About us

Artisa is co-founded and managed by Celeste Neelen. She works together with committed and skillful colleagues. We share a passion for a life long learning, writing, art, creating, sun and spiritual development. Our strength lies in our individual expertise and the added value of our cooperation.

Director Artisa Celeste Celeste Neelen graduated as work and organizational psychologist at Radboud University Nijmegen and modern dance teacher at Amsterdam School of the Arts. She has been running her own company, for many years, specializing in personal and spiritual development and  leadership.
She is co-founder of La Terra Saggia, director of ARTISA and partner of Quinx, a Belgian-Dutch consultancy company. She is an experienced coach of (silent) retreats. Bringing people into contact with their innate qualities and freedom and encouraging them to put their potential into action, is what she loves to do.
In the spare time that is left she works as a visual artist, creating paintings in oil and mixed media: colourful expressions of movement, light, and space.

Misja GoossensMisja Goossens graduated as Master of Arts at the Utrecht University. She migrated to Berlin in 2007 to work in international, traveling projects where art was used as a tool for personal development and intercultural understanding and dialogue. In 2014 she became a mother and similarly followed a 3,5 years course for systemic work in family- and organizational context.
She loves to create space beyond judgement. Deeply knowing and feeling that the embracement of the whole you, also the unwelcome and ugly parts that we all have, paves the way for real change and re-connection with your inner source.
She uses elements of systemic work, impro-theatre, yoga, dance, breath work, silence and authentic talk, to take you on a journey for less masks and more you. She co-facilitates our time-out program.
