Dr Mark Bish (Senior Partner)

Dr Bish, our senior partner, trained at St George’s hospital in London. After qualifying he worked for 5 years in hospital medicine around SW London and Surrey. He gained experience in multiple medical specialties including gastroenterology, neurology and endocrinology before training to be a GP in 2008. He started as a partner at a Wimbledon GP practice, before moving to the Hart in 2013.

Dr Bish is married to Dr Worth, with 2 children who are growing up fast. He loves all sport and was a keen gymnast in his childhood which remains useful for the occasional party-trick.

5 years later and with the arrival of 2 children she was lucky enough to complete her GP training with the Hart Surgery. She was delighted to be offered a job to stay on as a salaried doctor.

Over the course of her training, she has worked in a number of hospital specialties including obstetrics and gynaecology, paediatrics, acute medicine and elderly care. Her interests include women’s health, general medicine and palliative care. She also looks after patients at Chilterns Court Care Home.

Her “free time” is now occupied by her two very active young boys, but she dreams of one day enjoying a busier social life, fine food and Italian holidays!
