Trauma therapy and PTSD treatment in San Francisco, by a psychiatrist trained where it's most severe.

I treat trauma and PTSD at my San Francisco practice, serve clients throughout the Bay Area, and offer telehealth across California. Trauma doesn't live in the event. It lives in the nervous system — in how your body responds long after the danger has passed. I've spent my career working with the full spectrum of trauma, from combat veterans to survivors of childhood abuse, and bring both the clinical expertise and the human presence to meet you where you are. About half of all U.S. adults will experience at least one traumatic event in their lives, and approximately 6% will develop PTSD at some point — with women affected at roughly twice the rate of men (National Institute of Mental Health; VA National Center for PTSD).

What It Looks Like

Recognizing trauma
in your daily life.

Intrusive memories or flashbacks to the traumatic event

Nightmares or disturbed sleep that leaves you exhausted

Hypervigilance — always scanning for danger, even in safe situations

Emotional numbing or feeling detached from your own life

Avoiding people, places, or situations that remind you of the trauma

Exaggerated startle response to sounds or unexpected touch

Difficulty concentrating or feeling present in the moment

Persistent feelings of shame, guilt, or self-blame

Irritability, anger, or emotional outbursts that feel out of proportion

Why trauma is different
from other mental health conditions.

Most mental health conditions involve patterns of thought, mood, or behavior that have gone awry. Trauma is different: it's a wound. Something happened that the nervous system wasn't equipped to fully process, and the unprocessed residue gets stored — not as a memory in the conventional sense, but as a physiological state the body keeps returning to.

This is why people with PTSD don't simply "think about" the trauma — they re-experience it. A smell, a sound, a certain quality of light triggers a full-body response that bypasses rational thought entirely. Understanding this distinction changes how treatment is approached. Among adults with PTSD, more than a third experience serious functional impairment — difficulty maintaining work, relationships, and daily life — underscoring why specialized, evidence-based treatment is essential (National Institute of Mental Health).

"Trauma is not what happens to you. It's what happens inside you as a result of what happened to you." The distinction matters enormously in how we treat it.

Where this comes from.

My residency at Tripler Army Medical Center — the only civilian on a military psychiatric program — was an intensive education in the most complex presentations of PTSD, working alongside active-duty service members. That training shaped how I treat trauma in every patient since.

I've trained extensively in two evidence-based trauma treatments that don't require detailed verbal retelling of the traumatic event:

Both modalities can produce significant results without requiring you to narrate the trauma in detail. The work happens at the level of the nervous system, not just the story.

What treatment looks like.

I don't separate the therapeutic work from the medication management. If medication is appropriate — and for trauma, that sometimes means addressing the hyperarousal and sleep disruption that make deeper processing impossible — I handle both myself, within the same ongoing relationship.

The first step is always understanding the whole picture: when the trauma occurred, how it has shaped your patterns and relationships, what has and hasn't helped in the past. From there, I build a treatment plan that matches your specific situation — not a protocol applied uniformly to everyone with a PTSD diagnosis.

My approach is fundamentally optimistic. The brain retains neuroplasticity throughout life, and there is now compelling evidence that trauma — even severe, longstanding trauma — can be meaningfully processed and resolved. I've seen this in patients who had lived with PTSD for decades. Recovery is not guaranteed, but it is genuinely possible.

Who this is right for.

My practice is well-suited for adults dealing with a range of traumatic experiences: combat or military service, sexual assault or abuse, childhood developmental trauma, accidents, medical trauma, sudden loss, or chronic interpersonal trauma. It's less suited for individuals in acute crisis requiring inpatient stabilization — if that's where you are, I can help you find the right level of care.

The past shaped you.
It doesn't have to define you.

Questions

Common questions

PTSD typically follows a specific traumatic event or series of events. Complex PTSD develops from prolonged, repeated trauma — often interpersonal, such as childhood abuse or domestic violence. C-PTSD tends to involve deeper disruptions to identity, relationships, and emotional regulation. Dr. Chacko treats both, though the approach and timeline differ.
EMDR (Eye Movement Desensitization and Reprocessing) helps the brain process traumatic memories that have become "stuck." During sessions, you briefly focus on a distressing memory while following a side-to-side stimulus. This bilateral stimulation helps the brain reprocess the memory so it no longer triggers the same intensity of distress.
No. Techniques like EMDR and Accelerated Resolution Therapy can produce meaningful results without requiring a detailed verbal account of the traumatic experience. Dr. Chacko will work at the pace that feels right for you, and you're in control of how much you share.
It varies significantly. Some people notice meaningful change within weeks; others work through trauma over months or years, particularly with complex or developmental trauma. Dr. Chacko will give you a realistic picture of what to expect based on your specific situation — not a promise of a quick fix.
Yes. Dr. Chacko is a psychiatrist who can both prescribe and conduct therapy himself. In some cases, medication helps create the stability needed for trauma processing. In others, therapy alone is sufficient. He'll assess what's right for you within the same ongoing relationship.
