I am a Consultant Cardiologist based in Colchester and Ipswich. I see patients from across Essex and Suffolk. My main private practice is at The Oaks, Colchester and the Nash Basildon Private Unit at The Essex Cardiothoracic Centre, Basildon.
My practice covers the whole spectrum of adult cardiology including chest pain, breathlessness, heart failure, high blood pressure, murmurs, blackouts and palpitations. My comprehensive training in Glasgow and London resulted in accreditation in both Cardiology and General Medicine. I can therefore offer a more holistic review when considering problems relating to your heart.
I have been a Consultant Cardiologist at Colchester Hospital since 2006 and at the Essex Cardiothoracic Centre since it opened in 2007.
In April 2010, I became the Clinical Lead for Cardiology at Colchester Hospital. I have led the introduction of many advances in cardiology services, including valve clinics, heart failure services, MRI compatible pacemakers, implantable loop recorders, stress echo, transoesophageal echo, 3D echo and CT coronary angiography. I am accredited in echocardiography with the British Society of Echocardiography and in CT Angiography with the British Society of Cardiovascular Imaging.
In 2016, I forged new links between Colchester and Ipswich Hospital's cardiac services, providing specialist cardiac imaging for Ipswich Hospital. In October 2017, I became the Divisional Director for Medicine and Emergency Care at Colchester Hospital. When Colchester merged with Ipswich Hospital in July 2018, I was appointed as Divisional Director across both sites.
I am passionate about improving patient safety and constantly look to improve both my practice and the standards of care where I work. This is reflected in my patient feedback. I am an active member of the education committee of the British Society of Echocardiography, contributing to guideline development and training programmes.
