About Dr Bozena ZoricPrivate ADHD clinic for children and teenagers
A children's ADHD clinic in Surrey, led by consultant paediatricians
Private ADHD assessments for children and young people aged 5 to 18, face to face in West Byfleet. Careful, unhurried, and with clear next steps for home and school.
- Ages 5 to 18
- No GP referral needed
- QbCheck included
- Face to face in West Byfleet
Worried about your child's concentration or behaviour?
Perhaps they struggle to focus, cannot sit still, act before they think, or find school much harder than it should be. Perhaps a teacher has raised it. Or perhaps school says all is well, but home feels exhausting and you sense something is not quite right.
These can be signs of attention deficit hyperactivity disorder (ADHD). A careful assessment with a specialist doctor can tell you whether it is ADHD, or something else, and what will help.
You know your child best. What you have noticed matters, and it is the starting point of every assessment we do.
Families usually come to us when a child:
- struggles to focus, follow instructions or finish tasks
- is restless, fidgety or constantly on the go
- interrupts, blurts out or acts without thinking
- loses things, forgets things and finds organising hard
- is falling behind, getting into trouble or losing confidence at school
- is anxious or low because everyday things feel hard
Why families choose BZ Clinic for a private ADHD assessment
Our doctors are consultant paediatricians, not psychiatrists. That means they are trained in children's general health as well as ADHD, and look at everything that might be affecting your child.
Consultant paediatricians
Doctors trained in children's general health as well as ADHD, so we look at the whole child: sleep, growth, hearing and anything else that might be going on.
Face to face, in West Byfleet
Every appointment is in person, in a calm consulting room above West Byfleet GP Health Centre.
QbCheck included
A computer-based test of attention, activity and impulsivity, included in every new assessment and usually done at home first.
NICE guidance, audited
Assessments follow NICE guidance for ADHD and are regularly audited, so your GP and your child's school can act on them.
How an ADHD assessment for your child works
From your first call to your child's plan, Camille and the team keep things clear and calm. Usually the doctor can give you a diagnosis, or a clear answer, on the day of the appointment.

Meet our consultant paediatricians
Both doctors are senior NHS paediatricians who have led ADHD and neurodevelopmental services in Surrey and beyond.
Dr Lisa Wall
Consultant Neurodevelopmental Paediatrician
Clinical Lead for Surrey Developmental Paediatrics since 2017, with over 20 years in neurodevelopmental paediatrics. Seeing new patients at BZ Clinic from November 2026.
About Dr Lisa WallBoth our doctors are NHS consultant paediatricians, regulated by the General Medical Council (GMC). They work for an NHS provider that is registered with the Care Quality Commission (CQC), and both their NHS and private practice are appraised and audited every year through that NHS employer's appraisal system. For this reason BZ Clinic is not currently required to register with the CQC.
This may change following the government's recent review of ADHD services, and we are monitoring it closely. All our assessments follow NICE guidance and every appointment is face to face.
