We serve our clients from our US offices in Chicago, Detroit, New York, Tucson, and Richmond, and our Europe offices in Bordeaux and Brussels. In addition, we travel frequently to Europe to meet with our clients and prospects.

Our services are centered around the needs of our clients, and focused on accounting, tax, audit, human ressources, and due diligence.

Most of our personnel are bicultural to ensure efficient and effective communication with clients either in the United States or in their home countries.

All attest and transaction services including audit, limited review, due diligence, and acquisition structuring are performed by International Attest Solutions, a Certified Public Accountant firm. IMS is not a CPA firm.  Both firms work in close cooperation to service the needs of our clients.
