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.
