Chang Douglas

Chang Douglas, a sole proprietorship based in Geneva, Illinois, operates as a medical consultant service provider delivering independent case reviews of disability claim files for the Social Security Administration under blanket purchase agreements, competing in the full-and-open marketplace with no set-aside designations across its entire federal footprint.

Chang Douglas's capability portfolio is entirely specialized: medical consultant reviews of SSA disability claim case files to support the agency's disability benefits determination process across Region 5 (Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin). The vendor operates exclusively within the SSA's Medical Contractors program, conducting independent medical assessments and providing expert opinions to inform eligibility decisions. Recent call orders represent the standard work product—a $198 thousand BPA call awarded May 19, 2026, for independent medical case reviews with completion by June 30, 2027; a $31.68 thousand call awarded March 10, 2026, conducting disability claim file assessments; and a $212.85 thousand call awarded July 1, 2023, for regional medical consultant services in Region 5 through April 30, 2024.

Customer concentration is absolute and undiversified. All 32 recent awards (100% of the portfolio) fund Social Security Administration programs. The vendor has no secondary agency relationships and no subcontract work; it operates as a pure prime contractor exclusively to SSA.

Chang Douglas holds three active BPAs. The largest, BPA 28321321AC0540009, carries an $2.19 million ceiling with 11 recent task orders totaling $1.6 million in combined potential value. BPA SS05164C006 supports 10 task orders worth $1.4 million combined, and BPA SS051140126 carries 8 task orders totaling $664 thousand combined. Individual call orders have ranged from approximately $69.3 thousand to $257.6 thousand.

Activity has remained flat at two awards per year across the past five years, with one award due to complete within the next twenty-four months ($198 thousand). The vendor's combined potential value across all recent awards totals $8.9 million, with $3.7 million obligated to date (41% of potential value), reflecting the billing cadence typical of SSA medical consultant call orders issued throughout the year.
