Chamberlin Steve

Chamberlin Steve, doing business as Tulsa Counseling Services, a sole proprietorship based in Tulsa, Oklahoma, delivers community mental health and substance-use treatment services to federal inmates as a prime contractor (100% of recent awards) on firm fixed-price delivery orders issued by the Department of Justice Bureau of Prisons Central Office. The vendor operates exclusively in the full-and-open market with no set-aside designations across its federal footprint.

Tulsa Counseling Services has maintained a sustained contracting relationship with the Bureau of Prisons spanning at least fifteen years, with semi-annual delivery order cycles — two awards per year have been consistent across the past five years. All work is performed directly from Tulsa, Oklahoma 74114, with no subcontracting footprint. The vendor's capability portfolio is narrowly specialized: substance use disorder treatment, mental health counseling, and behavioral health interventions for incarcerated individuals within a community-based setting. Representative work includes a $113,010 delivery order (October 1, 2026, through March 31, 2027) for community mental health and substance-use treatment services, a $136,495 award (April 1 through September 30, 2024) for substance use and mental health services, and a $44,855 delivery order (October 1, 2023, through March 31, 2024) for the same service category — all under the Bureau of Prisons Central Office.

Customer concentration is absolute: the Department of Justice Bureau of Prisons Central Office accounts for 100% of awards and 100% of combined potential value ($3.2 million across all twenty-eight awards in the source dataset). The vendor sits on two indefinite delivery contracts issued by the Bureau of Prisons: DJBCTS503 (20 task orders, $1.1 million combined potential value) and DJBTDAT184 (6 task orders, $275 thousand combined potential value). One award ($113 thousand ceiling value) reaches ultimate completion within the next twenty-four months, representing the only recompete exposure in that window. Combined dollars obligated across all awards total $989 thousand, representing 31% of combined potential value, consistent with the firm fixed-price delivery order cycle structure. The vendor's federal footprint is entirely anchored to correctional mental health and substance abuse treatment services, with no diversification across customer agencies or service categories.
