Company History – Founded in 1996 by Ray Jarris, Jr. MD, MA, FAAFP

Dr. Ray Jarris was a family and emergency medicine physician with a passion and vision for improving health and saving lives. With an entrepreneurial spirit, Ray founded companies that provided medical support to remote worksites. As a pioneer in maritime medicine, he saw how medical technology could be successfully used by those with limited medical training outside a medical environment and recognized the opportunity to bring these life-saving solutions to a greater audience. Ray realized early on the profound benefits of pre-hospital early defibrillation and the impact it would have on survival from Sudden Cardiac Arrest.

To honor Ray’s deep roots in the Maritime Industry he was honored, at his passing in 2018, with a memory tile at the Seattle Fisherman’s Memorial.
