Firm History – Six Decades Of Commitment To Duncan And Southern Oklahoma
Our firm was founded in 1954 by William O. Leach, Paul D. Sullivan, and Patrick D. Sullivan. The family tradition continued with Michael P. Sullivan joining the firm in 1972 and Kent P. Sullivan joining the firm in 1981. After William O. Leach passed away in 1990, longtime Duncan resident Jay B. Watkins became a partner after joining the firm in 1987.
We have served our community for generations, and are proud of our well-established reputation in the legal profession and the community at large. We continue to be involved in community activities, such as providing pro bono legal advice at Legal Aid, membership in the Kiwanis, work for the United Way, support of local sports teams in Duncan, and donating funds to the Duncan Public Schools Foundation and the Project Graduation lock-in.
Treating Our Clients Like Family
We cultivate personal relationships with our clients and encourage them to refer their family and friends to our firm for continuing legal needs. Indeed, many of our clients are referred to us from other satisfied clients, as well as other attorneys, and many of these clients choose to continue allowing us to represent them for the various legal issues that arise through the years.
We are an old-fashioned firm that believes in responsive attention to our clients’ needs. We prefer to meet with clients face-to-face – and we strive to develop a relationship where our clients are on a first name basis with the attorneys and staff.
