His dedication to the sport has earned him 6 US National records, 2 North American Continental records, and 2 consecutive years of bronze medals at the CMAS World Championships. With over a decade of experience free diving, Daniel has been able to share his incredible amount of knowledge in the sport to help others progress steadily and most importantly safely.
