How Long EMDR Therapy Takes: Understanding Your Timeline

You’re finally ready to face the past and move forward, but you’re wondering how long EMDR therapy actually takes. You’ve heard stories of people being in therapy for years and you don’t want that. How long is the commitment? What should you expect from the EMDR treatment timeline? Here’s a clear breakdown of how EMDR works—from your first session through reprocessing—so you can plan for meaningful, long-term relief.

Psychological Evaluation and EMDR Treatment Planning

Before I can answer how long EMDR therapy will last, I have to understand your personal history and treatment goals. On average, it takes me 1-2 sessions to complete a psychiatric interview. In this interview, I’m asking about your personal history as well as assessing your current symptoms. I’m also loosely creating a treatment plan as we go along. Once I’ve completed this interview, you and I will discuss your treatment goals. If there’s one memory that’s been bothering you and that’s all you want to work on, then that will take much less time than if there are multiple incidents to address. After we’ve finished the interview and decided on your treatment goals, I create a Master Treatment Plan and review it with you during our next session.

EMDR Preparation Sessions

Typically, by session three I’m handing you your Master Treatment Plan and we are reviewing it together. Here, I’m explaining to you how this plan will help you meet your treatment goals and you’re giving me feedback to ensure we’re on the same page. And of course, I adjust your plan based on our discussion!

After this, I spend the remainder of the session educating you and preparing you for EMDR. Typically, I describe trauma memory storage, the Adaptive Information Processing Model, how the process works and what to expect. I also explain the ranges of reactions I’ve seen over the years so you are prepared for for the EMDR experience. I invite you to ask questions and I even embrace skepticism! (Click here to learn why I changed my mind about EMDR). I want you to feel fully informed about EMDR therapy, with the risks and the benefits, so you can make a decision that feels comfortable for you!

Depending on the length of our discussion, we may even have time for some specific tools to prepare you for the emotional experience of EMDR therapy. On average, I typically spend 1-2 sessions with you where our focus is on developing and strengthening emotional management skills. For individuals who find that they dissociate a great deal, or have a lot of anxiety about addressing their past, we may need to spend more time on the preparation process. It’s important to remember that we are not in a race to get to EMDR reprocessing! The preparation phase in and of itself can be quite stabilizing. Most importantly, we’re setting your foundation so you can have the best experience during the reprocessing phase as possible.

How Long EMDR Reprocessing Usually Takes

Typically, by session five is when we actually start reprocessing particular targets from your Master Treatment Plan. From my experience, most targets take 1-3 EMDR sessions (my sessions are 50 minutes) to process. This doesn’t mean that every single target will land in that range. On occasion, I run into targets that take longer! The longest it’s taken me to process a target (so far) has been seven sessions.

When EMDR Preparation Takes Longer

For some people, the preparation phase of EMDR therapy can take longer than a session or two. When someone has experienced complex trauma, chronic childhood adversity, or significant dissociation, the nervous system may need more time to build stability before trauma processing begins.

In these situations, EMDR preparation might last several months, and occasionally longer. This doesn’t mean therapy is “stuck” or that EMDR isn’t working. In fact, the preparation phase is often where some of the most meaningful early progress occurs. Clients begin learning how to regulate emotions, recognize triggers, strengthen grounding skills, and develop a sense of internal safety before deeper trauma work begins.

When trauma has been present for many years, the brain and body have adapted to survive under difficult circumstances. Moving too quickly into trauma reprocessing can overwhelm the nervous system rather than support healing. Taking time to build stabilization skills helps ensure that when processing does begin, the experience is manageable and effective.

For clients with complex trauma histories, preparation may also include developing stronger internal resources, working with dissociative parts, or gradually increasing the nervous system’s ability to stay present while difficult material is activated. These steps help create the conditions needed for EMDR to work safely.

Although it can feel frustrating to move more slowly than expected, careful preparation often makes the later stages of EMDR more efficient and sustainable. The goal is not speed, it is setting you up for success with lasting change.

What to Expect From Your EMDR Timeline

So here’s where a little math gets involved. Let’s say you only have one life event you want to process. Well I can estimate that on average, that would take about eight sessions. Add 2-3 sessions per target and you’ve got a rough ballpark of how long EMDR therapy would take for you.

I have yet to have a client who had only one event they wanted to work on, but I can say that on average, my clients are with me for about six months. If someone has complex PTSD, that generally means we should do more preparation work before you begin processing and there are usually more clusters of targets we need to address. In those cases, you’re looking at several years. You might cringe when you think about committing to weekly treatment for that length of time! It’s important to remember that you are investing in yourself and your future. You are doing this for long term change - and once you are done with the process you will have wished you had started even sooner!
