Reston, VA - Continuing its tradition of more than 25 years, INSIDE Public Accounting (IPA) has unveiled the 2018 list of the Best of the Best public accounting firms in the nation including CST Group, an accounting firm based in Reston, VA.


The Best of the Best firms are the highest performers within the profession, ranked on more than 50 metrics. These companies produce superior financial results while planning for long-term, sustainable growth. They represent the top 10% of all firms that participated in the 2018 IPA Survey and Analysis of Firms. IPA’s proprietary scoring formula looks at a variety of metrics related to growth, income, productivity, tools of governance, staff turnover, time management and other areas that speak to the framework of the firm to determine the Best of the Best.


The IPA Best of the Best firms are presented in three categories:

  • Best of the Best above $5 million in revenue (50 firms ranging from $5 million to more than $600 million)
  • Best of the Best under $5 million in revenue (10 firms ranging from $2 million to $5 million)
  • Best of the Best in Canada (five firms ranging from $7 million to $30 million)

“Most firms don’t aspire to be average. Best of the Best firms are the peer group to which progressive firms aspire,” says Michael Platt, principal of the Platt Group and publisher of IPA. “In presenting the results of the IPA Best of the Best, we are proud to continue the tradition of expanding the imagination and the understanding of what is possible to achieve in running a public accounting firm.”


CST Group was also named to the INSIDE Public Accounting 2018 Top 300 Firms list. This is the third consecutive year that CST Group has been given this honor, demonstrating an impressive commitment to excellence and sustainability. They represent what is possible in a public accounting firm and are the peer group that high-performing firms can benchmark themselves against.
