MARVIN SIEGEL’s Experience

Founder & President
Premier Professionals International, LLC

1991 — Present
Marvin laid the foundation for the consultation arm of his practice with the formation of this company. He marketed and delivered consulting services, including serving as an arbitrator in legal disputes, on behalf of a broad range of clients.

PREMIER PROFESSIONALS INTERNATIONAL, LLC is a Chicago, Illinois-based, arbitrator-certified professional services consulting firm that has aligned with many other resources and affiliates in the financial and operational arenas. The consultancy was established in response to the economic concerns of progressive firms who are reluctant to incur the costs of a full-time executive, and wish to derive value from a comprehensive suite of services on a discrete, as-needed basis, or according to project demands.

On an assignment basis, companies wishing to leverage Marvin Siegel’s extensive C-Suite experience, analytical skills, and business acumen will be well-served on all organizational levels.
