Calfee’s Insurance Coverage practice group serves corporate insurance policyholder clients, in Ohio and nationwide. Our principal purpose for more than 25 years has been to help our clients protect against and mitigate risk through the use of insurance. We collaborate with and counsel our clients on all aspects of their insurance coverage legal needs. Our core values are: creativity, focusing on the issues that matter, and attentiveness to clients.

To help manage and minimize the risks, losses, and liabilities that pose threats to our clients, Calfee’s Insurance Coverage attorneys provide advisory and claims services. We assist our clients with the placement and enhancement of their insurance policies, reviews of their existing policies, shaping and pursuing claims to get losses paid by their insurance companies, negotiating resolutions to disputed insurance claims, litigating coverage lawsuits against their insurers, and finding solutions for insurance coverage issues in corporate M&A deals. 

We have experience with a wide array of policy types, from newer products such as cyber and M&A representations and warranties insurance, to more traditional policy forms such as commercial general liability (CGL), umbrella, excess, property, D&O, professional liability, and EPL policies, to more specialized policies such as builder’s risk, liquor, and aviation.
