About Glesby Marks
The Best in Fleet Management Solutions from Glesby Marks
For nearly five decades, Glesby Marks has helped businesses operate safer, more efficient, and more reliable fleets. Founded in 1976 as an independent fleet leasing company, we built our reputation on long-term relationships, transparent guidance, and a commitment to doing what is right for the customer. Those core values continue to define who we are today.
Our story began when Morris Glesby, Gerald Rauch, and Jay Marks, experienced entrepreneurs with backgrounds in the oilfield supply, energy, real estate, and automotive industries, recognized a growing need for flexible fleet financing that traditional banks were not meeting. After successfully launching and selling a previous fleet leasing venture, they formed Glesby Marks to support the rapidly expanding oil and gas markets in Texas and Louisiana.
As customer needs changed, we adapted. Glesby Marks expanded into a full-service fleet management company, offering maintenance, fuel, and remarketing programs to clients across the country. Our founding leaders played a key role in the development of the American Automotive Leasing Association, helping establish the foundation of the modern fleet management industry.
A Legacy of Integrity and Partnership
From the beginning, our company was built on three principles that remain unchanged.
- Do right by the customer
- Be honest in every interaction
- Build relationships, not transactions
These values shaped our culture and continue to guide every decision we make. Today, the company is led by second and third generation leadership, with the Chairman representing the second generation and the CEO the third. Their stewardship ensures we continue to build on the legacy created by our founders while preparing for future growth.
National Reach. Relationship Driven Approach.
Over the last 50 years, Glesby Marks has expanded beyond our Texas roots into Colorado and Washington state, with vehicles now operating in the majority of United States regions. Our growth reflects the trust our clients place in us and our ability to support fleets across a wide range of industries, including construction, HVAC, electrical, plumbing, logistics, healthcare transport, and food and beverage distribution.
While our reach continues to grow, our approach remains personal. We work with mid market companies that rely on their fleets to deliver essential services. These organizations often lack the bandwidth or internal expertise to manage complex fleet operations. We provide the structure, insight, and professional management they need to operate with confidence and focus on growth.
What We Deliver
As an independent provider, Glesby Marks works with any make or model and designs flexible, transparent lease and fleet management programs that align with each client’s financial goals and operational needs. Our services span the full lifecycle of every vehicle, including:
- Vehicle acquisition and specification
- Upfitting coordination
- Nationwide maintenance support
- Fuel and telematics programs
- License and title management
- Replacement strategy and remarketing
Everything we do is designed to reduce total cost of ownership, improve fleet performance, and protect valuable working capital. This reinforces our role as a long-term strategic partner.
Committed to Who We Are While Growing Into What Is Next
As we continue to expand nationally, we remain grounded in the principles that set us apart. We are not a transactional provider. We build lasting relationships, support our clients long-term success, and stand behind every vehicle and every program we deliver.
Glesby Marks was built on trust, responsibility, and partnership. Today, those same values drive our commitment to helping businesses operate stronger, safer, and more efficiently, now and for generations to come.
