A dedicated criminal defense attorney who will fight for you every step of the way.

Criminal Defense

Make no mistake, if you are charged with a serious crime you need someone who will fight for you. Whether you did it or not, you have an enormous arsenal of rights that you can bring to bear when some lawyer employed by a district attorney’s office or a U.S. Attorney’s office claims you committed a crime.

White Collar Crime

Defending a white-collar crime to a jury is a difficult proposition: your “peers” in the jury box will consist of at least a few who have never worked in a corporation, have never dealt with large sums of money, and are uninformed about the technical aspects of the allegations. They will resent a well-heeled, well-educated defendant who is even accused of wrong-doing.

Civil Rights

People in positions of great trust violate that trust daily. Mothers murder their own children. Congressmen commit sexual improprieties. Doctors commit malpractice. Priests sexually abuse children. Teachers have sexually inappropriate relations with their students. Law enforcement officers are no different – and The Haslam Law Firm can make them accountable to their victims.

Civil Litigation

The Haslam Law Firm handles personal injury claims in Texas and Oklahoma that can include everything from dog bites to trucking accidents.

    “To Whom It May Concern…   About 12 years ago my wife and i were not living our lives as we should by the laws of society and god. I had several felony charges in my past from posecion of stolen vehicle with intent to distribute with posecion of fire arm in commission of a felony, is what i started with first then from there added several more over next 10 years and serving 3 years in prison during this period. So after being home and struggling to adapt back to society and my family i was still not making great choices but trying.   Any way, I’ve got several felonies been paying court cost and fines to court house everyone for 15 years been on probation or parole 12 years. My wife, my self and our children were staying in camper trailer on so called friends property 200 yrds from his house were he was manufacturing meth had firearms the whole deal.   one morning while we were all sleeping several police officers charged the camper all armed and pointing firearms at me my wife and children said they had warrent for my arrest and arrested me my wife and took my children to dhs. Spent 9 months in jail could not afford a lawyer so i was appointed one and we hired my wife a lawyer that was highly recommended knowing i without a doubt am facing 20 to life. And that is what district attorney asking for and to never have any parenting rights to my children ever again.   i forgot to tell you my court appointed lawyers name was DONALD HASLAM THE ONE AND ONLY. He was straight forward, direct, to the point and only wanted facts. Yes and no answers and no B.S. He was just damn mean and rude. But i knew the first 60 seconds he told me what he expected of me and explained to me i was to expect miracles from him because he did not care weather i paid him or the state of Oklahoma. He took his job very serious and he new the law.   Donald Haslam has been been a life long friend for almost 20 yrs. I refer to him as superman and always will. We consider him one of our family and love him dearly.He is a man of all men.   oh yea my friend got all charges dismissed on me and that so called top notch lawyer didn’t do one thing to help so Donald got all her charges dismissed. The police had bad warrent there never was one. ONLY DONALD HASLAM could go against them all and win, by the laws of society.   I currently own my own business. I have made over 100,000.00 yr past 8 yrs. I have two sons that just graduated from college. my oldest has 3 degrees his last degree was criminal justice and is currently working towards being accepted to train for employment for u.s Marshall.   my youngest son now working towards his masters degree to coach college. he turned his life over to god 3 yrs ago and has been ministering to athletes all over the country since being saved.   why i still don’t know but my wonderfully, beautiful wife has kept me around for 27 yrs now and i thank god for her everyday i get to see another day.   I owe all these blessings to Donald, im not deserving of my freedom. Im not deserving of all i have. Donald HASLAM said i was. im so very thankful someone believed in me. He’s mean. He’s to the point. And believe this above all he loves what he does. He knows the law. Its been about 15 yrs, but i can still here him in judges chambers like it was yesterday rasing his voice not excepting anything but dismiss their case. Because that’s the day I started living.”  

    As with all testimonials, I have reprinted Cooper’s letter verbatim here, as he originally wrote it. I feel his sincerity is so well-communicated in this form. – Don Haslam
