I currently train GPs in the practice and completed a PGCE in Medical Education and Leadership in 2013. I was awarded Fellowship of the RCGP in 2018.

I am married to a now retired Gynaecologist and have 3 adult children, all still financially dependent for the next few years so I won't be hanging up my stethoscope any time soon.
