Charles S. Szabo, M.d., Inc.

Charles S. Szabo, M.D Inc., doing business as Charles S Szabo MD Inc., is a for-profit medical consulting firm based in Mill Valley, California that provides expert witness testimony, medical record review, and litigation support services to federal law enforcement and justice agencies as a prime contractor, competing on a full-and-open basis without set-aside designations. The firm leverages Dr. Charles S. Szabo's professional medical credentials to serve the Department of Justice and its components, with typical billing at approximately $400 per hour for medical record review and expert services.

Charles S. Szabo, M.D Inc. operates exclusively as a prime contractor (100% of awards across 28 total federal awards) with no subcontract footprint. Customer concentration is extreme and bifurcated: the Drug Enforcement Administration accounts for 22 awards and $235 thousand in combined potential value, while the U.S. Attorney's Offices account for 6 awards and $160 thousand, together representing 100% of the firm's federal work. The firm has been registered in the System for Award Management since June 2015. All awards are full-and-open purchase orders without set-aside designations; the firm does not compete in 8(a), HUBZone, SDVOSB, WOSB, or other socioeconomic categories.

Capability work is narrowly scoped to expert medical services. Recent DEA awards include a $30 thousand labor-hours purchase order for subject matter expert services (effective July 8, 2026 through July 7, 2027, performed in Oakland, California), a $30 thousand firm fixed-price purchase order for medical records review (October 30, 2025 through December 31, 2026, performed in Fresno, California), and a $46 thousand labor-hours purchase order for medical expert services including expert witness testimony and litigation support (May 2, 2025 through April 1, 2026). U.S. Attorney's Offices awards have ranged from $6,900 to $38,856.86 for expert witness services. The firm's NAICS profile reflects 18 awards under "Offices of Physicians (except Mental Health Specialists)" and a dominant PSC coding of 25 awards under "Support — Professional: Expert Witness."

Activity has been episodic rather than growth-oriented: five awards in 2021, one in 2022, two in 2024, two in 2025, and one in 2026 (as of mid-July). Combined potential value across all 28 awards is $396 thousand, fully obligated. Two awards with combined potential value of $60 thousand face ultimate completion within the next twenty-four months, representing minimal recompete exposure by scale. The firm's federal footprint is specialist and narrow: litigation support and expert witness services to DOJ agencies, with no diversification across civilian IT, defense, or other federal business lines.
