Our Approach To Serving You

Regardless of your business size or the complexity of your accounting needs, Johnson O’Connor will provide professional, personalized service and high-quality, value-added business guidance that goes beyond standard accounting practices.

Success Is Based Not Just On Numbers

For us, success is based not just on numbers, but helping you achieve your financial goals and aspirations, whether that is growing your business, building personal wealth, or both. Through an integrated, long-term partnership, our caring professionals will work collaboratively for the common success of our clients, employees, and the community.

Our Philosophy

At Johnson O’Connor our philosophy is to deliver accounting services in a personalized, caring, and helpful manner. While our high-level expertise and experience can match many of the larger accounting firms, you’ll find working with us to be a very different experience – one that’s individualized, collaborative, respectful, and responsive. You’ll always be able to reach us, and we’ll return your calls promptly.


Johnson O’Connor has come a long way since 1945 when Russell S. Cary opened a modest, local accounting firm, which focused on tax services for small businesses and nonprofits.

Present Day

Today, Johnson O’Connor is a leader among New England accounting firms recognized for our high level of accounting experience, trusted long-term client relationships, deep industry expertise, and proactive business guidance. As a firm committed to delivering beyond expectations, we are always looking for new, creative solutions to add value for our clients and their businesses.

Core Values





The environment we’re trying to create here is one that transcends the work. We encourage folks to contribute in a lot of different ways. Obviously client services is one of those ways, but beyond that in terms of running the firm, we want to have as many voices at the table as possible.
