Our difference

At MGI we dedicate special attention to each and every client. Throughout the world, we believe that strong professional relationships and trust are built only on the basis of respect, clear communications and attention to the commitments assumed.

MGI Worldwide member firms are led by their partners. We know the day-to-day activities of our clients, their challenges and their goals. We know what it means to be an entrepreneur and we understand their business, not just their accounts.

MGI Worldwide is present on every continent and in every world-class economic hub. We have member firms in more than 85 countries, and we have been experiencing continuous growth. Whatever the level of complexity of our clients’ needs, we have in our network the experience and knowledge to help them.

Our quality

If your Company targets the challenging middle market, you know that success depends on defining your potential customer and modelling your products and services to meet their needs.

We at MGI organize to meet the needs created by the international expansion of middle-market companies. Our worldwide members are experienced business advisors in their countries. They lead their practices personally and are the main contact persons for their clients. Foremost, they value their international MGI membership and welcome the liaison of the clients’ international service partners.

The focus on personal attention is the hallmark of our client service strategy. The staff on the team serving our clients are important resources, but close supervision and scrutiny by our partners are the key to our standards of quality. This includes clear and outright communications, prompt responses and respect to commitments. These values make up the defining criteria for differentiating our services.

And, if you are strict about uniform levels of quality in your service providers, be certain that we do, too. Our permanent quality review program assures that each of our member firms is independently and periodically assessed with regard to ethical and professional practices.

At MGI we are personal, we talk business, and we act global.
