about Me

My name is Dr Mark Crouse, and I have previously worked in Cornwall as a GP for 20 years.


My broader experience included working as a Civilian Medical Doctor and Military Medical Examiner with the Royal Air Force and Royal Navy, and most recently specialising as a Disability Analyst.


I am one of a small number of doctors formally trained in lifestyle medicine.

My Story

While appreciating the rewarding, privileged position I held as a GP, I’ve always known that I could be doing more for my patients if I wasn’t constrained by short consultation times, the need to medicate or the lack of collaboration between patient and clinician. LifestyleDoc is my chance to help my patients by tackling underlying lifestyle problems at their roots, and move away from the quick-fixes becoming too common in today’s NHS.


A sound clinical knowledge is of course essential for an accurate diagnosis, but real change requires a broader knowledge of the specific circumstances, communication and trust. Treatment plans simply can’t be adequately formed through a two-minute discussion at the end of a consultation. They have to be put together like pieces of a puzzle: carefully and precisely, whilst always looking for the bigger picture. 


The evidence for lifestyle medicine being an effective form of treatment is, at this point, overwhelming, with endless examples of patients overcome issues such as obesity, high blood pressure and even diabetes coming directly from a change of lifestyle. Investing time in a patient, understanding their specific needs and background, is a service we all deserve to receive. 

Lifestyle medicine

In 2018, I made the decision to change my career direction. Studying Lifestyle Medicine as a discipline, I completed the Diploma of the International Board of Lifestyle Medicine (Dip IBLM), joining a small group of highly specialist doctors worldwide. As a member of the British Society of Lifestyle Medicine, I am leading the way in this innovative attitude towards health across the UK and beyond. 


This change in field has rejuvenated me as a person, and as a professional. Addressing the negative lifestyle habits in my own life has made me happier, healthier and driven to share my knowledge with you!
