We thank you for your patience and cooperation.

We have dealt with Giffen for many years and have a strong relationship with the firm and its people.  We always found the lawyers and staff of Giffen to be not just highly skilled, but very personable, responsive and easy to deal with.  As a family owned multi–generational business, we found the firm's support, service and advice to be invaluable

Our association with Giffen goes back more than 20 years.  The various members of the Giffen team who have worked with and for us over the years have always shown an excellent understanding of our needs and being creative and flexible in approaching solutions.  Their professionalism, time sensitivity and concern for our family has always been evident in our dealings with the firm and their fees have always been fair.  I have no hesitation in recommending them as outstanding corporate legal counsel.
