Two rooms. One read on the body.

For almost thirty years, Diane has worked in two rooms.

On the mat, she reads bodies under live pressure. Timing, distance, the tell before the throw.

On the table, she reads what those same bodies carry into everyday life. Where load is being held. Where the spine and fascia have stopped moving. Where an old alarm is still running long after the threat is gone.

Most practitioners work in one of those rooms. Diane works in both, and that read is what her clients come for.

ON THE MAT

Kaiden Shihan Kogyoku, 5th Dan, KoKoDo JuJutsu. One of two women in the world to hold the rank of Kogyoku, and the first female to receive this outside Japan.

Co-owner of Sadohana with Sohanshi Michael Seamark, and Shomubucho (general manager) of KoKoDo JuJutsu Sadohana-kai.

Blue belt in Brazilian Jiu-Jitsu. Still getting tapped, and that's the point.

ON THE TABLE

Yoga therapist since 1997. Her sessions focus on spine health, fascia and tissue hydration. She reads the stress patterns in your body, then builds modified isometric movement into everyday motion, so the change leaves the room with you.

Every session works across four kinds of habit: physical, emotional, mental and spiritual.

Former in-house yoga therapist for CBC and the Labour Relations Board of BC. Former nursing assistant. Certified Meditation Teacher and certified BodyMind Coach. Her work is trauma-informed and draws on somatic experiencing.
