification form.
What if my insurance doesn't cover TMS therapy?
We'll tell you before you commit. If TMS isn't covered under your plan, we'll walk through your options and any out-of-pocket cost up front — no surprises.
Do I need a referral, and how do I know if I'm a candidate?
You don't need a referral to reach out. The best first step is our short TMS candidacy questionnaire, or a quick call — we'll review what you've already tried and whether TMS is a good fit for you.
