Green-Hill Lisa J

Green-Hill Lisa J, doing business as Green-Hill, Lisa, J., DR., is a sole proprietorship providing independent medical consultant services — primarily disability claim case file reviews — to the Social Security Administration as a prime contractor under Blanket Purchase Agreement call orders, operating on an unrestricted, full-and-open competitive basis with no set-aside designations.

Green-Hill is a minority-owned, woman-owned, and Black American-owned sole proprietorship based in Chicago, Illinois, under the ownership of Dr. Lisa J. Green-Hill. The vendor operates under primary NAICS 8111 (Offices of Physicians except Mental Health Specialists) and PSC Medical- Medical/Psychiatric Consultation. Green-Hill competes exclusively in unrestricted federal procurements; no set-aside category appears across the award footprint.

The vendor's customer concentration is absolute: 100 percent of the 19 awards and all $6.4 million in combined potential value are awarded by the Social Security Administration. Green-Hill holds two primary BPA vehicles with SSA for regional medical contractor services in Region 5 (Chicago). The larger vehicle, BPA 28321321AC0540015, carries $2.19 million in potential value and has generated ten call orders totaling $1.2 million; the second BPA, SS05164C037, has generated seven call orders totaling $263 thousand. Recent representative awards include a $213,840 call order (April 2026, performance through June 2027) for disability adjudication medical reviews, a $201,960 call order (July 2025, performance through June 2026) for independent case reviews and extended period of performance, a $160,380 call order (August 2024, performance through May 2025) for 1,620 independent case reviews, and a $155,331 call order (July 2023, performance through April 2024). The vendor has held this role consistently since March 2021; prior call orders have ranged from approximately $38,888 to $160,380.

Activity over the past five years has remained steady at two awards per year, with no growth trajectory. One award (the April 2026 call order, combined potential value $213,840) faces ultimate completion within the next twenty-four months and therefore sits in the recompete window. The vendor operates exclusively as a prime contractor with no subcontract footprint. Green-Hill's capability is narrowly scoped: medical case file reviews, independent medical assessments, and disability determination support work performed for SSA's Region 5 operations in Chicago, with no diversification across agencies, geographies outside Chicago, or service lines beyond medical consultation.
