Tronconi Segarra & Associates continues to be an important partner to Delaware North. Whether leveraging audit services, accounting expertise or staff augmentation, they are responsive, thoughtful and communicative. I have a tremendous amount of confidence that when I engage with them, we are getting top talent led by a strong, engaged management team.

Chris Lozipone

Senior Vice President - Finance Delaware North Companies, Inc.

The rapid growth of our business has resulted in added complexities within our finance area. This prompted the hiring of a controller, but we didn’t believe that a full-time CFO position could be cost justified. We knew, however, that a CFO skill set would be needed for certain functions such as strategic planning and mergers & acquisitions work. “Tronconi Segarra & Associates has provided us with the best of both worlds – a CFO skill set when needed without the price tag of a full-time CFO salary. I would highly recommend this service to growing companies that are not quite ready to commit to a full-time CFO.

William Hanes

Owner and Chief Executive Officer - Hanes Supply, Inc.

We have used Tronconi Segarra & Associates for six years to manage all of our corporate accounting work, from tax and audit services to advisory consultation with regards to acquisitions and business growth. Tronconi Segarra & Associates has become a valued partner with my company helping us run more efficiently and moving us forward as we continue to grow. The personal and courteous service of all Tronconi Segarra & Associates team members, the prompt answers to any and all questions, careful attention to detail, up-to-the-minute knowledge of current tax laws and advice have all been factors which have contributed to the continuous success at Seal & Design. I feel fortunate to have the hard-working people of Tronconi Segarra & Associates on my side to help drive our continued growth and future success.
