Started diving in 1964, was certified at Stanford University in 1966. Became instructor in 1973 and shortly after bought Aquarius Dive Shop in Monterey, CA. Owned dive charter boat. Sold the store in 1984 and moved to Washington State in 1986. Now dive for fun and lead some trips to Hawaii and British Columbia. From 1975 to 2000 I took underwater stills, since then taking video; now in HD. Have published several clips on YouTube - search scubajam. Sell some stock video and clips, including to History Channel for Monster Quest.
