Administrative Lead

Mike will be your first port of call when you get in touch with us. He has over 15 years’ administrative experience and has worked as an administrator and receptionist in paediatric departments, as well as in adult and children's mental health, and in roles with vulnerable adults.

He has extensive experience speaking with patients with ASD and ADHD, learning disabilities, and mental health conditions, as well as their families. He holds an enhanced DBS with barred list checks for both adults and children and is fully versed in data protection rules.

The partnership originally began under the name Sphere Autism Service, offering assessments for Autism Spectrum Disorders in pre-teen children. Since forming, we have expanded our services, now offering Autism assessments for children and young people aged 2 to 19, as well as ADHD assessments for children and young people aged 6 and over, standalone General Developmental Assessments, and a range of post-diagnostic support. In September 2024, we changed our name to The Sphere Centre to reflect this wider range of support and services being offered.
