Whether the result of routine family and relationship changes, or the distress of life-changing events … sexual rupture is prevalent, and it’s pushing partners away from each other.

As therapists, you have the opportunity to help clients discover fulfilling and exciting relationships again – both physically and emotionally.

But you need the right training to be effective!

Sex and relationships are constantly changing, and our field has been way behind the curve. That’s why we’re excited to announce that enrollment is open for this sex therapy certification training that provides the cutting-edge, real-life information every therapist needs to confidently work with sex and intimate relationships.
