Freediver Public speaker and Breath Trainer


I grew up in London and was a water baby from the start.  I learned to scuba dive aged 12 and enjoyed it for many years but always found it to be a bit noisy and cumbersome. While travelling in Thailand in 2013, I discovering freediving and it was love at first dive!  I found a deep level of  peace and tranquility that I wasn’t able to access whilst scuba diving. Shortly after starting to freedive, I had to take a year away from depth for personal reasons but returned and in 2015, I was selected to attend the biennial Individual Depth World Championships in Cyprus on the British Team.  I placed overall 10th out of 30 women. In 2017 I attended the same event, this time in Roatan, Honduras where I placed overall 5th out of 31 women. In August 2019, I competed in the Caribbean Cup in Roatan Honduras, gaining my first 2 national records in CWBF followed by the CMAS World Championships where I took all 4 depth national records.  Then onto Villefrance-sur-Mer, France for the AIDA World Championships where I secured 3 white cards for successful dives and came 4th overall out of 46 women. My passion is for the depth disciplines, but I use the pool for training when I am London based and unable to access deep water. I am an SSI Level 2 Freediving Instructor and have a healthy passion for Yoga.  I relish both the physical and mental side of free diving and look forward to consistently increasing my depths over the coming years.



BESTDIVE Ambassadors —— David Mulheron

Australia National Record


In 2016 decided to complete a Freediving course to learn better technique to dive deeper and safer. Completed level 1 through to instructor at Freedive gili in Indonesia. Last year I decided to try some pool competitions. I also spent 4 months depth training so in 2019 I would be ready to try some depth competitions. I completed in 3 depth competitions including the world championships. I set a new National record in CWTB 86 meters and won best male freediving athlete for 2019 from the Australian Freediving Association in my first year competing in depth. My competition performances were much less then my current training PBs but I’m sure these will improve as I gain more experience.
