David Keogh, our weight loss surgery co-ordinator, originally delved into the field of engineering. However, having discovered that this path wasn’t for him, he enrolled himself into a Bachelor of Science degree. Several years later David graduated with a degree in Sports Science and Health. Since then, David has attended the Royal College of Surgeons in London and completed courses in Bariatric Patient Management. He has also, completed courses under the International Olympic Council in Nutrition and Dietetics for Health and Fitness.
Whilst doing his degree David also gained several coaching qualifications including Olympic weight lifting, rugby, tenpin bowling and football.
Unhappy with his weight, David began following a diet and exercise program which he developed himself. Within one year David lost almost five stone in weight. During this time he developed an enormous interest in the topic of weight loss and weight management and decided to enter into the field of weight loss surgery in order to help others achieve what he had achieved himself.
In his spare time, David plays tenpin bowling and has represented Ireland on a number of occasions. He is also a keen marathon runner and takes great pride in helping others to achieve their desired goals.
