No. 01 — Who We Serve
We work best with these types of business owners.
Wherever your business sits today, we have a division built around the work you actually need.
Commercial Division
Established Companies
You are a $5M+ business with bank financing, covenants to meet, and a finance team that handles the day to day. You need a CPA who can review financial statements, plan for tax, and weigh in on the bigger decisions before they hit the books.
Commercial Division
Closely Held Companies
You are a $1M to $5M business, running a tight operation, often with a controller or bookkeeper inside. You want strategic tax planning, clean monthly reporting, and a sounding board you can actually reach when something comes up.
Commercial Division
Growth Stage Companies
You are three to five years in, building fast, and ready to put a real financial foundation under the business. We help you set up the right systems now so you do not have to untangle them later.
Government & R&D Division
Research Start Ups & Government Contractors
You are a federally or state funded business, a venture-backed R&D company, or are advancing your research to commercialization. We simplify federal compliance and strategic business modeling.
No. 02 — Who We Are
Fifty years, one firm, built around the businesses we serve.
Founded in 1974 in Newburyport, ADC began as a small homegrown firm serving local citizens and businesses of the North Shore. We now have clients in all 50 states. In 2022, Anthony Rita and Brittany Leary took over ownership and have been steadily reshaping the practice around year round, advisory style relationships with owners who want a CPA in the loop, not on the sideline.
Strategic thinking. We look ahead, not just at last year.
Real collaboration. Steady, two way conversation between us and you.
Trust and integrity. Plain answers, even when the answer is hard.
Services
A full service firm, built for year-round work.
Compliance is the floor, not the ceiling. Every engagement starts with your books and ends wherever your business needs us — tax, audit, or a seat at the table on the decisions in between.
No. 01 — Core Services
Where the work starts.
Bookkeeping & Monthly Accounting
Clean books that close on time, every month. We manage the day to day so your financials are accurate, current, and ready whenever you — or your bank — need to look at them.
Tax Planning & Preparation
Forward looking strategy plus accurate, on time returns. We plan for tax before year end, not after, so there are fewer surprises in April.
Audit & Assurance
Financial statement audits, reviews, and compilations done right for your bank, your investors, and your peace of mind.
Advisory & CFO Support
A finance partner you can call before you make the decision, not after. We weigh in on pricing, financing, and growth planning alongside your leadership team.
Trust & Estate
Coordinated tax and reporting across your business and your family, so personal and corporate planning move in step.
Research & Experimentation Tax Credits
Identifying and documenting R&D credits your business has earned but may not be claiming in full.
