Our Team

01.
Technical Depth

25 years performing Phase I and Phase II site reconnaissance. 20 years delivering PCAs for residential, commercial, and industrial assets. We've seen every property type, every condition, and every reporting standard — and we know how to deliver.

02.
Objective Analysis

We have no stake in your transaction outcome. Our role is to give you accurate, unbiased data — whether that means flagging a deal-killer or confirming a clean bill of health. That objectivity is what clients come back for.

03.
Local Insight, National Standards

Headquartered in Lehigh County, Pennsylvania. Experienced in ASTM E1527-21, ASTM E2018, HUD MAP, Fannie Mae, and multiple individual client protocols. We combine Eastern PA market knowledge with the rigor national firms require.

04.
Reporting That Drives Decisions

A report is only valuable if you can act on it. We write clearly, flag what matters, estimate real costs, and structure every deliverable to support your next step — whether that's negotiating, walking away, or closing with confidence.

Founded on Field Experience.

Built for the Long Term.

Sedora Consulting was formed in 2013 by Mark Sedora after more than a decade building expertise in environmental site reconnaissance and property condition assessments for some of the nation's leading consulting firms. The goal was straightforward: bring institutional-grade technical rigor to a broader client base — including the regional investors and local lenders who often couldn't access that level of expertise.
Today, Sedora Consulting continues to support national firms as a trusted regional partner across Lehigh Valley and Greater Philadelphia, while also serving the growing community of commercial investors who understand that a thorough pre-purchase assessment is the most cost-effective insurance available in real estate.

Most people struggle with this. "
