Why Combine Attachment & Sex Therapy?

Attachment Styles & Sexual Scripts
Learn how anxious, avoidant, and disorganized attachment patterns show up sexually.
Intimacy, Rupture & Repair
Explore how couples move through conflict to deeper erotic connection.
Desire, Arousal & Emotional Safety
Support clients in creating secure and satisfying erotic lives.
SAR & Tools for Individuals & Couples
Interventions rooted in EFT, trauma-informed practice, and somatic awareness.

Michael Moran, LCSW, CST-S is the Founder and Director of The Center for Relational Fulfillment in New York, NY where he specializes at the intersection of relational and sexual challenges. He is a Certified Emotionally Focused Couple Therapist (EFT) & Supervisor as well as an AASECT Certified Sex Therapist and Supervisor. He was Sr. Faculty in the Sex Therapy division at The Institute for Contemporary Psychotherapy (ICP), has taught graduate courses in Marriage and Family therapy and LGBTQ Issues in Contemporary Society at Rutgers University and was interviewed by Esther Perel on her “Sessions” platform on the integration of EFT and sex therapy.

His website is www.fulfilledcouples.com.
Dr. Kimberly Castelo, LMFT, CST, PhD
Renowned clinician and educator specializing in trauma, queer-inclusive care, and attachment-based therapy.
Dr. Kimberly Castelo specializes in sex and attachment. Dr. Castelo is certified and is a supervisor in all the EFT modalities and as a Sex Therapist. She brings a wealth of experience, practical interventions and invaluable information about the power of attachment in sex therapy. Over the years she has heard sex therapists say – “I love attachment, but I am not sure how it fits into sex therapy” OR “I love attachment work, but not sure how to bring up sex!” Attachment theory joined with sex therapy can foster the secondary change we are hoping occurs with our clients regardless of their presenting concern! Kimberly will help you learn and thrive as you become a Certified Sex Attachment Therapist (CAST). Let’s begin to learn to hear the heart (attachment longing) of our clients.

Unique Qualifications of Modern Sex Therapy Institutes
“Sex therapy is an unregulated field in all states except Florida, which means many people who have licenses to practice therapy can call themselves sex therapists without formal training,” Dr. Needle states. “It is a good idea for clients to ask therapists about their training in sex and relationships when those are the issues they are coming in with” she notes.
Modern Sex Therapy Institutes has been offering Continuing Education (CE) and Sex Therapy Certification for over 15 years, providing the most flexible scheduling, course, and payment options in the market! With over 300 workshops to choose from, you can get all of your CE Hours for AASECT (American Association of Sexuality Educators, Counselors and Therapists) or your license in person in 8 states, online via live (Zoom) webinars, or via video recordings.
Modern Sex Therapy Institutes is an AASECT, APA, ASWB and NBCC approved CE provider and offers Certification in Sex Therapy, Counseling and Education, 18 other specialty certifications, a Ph.D. in Clinical Sexology, and Renewal CE Hours.
