Null comes to J&M Tank Lines with 30 years of experience within the trucking industry in
segments such as Dry Van, LTL, Dry Bulk and Liquid Bulk. He has overseen day-to-day
operations and managed dozens of terminals with revenue achievements spanning hundreds of
millions during his time.
Null has a focus on customer relations and professional development for his team to ensure
growth opportunities are not just met, but also offer a smooth expansion experience for all
parties. His experience with setting and managing company policy provides him with a wellrounded perspective within trucking, ranging from areas such as finance, maintenance and safety
to human resources, recruiting and sales.
“Any time a new leader is introduced into an organization it allows for changes in business
opportunities and growth strategies,” says Peter Sumerford, J&M’s President and Director of
Sales. “Harold and I have invested a great amount of consideration into the future of J&M and
the qualities we expect from our fellow officers. We are confident Jeff will be a strong addition
to J&M Tank Lines and our people.”
Null is an East Texas native and Marine who believes trucking is a people business. For him it is
not about how many trucks a company has, but the impact individuals make, allowing for
relationships to flourish and standards to be exceeded.
“I am very excited to join the J&M team,” said Null. “The Sumerfords have set a standard, and I
look forward to working with everyone while continuing to move things forward.”
The thrill of accomplishment and conquering a challenge is what has attracted and kept Null in
the trucking industry. The ability to set goals and accomplish those goals in an ever-changing
environment is a highlight that falls second only to Null’s passion for people and their
development.
“Trust is a big part of my leadership style,” said Null. “I ask a lot of questions and like to
understand the current operations, what is working and what areas can we improve.”
“We have made strong additions to our leadership team in the last several years,” says Harold
Sumerford, Jr. J&M’s CEO. “I believe Jeff will help us further the leadership initiatives we have set to support our business strategy and will serve as a key stakeholder in the professional
development of our employees.”
