One partner for the entire facility.
OFS primes the contract and is the single point of accountability — we self-perform where we have crews and manage a vetted network of cleaners, landscapers, pest control, and security elsewhere. One contract, one invoice, one report. Miss a standard and we make it right within 24 hours.
