About the firm

A family practice, still on the same work.

For over fifty years — beginning in 1959 — Delta Financial Services has handled accounting and financial services for business and individual clients.

The family-owned firm started with general accounting for several small businesses. As those businesses grew, Delta kept pace: tax planning, monthly financial statements, payroll, auditing procedures, and more.

President Emeritus Tasi and Gust — around 1975 — set a tone the practice still keeps. The work now sits with three generations in the room: Gust, John, and Constantine.

Today we are still changing and adapting so we can serve a broad base of clients. The reputation for comprehensive accounting and financial services — and a strong commitment to our clients’ financial well-being — is the foundation for the work we do now.

Three generations in the making. The goal has not moved: long-term relationships, professional work, and help managing business and personal financial matters.
