About ACT Complete Therapy

Mike van Diemen

I’m passionate about supporting people to create meaningful, lasting change in their lives in a way that feels safe, respectful, and genuinely tailored to them.


With a background in counselling, strategic psychotherapy, clinical hypnotherapy, mindset coaching, and complementary therapeutic modalities, I don’t believe in a one-size-fits-all approach. Every person is different, and effective therapy should reflect that. My work focuses on understanding you as an individual, then drawing on the most appropriate tools and techniques to support your goals, challenges, and strengths.


I work collaboratively with clients to create a supportive and practical pathway forward. This may involve addressing long-standing patterns, navigating life transitions, improving emotional wellbeing, or building clarity and confidence for the future. Sessions are guided by your needs, at your pace, and with respect for your lived experience.


You can explore the different services I offer to see what may be the best fit for you.
