When Corey sits down with a client, he understands that there is no simple formula, that every client’s situation is unique and requires a proactive, innovative legal approach. Corey enjoys working closely with clients to identify a clear set of goals, to develop a plan to meet those goals, and, regardless of what unexpected curveballs arise, to effectively execute that strategy.
Since arriving at Grant & Hoffman, P.C., Corey has specialized in the following areas:

Employment Law and Civil Rights:

Corey has developed a thriving employment practice, handling discrimination claims before the EEOC, as well as claims under the FMLA, wage and benefit claims, and a broad range of state and federal civil right statutes. Corey has been successful negotiating strong and speedy settlements for clients, securing favorable determinations from the EEOC, and developing discrimination claims for trial. A transplant from William & Mary School of Law in Virginia, Corey’s first legal position in Colorado was working closely with an EEOC administrative law judge in Denver.


Since arriving at Grant & Hoffman, P.C., Corey has developed a busy litigation practice. He has engaged in intellectual property litigation, high-stakes business disputes and a range of contractual and tort actions. Corey presently represents everyone from oil and gas businesses, to large-scale farm operations, to individuals pursuing contract rights via litigation. He recognizes the litigation process can be complicated, and he prides himself on working closely with clients to navigate that process and to develop winning and cost-effective strategies.

Business Development:

Grant & Hoffman enjoys close ties with countless businesses in Northern Colorado, from promising startups and small shops, to decades-strong staples of the community and large operations with an international presence. Corey’s clients include cutting-edge engineering firms, agricultural producers and support businesses, active businesses from every corner of the oil and gas industry, and a wide range of businesses in the manufacturing and service industries. Working closely with these businesses on a range of issues – including business structure and development, contract development, employee relations and protection of trade secrets – and helping local business owners grow and thrive, is one of the most satisfying aspects of Corey’s practice.

Transactional Work:

Corey specializes in crafting tight, effective contracts for his clients, and has structured business and asset purchase contracts, joint venture agreements, employment contracts and a range of other essential business agreements. Every business deal or contractual relationship is unique, and the best contracts both reflect the client’s immediate needs and goals, and build in a layer of protection against unforeseen circumstances that may arise long after the agreement is signed. Corey tailors his contracts carefully, knowing that boilerplate language rarely covers the nuances that are most important to his clients, and he collaborates with his clients to make sure that each of those specific concerns are fully and effectively addressed.

Oil and Gas:

The oil and gas boom in Northern Colorado has created a robust and active environment where everyone from multinational corporations to individual property owners often seek legal advice. Grant & Hoffman has worked to put itself at the center of that flourishing environment, and Corey specializes in contractual work for oil and gas services, mineral leases and purchase agreements, and land use and development. Corey works with clients to both maximize their involvement in the oil and gas industry, and to protect their interests if need be.
