History

Established in 1957.

William L. Zielinski founded Zielinski Companies in 1957 to serve religious and not-​for-​profit organizations. From the beginning, it was apparent to Mr. Zielinski that specialized services were needed to serve the unique needs of nonprofit organizations and faith-​based ministries. Although the company’s initial focus was on financial and accounting services, the scope of the firm’s offerings soon grew as client needs continued to evolve. Today, Zielinski Companies provides strategic planning and management consulting services to nonprofits in more than a dozen areas including financial and accounting, property and facility, staffing, office management, elder care, and fundraising advisory services.
