The Team Behind the Talent 

Nancy Tamayo

Nancy Tamayo

Chief Executive Officer


My role model is Oprah Winfrey.

My favorite thing to watch is Top Gun (I feel the need, the need for speed).

If I wasn't a talent manager, I would be a spy.

My favorite place in the world is Italy (I love to mix history, great food and wonderful people).

When I grew up I wanted to work for Elle Magazine (I achieved that goal and it was overrated).

Now that I am grown up, I want to be happily retired before I am a senior citizen.

I cannot live without my family (including my four legged members).

I live by the words “Do what you love and love what you do.”
