Dr. Earth Hasassri offers the AMPA Health ONE-D protocol, a peer-reviewed, single-day TMS regimen delivering 20 iTBS sessions in 9.5 hours, with neuroplasticity-enhancing medication. No weeks of daily clinic visits. One day. Lasting results.
If you've tried antidepressants and they haven't worked, TMS offers something fundamentally different: it works directly on the brain circuits that depression disrupts, using focused magnetic pulses. No surgery, no anesthesia, nothing systemic. Just targeted stimulation of the region where depression lives.
Traditional TMS requires patients to return to the clinic 5 days a week for 4–6 weeks, which is a significant barrier for people with busy schedules, mobility challenges, or limited access to specialty care.
The AMPA Health ONE-D protocol delivers a full course of TMS in a single day, combining an accelerated stimulation schedule with medications that help the brain respond more deeply to treatment. Published in Transcranial Magnetic Stimulation (Vaughn et al., 2025), the results outperform conventional multi-week TMS — in a fraction of the time.
Your entire TMS course is completed in one day. You arrive in the morning, receive all 20 sessions in a comfortable setting, and leave the same evening with your treatment complete.
Both medications are used off-label as part of the ONE-D protocol and are not FDA-approved for this indication.

These are real outcomes from real patients: adults who had already tried medications and still weren't well. The results are tracked at 6, 12, and 26 weeks after a single treatment day. Not estimates. Not projections. Measured outcomes.
Depression has many treatment paths. The chart below shows how ONE-D compares to standard options, based on published clinical data. Response means a significant reduction in symptoms; remission means near or full recovery.
High response rates matter, but so does when relief arrives. Each dot below represents one day of your life spent waiting for treatment to work. For people suffering from depression, that wait is not abstract.
For adults who have struggled with depression through medication trials, or who cannot commit to weeks of daily clinic visits, ONE-D offers a transformative alternative: a full treatment course, done in a single day.
Dr. Hasassri provides age-adapted ONE-D care for adolescents. The single-day format means minimal school disruption and offers families a meaningful non-medication option during critical developmental years.
The AMPA Health TMS device is portable, allowing the complete ONE-D protocol to be delivered at your home, hotel, or another location of your choosing within the greater Bay Area. A travel fee applies, billed at Dr. Hasassri's hourly rate with a two-hour minimum, in addition to the standard program fee. Travel fees are confirmed prior to scheduling.

Dr. Hasassri's TMS expertise was built across his UCSF psychiatry residency and Stanford fellowship, with clinical training at TMS Health Solutions and research experience in Stanford's Brain Stimulation Lab under Dr. Nolan Williams, one of the world's foremost TMS researchers. During his fellowship he contributed to TMS research in both adult and pediatric populations, including studies on safety and on novel applications in autism spectrum disorder, and has presented at Stanford Child Psychiatry Grand Rounds. He is a member of the Clinical TMS Society and holds certification through its clinical workshop program.
