Mari Matsumura

Certified Clinical Psychologist & Certified Public Psychologist
Somatic Experiencing® Practitioner (SEP)

Mari is a certified psychotherapist in Japan, specializing in trauma, dissociation, and somatic approaches. Her clinical journey began in 2001, working with teenagers and children in a child welfare setting.

Her own lived experience with complex trauma became a catalyst for her healing journey, leading to over two decades of dedicated training and education. With more than 24 years of experience in clinical settings and school counseling, she continues to deepen her own healing while supporting clients in reclaiming their innate power and resilience.

Mari believes that regardless of your past or current challenges, it is possible to live a fulfilling life as your authentic self. She helps clients access their internal resources and strengths by processing experiences through breath, somatic sensation, sound, imagery, and movement.
