About Dane Santibanez
Owner of SZANCO INC · Electrical expertise · Project management · Construction & maintenance service
With more than 13 years of experience across electrical work, construction, project management, and facility maintenance, I founded SZANCO INC to deliver dependable, well-managed construction and maintenance services.
My career began in the electrical trade before I moved into project management and construction administration, gaining experience in planning, coordination, documentation, and project support. I later returned to the electrical field and began working in airport maintenance as an electrician.
Professional Experience
- Electrician
- Project Management and Construction Administration
- Airport Maintenance Electrician
- Lead Electrician
- Supervisor
- Assistant Manager for General Maintenance Operations
- Maintenance Operations Manager for Passenger Boarding Bridges and Baggage Handling Systems
I oversaw the maintenance and operation of critical airport equipment, coordinated projects, and supported day-to-day facility operations. That background shapes SZANCO INC's approach: hands-on knowledge, organized management, clear communication, and practical solutions for every project.
I founded SZANCO INC on February 28, 2023, initially providing construction-administration and project-support services. After receiving my contractor license on December 9, 2025, I expanded the company to directly provide construction and maintenance services.
