Bio's
Patrycja
Having a rich background in the clinical field, including a master’s degree in Psychology, experience helping people with lifelong conditions such as Parkinson Disease, Dementia, Brain Injury, Autistic Spectrum Disorder, Personality Disorders, and Addictions.She followed two postgraduate trainings in psychology; one in Psychological Therapies and Neuroscience and one in Mindfulness. Other relevant experience comes from the counselling field, supporting youths, ex-offenders, people who experience homelessness, substance misuse, foster care and domestic violence but also with couples and families. She has worked with people who struggle with depression, anxiety, eating disorders and complex trauma. Her work has helped Patrycja deepen her understanding of the complexity of the needs of various kinds of patients and to see what it really takes to develop higher levels of strength and determination to be ready to move on and make a change in our lives.Patrycja’s experience coaching and mentoring manager’s level staff allowed her to develop a broad range of tools for supporting peak performance, creativity, stress resilience and emotional intelligence in human interactions.Her approach is guided by many models and trainings; including Cognitive Behavioural Therapy, Mindfulness, Mind-body approaches, Somatic therapy, Polyvagal theory, Brain spotting, Deep brain reorienting, Neurofeedback, Internal Family System and Hakomi therapy. These tools help to identify negative core beliefs, negative patterns of behaviour and mind traps and allow people to develop emotional regulation skills and to discover potential, strength and wisdom in themselves.Having been trained at King’s College London and Queen Mary University, Patrycja has a high level of academic training and is equally at home in an academic as in a therapeutic setting.
Patrycja has experience working with patients with psychological crisis and trauma.When MAPS first came to Europe in 2018 to train representative local therapists for the European part of the trial for MDMA assisted psychotherapy for PTSD, Patrycja was fortunate to be invited to follow the training which was a great opportunity for her, not only to learn from two highly respected and experienced trainers in the field of therapy assisted by psychedelic states (Michael and Annie Mithoefer) but also sparring with professionals of different fields related to the study and learning from extreme clinical case examples.
Coen
Also has a scientific background as he has studied physics as well as having studied design, which added a more right-brained development.
His main strength comes from his experience working with psychedelic states. First at an Ayahuasca retreat centre in the Netherlands where he received training and the chance to really develop his skills at sitting with people in powerful transformational experiences. This was an amazing environment to learn and develop and he guided many groups, allowing him to learn from hundreds of different experiences while being part of diverse teams of sitters and ceremony leaders. These basic space holding skills form the solid basis and are still the core of his approach to healing.
When Patrycja and he met and started working together, she was (apart from much more) a great partner in solidifying and professionalising his skills. Which they did together as they trained in Hakomi and IFS and traveled the world together for workshops, trainings and conferences, while working on their own personal growth and with their clients. Over the years his training has covered areas that include IFS, Hakomi, Couples work, Neurofeedback, Holotropic Breathwork and the MAPS approach.
In the mean time he was invited to join the UK based PHP Network as one of the founding members. This is a self organised (and evolving) group of mental health professionals who have decided to prepare for the (obvious) coming medicalisation of psychedelics. With PHP he trained, teaches and guides group retreats in the Netherlands while learning from collaborating with psychiatrists, doctors, nurses, councellors and the retreat participants.
Over the years Coen has developed into a highly experienced psychedelic guide and therapist with a deep capacity to sit with you through your experience, whatever it may bring. Meeting you where you are and guiding you with the ability to resist the seductive impulse to take you away from the difficult processes that you may need to face.
We both
share a passion for self development and personal growth; not just with the help of psychedelics, some of our most profound experiences have come from facing and staying with our own pain with the loving support of the other. We are both in training to become Hakomi Somatic Mindfulness based therapists, a method that is aimed at working with our subconscious material making it ideal for working with psychedelic experiences.
We both have a strong international mindset, with Patrycja having lived and worked in Poland, the US, Ireland, the UK and Holland. And Coen having lived in Curacao, Malaysia and Holland. Almost all of our trainings and the workshops we have done have been international ones and the vast majority of our clients are international.
We also have three cats who we love much more than we could ever imagine.

I am Coen de Koning,
A therapist specialised in supporting psychedelic experiences
with over a decade of experience in this field, most of it full time.
Born: 24th of February 1980
Together with my wife, Patrycja Radecka - de Koning, I run a private practice specialised in supporting legal psychedelic experiences, mainly for international clients. We also offer (sober) online therapeutic support.
Our practice is called TSS; Therapeutic Sitting Service.
Apart from my work with TSS I am a part of
the UK based PHP - Psychedelic Health Professionals Network
and I support IFS trainings as a Program Assistant.
Occasionally I get to support other trainings and retreats.
As a team player, I have roughly 10 years of experience
guiding groups in diverse teams including psychiatrists, psychologists, doctors and nurses.
I have facilitated hundreds of psychedelic experiences, privately and with groups as part of different teams.
I am a membership of the European Association of Body Psychotherapy.
Professional experience:
2017 - Present; Founding partner and therapist at TSS
- we offer support for psychedelic experiences based on our training and experience as therapists as well as our MAPS training.
We work 2:1 during our 3-day or 6-day in-person retreats and
we work 1:1 in our online preparation and integration sessions and
with our non-psychedelic clients. We also work with couples.
In TSS we only support Psilocybin truffles experiences as we work above ground and Patrycja is licensed with the NIP; Dutch institute for Psychologists. As TSS we have offered group retreats in collaboration with others in the past but only work privately and not with groups at this moment.
2020 - present; Facilitator and founding member of PHP network.
PHP or the Psychedelic Health Professionals Network is a UK based (not-for-profit) organisation by a group of mental health professionals who predict the medicalisation of Psychedelics and who try to prepare for it by educating themselves and their colleagues as well as the general population. This includes lecturing, training and also offering legal psilocybin group retreats in the Netherlands. I have been supporting the organisation and organised and was a facilitator for many of their group retreats. These are 6-day and 2 experience retreats with between 12-16 participants and run by a team of 3-4 facilitators and often with 1 or 2 assistants.
2025; Trainer/facilitator at a weeklong MDMA experiential
facilitator training retreat
Based on a pilot in 2024, this was a closed training retreat aimed at
offering a purely experiential facilitator training to complement the myriad of more theoretical psychedelic trainings that are offered around the
world. The training group was divided into pods where each participant would have one MDMA experience and sit twice for their other pod members. I was a trainer/facilitator supervising one such pod; as such I did not have an MDMA experience but modeled for and supervised the guiding, the preparation and integration processes. Apart from the experiences the retreat included daily cross-pollination sessions where experiences were shared between the pods.

2013 - 2017; Facilitator at the Sacred Voyage.
In these years was a facilitator for well over 20 different retreats as a part of the team of facilitators of the SV. These retreats were mostly 2 day or 3 day weekend retreats with either one or two Ayahuasca ceremonies and with groups varying between roughly 10-30 participants and between 3-8 members of staff. I have also been on the team guiding their 5-day retreat and both followed, and was a staff member supporting, their year training.
The training and retreats included sharing circles, movement meditation and connected breathwork, occasionally sweat lodge ceremonies.
