Castillo maintains a consistent working relationship with Regency Consulting Inc., a primary contractor engaged in the supply and integration of electrical distribution systems for healthcare facilities. Her procurement approach emphasizes reliability, technical compliance, and long-term operational readiness, favoring vendors with demonstrated expertise in medical-grade electrical infrastructure. While she collaborates primarily with a single core contractor, her engagements reflect a strategic preference for established partners with proven experience in federal healthcare environments and adherence to NFPA and OSHA standards. Castillo’s contracting activity shows no use of socioeconomic set-asides, with 100% of awards issued under full and open competition. This reflects a procurement strategy prioritizing technical capability and mission-critical performance over socioeconomic classifications, aligning with the agency’s urgent need for specialized, high-reliability equipment in isolated locations where delays are not feasible. Her primary procurement focus is on NAICS 335313—Switchgear and Switchboard Apparatus Manufacturing—indicating deep expertise in electrical distribution systems for healthcare facilities. She procures medium- and low-voltage switchgear, circuit breakers, busways, and associated control systems designed for continuous operation in off-grid or power-sensitive environments. Her technical domain centers on ensuring medical facilities maintain stable power infrastructure to support life-saving diagnostic and surgical equipment.
