Reece Morrel Jr

Growing up around my father's law office, he never told me that I had to be a lawyer. Instead, he introduced me to a potpourri of bank presidents, big business executives, bookies, brain surgeons, car dealers, chiropractors, circus owners, doctors, dentists, farmers, Harlem Globetrotters, horse breeders, house wives, judges, machine shop owners, ministers, movie producers, oil and gas executives, orthodontists, petroleum engineers, plumbers, ranchers, restaurant owners, rocket scientists, salesmen, small business owners, video game developers, welders, winemakers, and zookeepers - just to name a few. But I soon understood the most important thing of all - they were people that just needed help.

For me, I realized that I enjoyed the variety of the challenges - "eating at the buffet" - since no two days were ever the same. And since I was really good at math and enjoyed puzzles, I decided to prepare myself for a such a career. I decided to become a lawyer.

After graduating from law school in 1991, I joined my father's firm. I did take a brief sabbatical in 1992-1993 to work for the Office of the Governor for the State of Oklahoma. While serving as the Director of Planning & Management Analysis, I designed the very first PC network implemented in the Governor's office. Our efforts also include the installation of Lotus Notes which was featured in a USA Today article in 1993.

As my father neared retirement, I decided to take my own advice and use a limited liability company. So, I started my own law firm and founded Morrel Law PLLC in August 2016.

So, how can I help you and your family today?

P.S. I love my job
