1902: Crowe & Dunlevy began when Charles Edward Johnson (1870-1950) opened the first law office in the Oklahoma Territory at 131 ½ West Grand (now Sheridan Avenue). The Westin Hotel stands at this location today. "Olie" Johnson was an emigrant from Sweden who graduated from the University of Texas Law School (LL.B., 1901).

1905: The Firm made its next move to Oklahoma City's first "skyscraper," the six-story Lee Building at the northeast corner of Main and Robinson.

1907: The Firm name became Burwell, Crockett & Johnson when Benjamin F. Burwell (1866-1916) joined the practice of law. Judge Burwell had been an Associate Justice of the Supreme Court for the Territory of Oklahoma, serving from 1898 until statehood in 1907. Some of Judge Burwell's books are still in the Firm's library today.

1916: John Embry (1869-1960) joined the Firm, and its name became Embry, Crockett & Johnson. He had served as the U.S. Attorney for the Territory of Oklahoma and later for the State from 1907-1912.

1918: The Firm name became Embry, Johnson & Kidd when Chester P. Kidd joined in the practice of law. He retired in 1922 due to illness.

1922: The Firm name became Embry, Johnson & Tolbert, and the office moved to the Medical Arts Building at the southwest corner of Park and Broadway. Raymond A. Tolbert (1890-1960), a Texas native and a graduate from the University of Oklahoma School of Law (LL.B., 1913), was the Firm's Managing Partner until his death.

1927: The next move was to the Perrine Building at the southwest corner of Park and Robinson.

1929: Vincil Penny ("V.P.") Crowe (1897-1974), a graduate of the University of Missouri, joined the Firm, and the name became Embry, Johnson, Crowe & Tolbert. "V.P." had been Garfield County Attorney in Enid, Oklahoma, and Assistant Attorney General for the State of Oklahoma.

1932: The First National Building was completed this year, and the Firm moved to Suite 640 at the southeast corner of Park and Robinson.

1943: The Firm name became Embry, Johnson, Crowe, Tolbert & Shelton to include its partner, Troy Shelton.

1953: "Olie" Johnson's name was dropped from the Firm name because of his death in 1950, and the name of Bruce H. Johnson was added to form Embry, Crowe, Tolbert, Boxley & Johnson. (The two Johnsons were not related.)

1958: The Firm moved to a new addition to the First National Building, 120 Park Avenue.

1961: After the deaths of John Embry and Raymond A. Tolbert in 1960, the Firm's name became Crowe, Boxley, Dunlevy, Thweatt, Swinford & Johnson. Fred W. Dunlevy had joined the Firm in 1937, C. Harold Thweatt in 1944, and John W. Swinford in 1946.

1967: The next move was to the 100 Park Building, which had been the Firm's address in 1922 when it was known as the Medical Arts Building.

The Huckins Hotel originally occupied this site at Main and Broadway and was known to be the first capitol building in Oklahoma City.

1989: To meet the needs of its Tulsa clients, Crowe & Dunlevy opened an office in Tulsa, Oklahoma.

White Collar Crime


Expertise in white collar criminal law has become a necessity given the increasing number of matters that are being handled in the criminal forum.  Crowe &Dunlevy has the people and expertise to handle any white collar criminal matter.  The Firm has handled many high profile criminal trials and has a well deserved reputation for vigorously defending clients in court.  However, the Firm is also proud of the many instances when we have been able to discreetly convince the government that particular matters were not appropriate for the criminal forum and the matter never reached public view.

Our approach is to use the broad expertise within the firm to assemble the best team possible to handle all aspects of a client’s legal problems.  We are well positioned to respond rapidly and with the right expertise when the situation warrants.  The credibility we have with government officials and courts allows us to represent our clients most effectively.

Our Expertise.  Our White Collar Crime group includes motivated lawyers with experience and success in handling white collar criminal matters.  Our team includes a former United States Attorney, two former District Attorneys, a former Deputy Attorney General, a former military prosecutor, a former Associate Counsel in the Office of Independent Counsel, and former government regulators who can provide needed expertise on government practice.  Additionally, the team draws on the expertise within the firm applicable to the particular case, such as tax, securities, antitrust, bankruptcy, health care, government ethics, environmental law, governmental procurement, and financial institution law.  Our lawyers have extensive experience defending investigations by federal and state law enforcement, as well as by regulatory agencies such as the Securities and Exchange Commission, the Internal Revenue Service, the State Ethics Commission, the Office of the Inspector General, the Environmental Protection Agency, the Oklahoma Department of Environmental Quality, the Oklahoma Board of Pharmacy, and the Oklahoma Medical Licensure Board.  

Our lawyers have handled cases in the following areas:

 • Public Corruption
 • Campaign Finance
 • Securities Fraud
 • Financial Institution Fraud 
 • Foreign Corrupt Practices Act
 • Government Purchasing
 • Pharmaceutical Regulation
 • Tax Fraud
 • Health Care Fraud
 • Bankruptcy Fraud

Parallel Civil and Criminal Proceedings.   Criminal investigations frequently overlap with ongoing civil law matters.  Experience and foresight are critical to managing both the civil and criminal law aspects.  Crowe & Dunlevy’s blend of criminal and civil attorneys makes us particularly well positioned to handle parallel proceedings.

Internal Investigations.  We have conducted numerous, sensitive internal investigations for our clients.  We focus on the need for such investigations to be timely, complete, accurate and discreet.  The Firm has also been active in working with clients to prevent relatively minor crises from developing into a more serious problem than necessary. 

Compliance Plans.   We have implemented compliance plans for many clients, both large and small.  The experience gained from our lawyers who have previously worked as prosecutors has been a key ingredient to designing and implementing compliance plans that will achieve the client’s goals.  Our compliance plan process begins with an in depth analysis with senior management of the risk factors.  We use our expertise in different areas to design a compliance plan which will be effective for the particular needs of the client and will also satisfy legal standards.
