Practicing for over 10 years, Andrew Morris is our Associate Litigation Attorney in our Dallas office. Andrew attended Texas A&M University, majoring in Marketing.

He received his JD (Doctor of Jurisprudence) in 2005. His activities and honors include: Dean’s List, Faculty Honor Roll, a member of the Phi Delta Phi International Legal Fraternity, and New Student Mentor. Andrew was then licensed by the State Bar of Texas in late 2005.
“Andrew has been with the Coffey Firm for 9 years. I first met Andrew when as a young lawyer, he sought me out and asked if he could sit on a few jury trials with me for experience. Every trial he sat with me, we ended up winning. I was so impressed with him, that I offered him a job. One of the most impressive traits about Andrew is his work ethic. I have seen him come to work many times extremely ill (insisting on staying, even after I begged him to go home). Andrew is an old school lawyer. He lives by your word being your bond. His father and uncle were both practicing lawyers in Dallas (his father still practices family law). Andrew played high school football and understands the meaning of tough. He once went in on a motion to suppress with an hour’s notice and won. Many lawyers would have refused the opportunity. Andrew is very kind and sensitive, outside his get down to business persona. I particularly love the fact that he remembers everybody’s name and their particulars. It is not unusual at all for me to receive a text from Andrew after hours telling me he just ran into one of our clients out and about. Andrew is a very social guy, who lives, breathes, and loves his hometown of Dallas. Thank you Andrew, for all you do. You have my greatest respect.”
Lanny Begley | Associate Attorney
(Tarrant, Parker, and Johnson Counties)
•Initial client consultation
•Case law research
•Motion hearing management
•Pre-trial and other applicable motions
•Periodic trial case review
Lanny attended Austin Peay State University in Tennessee for his undergrad, where he was involved in Kappa Sigma Fraternity and the Honors Program. In 2008 Lanny received a BA in Political Science and a minor in English Language and Literature. From there he went to Baylor University School of Law, and was active in Phi Alpha Delta, and the Order of Barristers. There, he received his J.D. in 2011, and sworn in to practice law in Texas in 2012. Mr. Begley has worked in both civil and administrative law before starting to work at the Coffey Firm. When not working, he and his wife try to fill time with travel and live music.
Lanny has also suffered the stressful process of a DWI arrest. He knows what our clients have gone through, and wants to lessen the confusion and fear of the court system. Fighting for our clients is of the utmost importance to Lanny, especially after experiencing it all from their perspective.
“When I first met Lanny in his interview, I was struck with his forthrightness. He reminded me a bit of myself. He is a very serious scholar. I am so grateful to have Lanny at the firm and enjoy mentoring him. He has masterful control of his temperament and exudes professionalism in any and every setting. Lanny initially worked in our Dallas location. This was a great experience for him as Dallas County is far larger, and many things are done differently there. Lanny has quickly earned the respected position of arguing motions and handling appeals, in addition to daily court docket settings. Recently, he was published in the Voice of the Defense (statewide) critically analyzing a Court of Criminal Appeals decision which is frequently used out of context in DWI motions to suppress. Lanny has served on the board of the Arlington Young Lawyers Association for the past several years. He enjoys giving back to local community needs through the volunteer work of this group. His dedication to helping others charitably represents the kind of noble character we value at the Coffey Firm. When asked to describe how he felt about helping others at the Coffey Firm, he responded “The presumption of innocence is one of the most important rights people have in our country, and I am happy to work every day to make sure our clients are afforded it.” Thank you Lanny for all you do for the Coffey Firm and our community. It is privilege to have you on our team.”

Rex Barnett is currently licensed in all Texas state courts, in the United States District Court for the Northern District of Texas, and the United States District Court for the Western District of Pennsylvania.
“Ran into one of my favorite colleagues last week, who was an excellent and well respected former district attorney. We discussed how Rex had joined my law firm. My colleague commented, “I love Rex!” Rex is one of those attorneys that is ‘what you see is what you get.’ He pulls no punches. He plays no games. He fits perfectly into how we at the Coffey Firm, pride ourselves on ethics, diplomacy, as well as skill. He was board certified in criminal law from 1999 to 2010 (when he moved to Pennsylvania). Rex was a former Travis County and Tarrant County District Attorney in the appellate divisions. Rex has tried many felony cases including child molestation charges and capital murder (where his clients faced the death penalty). Nothing scares Rex. He is always up to any and all challenges. Rex is a hometown guy. He graduated from Paschal High School before graduating from Austin College in Sherman and then the University of Texas at Austin Law School. Rex has practiced longer than me (28 years)! Rex and I have smoked many cigars over hundreds of hours during courthouse lunch breaks at Tobacco Lane (now closed). I certainly appreciate all the mentoring he provided me in my early years, as I very much enjoy and cherish his friendship. It is an honor to work alongside him today. Rex comments “Criminal defense is my first love, it’s the only type of law that really interests me.””
