Amegy Bank opens first Frisco loan office amid Collin County growth
Amegy Bank opened its first Frisco loan office as Collin County added 42,966 residents in a year, signaling a bigger push for business and property lending.

Amegy Bank has opened its first loan production office in Frisco, placing a new lending foothold at Hall Office Park as it targets $5 billion in local assets across North Texas.
The office is at 2601 Network Blvd., Suite 210, and spans about 6,500 square feet. Carlos Munguia, who leads Amegy Bank’s Dallas-Fort Worth region, said the bank now has $2.25 billion in funded loans, $3.5 billion in total loan commitments and $1.25 billion in deposits in DFW. Munguia was promoted in April 2024 to president and CEO of Amegy Bank-Dallas-Fort Worth, after being identified by the bank in 2017 as its Dallas market president.

The Frisco opening puts Amegy deeper into a market shaped by fast household formation, commercial construction and a crowded fight for deposits and borrowers. Amegy said the office expands its presence in one of North Texas’ fastest-growing regions, and the bank’s own messaging says the new location strengthens its ability to serve businesses and individuals across Collin County and the broader region. For developers, contractors and small businesses, a local loan office can make it easier to pursue financing without relying entirely on downtown Dallas or other out-of-county decision makers.
The timing lines up with the scale of growth in Collin County. The county added 42,966 residents from July 2024 to July 2025, making it the second fastest-growing county in the nation, and estimates cited in local reporting put the population at nearly 1.3 million. That kind of growth feeds demand for office space, retail centers, industrial buildings and housing, while also expanding the pool of affluent households that banks want to reach with deposit, mortgage and commercial services.
Frisco’s transportation buildout adds to the appeal. The Dallas North Tollway is being widened through Frisco between SH 121 and US 380 to handle population growth, a project that should improve access to the city’s major business districts and development corridors. For Amegy, a bigger lending presence near those projects positions the bank to compete more directly for the financing tied to new construction, business expansion and the households moving into Collin County.
