Jerry Kemler is the man you call on when you need things done now, and done right! He is literally a "jack of all trades", and is master of all. As a licensed captain, commercial diver, certified diesel mechanic, and certified welder, there isn't anything that needs doing on an expedition that Jerry can't handle. He started early in life with hands-on experience, working his way up to Supervisor of Operations for a large marine construction and salvage company. He continued to develop his skills working for other commercial dive companies, treasure hunting companies, and as a yacht captain. In all these endeavors he was known for his organizational expertise, and his talents in the fields of cost analysis, equipment management, project logistics, and site supervision. Jerry has participated in more than 30 research and recovery expeditions and has a reputation for being the man who can find underwater what others have missed.

Jerry is also a steward of Mother Earth, shown in his involvement with a non-profit Eco Lodge and Eco Foundation in Costa Rica, whose profits go toward creating a marine sanctuary on the country's Pacific coast. Jerry has been involved since the beginning in 1998, clearing jungle, building, installing, administrating, and today the lodge is world-famous. Whenever he is not treasure hunting, he spends as much time in Costa Rica as possible. He became involved with OCS in 2003. Time and again he has proven his worth through his many skills, toward the success of every project.
