About the Director

"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."

On a personal note:
Jassy is Welsh, born in Swansea, South Wales, UK - she moved to the USA in 1984.  She has a passionate interest in sustainable communities and Peak Oil, and enjoys walking, reading, playing music really loudly, spending time with friends and family, and playing the piano less often than she would like.

"Jassy 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." T.B. (JP, MA)
