Judith Zadravec – July Employee Spotlight

With more than three decades in the packaged gas industry, Judith Zadravec has seen her fair share of change, but she’s never shied away from it. Judith joined MATHESON 21 years ago, beginning her journey in the FTIR Lab in Twinsburg, OH. Drawn by the company’s strong reputation for lab quality, she quickly found alignment with its values and a clear path for long-term growth. Today, she serves as the Lab Manager at the Twinsburg location, where her expertise continues to shape and strengthen the work being done.

If you’re not riding the wave of change… you’ll find yourself beneath it.

Judith

Judith’s role is central to the day-to-day operations of the lab, especially in specialized areas such as EPA Protocol Gases, as well as medical and food and beverage gases. One of the most defining moments of her time in Twinsburg came in 2012 with the addition of industrial filling to the site’s capabilities. A change that introduced new complexities and required the team to integrate industrial and specialty gas systems under one roof. Navigating this hybrid model has been one of the most challenging aspects of her career, but Judith has approached it with the same adaptability and focus that have carried her through every chapter of her professional journey.

2017 was a banner year for Judith and her team when they earned ISO 17025 accreditation for the Twinsburg Lab’s EPA Protocols, a major milestone that underscored their dedication to quality, precision, and regulatory compliance. Achieving this accreditation required focus, teamwork, and a deep understanding of the standards that guide lab excellence. But Judith’s efforts didn’t stop there. She continues to play a key role in upholding that standard through close collaboration with MATHESON’s only other ISO 17025-accredited site: the EPA Lab in New Johnsonville, TN. Together, the two labs maintain a consistent, forward-looking program that evolves with the demands of the industry.

What makes MATHESON stand out to Judith goes far beyond technical excellence. She’s especially drawn to the strong safety culture, particularly the Right of Refusal policy, which empowers employees to speak up if something doesn’t feel safe. That commitment to doing things the right way, with both safety and quality at the forefront, has kept her motivated and aligned with MATHESON’s values. She encourages new employees to never hesitate in asking questions, believing it’s far better to seek clarity than risk getting something wrong. She believes that fostering a culture of openness is essential to growth and success. 

Displayed in her office is a quote that reads, “If you’re not riding the wave of change… you’ll find yourself beneath it.” It’s more than a motto; it’s a reflection of how Judith approaches her work each day, with calm consistency and a drive to lead by example. Her ability to adapt, support others, and uphold high standards continues to elevate the work of her team and the broader organization.

Nathan Carl – June Employee Spotlight Video

In the dynamic world of sales, few individuals embody the spirit of determination and connection quite like Nathan “Nate” Carl. When he first joined Continental Carbonic Products, a MATHESON company, in 2014, Nate was looking for more than just a job – he was seeking an industry he could connect with. With over a decade of sales experience, including a background in communications, he found something special in Continental’s mission and culture. What began as a leap into unfamiliar territory became a fulfilling journey, culminating in his recent promotion to Continental Carbonic’s Regional Sales Manager for the East.

The fact that the company would rather you not do something if it is potentially dangerous than put yourself in harm’s way is a testament to how we care about our employees.

Nate

Nate’s sales style is characterized by curiosity and a consultative approach, taking the time to understand the unique processes of different industries and how they use dry ice. He thrives on solving problems, building strong relationships, and helping customers improve their operations. His days are filled with everything from prospecting and managing accounts to mentoring newer sales reps and collaborating with branch managers. The diversity in his work keeps each day fresh and rewarding, allowing him to grow alongside the company he proudly represents.

One of Nate’s proudest moments came in 2020 when he was named Salesperson of the Year. “Continental has many tremendous sales reps, and it is a difficult award to win,” he says. For Nate, that award went beyond personal success; it reaffirmed his belief in the power of steady progress and the motivation to continue pushing forward.

Nate appreciates the company’s Right of Refusal policy, which encompasses a genuine concern for employee well-being, noting, “The fact that the company would rather you not do something if it is potentially dangerous than put yourself in harm’s way is a testament to how we care about our employees.”

Outside of work, Nate embraces life with the same energy and enthusiasm he brings to his role. Whether traveling with family, boating with friends, skiing in winter, or golfing in the summer, he values experiencing new things and enjoying the moment.

For Nate, the heart of his job lies in the people. He values the camaraderie, support, and shared drive within the sales team, where collaboration is as important as competition. His advice to others is simple yet impactful: treat people well, stay committed to the process, and believe in what you do. That mindset has carried him far, and it’s clear he’s just getting started in this exciting new chapter.

Julyann Tu – June Employee Spotlight

A proud member of MATHESON’s Air Separation Unit (ASU) commissioning team, Julyann Tu blends her technical expertise with her passion for continuous learning. With over a decade of experience in application engineering and technical training, Julyann holds a degree in industrial engineering and an MBA in technology leadership. In 2020, she led a training session with the Cayce ASU team, introducing her to the fast-paced, detail-driven nature of their work. Julyann welcomed new challenges and opportunities as she joined the MATHESON team in 2021.

If you keep your head down and put in good work, good things will come your way.

Julyann

As a Control Systems Engineer, Julyann plays a critical role in bringing MATHESON’s ASUs online safely and efficiently. Her work goes far beyond understanding control logic; it demands a deep knowledge of how every instrument, valve, and system within the plant works together. Working closely with teammates ensures each adjustment supports the plant as a whole, making the process both precise and rewarding. It’s a shared responsibility where collaboration is a key component of the job. The wide variety of projects keeps things dynamic, opening the door for continued learning and growth.

One project, however, stands out among the rest. Julyann traveled to MATHESON’s HyCO plant in Talara, Peru, to help resolve a challenging automation issue. It was a professional milestone and a cultural adventure wrapped in one. Beyond the technical work, she found herself immersed in a unique environment filled with some of the best seafood she’d ever eaten. The trip not only expanded her expertise but also gave her unforgettable stories to bring back to the team.

Outside of work, Julyann can be found digging through antique malls and estate sales for unique vintage furniture and home décor. She balances her active lifestyle of hiking, cycling, and working out with a love of baking, something she picked up during the pandemic and now shares with family and friends. Her mantra? A humorous quote from Lil Wayne: “Real G’s move in silence like lasagna,” a reminder that “if you keep your head down and put in good work, good things will come your way.”

Julyann’s passion for staying on the forefront of control systems technology helps ensure MATHESON stays up to date in the latest versions of software, hardware, and control philosophies. She values the company’s commitment to safety, opportunities for hands-on learning outside of her primary skill set, and the strong sense of teamwork that’s carried her through some of the most complex projects. With curiosity, creativity, and just the right amount of humor, Julyann brings energy and expertise to every site she visits.

Brian Spraker – May Employee Spotlight

Brian Spraker has been a valued member of the MATHESON team for over 13 years, currently working as an IT Support Specialist. His technology-focused career began in middle school while working at a small-town electronics store, where he built his first computer. Brian enhanced his customer service skills in various call centers before transitioning into IT. He later joined Continental Carbonic Products, which subsequently became part of MATHESON. 

Those early experiences taught him how to listen, adapt, and provide support, skills that remain central to his work. Brian has grown into a “jack-of-all-trades” in IT. His responsibilities range from helpdesk support and troubleshooting to phone system upgrades and mobile device management.

Everything seems difficult until you learn how—and then it feels like second nature.

Brian

One of Brian’s most challenging and rewarding projects came during the height of the COVID-19 pandemic when he was tasked with migrating Continental Carbonic employees to the MATHESON mail server. The effort required long hours, careful coordination, and seamless execution. At the core of Brian’s work is a passion for problem-solving and helping others. He enjoys collaborating with teammates across the organization and values the friendships and connections he’s built along the way.  

Recently, he led a major cost-saving initiative that cut the company’s phone service expenses by $2.4 million, an ongoing effort that continues to make a lasting impact. “As someone who is frugal and finds ways to make a dollar go further in my personal life, I also see that as a focus within the company,” he says. It’s a mindset that aligns closely with MATHESON’s emphasis on financial responsibility and efficiency.

Being a jack-of-all-trades doesn’t stop at closing time; it carries over into his hobbies and interests outside of MATHESON. Brian is actively involved in his local church and enjoys gardening fresh vegetables at home. He also manages rental properties in Florida, including a vacation condo near the beach in Navarre. Brian jokes that he finds it hard to truly “relax” on vacation—if there’s nothing on the schedule, he’ll end up responding to emails and helping teammates instead of enjoying the beach!

For those new to MATHESON or just starting in IT, Brian offers simple, solid advice: don’t be afraid to ask questions. “Everything seems difficult until you learn how—and then it feels like second nature,” he says. His curiosity, persistence, and commitment to supporting others continue to make a meaningful impact at MATHESON—one solved problem at a time.

Bob Gould – April Employee Spotlight

Bob Gould is celebrating 33 years with MATHESON this month, marking a long and accomplished career in the industrial gas business. Bob has taken on many roles since joining in 1993, including driver trainer, credit representative, and technical support before landing in his current position as an Inside Sales Representative (ISR). His strong work ethic and willingness to embrace new challenges have made him a valuable resource for customers and colleagues.

In his role as an ISR, Bob prioritizes exceptional customer service, ensuring each customer finds the right solution for their needs. Whether answering technical questions, placing orders, or resolving vendor issues, he approaches problem-solving thoughtfully and carefully. He believes in guiding customers toward better solutions without making them feel wrong – a principle he learned early in his career. Bob jokes, “If the customer is asking for 1109 welding rod, turn the number over, it is most likely 6011!” Beyond sales, he assists with various tasks like stocking inventory or receiving freight. 

Live each day for what it is. Tomorrow is another new day.

Bob

Bob’s dedication to keeping operations running smoothly has been evident in both times of crisis and times of growth. When a fire destroyed MATHESON’s South Portland filling facility 25 years ago, he was critical in maintaining gas supply by transporting cylinders between locations, often working long overnight shifts to ensure customers were unaffected. Years later, during the 2018 relocation of the Lewiston branch, his technical expertise proved just as essential. He worked closely with the IT department to set up computers, phones, and internal communications, ensuring a seamless transition. 

Outside of work, Bob is a self-proclaimed “geek”. He is passionate about computers and amateur radio, using his skills to support emergency communications. He volunteers with organizations like the Oxford County Emergency Management Agency and the Maine Lung Association’s Trek Across Maine, ensuring reliable radio communications for large-scale events. These passions unexpectedly gave him the tools to excel professionally. “What I really was not aware of at the time was that a geek really fits into this business well. There is a lot of technology in the welding process, and it is always changing.”

Bob’s advice for new employees is simple: always strive to give 100% and take advantage of every learning opportunity. He believes that training and continuous learning make the job easier and more enjoyable. His mantra, “Live each day for what it is. Tomorrow is another new day,” speaks to his positive outlook and adaptability—qualities that define his long and successful career at MATHESON.
