we're strategic trial lawyers & business dealmakers
Our goal? To deliver results that far outweigh the cost of our services.
At Calvert Law Firm, we don’t just take cases — we take ownership of outcomes. Whether navigating high-stakes litigation or guiding multimillion-dollar business transactions, we bring deep legal insight, sharp strategy, and the discipline to focus only on what moves the needle. We’re here to protect what you’ve built, fight for what you’re owed, and advise you like a true partner — not just another service provider.
Who We Are
Experienced Trial Attorneys Dedicated to Excellence in Law
Responsiveness Without Borders
When you need legal advice, time is essential. That's why we use state-of-the-art technology to ensure that our clients across the country receive the same personal attention and responsive service as our Oklahoma City neighbors.
Relationships That Endure
As a testament to our service, we have built long-term relationships with a broad base of clients, including individuals, small and mid-sized businesses, and Fortune 500 companies. While clients may come to us for help with a specific legal issue, they often return for ongoing advice and representation because they appreciate our integration of business acumen and legal knowledge.
Trusted by Clients and Colleagues
In fact, most new clients and cases are referrals from existing clients and other attorneys. Other lawyers frequently enlist our help in complex cases, and we are a premier resource for out-of-state attorneys seeking co-counsel in Oklahoma's trial and appellate courts.
Peer-Ranked. Results-Proven.
Additionally, our firm is in the Bar Register of Preeminent Lawyers in America. This rating is the result of a peer-review system based on the confidential opinions of practicing attorneys and members of the judiciary.
