About

For most business owners, your CPA is your primary trusted advisor when it comes to the financial success of your business. We treat all of our clients with personal service and expertise, building long-term, client-focused relationships.

Our goal is to provide quality accounting, auditing, tax preparation and business consulting for small to medium sized firms. We care about your success and take the time to know and understand your business and individual financial needs. Our depth of experience enables us to deliver personalized service to help you achieve your goals.

Why Work with Our CPA Firm?

We offer the breadth of services clients get with larger accounting firms but with more personal attention. What sets us apart is that we provide the most experienced team on every client account and we save our clients money.

When we ask our new and prospective clients, what do you pay your accountant for? The most common answers we received were: "To figure out my taxes for my business" or "So that my business stays compliant."

Although this may be the initial reason business owners hire a CPA, over time, hiring an accountant should contribute to your peace of mind. When you work with John Harmon, CPA, we get to know your business intimately so we can provide advise and support whenever you need it.

Working Ownership

John insists on offering his high level of expertise to every one of his clients. The result is more a thorough, accurate, higher quality end product.

Also key is John's practical business knowledge formed in working from a young age in a successful family business that grew to 100 employees.
