Chamberlin Steve

Chamberlin Steve, doing business as Tulsa Counseling Services, is a sole-proprietorship operator of community mental health and substance-use treatment services for federal inmates, delivering all work as a prime contractor to the Department of Justice Bureau of Prisons with no set-aside designation or subcontracting footprint. The vendor operates from Tulsa, Oklahoma, and has held a sustained contracting relationship with the Bureau of Prisons Central Office spanning at least fifteen years, with firm fixed-price delivery orders issued on a semi-annual (six-month) cycle.

Tulsa Counseling Services' entire customer base and award portfolio consists of a single federal customer: the Department of Justice Bureau of Prisons Central Office accounts for all 27 awards and the full $3.1 million in combined potential value across the vendor's tracked history. The vendor sits on two Bureau of Prisons indefinite delivery contracts — DJBCTS503 (19 task orders, $982 thousand combined potential value) and DJBTDAT184 (6 task orders, $275 thousand combined potential value) — and places all work under these two parent vehicles. Recent delivery orders include a $113,010 contract awarded April 1, 2026 (completion September 30, 2026), a $113,010 contract awarded October 1, 2025 (completion March 31, 2026), and a $136,495 contract awarded April 1, 2024 (completion September 30, 2024). Individual order values range from $34,804 to $136,495, with semi-annual issuance cycles (April and October award months) and six-month performance periods that have remained consistent since at least 2022. The source data classify all 27 awards under NAICS 621420 (Outpatient Mental Health and Substance Abuse Centers) and PSC code H064 (Social Rehabilitation).

Activity has remained flat across the last five years at two awards annually, with only one award ($113 thousand) reaching completion inside the next twenty-four months and therefore facing recompete exposure in that near-term window. Combined dollars obligated across all awards total $960 thousand, representing 31 percent of the combined potential value, indicating that the vendor has invoiced roughly one-third of the contracted ceiling across its portfolio. The vendor operates with no recorded subcontracting relationships and competes in a full-and-open posture rather than under any set-aside category.
