EMDR is a therapeutic approach, where the perspective is about the past, present, and the future.  The therapist works collaboratively with the client to identify current symptoms, past memories (trauma) to desensitize.  Rapid eye movements allow that to happen.  And lastly, looking at how the person can feel more confident in the future.

Mindfulness is derived by the buddhist teachings.  Learning to be in the present, without judgement.  This helps in managing thoughts, emotions, actions.  Also, mindfulness works together with EMDR. 

I run a mindfulness group once a week. Also, I practice this in individual sessions.

DBT is Dialect Behavior Therapy, which is focused on the present.  It includes 4 skill sets:

communication skills, mindfulness, emotion regulation, and distress tolerance. The skills can always be useful in conjunction with EMDR.
