Meet the Team


Our Founder

Katie Barnes is an advanced paediatric nurse practitioner (APNP) originally from the USA, with over 25 years of experience, nationally and internationally, across the NHS, academia and health care policy circles. She has a track record of innovation, children’s service redesign, advanced practice education and paediatric clinical practice excellence.

Her passion for the improvement of health care for children and young people through advanced practice education, advocacy and new model’s of health care delivery led her to create KHM.  

Katie edited the first paediatric advanced practice text in the UK and developed the first (exclusively) paediatric MSc advanced practice programme.  Her service re-design projects are often at the forefront of innovation and excellence – in 2013 her team won Clinical Team of the Year (Children) at the General Practice Awards and they were also a finalist for two additional Health Services Journal (HSJ) awards.

Her work in developing and implementing paediatric advanced practice in the UK earned her a place as a finalist in the 2012 Nurse of the Year Awards and then in 2014 she was honoured by the Columbia University School of Nursing Alumni Association with their Award for a Distinguished Career in Nursing Education, Practice and Health Care Policy.

She is currently building a paediatric advanced practice workforce in the Northwest and working with Health Education England to develop the curriculum that will underpins these new roles .  Her clinical practise as an APNP is based in the Emergency Department at Alder Hey Children’s Hospital, NHS Foundation Trust.

Katie does all this while holding down the fort in her Liverpool home where she lives with husband, three children and liverly Patterdale terrier. 

The Team


Cheryl Clarke is the lead of our Acute Paediatric route for Advanced Paediatric Practitioners.  She started paediatric nursing back in 1996 as a member of the first Project 2000 cohort in the North East of England.  From Teesside to Liverpool, she has worked in acute, high dependency and intensive care environments and always kept clinical education at the forefront.  In 2005 she joined LJMU to deliver the Paediatric High Dependency module and it was there she met Katie.  She earned her MSc in Nursing and a PG Cert in Higher Education and in 2009 began teaching on the LJMU APNP MSc.  She was part of that programme for four years before returning to full time clinical work as an APNP in Alder Hey’s high dependency unit.

She couldn’t have been happier to join the KHM team in 2017 to lead the MSc acute paediatric route.  She loves sharing her knowledge and skills in the classroom and clinical setting and hopes to pass on her passion for the role.  Between clincal shifts and teaching sessions, Cheryl loves to take her children to visit the lovely Welsh sheep and cows that live next door.


Sue O’Neill is a Neonatal Nurse Consultant and lead of our Advanced Neonatal Nurse Practitioner (ANNP) route. She started her nursing career in Paediatrics but quickly found her passion for neonatal nursing and has been working at Liverpool Women’s Hospital since 1995. She qualified as an ANNP from Southhampton University in 2001 and has loved working as an ANNP on the Neonatal Intensive Care Unit since then. Over the last 17 years she has seen many changes in advanced practice and she counts herself lucky to be surrounded by a team of great, likeminded people who value the contribution ANNPs make to this extremely vulnerable population and their families. Sue was appointed to the role of neonatal nurse consultant in 2016 and she now leads a team of 20 ANNPs.

She has been involved in ANNP training throughout her career and was thrilled to be part of the KHM team delivering the ANNP course, which is a first of its kind. She is immensely proud of what the team has achieved so far and will continue to achieve in the years ahead building a very bright future in advanced practice in neonatal and paediatric care.
