Our Team

The sex therapists at the U-M Center for Sexual Health are licensed mental health professionals who have received specialized training in helping people resolve sexual difficulties through counseling. Sex therapists counsel individuals or couples and teach sexuality education, as well as communication and stress reduction techniques. They also give specific information to help resolve sexual problems. No sexual activity is ever practiced in the therapist’s office. Sex therapists listen and talk to you, and help you find ways to overcome or adjust to your problems.

Sex therapists at the University of Michigan Health Systems are required to hold the specialized national certification called “AASECT certified” sex therapy. You will either see a certified sex therapist or a sex therapist who is finalizing their certification in sex therapy. U-M sex therapists are also engaged in teaching sexuality education to faculty and graduate students, and are committed to better standards for providing information about sexual health to patients and clients at the University of Michigan and its clinics.

Sex Therapist Certification

For the great majority of professionals in health care and human services, sex therapist certification is a prerequisite to independent practice as a sex therapist. It is important to know that there is a national credentialing body called the American Association of Sexuality Educators, Counselors and Therapists.  AASECT credentials sexual health professionals on the basis of rigorous standards for academic preparation, supervised training and consultation, field-related experience and applied skills. Certification by AASECT is a crucial step in professional stature, demonstrating to all that the sex therapist has met stringent requirements for training and experience.
