Swantje is a Sydney-based ADHD life coach. Apart from her specific ADHD coach training (ADDCA), she has a strong academic background (BA HONS Philosophy) and is passionate about her ongoing professional development and ADHD advocacy.

Swantje was born and raised in Germany and after living in several European countries settled in Australia 20 years ago. She has raised 3 ASD/ ADHD children and received her own diagnosis 5 years ago. After a short period of grief, she experienced her diagnosis as a huge relief: it gave her the opportunity to make sense of her gifts as well as her organisational struggles.

In her past careers, Swantje has worked as an academic research assistant as well as a bespoke tailor in the entertainment industry – she is proud to have been able to access the theoretical as well as the practical side of her own brain. Her coaching style instills this confidence in her clients.

In her holistic coaching approach, Swantje has successfully worked with these client groups:  Adult late diagnosis, Adults parenting ADHD Children, Young Adults (uni students and professionals), Year 11 & 12 High School Students, clients with ADHD/ ASD and ADHD/ SUD.

I am a certified ADHD coach with my own lived experience of ADHD. Like many women, I was diagnosed with ADHD later in life. Shortly after, my teenage daughter was also diagnosed. Not wanting my daughter to have the struggles I had negotiating life with ADHD, I went in search of support. I discovered that what was available was limited and with long wait lists. Sadly, I encountered much misunderstanding of ADHD, at times from the professionals I was reaching out to. It became evident that the best way to assist my daughter was for me to learn as much as I could about ADHD, leading me to the decision to become an ADHD coach.

Before moving into ADHD coaching, I worked in the social welfare sector, specialising in case management and client support for individuals and families facing complex challenges such as homelessness, family violence, and child welfare concerns. I hold a Graduate Diploma in Social Housing Policy and Management from Swinburne University.

I understand how severely ADHD can impact every aspect of a person’s life but I also know that, with the right knowledge and support, people with ADHD can truly thrive and be free of the shame that often comes from living with ADHD.
