This article dives deep into the legacy of Doyle Sims & Sons Trucking, the key players who built it, and the surprising details of the massive fleet that now operates under the Trimac banner.

The Sims Family Legacy: A Brief Biography of Key Figures

Doyle Sims & Sons Trucking was more than just a company; it was a decades-long family endeavor rooted in Gleason, Tennessee. The company's success is directly attributable to the vision and hard work of the Sims family and the dedicated leadership that followed.
  • Doyle Sims (Founder): The patriarch who established the company in 1949. Sims laid the foundation for a business centered on reliable road transportation and a commitment to customer satisfaction. His initial vision created one of the region's most trusted truckload carriers.
  • David Sims (Son and Former Owner): Following his father's footsteps, David joined the company in 1982. He eventually became the majority owner and played a critical role in expanding the company's operational reach and solidifying its reputation in specialized hauling before the acquisition by Trimac.
  • Johnny Wagster (Key Leader): A pivotal figure in the company’s modern growth, Wagster joined Doyle Sims & Sons in 1998. Under his leadership, the company’s fleet size saw commendable expansion, growing from approximately 64 trucks to over 120 tractors, significantly increasing its capacity and market presence in the two decades leading up to the sale.
This lineage of leadership ensured that the company maintained its core values while adapting to the evolving demands of the freight and dry bulk transport industry.

5 Surprising Facts About the Doyle Sims & Sons Trucking Acquisition

The sale of a long-standing, family-owned business is always a complex event, and the acquisition by Trimac Transportation is no exception. Here are the five most significant details that highlight the company's scale and the impact of this transition.

1. The Acquisition Bolstered Trimac's Specialized Fleet by Over 110 Tractors

The deal was a significant growth injection for Trimac, a major player in bulk transportation. The acquisition immediately added more than 110 tractors and 120 trailers to Trimac's existing fleet. This substantial addition wasn't just about numbers; it included a diverse mix of specialized equipment, notably liquid and pneumatic tankers, which are crucial for hauling chemicals, dry bulk, and lightweight aggregates. This move instantly strengthened Trimac's capacity for complex, non-standard freight.

2. The Company’s Services Were Exceptionally Diverse

While many regional carriers focus on general freight, Doyle Sims & Sons Trucking developed a reputation for handling a wide array of specialized hauls. Their service portfolio was impressively broad, making them a one-stop shop for many industrial clients.

Key areas of specialization included:

  • Bulk commodities like clay, grain/feed, and dry bulk.
  • Specialized liquids and chemicals.
  • Lightweight aggregates and construction-related materials.
  • General freight, paper, and farm supplies.
This operational diversity, primarily servicing the South and Midwest, was a key asset that made the company highly attractive to a large-scale operator like Trimac.

3. The Deal Included a Separate Brokerage Operation

The acquisition was a two-part deal. Beyond the physical assets of the trucking company, Trimac also acquired the associated brokerage operations, known as Sims & Sons. This is a critical detail, as a successful brokerage arm provides flexibility, allows the combined entity to manage overflow freight, and offers a wider range of logistics solutions to customers, extending the operational reach beyond the core fleet’s capacity.

4. The Fleet Size More Than Doubled Under Recent Leadership

The impressive size of the fleet at the time of the sale was the result of consistent, strategic growth under the leadership of Johnny Wagster. When he joined the company in 1998, the fleet comprised around 64 trucks. By the time of the acquisition, this number had grown to over 110 tractors, showcasing a sustained period of expansion and modernization. This growth trajectory underscores the company's operational efficiency and market success in a highly competitive sector.

5. It Was Trimac’s Fourth Acquisition in a Single Year

The purchase of Doyle Sims & Sons Trucking was part of a broader, aggressive growth strategy by Trimac Transportation. Reports indicate this was the fourth acquisition made by the Canadian transportation giant in that year alone. This pattern of strategic acquisitions highlights the rapid consolidation occurring in the North American bulk hauling and specialized trucking market, where larger companies are absorbing established regional carriers to gain market share, specialized expertise, and geographical advantages in key areas like Gleason, TN, and the broader South and Midwest.

The Future of Specialized Hauling Under Trimac

The integration of Doyle Sims & Sons Trucking, Inc. into the Trimac portfolio marks a new chapter for the 75-year-old carrier. While the family ownership has concluded, the operational excellence and specialized capabilities built over decades are now part of a larger, international network. The 95 employees who were part of the Doyle Sims team are now contributing their expertise to a significantly larger entity. This transition is expected to provide former Doyle Sims customers with access to a broader range of services and a larger fleet, enhancing the overall reliability and reach of the specialized transport services they rely on. The focus on hauling key commodities like dry bulk, chemicals, and aggregates means the Gleason, TN operation will likely remain a crucial hub for servicing the industrial heartland of the South and Midwest. The legacy of dependability, established by Doyle Sims in 1949, continues, albeit under a new, larger corporate structure.
