Tackling Logistics Challenges Together

Chief Financial Officer

Mark Muenks serves as Materialogic’s CFO and sits on the executive board. Mark provides strategic financial oversight, managing all aspects of the company’s planning and budgeting process, financial reporting, interpreting and analyzing information regarding financial performance, and providing important insight into the setting of future business goals. Mark advises the Leadership Team and strives to contribute to the special spirit of camaraderie that exists at Materialogic. Mark’s curious and intuitive personality enhances his ability to provide guidance on the best ways to financially support the company’s success.

Mark has served as CFO at Materialogic for over twenty-five years, but his roots go even deeper. As a child, he often spent Saturday mornings with his dear aunt Ellen Darling at Materialogic’s offices, exploring the building, making hot chocolate in the breakroom, and using the copy machine for “creative” photocopies. After Mark finished his degree and was working in management, it was Ms. Darling who invited Mark to join the company, and he’s been in his current role ever since. Mark says, “I believe it is important to provide an excellent level of service, whether I am serving a client or supporting a fellow employee. I believe that good relationships are vital in business.”

Mark lives in St. Louis with his wife, three sons and daughter. In addition to family time, Mark loves golfing, taking care of his home, and working on classic cars.

Chief Operating Officer

Carrie Stempin, a member of Materialogic’s executive board, is the company's visionary, imagining the future of business, then setting appropriate goals to ensure the entire company is working in the same direction towards success. Day to day, Carrie oversees the Sales, Client Operations, and Solutions Leadership teams, manages new client contracts, and reviews the operations budget, all with the goal of making sure every team has the resources, training, and staff they need to carry out their mission. Carrie believes in leading by example—being a good communicator, empathetic listener, and fearless decision maker are all crucial qualities she brings to her role. Materialogic’s business model has created the unique position of being a strategic and intimate partner with their clients, which is both a tremendous opportunity and responsibility. Carrie says, “We view ourselves as an extension of our client’s business; therefore, we are passionate about caring as much about their business and customers as they do.” Carrie understands that caring about people is as important as caring about results.

Carrie has over two decades of service at Materialogic on top of another decade in the inventory and fulfillment industry. Her entire career is built on understanding the industry, anticipating and adapting to challenging circumstances, such as the recent pandemic, and improving as a leader every day. Under Carrie’s leadership, none of Materialogic’s clients suffered a fulfilment shutdown during one of the most challenging times in recent U.S. history.

Carrie is a life-long resident of St. Louis, and lives here with her husband, two daughters and beloved Boxers. Relaxing at home with her family, books, music, and friends gathered around is what refreshes her; however, she will never turn down a girls’ night out. Carrie is also an aficionado of St. Louis culture and loves to explore all the music, food, art, sports, and nature that St. Louis has to offer.

In her role, Jennifer leads all sales and marketing initiatives, overseeing business development, client acquisition, strategic partnerships, brand management, marketing strategy, and revenue growth. She works closely with clients and prospects to develop customized supply chain and fulfillment solutions while helping shape the company's long-term strategic direction.

Jennifer's commitment to Materialogic's core values—Partnership, Dedication, Action, and Optimism—has been a driving force throughout her career. She is passionate about building meaningful relationships, fostering collaboration, and creating exceptional client experiences.

Vice President of Client Success

As Materialogic's VP of Client Success, Teresa's focus is building and sustaining strong business partnerships. She oversees the full lifecycle of each partner account — from onboarding through delivery and beyond — ensuring every relationship is healthy, well-supported, and set up for the best possible outcomes. Teresa leads the Client Service Group and works closely with internal departments and external vendors to shape a seamless partner experience. She understands that excellence in partnership development isn't just good service — it's central to Materialogic's ability to compete and grow.
Teresa brings more than 25 years of 3PL industry experience to her role, including six years as a 3PL customer herself. That time on the other side of the table gave her a firsthand understanding of what businesses actually need from a logistics partner — insight she draws on every day. She is currently in her second chapter at Materialogic, having previously spent 13 years in Account Management and with sister company Infoplus before returning in her current role. Teresa holds a degree in Business Management, and regards her years of hard-won experience — the lessons, the missteps, and the wins — as the real foundation of her professional approach.
Outside of work, Teresa's greatest pride is her son Aidan. A long-time St. Louis resident, she loves time with friends and family, especially at the pool or beach — and is rarely in the car without an audiobook on and two or three more already queued up.

Operations Manager

Jacob Muenks oversees all warehouse operations and building maintenance, ensuring every department has what it needs to run smoothly and efficiently. Jacob leads from the front, believing that he'll never ask someone to do something he hasn't done himself. That hands-on philosophy shapes every decision he makes. As Jacob puts it, "When faced with a decision, often times the right thing to do is the harder choice, but more rewarding in the end." For Jacob, earning his team's trust starts with holding himself to the same standard he expects of them.

Jacob has spent five years building his career from the ground up. He started as an order picker, moved into the LTL department, and was later promoted to inbound supervisor, where he led a complete overhaul of the receiving department—building new processes, shaping a strong culture, and getting the team performing at exceptional levels. His impact there made clear he was ready for a bigger challenge, and after nearly two years leading receiving, he was promoted to Operations Manager to bring that same influence to the operation as a whole.

Jacob is a lifelong resident of St. Charles, Missouri, where family comes first. A dedicated competitor at heart, he's always up for a challenge—golf and skiing are his biggest passions, with a little bowling mixed in. If there's a competition happening, Jacob wants in.
