Mark was born on September 27, 1957, in Iowa City, the son of Anthony and Edith Siperly Costello.
Mark made his career at MPW in several positions retiring as Operations Supervisor after 37 years in 2016. He never let his day job limit his lifelong ambitions of adventure on the high seas. He can be attributed to building bridges, underwater construction, nuclear reactor construction (Mason Jars and Spaghetti Noodles), Captaining the Pearl Button Paddle Wheel boat, entrepreneurship, and creating memories for all.
Captain Mark Costello, admired by many and loved by all who were lucky enough to know him. A pirate at heart, who blessed many lives both on land and sea.

His passion to work and dedication to his family and friends never wavered; even in his weakest moments he was the strongest man in the world. His legacy will live on through all that have had a chance to feel the impact of THE CAPTAIN MARK COSTELLO.
