About Martin Ottaway Van Hemmen & Dolan, Inc.
Martin Ottaway Van Hemmen & Dolan, Inc. provides expert witness services and marine consulting to the U.S. Department of Justice as a prime contractor under full-and-open, non-set-aside purchase orders. The firm operates as a for-profit corporate entity based in Tinton Falls, New Jersey, and delivers litigation support and maritime subject matter expertise on a time-and-materials basis, with no subcontract footprint in its federal profile.
The customer base is heavily concentrated within the Department of Justice. The firm's 45 awards span eight distinct federal agencies, but 93% of recent awards fund DOJ work — specifically the Environment and Natural Resources Division (18 awards, $845 thousand combined potential value) and the Civil Division (17 awards, $389 thousand combined potential value), with smaller activity through DOJ's US Attorney's Offices (4 awards, $47 thousand). Two additional awards from the Department of Transportation Maritime Administration, one from the Army Corps of Engineers Engineer Research and Development Center, and one from Navy Military Sealift Command round out the customer set. The source material indicates the vendor has over 100 years of experience assisting maritime industry clients and has held a long federal history — the earliest award in the record dates to 1992.
Work is categorized primarily under All Other Legal Services (NAICS; 20 awards) and Engineering Services (17 awards), with the vast majority of individual awards flagged as Support-Professional: Expert Witness (36 awards). Representative recent work includes a $51.4 thousand purchase order from DOJ Civil Division for expert witness services (awarded May 28, 2026, performance through December 31, 2028), a $102.4 thousand purchase order from the Environment and Natural Resources Division for expert witness services on environmental law and policy matters (awarded July 21, 2023, performance through April 30, 2028), and a $42.9 thousand purchase order from DOJ Civil Division for expert witness services supporting maritime and environmental technical assessments (awarded June 27, 2025, performance through December 31, 2027). The combined potential value across all 45 awards is $1.4 million, with obligations matching that figure. Award velocity has been modest and variable — three awards in 2021, two in 2022, four in 2023, one in 2025, and two in 2026 — with two awards (combined potential value $145 thousand) facing ultimate completion inside the next twenty-four months and therefore subject to recompete.
