Park Dietz & Associates, LLC

Park Dietz & Associates, LLC, doing business as Park Dietz & Associates Inc., is a for-profit subchapter S corporation based in Newport Beach, California, that delivers forensic psychiatric expert witness and mental health consulting services to the federal government exclusively as a prime contractor (100% of 142 awards) in full-and-open competition with no set-aside designations across its footprint. The firm operates without SBA certifications and competes across eleven distinct customer agencies, but customer concentration with the Department of Justice is extreme: the US Attorney's Offices alone account for 88 of the company's 142 awards and $3.3 million of its $6.2 million combined potential value, while the Criminal Division and Civil Rights Division add another $518 thousand and $380 thousand respectively, giving DOJ components roughly 74% of the combined potential value and 80% of award count.

Park Dietz & Associates has been registered in the federal contracting system since August 2003 and maintains a narrow, specialized capability portfolio: all 118 of the top NAICS assignments across the footprint fall under "All Other Legal Services," and 133 of the top PSC code assignments are tagged "Support—Professional: Expert Witness." The firm's scope centers on plaintiff and defendant mental health evaluations, forensic psychiatric analysis, competency reviews, capital charge consultations, and expert opinions, reports, and testimony to support federal litigation and prosecutorial efforts. Representative prime work includes a $341.5 thousand time-and-materials purchase order from the Civil Rights Division awarded March 31, 2023, with ultimate completion March 31, 2027; a $349.2 thousand purchase order from the US Attorney's Offices awarded January 23, 2023, through September 20, 2023; and a $131.2 thousand purchase order from the US Attorney's Offices awarded July 13, 2022, for forensic expert evaluation of a plaintiff's mental health capacity in a potential capital punishment case, with completion through June 30, 2026. The company's most recent awards are September 2026 ($55 thousand, DOJ Offices Boards and Divisions) and April 2026 ($18.9 thousand, US Attorney's Offices for expert witness services).

Award activity has remained relatively flat across the trailing five years, averaging 8 to 10 awards annually (2022 through 2025), with 2026 tracking at only 3 awards year-to-date. Twelve awards (combined potential value $857 thousand) face ultimate completion within the next twenty-four months, presenting recompete exposure. The firm operates exclusively on time-and-materials purchase order vehicles; it does not sit on any multi-award IDIQs, GWACs, BPAs, or agency-wide contracting vehicles. Combined dollars obligated across all awards total $6.9 million, representing 110% of combined potential value, indicating the vendor has invoiced beyond ceiling in some instances. Park Dietz & Associates maintains no subcontract footprint and does not serve as a subcontractor to other primes; all 142 awards are direct prime relationships with federal agencies.
