About Me

As a business owner for over 30 years, I know many of the issues and challenges facing small to medium sized businesses today.  Since budgets are tight, owners have a tendency to wait until a problem arises.  That may have been an acceptable strategy 20 years ago, but can be fatal today.  A single lawsuit can cripple a business and distract owners and key employees for months.  We try to establish long term relationships with our clients so that we can anticipate issues and deal with them before they become problems.  Accordingly, we regularly meet with our clients to ensure they are fully protected.  We encourage anyone interested in this approach to call us and see if we are a good fit.
