From Humble Beginnings to Industry Leadership

Our founder, embodies the spirit of determination and service. Raised in a family of entrepreneurs, he watched his father build businesses from the ground up—a lesson that deeply shaped his values of grit, resilience, and community contribution.

Professional journey began in the financial sector at just 18, when he joined HSBC. There, he developed a talent for structuring large-scale financial models. But our founder had a bigger dream—to build things that people could see, touch, and use. This ambition led him to pivot into large commercial construction, designing and managing massive call centers and corporate environments for national brands.

Over the next two decades, climbed the ranks, becoming CEO, COO, and VP of several national firms. His career evolved from finance to healthcare infrastructure, where he played a key role in launching everything from small clinics to expansive Ambulatory Surgery Centers across the United States.

Eventually, found his passion in HVAC—a field that combined his love for engineering, systems, and improving everyday lives. Refocused his energy on growing Sigma Air Heating & Cooling, scaled the company into a top-tier HVAC provider for the multifamily and residential sectors across Texas and beyond.
