ATKG & SPR join forces, creating SA’s largest local accounting and advisory firm.

unique

At ATKG, our business is built around the client experience because our clients deserve the best and it’s how we set ourselves apart from other professional advisory firms.

Our Commitment to Our Clients
Building Relationships to Provide Insightful Solutions
Since 1982, ATKG has specialized in tax, accounting, assurance and advisory services for a select client base of closely held businesses and large family groups. We are a hands-on firm that has built a business around the entire client experience, not just the result.

To ensure the perfect partnership, we limit the number of clients we have at any given time, so that trusted and lasting relationships have time to develop and grow. Our clients look to us not only for technical expertise, but also because of our deep understanding of their areas of professional and personal interest.

We believe you not only deserve specialized attention but that you should expect it when working with an professional advisory firm. Our all-star lineup of professionals collaborates every step of the way to support your financial and life goals and that’s exactly how it should be.
