Competing in Business, United in Faith:
God-Centered Leadership with Sam Pappas & Marty Hepp

In a marketplace where rivalry often overshadows relationship and competition can quietly erode connection, two leaders stand out as powerful reminders of what God can do when His people put the Kingdom first. In an industry known for high stakes, intense bidding, and constant pressure to outperform, Sam Pappas and Marty Hepp have chosen a different path — one marked by integrity, honor, and a deeply rooted biblical worldview.

Rather than allowing business competition to create distance or distrust, they have cultivated a genuine, Christ-centered friendship that has strengthened not only their personal lives but the cultures of their organizations. Their relationship is a testimony to the truth that when leaders place faith above profit and people above position, competition becomes secondary to calling.

Sam and Marty demonstrate that it is fully possible — and profoundly powerful — to run thriving, influential companies while still cheering on a brother in Christ across the street. Their story shows how Kingdom leadership transforms not just workplaces, but hearts, revealing a way of doing business that honors God, elevates others, and stands as a witness to the world.

Meet the Speakers

Martin Hepp
Marty Hepp has dedicated his life to civil engineering and to honoring God in every aspect of his work. Growing up in Fairview, Oklahoma, he pursued his degree in Civil Engineering at the University of Oklahoma and began his career in 1984 at what would become CEC Corporation. Over the decades, Marty’s leadership has helped CEC grow into one of the largest Oklahoma-based engineering firms with more than 250 team members and multiple offices across Oklahoma and Texas. His clients span major public agencies and private enterprises, and under his stewardship, the firm has become known not only for technical excellence but also for a faith-based culture grounded in biblical principles.

As a long-time member of Crossings Church, Marty serves as Chair of the Board for the Christian Business Men’s Connection (CBMC) nationally and leads local discipleship efforts, helping men integrate faith and work. At home, he and his wife Donna of over 40 years enjoy family life, cycling, and making disciples of Christ.

Sam Pappas
Sam Pappas is the President of MacArthur Associated Consultants, a respected civil engineering and surveying firm headquartered in Oklahoma City. As a leader in the industry, Sam directs the firm’s strategic vision while championing a culture of excellence built on honoring God in the workplace.

Beyond his role at MacArthur Associated Consultants, Sam is deeply involved in CBMC Oklahoma, serving on the Area Leadership Team and leading Connect3 faith groups for business professionals. His involvement reflects his commitment to discipleship and to helping others see their workplace as a mission field — where everyday decisions and relationships point back to Christ.

A Kingdom-Centered Friendship in a Competitive Field

While Sam and Marty lead their respective civil engineering firms — companies that operate in the same industry and sometimes compete for business — their relationship is a testament to the truth Jesus taught in John 13:35: “By this everyone will know that you are my disciples, if you love one another.” Their friendship models kingdom values over competition. Instead of rivalry dividing them, their shared commitment to Christ unites them in purpose and mutual encouragement.

Their involvement with CBMC — an organization focused on helping men integrate their faith with their work, build disciples, and lead like Christ in the marketplace — has been instrumental in shaping how they lead and relate to others across industries.

As leaders, they demonstrate that:

• Faith shapes culture: Both men strive to embed biblical principles into daily business practices, showing that honoring God in the workplace isn’t just an aspiration — it’s a lived reality.

• Relationships matter: Their friendship underscores the importance of spiritual community, accountability, and mentoring — especially in competitive fields.

• Business can be ministry: For Sam and Marty, business is not just about profit or position; it’s about people, purpose, and proclaiming Christ through actions, service, and leadership.
