The Withum OASyS Service Team has taken a proactive approach to help us understand our numbers which was a struggle with our old accounting firm. I appreciate the monthly catchup calls where Withum’s team makes it easy to have the tough but important conversations necessary to improve our business. We discuss financials, areas of opportunity and improvement, and cover any outstanding questions. The team is interested in our business, our current struggles, and our plans for expanding. Withum is truly our trusted advisor throughout our business’ journey.

Jessica A. Johnson

CEO & President, Johnson Security Bureau, Inc.

The team at Withum has been more than just our “accountants” from the start. They have been true business partners, valuable resources, and trusted advisors since our humble beginnings. Their skill set and knowledge when it comes to the cannabis industry and its specific regulations and tax complexities is unique and unmatched by any of the other top CPA firms. The services provided by their team are vast and they have stepped up throughout the years to provide dependable results. I would strongly recommend this team and their expertise to any business; their partnership has proven to be imperative to ours throughout the years.

Thomas Davis

CFO, INSA

From my first call with Withum, I knew I was in good hands. They explained the rules and procedures to me in detail and we came up with a plan to respond to the IRS. When it came time for me to testify, they prepared me for the most important questions and helped me focus on presenting the right message. I would highly recommend them to anyone facing an IRS audit.
