Senior Counsel

Attorney Estner’s practice focuses on providing legal services to owners of small and medium-sized privately owned businesses.

These clients often are preparing for the next phase of their development.  Services include helping clients to evaluate alternatives such as obtaining additional capital, acquiring or merging with a related small business, changing or adding a location, adding executive personnel, or putting an ownership transition plan into effect.  The legal advice and its implementation reduces risk, improves success, and increases the value of the company.

A business problem is a set of circumstances that interferes with accomplishing goals.  A legal problem is just another type of business problem.  It must be viewed through the client’s needs.  A focus on a client’s goals is a necessary part of defining the problem.  Once defined, the application of creativity, negotiating skill, and commitment can be brought to bear on the solution.
