He taught SAT prep and traded financial futures on the floors of the Chicago Board of Trade and the Chicago Mercantile Exchange to finance his undergraduate education. He joined several large banks as a bond, currency and derivatives trader, including NationsBank Texas, where he also managed a bond portfolio in excess of $50 million. He put himself through the University of Tulsa Law School while Vice President and foreign exchange trader at Liberty Bank & Trust in Tulsa, a $2 billion bank ultimately acquired by Bank of America.

He has served as Chancellor for the Diocese of the Southwestern States [the Anglican Church] and board member of Domestic Abuse Helpline for Men and Women, a national organization that assists people in abusive relationships and rejects the myth that these relationships more often afflict women than men.

Haslam is admitted to practice in the Eastern, Western, Southern and Northern District Federal Courts in Texas, the Eastern, Western and Northern District Federal Courts in Oklahoma [there is no Southern District in Oklahoma] as well as the Oklahoma and Texas state court systems.

Amazing go to lawyer.
Mr. Haslem was exactly what I needed. He did such a good job I rehired him again and he won all of my cases and even won me money. He will go to the end of the world for his clients and he shows every bit of compassion to his clients. I definitely was out into a horrible place with my divorce and criminal cases and he conquered all for me. He proved my innocence and even proved the perjury to the other part of the suits. He will always be my go to lawyer if I need one.

What a great lawyer!
Donald Haslam was a blessing to my entire family during several months of back to back court hearings in a family law case involving my son. He was by far the most organized and communicative lawyer I’ve ever met. He made sure we stayed on top of everything ultimately winning custody of my son.

He got my felony Crim_Misc_Imp_Pub_Svc<30K droppeddown to a class C misdemeanor Disorderly Conduct. I got 3 months deferred probation no reporting and pay $200.00 restitution. Mr.Haslam is really good he will get all evidence that there is to get,that means even if you have police body cams he makes sure he got everything.

Don Haslam attacks your case like it's life and death. He follows through every step of the way. I never worried whether he was working on my case. He kept me informed all the way. He even followed up after the case was closed to make sure everything was going as expected. Bottom line, he won my case and if you want to win, Don Haslam is your man.

Torres Review
You are never prepared to be in a law suit situation where your character is at stake. Having Mr. Haslam on my side was a God-send. His professionalism and gentle spirit were extremely comforting and reassuring during this extremely stressful time. He was knowledgeable and in control of the facts and I believe he represented me well. As Mr. Haslam worked to prepare family and friends who would testify in my behalf, they too had nothing but positive comments about him. I would recommend Mr. Haslam highly for his integrity and professionalism.

I was facing a MTR on a state jail felony case as well as new Class A & Class B misdemeanor charges. Mr. Haslam was able to negotiate with the DA and reach a deal that did not include any jail time. The outcome was far better than I thought possible. I highly recommend Mr. Haslam.

Compassionate Attorney
We met one with money in hand, Money in which he refused to accept before meeting and interviewing our children it wasn't until he was completely satisfied that they were okay he then accepted the money and our case against Child Protective Services. We had only two days prior to the central so he had to work abruptly. He was well-prepared when we arrived at court. He was able to prove not only where we innocent of what we were accused butt that the CPS caseworker lied under under oath. Following the trial my son had brain surgery, Don checked on him frequently, and expressed his concern often. he is very compassionate and much more than just an attorney, that's awesome at his job, but a caring loving human being who helped us keep our family together he will stay in our hearts forever. Your friends Christy and Jody

Don Haslam Attorney
Don was one of the best lawyers I have ever hired. If you’re honest with him, he will solve your problem. He was all business, and didn’t try to overcharge me at all.

Best lawyer I've had
I was in jail not even 48 hrs and had been visited by Mr Haslam, and for this specific case I had already had 3 attorney and non of them seemed to be able to help my case. But mr haslam got my 2nd class felony dismissed. I didn't even have to show up to court .And even when I was out of jail and after my court date he would check to see how I was doing. And give me legal advice. Best lawyer I've ever had
