Fuel delivery should be safe, reliable, and built around the people who depend on it.
Founded by the Marroquin family, Topped Fuel was created to modernize how fuel reaches the Gulf Coast and Crossroads communities that power this region.
From commercial fleets and construction equipment to marinas and residential customers, our mission is simple:
Santiago Marroquin brings a career shaped by service, responsibility, and a commitment to doing work that matters. Through his years in medicine, he has developed a deep appreciation for professionalism, trust, and the value of people’s time—principles that now help shape his vision for Topped Fuel.
For Santiago, Topped Fuel is both a business opportunity and a family endeavor. Building the company alongside his sons gives him the opportunity to share what he has learned throughout his career while supporting them as they develop their own experience, ideas, and leadership.
That family perspective also influences how Santiago views the company’s relationship with its customers. Topped Fuel was created to make fueling safer, more reliable, and more convenient—helping customers spend less time managing fuel and more time focused on their businesses, families, and priorities. For Santiago, that combination of service, relationships, and family is what makes Topped Fuel a meaningful next chapter.

For Julian, Topped Fuel represents an opportunity to apply that perspective while building something alongside his family.

Outside of work, Julian enjoys fishing, hiking, and spending time outdoors. That appreciation for the outdoors complements Topped Fuel’s connection to the Gulf Coast and the customers and communities the company is being built to serve.
