Gavin Jennings [CHEK Practitioner Level 4]

Chief Executive Officer

Gavin has a very varied career spanning over 30 years of owning his own businesses in various industries.

Before taking the reins of the global company as CEO in 2017, Gavin had spent 15 years running a string of his own very successful CHEK Clinics, employing CHEK Practitioners, Medical Doctors, Physiotherapist, Osteopaths, Chiropractors, Remedial Therapists, Psychotherapists, Functional Medicine Doctors and Traditional Medicine Practitioners.

This very expansive experience has allowed Gavin to see behind the curtain in many healthcare professions, and this experience inspired Gavin’s many creations within the CHEK Institute.

In 2014 Gavin founded the CHEK Academy, initially to help students in the UK study with the CHEK Institute’s advanced education programs whilst still working full time and to master the art of being a CHEK Practitioner, rather than passing exams.

For students who may not previously have had been successful in traditional academic studies, Gavin says “I left school at 16, without any formal qualifications that were appealing to employers, so after a succesful apprenticeship in the building industry, I started my own companies – first in the building industry then in retail and wholesale, and then finally when I turned 30 in the health care industry.”

Because of the issue that many health care professionals face, a lack of business skills, Gavin built and delivered extensive business training and mentorship for all students, based on his own experience and what he had proved had worked within real clinics.

In 2017, Gavin took CHEK Academy global with online learning, and has updated all online content for the Academy during 2020. The Academy student intake has doubled in size every year since 2018.

Since then, Gavin and the CHEK Institute Team have successfully launched the CHEKIVA free platform, built the first CHEK Media Film Studios in the UK, and opened the CHEK approved E-commerce store in 2020.

Gavin is passionate about the vision and values of the CHEK Institute and all of it’s practitioners and is a shining example of a successful health entrepreneur.
