Michaela Nuttall is C3’s associate in nursing. She is a cardiovascular nurse specialist with a unique and varied experience across the NHS and beyond. She developed her passion for prevention 25 years ago and has worked within it ever since.

Having left the NHS after 27 years, Michaela is the clinical director at Smart Health Solutions, founder of Learn With Nurses and is overjoyed to have joined C3 in 2016.

In 2019 she was Deputy National Lead for CVD Prevention at Public Health England and now remains as a clinical advisor.

Often seen as the voice of reason and bringing balance and a pragmatic approach to prevention and health, she is the Chair of the Health Care Committee of Heart UK and an invited member of both the Nurses and The Guidelines and Information working party of the British Hypertension Society, elected member of the Association of Cardiovascular Nurses and Allied Health Professional Education working party, on a variety of editorial boards and the Global Cardiovascular Nursing Leadership Forum.

I am an Associate in nursing at C3. I am also an overseas Dentist. I work clinically as a Dental Therapist and am passionate about preventative dental care that includes educating patients on the importance of maintaining good oral hygiene and its implications on general health and well-being. In the past I have also worked for the NHS to reduce oral health inequalities across the borough of Tower Hamlets, having treated and educated pupils in more than 70 primary schools in the borough.

From my own personal experience after my overall health took a toll post-pregnancy, I realized the crucial role public health can truly play in an individuals’ health. This made me more passionate about the wider determinants of health in stark contrast to just clinical treatment alone. I completed my Masters in Public Health from University College London.

I am also an Associate member of UK Faculty of Public Health contributing to a few of its SIGs – special interest groups.

Molly’s role:

I believe that healthy food plays an important role in lowering risk factors for chronic disease. Love experimenting cooking using healthier ingredients but also ensuring not to compromise the taste and the sheer joy good food brings.

Andy Jones is an associate at C3.

Andy has over 30 years’ experience as an academic. He graduated with a degree and PhD in environmental sciences and undertook research in that field for many years, becoming increasingly interested in the role of the environment as a determinant of population health. In 2012 Andy transitioned to working full-time in the field of public health by joining Norwich Medical School at the University of East Anglia as a Professor of Public Health where he led the Department of Public Health and Health Services Research. More recently he has worked in the public health team at Norfolk County Council, acting as an expert advisor in the use of research and evidence in public health delivery.

Andy has strong interests in the evaluation of health-related interventions and has partnered with a wide variety of organisations to support evaluation work, including local and central government, the third sector, health services, and academia. He uses more formal study designs such as randomised controlled trials, but he has a particular passion for taking a pragmatic approach to evaluation, which involves the application of mixed methods to fit evaluation around programme delivery to ensure high-quality evidence is produced on how programmes work in real-world settings.

Andy’s role:

At C3, Andy’s work involves the identification and delivery of research and evaluation opportunities to support the activities of the organisation.

How Andy practices what he preaches:

Andy is a keen runner and cyclist and uses his bike rather than driving when possible. He used to run competitively and came 155th out of 35,000 finishers in the 2008 London marathon. Deciding he was unlikely to better that, he now focusses on recreational running from his home in the Norfolk countryside. He finds the scenery moves past him more slowly than it used to, but the benefits to his mental and physical health from running are just as strong!
