“We previously used an accounting firm that didn’t understand how to accomplish what we needed. I spent most of my time managing the accounting of the business, leaving only a small amount of time for operations and growth. I realized I needed a partner capable of handling our accounting needs and came to Lance Ziaks CPA. Since taking over our accounting, all our filings are completed in a timely manner, proactively address any issues, and thoroughly understand my business and how to help it grow. I am now able to focus on expanding the profits of my business because I can spend more than 90% of my time on business growth.”  Retail Client

“We came to Lance looking for the right fit with a local accounting firm known for giving great service. We have found them to be an extremely good fit for our ministry size and philosophy. We receive personalized service and are freed up from worrying about things we don’t do well – accounting and bookkeeping – so that we are able to focus on our business.”  President – Local Business


“I began using Lance Ziaks CPA for my business in June 2013 and have been extremely satisfied with the services and personal attention that have been provided.
