“ADC has been a trusted partner in our manufacturing operation since we moved to Newburyport 35 years ago. Throughout many life/business events they have been the source of great advice and knowledge. We have complete confidence in the ADC team and are very grateful for the crucial role they have played in the growth of our businesses.”

“We have been working with ADC for years for their auditing and tax services. Their staff is very professional, knowledgeable and responsive to all our needs. As a medium-size domestic business with a foreign parent company, they take the time to understand our business and help us continue to make wise decisions. Due to their thoroughness and due diligence on serious matters, I would highly recommend them to other companies.”

“I have been working with Ambrosi Donahue Congdon & Co. P.C. for over 33 years. When we first began our long-term business relationship we were a newly established business just starting out in our successful journey. They have been key members of our team on many levels working with us on; internal controls, financial statement preparation, tax planning, deficiency free IRS, Sales & Use Tax, and Payroll Tax audits.

In addition, their team has been instrumental in guiding us through start up of new corporations located in multi states, sale of corporations, partner buyout due to retirement, and corporate real estate purchases. I am confident that whatever issue we encounter, the professional staff at Ambrosi Donahue Congdon & Co. can guide us through it. They are knowledgeable, engaging and proactive. A well-rounded accounting firm who has been a true partner instrumental in the growth and success of our company.”
