Tutors & Assessors


All of our tutors have worked within health, fitness, sports and wellbeing industries all their working lives, bringing together many years of varied experience. We are proud to still all actively have our own health & fitness businesses, so we still live and breathe the information that we share with you.

I now have 19 years of experience in the health, fitness and wellbeing industries, which is scary!  In that time I've worked as an exercise physiologist for BUPA, a wellbeing consultant to Sussex Police and many years of personal training and class instruction both privately and at top health club chains such as David Lloyd and Nuffield Health, as well as Central YMCA. I currently have my own personal training studio, which is the new home of Pro Fitness Education.  I haven't stopped learning in all those 17 years and I'm currently studying my Level 4 tutor and assessor.

Movement Analysis & Training

I have been working in the industry for 17 years, and continue to follow this journey.  I was lucky enough to work as a personal trainer on the cruise ships and see the world. I still actively work as a class instructor, personal trainer, and manage a local gym. The opportunity to share that passion through Pro Fitness Education is something I really enjoy. If I am not doing any of these above, you will find me outside mountain biking, climbing, kayaking, or competing in obstacle running events such as tough mudder, rough runner events.  I'm also surprisingly good at basketball!

I have worked in the fitness industry for over 17 years and have loved every day of it.  No day is ever the same and the joy you get from helping change peoples lives is awesome.  During my time in the industry I have worked in many areas, these include – gym/group exercise instructor, management, personal trainer and now as a tutor/assessor.  In 8 years as a tutor/assessor I have been privileged to teach in the UAE, India and many places in the UK.  I have also written several courses.  I believe anyone can achieve anything in their life including their fitness goals.  You just need that belief that you’ll succeed and a little hard work.
