Most valuable lesson
“In life and business, we never lose. Either we win or we learn. Life and business are not zero-sum games. We win, and when we don’t, we learn. Both paths lead to growth, resilience and a richer tapestry of experiences.”

Advice for your 18-year-old self
“The current state of your underprivilege will be your greatest asset in the future. Keep developing your skills and continuously shaping the person you want to become.”

Advice for future 40 Under 40 honorees
“Be seen and be present. If you are the only one who knows how great you are, it is a disservice to you and your future self.”

First job and lesson learned
“Server at Connie’s Cafe in Santa Rosa, Texas, my seventh grade year. Lesson: Those who serve for the benefit of others gain the most in life. That cafe was a local favorite for community leaders, and this lesson was shared by the mayor who had been in office for over 20 years. Years later, he wrote a fantastic recommendation letter for my acceptance to a prestigious leadership summer camp.”

Professional inspiration
“Marcus Aurelius faced numerous challenges. Despite these adversities, he maintained a stoic mindset, emphasizing that external events do not define our happiness. His resilience teaches us to stay composed and focused even in turbulent times.”

Top challenge facing Arkansas
“Establishing ourselves as a premier choice for both businesses and families relocating to our area from other markets. Arkansas faces the critical challenge of positioning itself as an attractive destination for businesses and families seeking relocation. By fostering an environment conducive to growth, offering robust infrastructure, and emphasizing quality of life, we can entice newcomers and drive economic prosperity.”

Learning from a mentor
“Mark Hill from MKP Inspired. His exceptional coaching facilitated my comprehension, conviction and subsequent alignment with Peter Drucker’s renowned phrase: ‘Culture eats strategy for breakfast.’ You can have the best plan, and even the best people, but if the culture of the business does not breed growth, innovation, leadership, positive synergy and direction, it is destined to fail.”

Professional “aha” moment
“Innovate and thrive. By strategically integrating our own metal fabrication facility into our roofing business, we recognize the potential benefits across multiple dimensions. First, this move enhances our market position by allowing us to offer comprehensive solutions — customized roofing systems with in-house fabricated metal components. Second, vertical integration streamlines our supply chain, ensuring greater control over quality, lead times and costs. Third, this synergy fosters business growth as we expand our service portfolio and attract a broader clientele. Ultimately, this strategic innovation positively impacts our bottom line by optimizing operational efficiency and capturing additional revenue streams.”

Career dream as a child
“Becoming an architect. Design and architecture have driven my imagination for decades. While I am not an architect now, I work with many in the roofing space and appreciate their skills and experience.”

Most fulfilling career moment
“Seeing our employees reach their personal goals of homeownership and having their kids say thank you.”

Making Arkansas more attractive to young professionals
“Leadership training cohorts and access to more opportunities for growth through consistent networking events statewide that bring the entire state together.”

Best thing about Arkansas
“The opportunities for business and personal growth are endless while living in a diverse state that offers such a great quality of life.”

Where you see yourself in 10 years
“Preparing the company for succession and entering the exit strategy of for-profit business.”

How you define success
“The ability to make a positive impact on people while altering the trajectory of lives long after we are no longer alive.”
