We are currently a one lawyer, two staff firm who helps people in need. We mostly help people who have been denied Social Security disability benefits and Workers’ Compensation benefits. We also do wills, probates, guardianships, adoptions, and general law work. We do not do criminal defense or divorces. We are a family business who strives to help.


Donald Horn graduated from Oklahoma State University in 1969 with a Bachelor of Science in Pre- Law. I graduated from The University of Oklahoma School of Law in 1973 with a Juris Doctor degree and was admitted to the practice of law in 1973. I worked for the City of Lawton for the first two years as an assistant city attorney and was Special District Judge for Grady County for three years. I have been in private practice since 1978. I started representing injured workers in workers’ compensation cases while an intern in law school. I represented by first social security disability claimant in 1979. I have tried more than 100 jury trials, approximately 1000 non-jury trials and hearings, more than 600 social security cases, approximately 800 workers’ compensation cases and thousands of miscellaneous legal matters. This practice has changed over the last five years to representing mostly Social Security disability claimants.


Karen Horn, my wife, received her certification as a Legal Assistant from The University of Oklahoma in 1991. She began working for me in 1984 as a bookkeeper and has worked as a Legal Assistant since receiving her certification. She is a highly skilled legal assistant who handles most matters without supervision.


Kristi Harris, our daughter, has worked for this law office since 2009. She was thrown into the Social Security disability world without training or experience. She has flourished in that role and now is able to navigate the complicated system with confidence and skill. She is the person who assembles disability files and deals with the local office and the hearing office. She is compassionate with clients.





Our mission statement is “ we change lives for the better”. Living up to that mission is our challenge every day. We are faced with increasingly uncaring government systems who claim to help people in need but actually works hard to deny deserving claimants every day. We go the extra mile to find the medical evidence necessary for our claimants to help them receive the benefits they need and deserve. You will talk to real people who are the same people who are working on your case. The lawyer who shows up at your hearing is the lawyer you have been working with. Every person you deal with is experienced and interested in helping you.
