“We have been graciously provided an opportunity to succeed because of the leadership and community service of many who came before us,” Brett says. “For me it is not an option to serve my community, it is an obligation. It is my desire to leave this place better than I found it, to position all future generations to have an opportunity to succeed. That is really all any of us should hope for, the opportunity to prosper.”

Nell Graham

Nell Graham grew up in Dallas, Texas and graduated from Woodrow Wilson High School. Nell worked at Texas Instruments as secretary to the Manager of General Accounting when she met Jim Graham who was branch manager for International Harvester in Dallas. Jim and Nell married in 1965 and opened Graham International in Sherman, Texas in 1965. Nell has two sons, Jim T. from Nashville, Tennessee and Brett Graham of Denison, Texas. After opening the dealership, Nell worked in all aspects of the business through the years. In the 1970’s they acquired some of the first llama to Texas, and the Graham Llama Ranch was established. Jim and Nell enjoyed a thriving operation, showing, breeding and selling llamas all over the Southwest US. Over the years the family farm had a variety of exotics including antelope, zebras, buffalo, donkeys, goats, deer and llamas making the typical day anything but. She successfully navigated the company after Jim passed away in 1993, bringing Brett into the business shortly thereafter. While still active in the business, she spends much of her time with her grandchildren and at her second home in Puerto Aventuras, Mexico.
