Sinkuleep Service Company is a Native-owned project management and owner's representative firm led by John MacClain — three decades of casino leadership, deployed on behalf of the tribe, not the contractor.
Owner & Consultant, Sinkuleep Service Company. Enrolled member, Confederated Tribes of the Colville Reservation.
John MacClain started his gaming career in the spring of 1996, dealing blackjack. Within a decade he sat on his tribe's Board of Directors, eventually rising to Chairman — the top business seat on the Colville Reservation, responsible for every enterprise the tribe owned and operated.
He caught two of Indian gaming's biggest growth waves firsthand: California's hyper-growth after Proposition 1A, and Oklahoma's after Class III gaming was approved. That timing, paired with senior roles at gaming operations from Washington to New York, gave him a working knowledge of best practice from the country's largest Indian gaming markets — knowledge he now brings home to Omak.
"The most important part of construction is staying on time and on budget — held together by a master schedule and costs that match project progress, from day one to closeout."
Sinkuleep Service Company was formed in 2019 and has held Colville Title 10 certification since. It is 100% tribally owned and networked with a bench of qualified professionals who bring decades of combined casino construction experience and involvement in well over a billion dollars of gaming projects nationwide.
Sinkuleep Service Company represents the owner — never the general contractor — at every stage of gaming facility development. Services scale to the project, from a single feasibility study to full turnkey delivery.
Master planning and feasibility work that keeps the project grounded in what the market and the budget can actually support.
Principal point of contact between the architect, general contractor, subcontractors, and vendors — with an open book on cost and schedule.
Hands-on experience implementing Tribal Preference and TERO programs, and integrating Native-owned businesses through design and construction.
Staffing, systems, and soft-opening support so the facility is fully operational the day construction ends.
A career spent almost entirely inside Indian Country — general manager and executive roles across Washington, Oklahoma, New York, Oregon, and California.
