About Us

An Established Full-Service Law Firm

Since the mid-1980s, the law firm of O'Reilly Rancilio has provided cost-effective legal counsel and litigation services in southeast Michigan and statewide. We have built a reputation as the go-to law firm for complex matters, including large regional and national clients relying on our firm for qualified local counsel.

The firm has a diversified general practice, with a strong focus in the areas of banking (loan documentation and workouts), business transactions, creditor's rights, commercial litigation, municipal law and school law. Our clients include regional and community banks and finance companies, closely held and publicly held businesses, local government entities, and school districts. We provide estate planning, probate, and real estate services to business owners and other individuals.

Building on a Foundation of Excellence

The firm was founded in 1984 by Paul J. O'Reilly, Kenneth L. Rancilio and John A. Nitz. Paul O'Reilly (1940 – 2003) was one of the State of Michigan's leading municipal lawyers and represented the City of Sterling Heights from its formation in 1968 until his retirement. In addition, he maintained an active civil litigation practice. Ken Rancilio (1939 – 1998) was also an active civil trial lawyer who represented numerous individuals and institutions throughout the State of Michigan. John Nitz is a leading business and estate planning attorney and remains in active practice and serves as the President of the O'Reilly Rancilio law firm. He recently served as the general counsel to the Macomb County Charter Commission in connection with the Commission's drafting and adoption of the County's proposed charter which was approved by the electorate in November 2009.

With more than 20 attorneys and an experienced and dedicated support staff, we have evolved into a right-size law firm that applies technology and modern methods to deliver the cost-containing solutions critical in today's challenging economic conditions. While our accomplished lawyers have the in-depth experience and courtroom skills to match the large Detroit firms, our cost structure is substantially lower through judicious use of associates and legal assistants for those tasks not requiring an attorney. Our firm eliminates layers; our senior attorneys are not only accessible but directly involved in every client matter.

Our firm takes great pride in the professionalism, dedication, and enthusiasm of its attorneys. The members of our firm have a solid reputation with judges, business leaders, and elected officials in Macomb County and statewide. Many members of the firm have represented municipalities of southeast Michigan, business and individuals for decades. Our attorneys and staff are actively involved in various professional organizations, including committees of the national, state, and local bar associations. Concerned about their community, members of the firm have also allocated time to service clubs, school foundations, Chambers of Commerce, Kiwanis, and Rotary groups and other personal and professional volunteer activities.

We recognize that the practice of law is a personal service business, even in commercial litigation or in representing large institutional clients. At O'Reilly Rancilio P.C., clients can expect our undivided attention to their legal matter and a commitment to competence, timeliness, consideration and economy.
