Jassy Casella Timberlake, M.Ed., LMFT, CST
Director and Founder, Northampton Sex Therapy Associates, LLC
With all my experience, both professionally and personally, I am struck by Jassy’s unique ability to balance challenge and support; to be fully present and compassionate while encouraging deep reflection and soul searching; to guide without directing. She very naturally creates an atmosphere of safety where even the most painful emotions or awkward issues can be touched, explored, penetrated…perhaps just spoken for the first time. She has an uncanny ability to strip through distractions and diversions to elicit the essential truth.

From the beginning of my sex therapy career, I realized the overwhelming need for certified sex therapists. I am motivated by my passions for social justice and for spreading body love—and self-acceptance—with a desire to educate people about sex and bodies, and to assist them in learning, healing, and growing into the sexual life of their choice. I see sex through a more complex lens than just a series of behaviors and techniques, understanding that sex is far from just being something that we do, but is more about the rich and complicated meanings that we make out of the things that arouse and excite us.
My identity is strongly rooted in Wales, the land where I was born. A Welsh heritage of story-telling, music and song strongly influences my identity as a therapist - in sessions clients have read me their poetry, played their instruments, and sung to me when words have failed them. While I have lived in the USA since 1984, I have held on to these values, which have helped to keep me grounded and focused on all the ways that people express their thoughts and feelings, not just with words. I have a passionate interest in social justice and sustainable communities.
I am licensed with the Commonwealth of Massachusetts as a marriage and family therapist, Lic. #1259, and my credentials can be verified with The Board of Registration of Allied Mental Health Providers.

Jassy Casella Timberlake has the critical skills of a trained professional. This entails taking a specific and detailed medical and psychological history of her clients that she keeps at her fingertips throughout each session and refers to them as needed. This professionalism is perfectly balanced by her empathy for her clients; it is palpable, and is an important part of her skills. As a client, I was never in doubt whether Jassy knew what I was feeling. Her skills in directing her clients through the minefields of their therapy are evident as she guides them in careful steps. She is flexible in her treatments, and has an extensive palette of therapies to draw from, none of which she relies on exclusively. This allows her a depth and flexibility of treatment that bodes well for her clients' progress. Her language and directions are always crystal clear, as are her boundaries as a therapist. She keeps her promises and guides her clients gently, yet firmly.
