About Us

At Guinan Bisonet, we are interested in our clients - their problems and their opportunities.  We work hard to truly understand our clients and their business.  We know that the best legal advice demands a holistic rather than clinical approach.

We're lean and responsive - adapted to today's economic realities.  Our client's legal dollars go toward advancing their legal interests.  Our clients aren't paying for mahogany wall paneling or acres of fancy real estate and neither should you.

We work for you.  We're available when you need us.  We can help you.
