    Brookfield-based public accounting and consulting firm Kolb+Co. has merged with Naperville, Ill.-based Sikich LLP, a leading professional services firm. The merger, which was effective August 1, has resulted in Sikich operating its first Wisconsin-based office, which is now the firm’s second-largest office throughout the country.


    “We are very excited to join the Sikich team,” said Tom Luken, partner-in-charge of the Milwaukee office. “Through this union, we will be able to offer our clients expanded industry capabilities and a full suite of advisory and technology services, as well as access to additional talented and experienced professionals. Sikich’s commitment to service excellence will be a perfect complement to what we have built during the past 53 years. We look forward to utilizing these resources to benefit our clients and grow our presence in Wisconsin and Northern Illinois.”


    As a result of this merger, Sikich has been able to enrich its public accounting and advisory services with new resources and top talent. The firm now boasts more than 500 employees, including 87 partners, with expertise in auditing and accounting, advisory services and technology. Additionally, the added growth will diversify the firm’s breadth of services, enhance its capability to service more markets, and provide expanded client opportunities in industries such as manufacturing, distribution, non-profit and government.


    “Merging with Kolb+Co. was a seamless process, and we are confident that the transition has and will be just as positive and comfortable for clients,” said Jim Sikich, CEO and managing partner of Sikich. “As one firm, we have already begun collaborating on client projects, giving the Milwaukee team the opportunity to fully integrate into our existing accounting and advisory teams. This joint endeavor will ultimately allow us to not only continue our rapid growth, but also help our clients reach their long-term goals.”


    Sikich History

    Throughout most of Sikich’s history, the firm appeared much like other traditional public accounting firms, providing accounting, tax and general consulting services. By the mid-1990s, Sikich reached a juncture where it could either continue to operate along the conventional lines of a CPA practice or begin to create a dynamic professional services firm that would encompass a broader array of skill sets and open market potential.


    In 1996, Sikich partner launched the firm in a new direction—one that would have far-reaching consequences for business, employees and clients. By expanding into non-traditional service areas, Sikich became a true multi-discipline, professional services practice.


    During the ensuing decade, Sikich experienced exponential growth and became one of the country’s 50 largest CPA firms. Today, the firm is in the Top 40 largest CPA firms. Sikich still has a strong backbone in public accounting, while at the same time consisting of a large technology practice and a multitude of advisory services including business valuation, human resources and more. Like many successful enterprises, Sikich continues to evolve and expand its capabilities—adding new services, enhancing technical proficiencies and extending geographic reach.
