Meet the team

Every member of our team is here because they care deeply about heart health — and about making sure you feel comfortable, informed, and looked after.

More than qualifications

Between us, our team brings over 150 years of cardiology experience. We’ve worked in some of the UK’s leading NHS cardiac centres, trained the next generation of physiologists, and cared for thousands of patients along the way.

But what makes this team different isn’t just what’s on our CVs. It’s how we work. Everyone here was chosen because they share the same belief: that a heart scan should never feel rushed, impersonal, or intimidating. We take our time with every patient, we explain things clearly, and we treat you the way we’d want our own family to be treated.

We have both male and female physiologists on the team — just let us know your preference when you book. Every scan is peer-reviewed by a second Advanced Cardiac Physiologist as standard, and an optional Consultant Cardiologist review is available on your echo for additional reassurance — so you can be confident your results are in expert hands.
