OUR STORY
Family-Built.
Process-Led.
“We don’t just manage projects — we take full ownership of your vision, from the first conversation to the final walk-through.”
SionCorp was founded on a simple belief: property owners deserve more than just a contractor, they deserve an independent, trusted partner who brings analytical precision to every single decision. Powered by a foundational background in civil engineering and over 35 years of professional oversight experience in South Florida, our family-owned company expertly coordinates the entire project ecosystem.
We do not act as the manual general contractor, architect, or structural engineer. Instead, we are your dedicated advocate. We hire, align, and manage the best vetted specialists on your behalf, protecting your budget, streamlining your permits, and ensuring every milestone meets an elite standard of excellence.
Whether you are brainstorming a luxury gut renovation in Coral Gables or preparing a commercial tenant buildout in Brickell, you only need one partner to guide you from concept to handover. Our family is on your side of the table.

Our Proven Process
A clear, accountable workflow refined over three decades of South Florida project coordination.
We conduct an in-depth client meeting and comprehensive project walkthrough to capture your initial vision, design ideas, and desired scope of work. We analyze the existing space or site conditions to map out your core goals right from day one.
We develop an initial project budget and pricing framework before design teams begin drafting. Once financial guardrails are set, we help you select and align the ideal architects and engineers, ensuring their blueprints match your target budget.
We aggressively audit all architectural and MEP drawings as they are developed. Our team then prepares, submits, and manages the entire permit-running process, navigating city, county, and HOA corrections to secure approvals without delays.
We mobilize the project by serving as your daily eyes and ears on-site. We coordinate the general contractor and subcontractors, track schedule milestones, verify material logistics, and ensure that workmanship matches the approved plans.
We manage the entire closeout phase, leading the final municipal inspections and securing final approvals. We execute a rigorous final punch-list review with the builders, close out all vendor accounts, and hand over a completed project to your total satisfaction.
THE DIFFERENCE
Why SionCorp
Architects blame engineers, engineers blame general contractors, and the project stalls while you pay the price.
We manage and unify the architects, engineers, and builders. You have one number to call – ours.
Unchecked contractor change orders and inaccurate early estimates drain your capital mid-project.
We price and audit the scope of work before construction starts, protecting your capital from day one.
Months wasted sitting in municipal building departments dealing with endless local code corrections.
Decades of experience navigating Miami-Dade, Broward, and Palm Beach county agencies to secure fast approvals.
If you aren't on-site daily checking the technical details, corners get cut and quality suffers.
We apply an analytical, engineering-level standard of oversight to ensure execution matches architectural intent.
