Dan Pierson

Senior Vice President

Mr. Pierson began diving for Global in 1992, working as a diver/tender, saturation diver, Dive Supervisor and Dive Superintendant before moving into management roles, first as Asset Manager, then Vice President of the Pacific Northwest Region. He was appointed Vice President of Operations in 2014, and is responsible for overseeing all of Global’s regional offices as well as corporate asset management. Mr. Pierson earned his commercial diving certificate from the Divers Institute of Technology in 1991 and honed his skills working in the Gulf of Mexico.  He grew up on the water and has been involved with recreational boating and diving all of his life, and it continues to be a passion of his today.  Mr. Pierson says although he never wanted to grow up and take an office job (“You miss one meeting and your future is planned for you…”), he feels very fortunate to have worked with so many incredible people over the years, both in the field and in the office. “Global has come a long way during my time here, and I’m excited to see where we take it next.”
