The Lesavich High-Tech Law Group, P.C., was founded by Stephen Lesavich, PhD in Chicago, Illinois in 2002. Dr. Lesavich left the partnership of a large law firm in Chicago to become an entrepreneur and start his own law firm.

The firm operated at 39 S. LaSalle Street until 2013, when the building was sold and converted into a new hotel.

Now operating as the Lesavich High-Tech Law Group, S.C., in new office space  in Kenosha, Wisconsin, the firm continues to counsel high-tech start-up, emerging and established clients in all areas of intellectual property law and business law.

The building at 39 S. LaSalle Street has an interesting history.

Originally  called the New York Life Insurance Building, it is a 14 story building that was designed by William Le Baron Jenney, it was completed in 1894. The building was sold in 2013 and converted from office space into the 281-room Kimpton Hotel which opened in 2016.
