Marianne Wiens, Psychotherapist

About Marianne

I am a Registered Clinical Social Worker specializing in Intensive Short-Term Dynamic Psychotherapy (ISTDP). My work is informed by over 13 years of clinical practice and a deep commitment to emotional growth and healing. I was first introduced to ISTDP 18 years ago through my own therapy—an experience that deeply shaped both my personal growth and my professional path.

For more than 20 years, I worked as a professional violinist. Performing at a high level taught me discipline, focus, and a deep sensitivity to human emotion—skills I bring to my therapeutic work.

I completed an IEDTA-certified core training program in ISTDP with Jon Frederickson, MSW, followed by advanced training with Jon Frederickson and Patricia Coughlin, PhD. I remain committed to ongoing professional development through supervision, consultation, and advanced training.

My practice is also grounded in my own ongoing inner work and personal development, which continually inform and strengthen my work with clients.

Beyond my work, I find balance and renewal in family life, walks and runs in nature, and in exploring and connecting with the deeper, spiritual essence of who we are.

My Approach

My approach draws on years of training and experience, grounded in evidence-based research. My therapeutic style is direct, empathic, and focused. I help clients recognize and work through the internal barriers that contribute to suffering, creating the conditions for greater clarity, authenticity, and connection.

Issues I Help With

I work with adults experiencing a range of emotional and relational challenges, including anxiety, depression, relationship difficulties, grief and loss, trauma, and functional neurological disorder (FND) and other somatic symptoms, which often relate to emotional blocks. Using ISTDP, I help clients work through defenses, access and process underlying emotions, resolve symptoms, and create meaningful, lasting change in their lives.
