Who we are
The Institute was created to meet a need generated by a significant deficit in the training of psychotherapists, physicians and clergy. Most providers have little to no training in sexual health. Yet sexuality is core to intimacy. In addition, sex therapists have little to no training in couple’s therapy. Yet relational dynamics effect the sexual relationship. This deficit left the public seeing uninformed providers.
The goal of the Northwest Institute on Intimacy is to make it standard of care that all people seeking psychotherapy can expect to see someone with expert training and supervision in individual, couple, sex and spiritual intimacy therapy. We believe that no matter what issue a client is presenting, whether relational, sexual, historical, circumstantial, intrapersonal or other, the therapist needs to be adept at assessment, diagnosis and treatment without a lack of training or self-of-the-therapist issue interfering with their care.
Educate various clinicians and other educators on how to share the value of diverse expressions of healthy sexuality by providing world-class courses, supervision, and tools.
Provide the public with access to impactful resources on healthy sexuality.
The board's vision and charter: We want to see a world in which all people are sexually healthy, knowing how to create the level of connection and pleasure they desire. Educators and clinicians have the knowledge and competence to teach sexual health and intimacy well, and all people recognize the role sexuality plays into our overall health and wellness. They understand the value of healthy sexuality and treat it that way.
