Our Team
Dr Evan Wilson
Psychiatrist
Bachelor of Medicine and Bachelor of Surgery
Master of Health Service Management (Distinction)
Fellow of the Royal Australian & New Zealand College of Psychiatrists
Evan is a specialist in in child, adolescent, and youth psychiatry, and brings a wealth of clinical experience in diagnosing and supporting individuals with ADHD and autism, as well as managing conditions such as anxiety, OCD, PTSD, and mood disorders.
Evan is a passionate advocate for neurodivergent individuals and their families, committed to championing the needs and strengths of neurodivergent children to create greater understanding, acceptance and support for them. He aims to help young people navigate external stressors, overcome barriers, unlock their full potential, and reduce the impact of mental health challenges on their lives.
Evan has also worked extensively within the public health sector and saw the detrimental effects that prolonged wait times have on a young person's recovery and the heavy toll it takes on their family’s wellbeing. This led him to start Mind Horizons, where his goal is to deliver outstanding and prompt psychiatric care. Evan was also recently involved in a series of videos for the charity Working for Families, where he shared accessible, practical guidance for families navigating OCD. This reflects the same values that shape his neurodiversity advocacy: listening, understanding, and clear communication, which helps families feel informed and less alone.
Evan earned his medical degree in Dunedin before practising in the public health sector across both Invercargill and Christchurch. In addition to his clinical practice, Evan is a strong advocate for healthcare system enhancement and medical leadership. He has held multiple advisory positions within the Royal Australian and New Zealand College of Psychiatrists (RANZCP), including roles on the Members' Advisory Council, the Trainees' Advisory Council, the Bi-National Committee for Trainees, and the Climate and Sustainability Steering Group.
Outside the clinic, Evan is a dedicated swimmer. A former New Zealand representative in the 10km open water freestyle, he maintains his connection to the sport with morning training sessions before work. He also loves exploring the outdoors on camping adventures with his wife and their two young sons. Back in the office, his love for collecting kinetic art and sensory toys adds a fun, interactive atmosphere to his clinical space.

Born and raised in Christchurch, Dr Cederman completed his medical degree at the University of Otago before returning home to practise in 2017. He is a specialist child, adolescent, youth, and family psychiatrist with experience supporting young people and families across a wide range of conditions, including ADHD, anxiety, depression, OCD, PTSD, and autism.
Dr Cederman is known for combining clinical expertise with a warm, positive approach. He believes that understanding a person's strengths is just as important as recognising the challenges they face, and he works collaboratively with young people and their families to help them thrive.
In addition to his core psychiatric training, Dr Cederman has extensive experience in a range of evidence-based therapeutic approaches, including Cognitive Behavioural Therapy (CBT), Interpersonal Therapy (IPT), and Family Therapy. This allows him to offer comprehensive, personalised care that goes beyond medication alone, supporting lasting health and resilience.

He believes that accessing support at the right time can make a significant difference in helping children, young people, and families build confidence, emotional strength, and lifelong wellbeing.

Annah Hennessy
Social Work Therapist
Master of Social Work (Applied)
Postgraduate Certificate in Health Science in Mental Health and Addictions
Postgraduate Certificate in Health Science in Cognitive Behaviour Therapy
Kia ora! My name is Annah. I am a Registered Social Worker with nearly eight years of experience within the Child, Adolescent and Family Mental Health Service, helping young people work through anxiety, depression and other mental health challenges; including when things feel really heavy or hard to manage on your own.
I use Cognitive Behaviour Therapy (CBT) as the foundation of my work, which is a practical, evidence-based approach that focuses on understanding the links between your thoughts, feelings and behaviours and with that, building tools that actually make a difference in day-to-day life. I have also completed a comprehensive training in Dialectical Behaviour Therapy (DBT), so I bring in skills around managing intense emotions and distress, when that is useful for you. I take an integrative approach, incorporating strategies from other modalities as needed.
My experience contributing to an ADHD-specific multidisciplinary team, along with my own lived experience of neurodivergence, has contributed to my passion for working with young people navigating their own journey. Whether you have just received a diagnosis or have known for years but are still figuring out what that means for you, I'm here to help you make sense of it. Not to "fix" your busy brain, but to understand how it works and build the life you want to have in a way that fits. For teenagers, this can look like figuring out what you actually need and building real, practical skills to manage school, friendships, emotions and everyday life. For parents, it's about feeling confident and equipped, with less second-guessing and more clarity on how to support your young person and be kind to yourself in the process.
I know starting therapy can feel like a big and sometimes scary step, especially if you're not sure what to expect or whether you'll be "taken seriously". For me, the relationship we build together is at the heart of good therapy. I take the time to actually get to know you; what matters to you, what you're into and what makes you you, because you are the expert on your own life. Therapy works better when it doesn't feel overly clinical or distant, so I bring humour and use metaphors to help make sense of things; because sometimes a good analogy lands where a textbook explanation doesn't.
When I'm not at work, you'll probably find me attempting to drag my dog around the block on our daily walk (she prefers to snooze in the sun), baking sweet treats, singing to music I don't have the vocal range for, or working hard to keep my balance in Pilates.
If you are a young person wanting to make sense of things and build skills that stick, with someone who will celebrate the wins with you, or a parent who thinks that I could be a good fit for your young person, I would love for you to get in touch.
