Who is Marc Interial?

Marc Interial is the President of Growth and Development at Process Technical Services (PTS), a leading operational services firm serving the global oil and gas, LNG, petrochemical, and industrial sectors. Based in Spring, Texas, he brings more than 25 years of hands-on experience across offshore, FPSO, and LNG environments, having supported some of the world’s most recognisable operators across four continents.

A certified Project Management Professional (PMP), Six Sigma Green Belt, and Prosci change practitioner, Marc leads with a philosophy rooted in integrity, operational discipline, and the belief that people are the foundation of every high-performing system. He also serves on the SAVI Advisory Council, supporting military veterans in their transition to civilian leadership roles.

Before his time in executive leadership, Marc spent fifteen years working on major energy projects across Angola, Korea, Alaska, Brazil, Israel, Ghana, South Africa, and the Gulf of Mexico, supporting operators including Chevron, Shell, BP, Statoil, ENI, Hess, Inpex, Anadarko, ConocoPhillips, and Transocean. His career is not a story of titles accumulated. It is a story of standards maintained.

The House Where Responsibility Was Demonstrated

Before anyone teaches you what leadership is, life has usually already shown you. Not through theory or case studies, but through the people in the rooms you grew up in. The ones who rose before the sun and came home after dark. The ones who never made a speech about responsibility because they were too busy living it.

For Marc Interial, those values took root early, in a household where showing up was not a virtue to aspire to but simply the baseline. His father was a man who worked with his hands. He came home exhausted, set firm expectations when discipline was needed, and reserved very little time for himself. Yet he made it to every game, every season, without exception. That consistency left a deeper imprint on Marc than any formal lesson could have.

The household ran collectively. Marc cleaned toilets alongside his mother in apartment buildings she managed. His grandmother helped hold things together while others kept momentum going. Responsibility was not framed as sacrifice. It was framed as participation.

“Responsibility in our house was never discussed. It was demonstrated. My father believed that your word mattered and that excuses were a luxury you couldn’t afford.”

By thirteen, Marc had already held several jobs. He cut weeds in crop fields alongside migrant workers, sold newspaper subscriptions, mowed neighborhood lawns, and took a night-shift dishwashing job at a truck stop. None of it was glamorous. All of it was formative. What he absorbed was not just a work ethic but a worldview: show up even when you are tired, take pride in unglamorous work, and respect the people who grind quietly in the background.

Service, Structure, and the Making of a Professional

After those early working years, Marc took a path that would sharpen every instinct he had developed at home. He enlisted in the United States Navy and served aboard the USS Carl Vinson (CVN-70), one of the most operationally demanding environments a young person can enter. Accountability was not a concept to discuss. It was the operating standard.

The Navy gave Marc something beyond discipline. It gave him an appreciation for systems, for the chain of consequences that follows when someone cuts a corner or misses a step. In environments where the margin for error is thin, the culture either holds or it does not. He learned early which kind of culture he wanted to build.

After his service, Marc pursued his education with the same consistency. He earned an Associate of Arts from Lone Star College, a Bachelor of Science from the University of Houston-Downtown, and ultimately two Master’s degrees from the University of Houston: one in Technology Project Management and one in Human Resource Development. That dual focus on systems and people would prove to be the defining combination of his professional approach.

His first steps into the energy industry came through Michael Baker International, where he spent eight years managing oil and gas projects and building the data management foundations that complex operations depend on. He then moved to Wood, progressing from Senior Manager to Delivery Manager over seven years, leading product lines and overseeing multi-service delivery across global assets. Marc was not building a career from the top down. He was building it from the ground up, the same way his father had taught him.

The Turning Point: When Motion Became a Warning Sign

For many executives, the defining moment arrives not in a boardroom but in a quiet confrontation with what the pace of their work is actually costing them. For Marc, that moment crystallised during a period of relentless international travel that would have tested anyone’s sense of proportion.

In a single month, his schedule took him from London to India, to Perth, to Colombia, and back to Houston, with barely a breath between each stop. He recalls sharing that itinerary with a flight attendant, someone whose entire profession is motion, and watching her expression shift. Even she thought the pace was excessive. When he eventually stepped back from that chapter, what followed was not immediate relief but clarity.

“Time won’t stop for you, so you must take the time to stop for yourself. It’s essential to pause and ask: Am I still aligned with what truly matters?”

That recalibration shaped how he approaches leadership today. Not with an obsession over constant activity, but with a deep respect for restoration and the quiet work that never appears on a schedule but determines everything about whether someone can sustain high performance over the long term.

Marc joined Process Technical Services in 2018, bringing with him two decades of hard-won operational knowledge. He progressed steadily from Senior Manager to Vice President of Operations, then Senior Vice President, and ultimately to his current role as President of Growth and Development. At each stage, his focus remained the same: strategy had to match execution, growth had to respect capability, and culture had to reinforce standards rather than quietly undermine them.

“True operational excellence requires creating a culture where safety and quality are never compromised for schedule or cost, and where leaders are willing to stop work, ask hard questions, and take accountability when something isn’t right.”

Impact Across Four Continents and Two Worlds

Before taking on executive leadership, Marc spent fifteen years supporting some of the most complex energy operations on the planet. His project portfolio is a testament to the breadth of his expertise: operations assurance and readiness for major LNG and FPSO assets, SEMS audits and corporate management system development, training and competency programmes, maintenance planning and CMMS implementation using Maximo, SAP PM, and JDEdwards, and the development of operating manuals and HSE management systems for assets entering service for the first time.

These were not advisory engagements from a safe distance. They were field-level assignments in environments where the cost of a shortcut is never hypothetical. Alongside his professional work, Marc also served as Vice Chairman of the TLIM Technology Division Board at the University of Houston, helping bridge the gap between industry experience and the next generation of technical leaders.

Today, Marc’s commitment to developing the next generation extends through his work with the SAVI Advisory Council, where he supports military veterans navigating the transition into civilian professional life. His advice to veterans reflects the same philosophy that has guided his entire career.

“The transition is not about changing who you are. It is about learning how to communicate your leadership in a new environment while staying grounded in the values that made you successful in the first place.”

Across every context, the same belief holds: talent deserves context, not erasure. Systems should adapt to people, not the other way around. And leadership, at its most enduring, is not about visibility. It is about the steady, consistent presence that gives others the foundation to do their best work.

Leading from the Ground Up: Building What Lasts

Marc Interial does not separate his professional philosophy from his personal one. Integrity, for him, is not a value written into a company handbook. It is an operational choice, made daily, visible in every safety decision, every hiring conversation, and every moment of accountability when no one is watching.

His writing reflects a leader who thinks as much about the conditions that enable people to perform as he does about the performance metrics themselves. He writes about small wins and their outsized effect on leadership presence. He writes about the danger of carrying old resentments into current relationships. He writes about balance not as a soft concept but as a sustainable strategy, because humans, as he observes, are not designed for extremes.

Marc’s attention is firmly fixed on what comes next. He continues to drive strategic growth across the energy sector while deepening the organisational capabilities that allow PTS to serve clients in increasingly complex environments. His work with SAVI is expanding as he brings more of his operational and leadership experience to bear on the challenge of translating military excellence into civilian impact.

At a broader level, Marc is increasingly focused on the question of legacy in the most practical sense. What does it mean to build organisations and cultures that outlast any individual leader? How do you transfer standards, not just skills? How do you ensure that the next generation of operational leaders inherits something worth building on? These are the questions that shape his current work.

“Show up prepared. Do the work right. Leave people better than you find them.”

For a man whose career began behind a dish station and at sea, those words are not a motivational slogan. They are a faithful description of how he has lived every chapter of it.
