Welcome to my website.

I have a quite versatile way of working and living. I love creating things, playing with tech and also to do meditation, breathwork and deeper inner work. A part of my work is in the field of IT, where I enjoy diving deep into technical structures. Lately I’m focusing on networks and datacenter on premise. I am a father of two teenagers, co-parenting.

And I like to make drawings in Mermaid :)

About me

img img

I was born in Almelo at the beginning of 1967.

As a child I was living at several places; our family was moving around a lot. I have an older brother and a younger sister. In the mid 70’s we moved to the region of Leiden in the Netherlands, where I’m currenlty still residing.

My background is paramedical, I studied physical therapy and occupational therapy.

Then, a tat late some would say, I started to play with technical stuff, computers and networks. Evolving projects like Wireless Leiden, Open Community Camp and most lately, MakerSpace Leiden.

From a retrospective, I’ve alway been involved with tech and people; getting things organized and realized.

The last 20 years I’m spending of lot of time exploring other sides of humanity, or more exact exploring the inside world.

Sometimes I also organise small events around meditation and Self-exploration.

I have been spending quite some time in personal and spiritual development over the last decades.

In 2020 I attended to a training at the “In de Smeltkroes” bij Viram Verberk and Marie le Mahieu, assisted by Anne Langedijk.

This training “Innnerlijke Stemmen Innerlijke Leiding” (Inner Voices Inner Leading) is an introduction to the IFS (Internal Family Systems).

After this introduction I got inspirired to learn and play with IFS. I attended to several online trainings and in 2023 the Level 1 training.

IFS focusses on including all parts, their relation, cooperation and befriending. And there is one part, called Self, that considdered to be something else capable connecting and leading the parts.

In the training I learned to work with those parts, and I love working with them.

Curious? drop me an email… (Sessions on workdays are mostly on Monday)

The sessions are in English (second language) en Dutch.

The session can face tot face in Leiden, the Netherland or via internet (Zoom/Signal/Whatsapp/Jitsi).

Prices for sessions: 85 euro per hour (May 2023).

Available timezones

  • ETC/CET :: 09:00 to 17:00 (and some evenings)

Personal Curriculum Vitae

Marten Vijn, born 1967

This makes me happy… I like exploring, recognizing, meandering and discovering what is there, not necessarily what needs to be done. I like to be close and that I can still feel: I am me and you remain you. I love the truth, how truth resonates in the heart, and the heart returns words for refinement. I like to play with language, but not with spelling. I understand quite a lot about dyslexia, autism, intelligence, loneliness and being alone. I do understand a lot about fatherhood and co-parenting. I could help your co-parenting. If wished, my co-parent can also stepin. I can do a lot with persevering, taxing, overloading, limiting, letting go, expanding, being sensitive and powerful, charging and making space, integrating, also traveling to the stars and back. Listening and feeling what is needed or wants to happen, often even before there are words; call it intuitive or highly sensitive.

Regular education
  • Physiotherapy (1994)

  • Occupational Therapy (2000)

I have worked in a nursing home and in hospitals and later in a rehabilitation center.
