Harry is a Marine Surveyor and Marine Engineering professional with 25 years of hands-on experience across the maritime industry — shipyard operations, vessel engineering, construction and repair, oil spill response, and regulatory vessel inspections.

His career began in 2004 with the U.S. Coast Guard as a Small Boat Engineer and Maritime Law Enforcement Officer. From there, Harry came up through the hawsepipe — working as a marine mechanic on recreational and commercial vessels, then as port engineer at a local shipyard constructing tractor tugs and handling a wide range of vessel repairs, before transitioning to chief engineer aboard an oil spill response vessel.

In 2018, Harry entered the marine insurance industry as a surveyor, and was fortunate to be mentored by an industry legend in his twilight years in the Pacific Northwest. Harry's surveying journey led him to work for global insurance TPA conglomerates such as Charles Taylor and Sedgwick.

What you can expect

OMNI is a one-person practice, and that's the point. When you reach out, you're talking to the surveyor — not a call center, not a coordinator. Here's what that means for you.

You work directly with Harry from the first call through the final report — truly bespoke. We value your trust and a personable business relationship.
One point of contact who knows your file inside and out — with straightforward billing to match. No file-opening charges, no administrative percentage added to the invoice; fees and expenses are quoted up front and itemized.
Every engagement is shaped around your vessel and your unique situation — no templates. We take pride in producing comprehensive reports that are analytical and thoughtfully organized for our clients.
Clear, plain-language communication at every step, so you always know where things stand — fast responses, and always willing to pick up the phone, even for a quick question.
What We Offer

In 2026, Harry founded OMNI Marine. The word Omni — Latin in origin — means "all" or "every." The wide array of experience and exposure gained throughout his career makes him a unique marine surveyor, with a catalogue that ranges almost all or every.
