Jonathan Sierakowski

In January 2017, I founded Sierakowski Classic Car Advisors with a focus on acting as a trusted advisor and agent to collectors. Our services include forming collection acquisition, maintenance and display strategies; advising various aspects of automobile restoration; facilitating acquisition and sale via private treaty and public auction; conducting historical research and building documentation files; and performing appraisals. I am qualified to produce appraisals for the purpose of contemplated sale, insurance, loan collateralization, and matters involving legal proceedings.

I have engaged in professional development via an intensive two-week school comprised of four separate classes pertaining to the appraisal of Personal Vehicle. I have also been trained in the Uniform Standards of Professional Appraisal Practice (USPAP) and have successfully completed testing on the latest standards.
