American National Bank of Texas Bankers Have Built Relationships With Collin County Businesses That Span Decades
Casey Stewart has witnessed Collin County’s evolution through the changing businesses he serves. When Stewart entered the market in 1998, he focused on agricultural loans in Allen. Today, his clients include manufacturers, technology firms, developers and businesses supporting a much larger local economy. “We used to bank farmers, and we financed their crops in Allen,” Stewart said.
Stewart has adapted alongside the market. He joined American National Bank of Texas (ANBTX) 31 years ago as a part-time teller while completing college, progressed through various roles, built a client base in Allen and later assumed leadership positions in Plano. In 2016, he became regional market president for Collin County.
The market has changed significantly as well. Collin County’s population has grown nearly 22% since 2020, reaching almost 1.3 million residents in 2025. Last year alone, the county added nearly 43,000 people, the second-largest increase among all U.S. counties.
ANBTX has grown alongside the county. ANBTX operates four banking centers in Collin County, along with a commercial loan production office in Frisco. This growth is evident in the numbers. ANBTX’s Collin County operations hold approximately $1 billion in deposits and $700 million in outstanding loans. In 2025, the team generated nearly $200 million in new loans.
Much of the bank’s success is due to the team Stewart leads. Key team members include Amber Dawson, commercial lender in McKinney; Jason Dudley, Frisco market president; Rick Lewis, senior market lender in McKinney; Hunter Lord, McKinney banking center president; Kameron Mayfield, community lender in Plano; Brett Perry, Plano banking center president; and Charles Thomas, community banker in Wylie.
Perry has been with ANBTX for 13 years, Lewis for over 20 years, and Dawson is nearing a similar tenure. Dudley, though new to the team, brings decades of experience with owner-operated businesses in Collin County.
This range of experience is valuable. Some bankers have built relationships with Collin County businesses over decades, while others are developing new connections. Stewart saw Perry grow from a young banker to a market leader, and now Perry mentors the next generation.
“Our focus is relationships,” Stewart said. “Our quest is to get out and see people constantly.”
Many customers have experienced similar growth. Stewart recalls financing an entrepreneur’s first truck and trailer. Over time, that business grew into a major underground utility contractor serving Collin County and Dallas.
Another long-term client is Krypton Solutions. Stewart began working with the company early on and has supported it for nearly two decades. Today, Krypton Solutions continues to grow and is planning another expansion.
Perry has watched his own clients grow over the years. One entrepreneur first came to him for help with cash flow and a small line of credit. Since then, the business has grown well beyond where it started. “I’ve had the opportunity to grow up in this bank alongside a lot of our customers,” Perry said.
“You might start with someone when their business is small and they need that first line of credit, and then you get to watch what they build over the next five, 10 or 15 years. I learned how important those relationships are from Casey and the bankers who invested in me early in my career. Now I get to do the same thing with the younger bankers on our team.”
These relationships have developed in tandem with Collin County’s transformation. ANBTX played an early role, financing infrastructure near U.S. 75 and Bethany Drive in Allen years before the area became a major business and employment center. Long tenure is important amid widespread industry consolidation. Banks change ownership, names and staff, often requiring business owners to start over with someone unfamiliar with their company’s history.
ANBTX has remained independent since its founding in 1875. In Collin County, many bankers have stayed long enough to understand both where their customers are today and where they began.
For nearly three decades, Stewart has witnessed young bankers become market leaders and small businesses grow into established companies. Today, those he mentored are now guiding the next generation. Collin County has changed significantly since Stewart arrived in 1998, but his approach remains consistent: know the customer, understand the business and support its growth.
For Stewart, the next chapter is watching a new generation of ANBTX bankers build relationships and careers that endure just as long.
