Besides being licensed in the States of Texas and North Dakota, William is licensed in the United States District Courts for the Northern District of Texas and the Eastern District of Texas.

William thoroughly enjoys the game of golf and all aspects of the sport, and works every year on the 14th hole at Augusta National during the Masters Tournament, One of the benefits he receives from Augusta National is a round of golf every year at Augusta in late May.

William is a proud member of the of the Abenaki Nation of Missisquoi in Swanton, Vermont, through his grandmother Nellie Bourgeois Lamphere, who was born in Québec. The tribal language is Algonquin, and William travels frequently to Vermont to work with tribal members in an effort to improve the economic circumstances of the Abenaki. Most recently, he met with tribal leaders of the St. Regis Mohawks in New York State to collaborate on the possibility of gaming enterprises in Vermont. In October of 2016, William was elected to a four-year term on Tribal Council. He is currently representing the tribe as a councilmember in regards to the Vermont Public Service Board review of the sale and decommissioning of the Vermont Yankee nuclear power plant. Active in Native American matters, he worked to resolve the Dakota Access protest, and traveled throughout the Standing Rock reservation to meet with tribal leadership, organizations, and members. He is licensed in North Dakota as well as Texas, and in the summer of 2016, he became an adopted member of the Spirit Lake Sioux Nation in North Dakota, and was given the Sioux name of Tasunka Masa, which translates as Iron Horse. He is a proud graduate of the University of North Dakota and a Fighting Sioux forever.

William is proud of his North Dakota roots. Although he was born in South Carolina, and raised in Atlanta by a mother who grew up in Vermont and a father that grew up in Augusta, Georgia, he graduated from the University of North Dakota and became a part of the Fighting Sioux family. The name was formally given to the University of North Dakota by both the Standing Rock and Spirit Lake Sioux tribes in a Chanupa (sacred pipe) ceremony performed on the campus in 1969, and had been in use at UND since 1932. When the NCAA threatened UND with sanctions because of the “hostile and abusive” nature of the name, William was hired by Sioux tribal members and a state representative to lead the fight to stop UND from changing the name. Unfortunately, political correctness for now has prevailed and UND is now known as the “Fighting Hawks”.

There is also another reason for William’s fondness for North Dakota. William worked as a brakeman and conductor for the Burlington Northern Railroad in North Dakota, and also worked as a “Boomer” railroader working freight trains all across the Midwest, including Montana, South Dakota, Wyoming, Nebraska and Minnesota. As a Boomer, he lived out of his 1976 Chevrolet van, parking it at various terminals in the Burlington Northern system. He still has that van today, now with over 1 million miles on the odometer, and it has been feted by General Motors and even featured in the Wall Street Journal.

After several years as a brakeman/conductor, William was promoted to trainmaster and transferred to the Colorado & Southern Railway in Denver. There, while conducting investigations as part of his responsibilities, William developed a taste for the law which ultimately led to his law degree. Once he started practicing law in Texas, he began telling railroad stories in the courtroom which led to the publication of his book Burlington Northern Adventures: Railroading in the Days of the Caboose published in 2004 by South Platte Press, it continues to sell all over the world.

Ms. Brotherton has a special knack for drafting dispositive motions that win. She does this by researching and knowing the law, understanding the evidence in each case, linking it with the right case law, and then writing her motion in clear concise language that a judge can understand and follow. Ms. Brotherton recently filed a dispositive motion in a very complicated easement case. The firm represents the defendants, who have been using a private road across the plaintiffs’ land for over five years. The same road had been in use for many decades prior to that. The plaintiffs filed suit over three years ago and much discovery has ensued. Ms. Brotherton marshaled the evidence, including antique maps that showed the driveway as part of an old farmstead, and pertinent deposition testimony, and drafted a motion for summary judgment on the counterclaim of easement by estoppel. She also drafted objections and a response to the plaintiffs’ motion for summary judgment on all claims. In March of 2012, the court agreed with Ms. Brotherton and granted the motion for summary judgment on the easement by estoppel claim. The court further denied in full the plaintiffs’ motion for summary judgment.
