Chuck Mitchell was born in Los Angeles in December 1940 and moved to San Diego in 1947. He grew up in Point Loma, attending Cabrillo Elementary School, Dana Junior High, and Point Loma High School. His father was a mechanic who owned his own garages, which led to Mitchell spending a lot of time working on cars and developing a curiosity about how things work. This curiosity has been a driving force throughout his life. In the early 1950s, Mitchell and his family moved onto a boat at Jim Underwood's Landing, the first marina on Shelter Island.

Chuck Nicklin, a renowned diver and underwater cinematographer, was born in Massachusetts and moved to San Diego in 1942 at the age of fourteen. His father was in the Navy and was reassigned to San Diego during World War II. Despite his initial reluctance to move, Nicklin fell in love with San Diego and decided to stay even when his father was reassigned back to Boston. Nicklin graduated from Point Loma in 1945 and began his journey into the world of diving as a teenager, exploring the waters around Sunset Cliffs and La Jolla Cove.
