Northampton Sex Therapy Associates (NSTA) provides research-based sex and relationship therapy, sexuality counseling and education to individuals, couples and poly/non-monogamous relationships.  We provide services to people of all sexual and gender identities, orientations, and lifestyles. We are a team of highly-trained clinicians and sexuality educators who conduct our work in an environment that uses social justice as one of our primary philosophies.  Our core values are to treat everybody with dignity, respect and compassion, seeing consent as the cornerstone for all relationships.

  “We are accepting and non­judgmental about the entire range of sexual behavior and sexuality.”

NSTA therapists are dedicated to the idea that everybody deserves to have a vibrant and passionate sexual life in a body that is accepted, loved and valued, regardless of age, size, color, social class, sexual orientation, relationship formation, gender identity or physical ability. That means all therapists at NSTA are accepting and nonjudgmental about the entire range of sexual behavior and sexuality. We recognize the importance of being fully present in our bodies and believe that our clients deserve to experience that for themselves.  NSTA is the only group private practice in New England dedicated exclusively to providing sex therapy and sexuality counseling to couples, people in poly relationships and individuals.  Located in the Pioneer Valley of Western Massachusetts, our clients travel here from the Berkshires, Eastern and Central Massachusetts -  as well as New York, Connecticut, New Hampshire and Vermont.
