About Us

Vision

At Spectrum Sisters Ltd we specialise in supporting girls and women with autism and ADHD through specialised diagnostic assessments, to ensure you get the support that you need.  Our aim is to provide a holistic, person-centred, neurodiversity-affirming approach that values strengths, talents, and lived experience.

We understand that women and girls often present differently and may have been misdiagnosed or overlooked due to male-focused assessment tools or a lack of understanding of masking and female neurodiversity. That’s why all our assessors are female, with lived experience, and expertly trained in supporting this population.

We are committed to empowering women and girls, ensuring their needs are understood, supported, and valued.  With practical, personalised guidance, we help individuals achieve independence, wellbeing, and safety in all areas of life.

We see Spectrum Sisters as not just an assessment and support service — but as a movement.

We see you. We recognise you. We’ve lived it. We understand.

Expertise

Our assessment team is highly unique. We are an MDT multi-disciplinary assessment team (as per NICE guidelines). Every one of us is a highly-trained professional from the fields of psychiatry, psychology, mental health nursing, social work, occupational therapy, educational psychology, speech and language therapy and neuropsychology.  What sets us apart is that in addition to this we all hold a professional interest and have had in-depth training in the female presentation of neurodiversity, and we are all females with lived experience in this area. In addition, every one of our assessments involves an in-depth review by our MDT team, with not just a diagnosis, but a detailed neurodevelopmental profile and recommends and a functional impact report.

This means, that when you get an assessment from us, you can ensure that it will be highly-specialised, high-quality, person-centred and with in-depth understanding and knowledge of the female Autism and ADHD phenotype. All our reports involve three clinicians and are psychologist led, a full neurodevelopmental profile and wellbeing assessment, detailed functional impact and recommendations for funding, signposting and a follow-up appointment to discuss outcomes. We strongly believe with the right understanding, support, and scaffolding, women and girls with neurodiversity can learn to fly! 

If you are a practitioner who aligns with our values and feels you may want to join our team we would love to hear from you as we are currently hiring. 

Benefits

Many people ask us why assessment is necessary?  Why label your child or yourself?  What are the benefits? 

Women and girls with autism are currently vastly underdiagnosed, misdiagnosed, and/or are diagnosed later in life than males.  Yet early identification and intervention has been linked to improved functioning and wellbeing of people with autism. Girls and women with autism are more likely to be victims of bullying, child abuse, poor health care, domestic violence, sexual assault, crime, depression, addiction problems, social isolation, PTSD, poor living conditions, poor employment, and affects them across the lifespan. A diagnosis can help to access well-designed support around understanding of oneself and prioritising safety, assertiveness, good mental health, and self-determination. It can also help to empower our girls to become the amazing people that they can be with the right understanding and support in place. All our assessments include detailed recommendations that can be used for funding and for reasonable adjustments for the workplace for adults, and for children in school.
