Leadership

Netherlands Institute of Core Energetics (NICE) was founded in 2005 by Anna Timmermans.

In 2023 NICE celebrated a transition of leadership. Anna Timmermans stepped out of individual leadership and we stepped into a collective one with an circle of six directors – Anna Timmermans, Bert Stek, Evelien Bus, Klaus Stinshoff, Nuno Salema and Riet Mellink (Riet till January 2025). The circle represented a new paradigm of leadership, each of the members bringing their own unique qualities, expressing a multitude of perspectives in the process of leading the institute.

In June 2025 Anna Timmermans stepped down as member of the circle. Her decision was announced with a heartfelt document of honor, recognizing her remarkable contributions to NICE. In September 2025 it became clear for Nuno as well as Klaus that the role of director did not fit for them anymore.

The team of directors now consists of Evelien Bus and Bert Stek. They carry forward the flame Anna lit.

The Netherlands Institute of Core Energetics is committed to support the development and expansion of Core Energetics by creating a thriving community of teachers, students and alumni that invest in their personal process and can support others in their individual and collective processes, facing the challenges the world is experiencing in our current times.

Bert Stek works as finance director for a construction company. Because this work mostly brings him ‘into his head’, he did the professional training from 2008 to 2012 with the intention to be able to integrate body, mind and feelings more.

Evelien Bus holds a Bachelor’s degree in Social Science, as well as Master’s degrees in Education and Mathematics. She graduated as a Core therapist in 2017. She has her private practice as a Core therapist and teaches in the NICE Professional Training Program. She loves to combine Core Energetics with more subtle energy work (sensing energy). Alongside her work with and for NICE she lectures in the teacher education program of the Amsterdam University of Applied Sciences.

Ethical Committee

The ethical committee (EC) has a key role in supporting the ethical foundation of our institute and ensuring a safe and respectful environment for students, faculty, and clients alike. The EC supports NICE in safeguarding ethical standards, advising on complex situations, and reviewing complaints when needed. It meets annually for general review and on an ad-hoc basis when specific cases arise. The committee operates independently and with full confidentiality, offering guidance with integrity and care.

The committee consists of three experienced professionals from the international Core Energetics community: Marcel Vos (Chair), Hana Hniličková, and Ceylan Kara. Together, they bring a wealth of therapeutic, educational, and ethical expertise to this important role.

Marcel Vos (chair) is a Core Energetics therapist, trainer, and group facilitator based in the Netherlands. With extensive experience in personal development, group dynamics, and ethical reflection, he brings grounded leadership to the EC. His professional background includes body-oriented therapy, co-active coaching and non-dual healing. Over the past five years, he has worked extensively as a life coach for individuals with ADHD and Autism Spectrum Disorder (ASS), alongside his work as a Core Energetics therapist in his own practice. Marcel is deeply committed to ethical practice and passionate about fostering transparency and accountability in therapeutic work. More about his work can be found at www.marcelvos.info.

Hana Hniličková is based in Prague, where she runs a thriving practice under the name CORE Therapy: www.coretherapy.cz. She is trained in Core Energetics at NICE and works for the Institute of Core Energetics Greece as an assistant.  She integrates her work with a deep commitment to personal and societal transformation. Hana focuses on restoring connection with the body and building inner resilience, and brings a grounded, compassionate presence to the committee.

Ceylan Kara is a complex developmental trauma therapist, executive coach, and educator committed to cultivating a global network of conscious women in leadership. She supports clients internationally through online programs and in-person deep dive retreats. Prior to entering the healing profession, Ceylan was a mergers & acquisitions partner at a top-tier international law firm. Her current work draws on the discernment and clarity developed in her legal career, alongside extensive training in body-centered psychotherapy, trauma resolution, and spiritual inquiry. With over a decade of interdisciplinary experience, she brings a thoughtful, grounded perspective to ethical questions in therapeutic practice.
