Child, teen, and adult psychiatrist. Menlo Park and telehealth across California.

Good treatment starts with getting the diagnosis right.

I’m Earth Hasassri, MD, board-certified in adult and child & adolescent psychiatry (Mayo Clinic, UCSF, Stanford). As a physician, I do a full clinical evaluation before anything else, because medical problems often masquerade as psychiatric ones and the treatment only works if the diagnosis is right. From there we build the plan together: talk therapy, medication when it’s indicated, or a single-day TMS protocol when depression, anxiety, or OCD hasn’t responded to other treatments.

What I can help with

ADHD, autism, and neurodevelopmental differences

Full clinical evaluations, not checklist visits, with ongoing medical management.

Anxiety, depression, and OCD

In kids, teens, and adults. Careful diagnosis first, then therapy, medication, or both, decided together.

Complex and treatment-resistant cases

Medical workup including labs when warranted, coordination with your other physicians, and single-day TMS when appropriate.

How starting works

  1. A free, brief phone call

    You tell me what’s going on and we see if I’m a good fit.

  2. A comprehensive clinical evaluation

    Ninety minutes, full history and medical review, and a clear diagnosis.

  3. Then we agree on a treatment plan together

    Therapy, medication, lifestyle changes, or a combination, based on what the evaluation shows.
