Meet The Team

Our team

Brian Graddon - President



Brian graduated from the University of Washington with a degree in Business/Finance prior to moving south to San Diego. After a brief stint in finance, Brian shifted gears to become a Firefighter Paramedic, going on to work as a SWAT Medic, Engineer, and Captain over a 15 year span. Seeing the amazing potential of defibrillators first hand, but often arriving too late in the critical minutes following sudden cardiac arrest, Brian co-founded AED Leader in 2008 with a goal to place more of these life-saving devices into the hands of the public. In his off-time Brian stays busy raising 3 rambunctious daughters with his wife Elizabeth, and keeping active with surfing, rock climbing, and mountain biking.

Elizabeth Graddon



Elizabeth was a collegiate gymnast at Sacramento State University, California where she earned a Bachelor’s degree in Nutrition. Continuing her interest in wellness and healthcare, Elizabeth went on to earn her license as a Registered Nurse. Her passion for helping others led to positions in several areas of healthcare in both hospital and pre-hospital settings. Through this experience she became acutely aware of the lack of basic life-saving equipment in workplaces and in homes. This led to the life- changing decision to found AED Leader along with her husband, together bringing their frontline experience and perspective to the task. When she is not working on the business she loves running trails, surfing, and spending precious time with her three daughters.

Kassandra Adger


Client Relations Specialist

Kassandra has a passion for learning and serving others. These passions pushed her to pursue and complete her Master’s in Kinesiology with an emphasis in Exercise Science at Point Loma Nazarene University where she learned the risk factors of cardiovascular disease and what that could lead to. Learning and understanding the importance of rehabilitation for patients after surviving a cardiac event also meant seeing how many patients unfortunately don’t make it.

This knowledge as well as 8 years of customer service experience have uniquely prepared Kassandra to assist AED Leader customers. In her free time, Kassandra enjoys yoga, going to the beach, and hosting her friends for dinner.
