The employees and partners of Sisterson work out of one office, in the Grant Building, in downtown Pittsburgh. This lends to a collaborative environment which is a benefit to our clients.
Sisterson has grown over the years, not due to mergers or acquisitions, but to work from new and existing clients and maintaining our talent base. An important part of our growth has been providing a challenging, yet rewarding, experience for our staff, helping us maintain consistent client service and a pipeline of talent for the future.
Our professionals are more than accountants. They are client advocates who look beyond the numbers, ask questions, and offer solutions. From partners to associates, the Sisterson team is there for our clients and cares about their success. We believe in being reliable, doing the right thing, and keeping our word to always deliver what we promise.
Because we have been in business for more than 90 years, our professionals have dealt with scores of issues. Over the years, our firm has successfully adapted to changes in the world and in our industry. Through successful succession, we have grown and prospered, and so have our clients.
We are always looking for ways to serve our clients more effectively with continuous training. This commitment has lead to the firm's favorable reputation for outstanding technical capabilities.
Sisterson is a member of AGN International, a worldwide association of separate and independent accounting and advisory firms.
