Core Values & Mission

Our Mission Statement

Anstiss & Co. is committed to being a premier provider of accounting, tax and consulting services. Our goal is to create success for our clients and our firm, while having a positive impact in the communities we serve.

The Anstiss & Co. Approach

Founded in 1964 in Lowell, Massachusetts, Anstiss & Co. has built a solid reputation in the Merrimack Valley and throughout New England. Our approach is different; we work as a team to fulfill our clients’ needs and build relationships that go beyond the surface of doing business.

Our accounting firm is proud of the dedication and expertise we bring to each client and each job with which we are involved. Our clients can rest assured that the extensive resources and experience brought to them by Anstiss & Co. means they are receiving high quality audit and tax services, as well as informed and reliable consultations for their business and personal needs.

Our goals of delivering the very best in accounting services and meeting our clients’ deadlines, while offering competitive pricing, ensure our clients are receiving optimal value. This is the way we do business, and the reason for our continued success and expansion of services beyond the Merrimack Valley.

What Makes Us Different

Value

We have the technical experience to compete with the larger national firms and the competitive pricing, staff, and service commitment to compete with the smaller local firms.

Consistency

Our firm has cultivated an environment that is progressive and rewards staff with increasing responsibilities. Accordingly, it is the norm to expect that the staff assigned to your initial engagement will continue to be involved in the delivery of key services to your entity.

Communication

We are available to assist you throughout the year, and encourage our clients to contact us whenever they have questions or are about to make any major decisions. We consider this part of our regular services, and our clients can take comfort in the knowledge that they will not receive a bill every time they call us for advice.

Experience

Our management team is highly experienced, which allows us to provide services which are both high quality and efficient.

Our Staff

Our most important asset is our team of professionals. Teamwork, integrity, and a commitment to understanding our clients’ needs are the keys to our successful and long-lasting relationships. With our low employee turnover rate, you can rest assured that year after year you will be working with a professional who fully understands your needs.

Anstiss & Co. currently ranked among the 30 largest accounting firms in Massachusetts by the Boston Business Journal. It is because of the dedication and performance of our team of professionals that we have been able to grow beyond the Greater Boston region.
