What Makes Us Unique
An award winning firm in Fairfax, Virginia
First, we listen to understand your goals and concerns, then we work with you to provide personalized services to meet your needs. Ratings from our existing clients earned us the 2017 & 2018 Best of Accounting™ Award for service excellence. Less than 1% of all accounting firms in the United States and Canada have received this honor.
Consistent, dedicated team year after year.
As our client, our goal is to assign the same personnel to your engagement each year—staff who know you and are committed to you and the firm. Our employee turnover rate is lower than normal for firms in this area. Based on scores from our employees, the Washington Post has selected us for their “Top Workplaces" award for many years. Staff members responsible for client service average over 20 years of public accounting experience with over 70% of that time spent with Thompson Greenspon. We value long-term relationships with our clients and employees.
Expertise competitive with national and regional firms.
We assist privately-held and closely-held family businesses with their business and personal needs by providing the resources and having the depth of expertise they need to grow. At Thompson Greenspon, 65% of our professional staff are experienced CPAs, substantially more than at the Big 4 accounting firms.
Industries we have specialized in since 1956:
Construction, real estate, and government contracting entities, professional service firms, and nonprofits are just some of the industries that seek our accounting, audit, and tax services, as do individuals.

Our tax concentrations include strategic tax planning and preparation, IRS representation, state and local tax representation, estate and succession planning, and international tax including transfer pricing studies.
