Co-Leadership, Community and Innovation

NICE Institute is guided by Bert Stek and Evelien Bus, who bring a deep passion for Core Energetics, body-oriented psychotherapy, and personal development. Their approach is based on co-leadership, believing that true personal and professional growth happens in relationship — with each other and within the Core Energetics community.

Mission of NICE

The mission of the Netherlands Institute of Core Energetics (NICE) is to support the development of Core Energetics, grounded in our belief in the transformative power of personal growth for individuals and for the world. We are committed to building a thriving Core Energetics community of teachers, trainers, students, and alumni, where authenticity, vitality, and safety are core values. Our graduates, in turn, support others in their personal and professional development. Through this work, NICE aims to contribute to the collective evolution of humanity, helping people navigate the challenges of today’s world with awareness, connection, and resilience. NICE strives to create a safe, supportive environment where individuals can be vulnerable, authentic, and fully themselves.

Ethical Committee

The Ethical Committee plays a vital role in upholding NICE’s ethical standards and ensuring a safe, respectful environment for students, faculty, and clients. It provides guidance on complex situations, reviews complaints when needed, and meets annually for general review or on an ad-hoc basis. The committee operates independently and with full confidentiality, offering support with integrity and care. The EC is made up of three experienced Core Energetics professionals: Marcel Vos (Chair), Hana Hniličková, and Ceylan Kara, bringing a wealth of therapeutic, educational, and ethical expertise. Together, they ensure NICE maintains the highest ethical standards in all aspects of training and practice.

• Marcel Vos is a Core Energetics therapist, trainer, and coach in the Netherlands. He combines body-oriented therapy, coaching, and non-dual healing, supporting individuals with ADHD and Autism Spectrum Disorder, and is deeply committed to ethical practice.
• Hana Hniličková, based in Prague, integrates Core Energetics with personal and societal transformation. She focuses on restoring body connection and building inner resilience.
• Ceylan Kara is a trauma therapist, executive coach, and educator with international experience. She combines body-centered psychotherapy and trauma resolution with insights from her previous career in international law.

Exam Committee

The Exam Committee plays a crucial role in assessing and validating students in the professional training program. The committee consists of Piet Jan van Wier (chair), Cornelia Harz, Eline de Man, and Willie van Boven. All are Core Energetics therapists and bring a wealth of experience and expertise. They are all deeply committed to the work.
