Our Practices

Our attorneys have experience in the issues that business owners and entrepreneurs frequently face:
For nearly every type of business, real estate is a crucial component of success. For property owners, managers, developers and construction companies, commercial property issues are an everyday facet of business, and skillful solutions to those issues are essential to success of the business. Even if your company is not directly involved in the real estate industry, your place of business — whether purchased or leased — is a critical investment.
At Coolidge Wall, we understand how intimidating business issues like organization, internal governance and contract negotiation can be. As a client, you can expect our corporate and business lawyers to become thoroughly familiar with your business goals and operations. We then draw on the full experience of a distinguished staff of attorneys to help you make wise decisions for your business — from incorporation onward.
Litigation is one of the most challenging aspects of legal practice, one that not every attorney is prepared to handle. Coolidge Wall's team of seasoned litigators have experience with all types of disputes: civil and administrative litigation, appeals, and even select criminal matters.
At Coolidge Wall, we believe that a company’s workforce is its most important asset. However, managing personnel issues and striking the balance between attracting talent and keeping workforce expenses manageable can be a difficult and delicate task. Employers can easily make mistakes that lead to litigation, overcompensation or morale difficulties. Our labor and employment attorneys are well acquainted with labor trends and employment law and use that knowledge to provide our clients with creative and cost-effective advice.
The Ohio workers’ compensation system fills a legitimate need and was designed for administrative convenience. But for businesses of all sizes, workers’ compensation issues can be a nightmare. Employers trust the workers’ compensation practice team at Coolidge Wall to provide informed counsel and competent representation regarding these important issues.
Tax is a universal issue for every business in the United States. The record keeping, planning and preparation that is necessary to keep your tax affairs in order and avoid paying more than you should touches every aspect of your operation.

Our clients trust the attorneys of Coolidge Wall with their important estate planning and probate needs.  Our team is experienced in all aspects of estate planning and probate law, including wills and trusts, estate tax planning, probate administration, and business succession.

Our extensive transactional and civil work in the private sector has provided our team of attorneys at Coolidge Wall with the knowledge and practical experience necessary to provide public sector entities with competent legal counsel for a wide range of issues.
