Upholding the highest standards
of professionalism

CPAs Frank Keilman and Dennis Austgen began their careers working for large Chicago firms. Their collective desire to be more hands on and personally involved with clients led to the opening of the Merrillville office in 1984. Theodore Sinal, Jr. joined the firm shortly thereafter. Carol Hughes joined the firm in 2002 and is the most recent partner.

Our first clients were small retail and medical businesses that saw the value of retaining the expertise of a large accounting firm with the personal service that remains our hallmark today. We continue to maintain a strong system of quality control and subject those controls to external review by other CPA firms, ensuring we exceed the high standards of professionalism required by our industry.

Staff has grown to include CPAs Debra Waisnora, Marti Sapp, and Michael Tomaszewski as well as professional accounting and administrative personnel. We're all committed to rolling up our sleeves and working with you to provide the highest level of personal and professional accounting services.

Keilman, Austgen & Sinal is a member of the American Institute of Certified Public Accountants (AICPA) and is licensed in the states of Indiana and Illinois.

All CPAs are members of the AICPA and the Indiana CPA Society. All CPAs and accounting professionals undergo continuing education to ensure we maintain the high level of knowledge our profession requires.
