What OgilvyEntertainment does

Hickman Consulting Services, LLC is a woman-owned professional consulting firm headquartered in Pittsburgh, Pennsylvania, delivering specialized natural resource advisory services to clients across the United States. The firm's core offerings fall into three integrated service lines: valuation of oil and gas, coal, minerals, and limestone assets; expert witness services for litigation in state civil, criminal, and federal courts; and royalty management for oil and gas holdings. Supporting capabilities include geotechnical consulting and the operation of an in-house Expert Witness Network that coordinates multi-disciplinary technical experts — petroleum engineers, reservoir engineers, operations geologists, geochemical experts, gas storage engineers, and gas storage regulatory specialists — to serve complex multi-expert legal cases through a single point of contact.

The firm is led by Jessica Hickman (geologist, 10 years' experience) and Josh Hickman (senior geologist, 25+ years' experience, licensed Professional Geologist in Kentucky, Pennsylvania, Tennessee, and Utah, certified CPG, with prior titles including Chief Geologist, Owner, President, CEO, COO, and Chairman). Customer segments span legal teams and law firms (primary), estates and trusts, energy companies and corporations, and US Government agencies, with engagements spanning expert testimony, asset valuation, and royalty administration. The technology footprint is human expertise-driven: no proprietary software, AI, or digital platform is disclosed.

Revenue is generated through professional services fees on project-based, custom-quoted engagements, often structured as multi-year contracts. Go-to-market is overwhelmingly referral-driven and relationship-based, relying on LinkedIn presence, professional organization memberships (International Institute of Mineral Appraisers, Energy Leaders Network), conference participation (SME MINEXCHA presentation in 2026), and direct outreach to legal teams and government agencies. There is no disclosed external funding, no institutional investors, and the firm operates as an independent consulting practice privately held by its two principals.
