Our Services

Audit/Assurance

Audits, reviews, and compilations serve as essential financial reporting tools to deliver a clear, comprehensive picture of your business’s financial health. In today’s environment of heightened accountability — to stakeholders, lenders, investors, and regulators — the accuracy, completeness, and reliability of your financial statements are more critical than ever.

Tax Planning/Preparation

Major financial decisions in your business and personal life — such as investments, expansions, property purchases, or retirement planning — can significantly impact your tax position for years to come. Proactive tax planning is essential to uncover the most effective strategies under current tax laws, helping you minimize liabilities and maximize long-term wealth preservation.

Business Advisory/Consulting

As an entrepreneur, you thrive on bold ideas, calculated risks, and turning the impossible into reality. Wearing multiple hats to drive your vision forward is part of what makes you exceptional — but it can also be overwhelming. We can provide, and/or direct you to expert guidance, objective insights, and strategic support from seasoned professionals who understand the unique challenges and opportunities of innovative business owners like you.

Services Offered in Conjunction with Strategic Partners

In today’s complex financial and regulatory environment, specialized needs sometimes require expertise beyond traditional accounting and tax services.  We partner with a trusted network of strategic professionals — such as attorneys, financial advisors, insurance specialists, appraisers and industry specialists — to deliver seamless, comprehensive solutions while you continue working with your dedicated CPA team.

What Clients Are Saying…

He has been there to answer all my questions…”

Coming from out of state with a rental property, a corporation, a medical practice and the loss of my husband, Roger was able to make sense of my financial situation and personal set-backs. He has been there to answer all my questions and navigate all my returns. I am amazed and grateful to have found such an amazing accountant.

“I highly recommend Roger and will continue to do business with him in the future…”

Roger Rossmeisl is, in my opinion, the best choice for automotive dealership Accounting and Auditing in the marketplace today. I have worked with him on a few challenging projects and he offers sound tax advice, best practices for maintaining accurate and timely records, and will fully research any questions that may have more than one option to ensure his clients are making informed decisions. He understands dealerships’ accounting and taxes better than most CPA’s I have had to work with in the past.

Very Important Quality – He never seems to get rattled and is quite pleasant to work with, even when the situation is not ideal.

He handled my personal Tax Return as well when I relocated to another state and helped me through the transition.

I highly recommend Roger and will continue to do business with him in the future. If you are less than satisfied with your current level of service, do yourself a favor and meet with Roger. You may find your next CPA!

“Roger is always my go-to professional…”

In the nearly two decades that I have known Roger, he has, repeatedly, proven himself an invaluable treasure trove of knowledge and skill in every aspect of tax law and finances. He is also self-driven, detail-oriented, and honest. I am truly honored to know Roger both professionally and personally.

As someone who is self-employed and runs several businesses, I often find myself in challenging financial situations, where I require insight and advice from someone skilled in the nuances of taxation. Roger is always my go-to professional. Sometimes my questions and issues are novel and demand research. Roger consistently finds the answer.

Aside from his unequalled professionalism, Roger is also a super nice guy, whose integrity, empathy, and compassion, shine both in his business and personal lives. I am honored to call him both “colleague” and “friend.”

Roger is a high level skilled professional. I have worked with Roger on multiple projects as a client. When complex issues arise Roger finds a creative way to resolve these issues that adhere to and comply with the ever-changing accounting principles and tax laws. I’m thankful that Roger is part of our corporate team and would strongly recommend him if you’re a startup or a long-existing corporation he will help you facilitate and grow revenue streams in areas that were not previously considered. What’s critical is that Roger takes a proactive approach to accounting and or tax law changes that directly affect your industry, enabling one to make well-informed decisions while getting ahead of any potential problems that may arise out of these changes. I’m so thankful that Roger is on our team.
