Robert S. Vihon

Founding Partner 1952-2020

On May 2, 2020, we lost our friend and mentor, Rob Vihon.  Rob will be missed by all who knew him. Rob’s passion for his work and his commitment to his clients serve as an example to all in the legal profession, and especially to those of us who were fortunate to work with him at Worsek & Vihon.


ROBERT S. VIHON teamed up with Richard D. Worsek in 1983 to form the Worsek & Vihon law firm. Prior to going into private practice, Mr. Vihon worked as a Cook County Assistant State’s Attorney (1978-1983) in the Real Estate Tax Litigation and Chancery Litigation Divisions where he tried many contested valuation and exemption real estate tax cases. He also litigated class action matters, drafted appellate briefs and argued various cases before the Illinois Appellate and Supreme Courts. Mr. Vihon lectured before professional organizations on real estate tax legal issues, real estate tax incentives and abatements. In 1995 he was an adjunct professor at John Marshall Law School’s Real Estate Law LLM program. He was a member of the Chicago and Illinois State Bar Associations; the International Association of Assessing Officers; the Institute of Professionals in Taxation; Taxpayer’s Federation of Illinois; and the Executive Committee and Tax Committee of the Civic Federation.

For over 20 years, Mr. Vihon served as a board member, president and trustee of the Center for Enriched Living, a center enriching the lives of citizens with developmental disabilities. Mr. Vihon graduated from the University of Illinois with high honors with a Bachelor of Science and attended law school at Illinois Institute of Technology, Chicago-Kent College of Law, where he received his J.D. in 1977.
