About Green Feet Enterprises, L.L.C.

Written by GovTribe AI ·

Green Feet Enterprises, L.L.C., doing business as S.e.i., is a service-disabled veteran-owned small business and SBA-certified 8(a) program participant based in Barrington, New Hampshire, that provides tactical medical training and instructor-led operational training courses to military and federal agencies as a prime contractor, competing predominantly under small-business set-asides on a combined $7 million in recent prime awards.

S.e.i. is a sole proprietorship, minority-owned and Hispanic American-owned, with SBA certifications as an 8(a) Business Development Program participant (expiring July 16, 2032), a service-disabled veteran-owned small business (expiring July 16, 2028), and a self-certified small disadvantaged business. The vendor's capability portfolio centers on Tier 1 Tactical Combat Casualty Care (TCCC) training, paramedic recertification, medical refresher instruction, and generalized tactical training delivery. Representative work includes a $74,900 purchase order from Air Force for Tier 1 TCCC training for 250 personnel at Mountain Home Air Force Base, Idaho in July 2024; a $21,800 purchase order from Air Combat Command for paramedic re-certification training for the 38th Rescue Squadron at Moody Air Force Base, Georgia; and a $27,394.59 purchase order from the U.S. Secret Service (awarded June 5, 2026) for a four-day Tactical Medical Operators Course at Epping, New Hampshire, accommodating up to 12 students with MARCH skills, advanced airway, pharmacology, and thoracic trauma management curriculum.

Customer concentration is heavily skewed to Air Force commands. The Department of the Air Force Air Combat Command accounts for 19 awards ($2.7 million combined potential value) and dominates the award-count ranking at 53% of recent work; when the Air Force Space Command's $4 million blanket purchase agreement is included, Air Force commands represent 94% of combined potential value across the portfolio. United States Special Operations Command places nine awards ($86 thousand combined potential value) but in much smaller unit values. Air National Guard and Air Mobility Command round out the active set, with the Secret Service representing a single non-Air Force touch.

S.e.i. holds two significant Air Force indefinite delivery vehicles: a $4 million multiple-award Blanket Purchase Agreement with Air Force Space Command supporting the 920th Rescue Wing (awarded December 23, 2024, expiring January 12, 2029) and a $2 million single-award Indefinite Delivery Contract with Air Combat Command (awarded November 13, 2024, expiring November 12, 2029). Under the $2 million IDC, Air Combat Command issued 11 delivery orders between January and October 2025 valued between $5,280 and $85,412, with cumulative obligation of approximately $336,552, concentrated at Davis-Monthan Air Force Base, Arizona and Imperial Beach, California. The $4 million BPA has generated at least one delivery order of $82,608 for medical refresher training at Patrick Space Force Base, Florida (September 15, 2025).

Activity has grown from one award in 2018 to nine in 2025, with four awards recorded in 2026 year-to-date. The portfolio is 100% prime work with no recorded sub-awards. NAICS concentration is heavily weighted to "All Other Miscellaneous Schools and Instruction" (31 of 36 awards), with PSC coding dominated by "Education/Training — Other" (23 awards) and "Education/Training — Combat" (4 awards). Approximately $5.9 million of the $7 million combined potential value remains unobligated, with the bulk concentrated in the two Air Force IDVs and anchored by the $4 million BPA awarded in December 2024.
