Oliver Ackermann

Oliver is a psychotherapeutic counsellor passionate about helping people struggling with addiction, behavioural compulsions, trauma, OCD, anxiety, and depression.

He takes a person-centred approach to therapy, which means he believes that each person has the capacity to heal themselves. He employs mindfulness-based interventions, cognitive behavioural therapy, and motivational interviewing to help his clients develop the skills necessary to overcome their challenges.

Oliver is also trained and certified in Attachment-focused EMDR, which emphasises a reparative therapeutic relationship using a combination of Resource Tapping to strengthen clients, EMDR to process traumas and talk therapy to help integrate the information from EMDR sessions and to provide healing derived from therapist-client interactions. Attachment-focused EMDR can be used for clients with severe early attachment trauma.

Oliver is also passionate about integrating holistic treatments with traditional psychological interventions. He believes that the mind and body are interconnected and that a holistic approach to therapy can be more effective than traditional methods. Oliver is originally from Switzerland, but he has lived in Singapore for the past 22 years. He is fluent in English and German, and he has basic communication skills in French.

Oliver Ackermann

“I want to express my deepest gratitude to my EMDR therapist at Stillness of the Heart. Your compassionate guidance helped me face and heal from the shadows of my childhood trauma. Through your skilful support, I found the strength to reprocess painful memories and reclaim my peace. You created a safe space where healing could truly begin, and your belief in my resilience gave me hope when I felt lost. Because of you, I am no longer defined by my past but empowered to embrace a brighter future. Thank you for walking this transformative journey with me.” - PK

Whether offering guidance or simply listening, Oliver has been an invaluable support in my journey. I highly recommend him to anyone looking for a therapist who truly cares.” - Bryan

  • Oliver is a fine therapist and one skilled in EMDR. He provides a safe space to navigate one’s inner world, and I would highly recommend him and Stillness for anyone keen to dig deeper into their being. He is equipped with the latest technology and a wonderful sense of humour, both of which help ease the process. - Anjali
