Leach & Sullivan

Founded in 1954, our firm and its experienced attorneys have been serving clients throughout southwestern Oklahoma for over 60 years. Lawyers from the Sullivan family have been practicing in the Duncan area since the 1920s, and their strong commitment to the local community carries over to the present day.

When you are working through a problem within the legal system, it is important to work with a law firm that has experience handling a similar problem or case that you face. At Leach & Sullivan, we have been serving southwestern Oklahoma for over 60 years, and with the addition of Patrick Sullivan, we now also serve Texas. We have built our legal practice on a foundation of competent and effective advocacy, with a commitment to giving each client the personal attention they need.
