Duffy Kruspodin, LLP has been our lifeline for developing our businesses for for over 30 years. We wouldn't think of changing direction or making a major decision without their sage advice. Our relationship through the years has been extraordinary. We are genuinely grateful for all the assistance they’ve given us through the start-up, expansion and sale of our companies.

DK has handled my business, personal and family accounting needs for almost 20 years. In that time DK has become a very trusted business partner not only providing excellent accounting services but financial planning, business strategies and consultant services. DK has earned my trust throughout our continuing relationship.

DK has been a trusted partner from the very first day that we are with them. They have always been one step ahead of us in our accounting needs for our rapid growth.
