He then served as a Medical Officer in the Royal Air Force, starting as a General Practitioner and later training as a surgeon.

Following this, he worked as an Emergency Department Consultant at Bedford Hospital.

He also holds a Diploma in Medical Care in Conflicts and Catastrophes, as well as a Master’s in Aesthetic Medicine. These experiences have given him a comprehensive view of medical care both in the UK and internationally. ​ Dr. Khan is dedicated to understanding patient expectations and is a staunch advocate for a traditional model of patient care, where healthcare providers know their patients and act as partners on their healthcare journey. ​ Beyond his professional life, Dr. Khan believes in living life as a journey rather than a destination. He enjoys travel, reading, scuba diving, sailing, trekking, and meeting new people.
