Dorothy ANN Leong, M.d., P.a.

Dorothy ANN Leong, M.D., P.A., a woman-owned, minority-owned, Asian-Pacific American-owned small business based in Dallas, Texas, provides independent medical case reviews and regional medical consultation services to the Social Security Administration as a prime contractor under full-and-open (non-set-aside) competition. The firm operates exclusively as a sole-source vendor to SSA, holding multiple blanket purchase agreements for disability claim file reviews and medical evaluation support across SSA's regional hearing offices.

Dorothy ANN Leong's customer footprint is entirely concentrated with the Social Security Administration: 58 of 64 recent prime awards (91% of the total) represent SSA task orders valued at $7.4 million in combined potential value. The vendor holds five active blanket purchase agreements with SSA, with the largest vehicle — BPA 28321321AC0640008 — supporting 15 task orders worth $2.6 million combined potential value and running through June 30, 2027. Two additional BPAs (SS06164C017 and SS10781160114) account for 16 and 17 task orders respectively, at $1.4 million and $475 thousand combined potential value. The vendor's work centers on two service categories: medical-medical/psychiatric consultation (35 awards) and support-professional services including expert witness testimony (13 awards), classified primarily under NAICS 621111 (Offices of Physicians except Mental Health Specialists).

Dorothy ANN Leong's recent work consists of recurring call orders under existing regional medical consultant agreements. Representative recent awards include a $421.9 thousand BPA call from SSA (awarded July 1, 2026) for disability adjudication case file reviews supporting the SSA's New York regional operations through June 30, 2027; a $445.5 thousand call order (awarded May 19, 2025) for independent case reviews from the Dallas regional hearing office; a $211.2 thousand call order (awarded July 3, 2024) for 2,275 independent case reviews at the Dallas office; and a $150.1 thousand call order (awarded December 14, 2023) for 720 independent case reviews. The vendor has consistently performed between 1,800 and 4,250 case reviews per call order and has delivered over 15,000 case reviews in prior award years. Activity has remained modest and flat over the past five years (three awards in 2022, four in 2023, two in 2024, three in 2025, two in 2026), with only one award (combined potential value $422 thousand) completing within the next twenty-four months, creating minimal near-term recompete exposure. The vendor does not subcontract and operates no parent contract vehicles or government-wide acquisition vehicles.
