Word from Isabel Marcus Columbus

Founder and President

I founded the company on the principle of creating a new type of business services hub, one with a personal and tailored approach to each client’s project. Being a native of France, where I used to work in the Entertainment industry, I perfectly understand the challenge it represents for foreigners to work and reside in the United States. As such, I aim to welcome every client in a nurtured way, guiding him or her through the subtle and intense path of the expatriation and relocation in the United States.

With enthusiasm, in-depth knowledge of business practices and extensive experience dealing with multinational companies and entrepreneurs’ business needs, I’m fully determined to find solutions, even a creative one! I’m proud to lead a company where I, my distinguished team as well as our network of experts and partners humbly contribute to the professional and personal endeavors and successes of our clients in the US.
