Editor's Review
VerifiedLawFirms editorialOklahoma roots and client base
Derryberry & Naifeh, LLP states that it has served Oklahoma City and communities across Oklahoma for more than 30 years. The firm works with individuals and corporate clients, including domestic and international clients. Its stated client base also includes government agencies, public utilities, trade associations and charitable foundations.
Education is another part of that client base. The firm names teachers' and professors' groups, schools, colleges and universities among the clients it represents. These categories point to work involving private interests, public bodies and membership groups.
The firm describes its size as a deliberate choice. It says its smaller structure retains resources associated with a larger firm. In my opinion, the named attorney roster and detailed practice list give prospective clients a useful picture of how that structure works.
Professional licensing and administrative matters
The clearest stated health care service is defense of medical licenses. The firm places this work within professional licensing and disciplinary defense. It also lists government relations and administrative law, two fields that can overlap with proceedings before state agencies and licensing boards.
What a licensing matter can involve
Medical licensing cases usually begin with a complaint, an agency inquiry or a formal notice. The license holder may need to review records, prepare a written response and address the rules cited by the board. Some matters proceed through interviews, conferences or a hearing before the licensing authority.
Board proceedings can affect a physician's license status and professional record. The governing agency sets deadlines, evidence rules and hearing procedures. Legal counsel in this field commonly studies the complaint, the relevant statutes, agency regulations and the client's records before preparing a response.
Derryberry & Naifeh specifically identifies medical license defense on its website. That stated service gives health care professionals a concrete basis for assessing the firm's work in licensing and discipline. The related administrative law practice also provides context for matters controlled by agency procedure.
Business, insurance and financial work
The firm's broader practice list includes business and professional services. It also covers insurance law, bankruptcy, workers' compensation and utility law. These fields can involve contracts, regulatory duties, disputed claims and formal filings.
Insurance claims and bankruptcy filings
The insurance practice includes bad faith claims and claim denials. Such disputes often turn on the policy language, the insurer's communications, the claim file and the reasons given for a denial. The timing of notices and responses can also shape how a claim proceeds.
For bankruptcy, the firm identifies Chapter 7 and Chapter 13 filings. Chapter 7 generally concerns liquidation under federal bankruptcy law, subject to eligibility rules and available exemptions. Chapter 13 uses a court supervised repayment plan for an individual with regular income.
A bankruptcy case commonly requires schedules of assets, debts, income and expenses. The debtor also submits information about creditors and financial transactions. The bankruptcy court, trustee and creditors each have defined roles under federal procedure.
Public utilities and workplace claims
Utility law fits with the firm's stated representation of public utilities and government agencies. Utility matters can involve rates, service obligations, permits or agency review. The firm's government relations and administrative law work may also concern rules and decisions made by public bodies.
The firm lists workers' compensation as a separate practice area. It also includes workplace accidents within its personal injury work. Those categories can call for different legal procedures even when they arise from the same event, since workers' compensation claims follow a statutory system.
Personal injury, real estate and estate matters
The personal injury practice names auto accidents, workplace accidents and premises liability. These matters often require accident reports, medical records, witness accounts and insurance documents. Liability and the extent of an injury can become separate points of dispute.
Auto accident claims commonly involve the conduct of each driver and the terms of available insurance coverage. Premises liability matters examine the condition of property, notice of a hazard and the relationship between the property holder and the injured person. The firm's insurance practice may be relevant when an insurer denies or disputes a related claim.
Planning, probate and property disputes
Estate planning and probate appear among the firm's main practice areas. Estate planning can include wills and trusts, while probate concerns court administration after a death. Estate administration usually requires attention to governing documents, asset records, creditor claims and distributions.
Real estate is another named field. Property matters can involve ownership records, title questions and disputes between people who claim an interest in the same land. Oil and gas interests can add another layer to title review because mineral ownership may differ from surface ownership.
Attorney roles and named experience
Four partners appear on the firm's roster: Donald B. Nevard, Douglas A. Rice, Darren B. Derryberry and Adam J. Singer. Stacey Steiner holds the title of associate attorney. The firm also names J. Eric Turner, Jerome S. Sepkowitz, Pete G. Serrata III, Kenneth T. McConkey, Grady Conrad and Charles P Rainbolt as of counsel.
This roster identifies three types of attorney roles within the firm. Partners hold the central leadership positions, while the associate and of counsel attorneys add capacity to the named team. As a reviewer, the clear use of titles helps readers understand the firm's internal structure.
Charles P Rainbolt's background
Rainbolt joined Derryberry & Naifeh as of counsel in 2022. His practice covers wills, trusts, probate and estate administration. He also handles real estate title matters, including oil and gas interests, plus quiet title and partition litigation.
Rainbolt gained admission to the Oklahoma bar in 1974 and also gained admission to practice before the U.S. Supreme Court. He earned his J.D. from the University of Oklahoma College of Law in 1973. He also holds a B.A. from the University of Oklahoma.
Quiet title litigation asks a court to determine competing claims to property. Partition litigation concerns division or sale when multiple owners hold interests in the same property. Rainbolt's stated work connects estate matters with the title questions that can arise when property passes between owners or beneficiaries.
Continuity and firm history
The firm's history spans more than three decades of service in the Oklahoma City area and across the state. Its current practice areas cover private disputes, agency proceedings, financial cases and planning matters. The roster combines partners, an associate attorney and several of counsel attorneys.
The firm's homepage also records two memorials. Larry Derryberry lived from 1939 to 2016. Robert N. Naifeh, Jr. lived from 1957 to 2020.
