Marathon Engineering & Environmental Services

What Marathon Engineering & Environmental Services does

Marathon Engineering & Environmental Services was a private professional consulting firm founded in 1997 and headquartered in Swedesboro, New Jersey. The firm specialized in civil engineering, environmental permitting, and environmental investigations, serving clients who required engineering consulting and regulatory support services. It operated as a small consultancy with 11-50 employees and maintained a web presence at marathonconsultants.com. No information is available regarding ownership structure, leadership team, funding history, or financial performance.

Per its own website, Marathon Engineering ceased providing professional consulting services in May 2026. The company's web presence now consists solely of a redirect page directing all engineering service inquiries to PS&S, which appears to have absorbed Marathon's client relationships and service offerings under a referral or transition arrangement. The company has no active marketing channels, no published pricing, no disclosed revenue, no product portfolio, and no documented customer base. The underlying cause of the cessation — whether a wind-down, acquisition by PS&S, founder retirement, or market exit — is not disclosed in the available data.

From an investment perspective, Marathon Engineering is no longer an operating entity. There is no revenue stream to underwrite, no product roadmap to assess, and no competitive position to evaluate. The only residual signal of strategic significance is the transition relationship with PS&S, which is documented as a core channel-partner arrangement where PS&S is positioned as the successor organization for Marathon's engineering consulting work.
