About

n 1949, H.G. Siepert & Company was established in Beloit, Wisconsin. Since then, Siepert has grown to include more than 20 professionals and currently operates out of two offices. In 1974, our second office was established in Sycamore, Illinois followed by our Roscoe, Illinois office in 1994. In the fall of 2025, our Beloit and Roscoe offices merged together in a newly renovated building in Rockton, Illinois.

We believe in promotion from within and are proud to say that each of our partners began at Siepert as team members.  Only after proving their skills, abilities, and commitment to customer service were they promoted. While their job titles might have changed, their commitment to client service has always remained a priority.

We work closely with our clients to anticipate their needs and help guide their actions, providing significant value in the services we perform. We utilize state-of-the-art technology and clearly-defined processes to maintain quality and perform only services in our core competencies that our clients value and need.
