Meet Our Embajadores – The Heart of the Chamber

Our Embajadores, Spanish for Ambassadors are an indispensable part of the Green Valley Sahuarita Chamber of Commerce and Visitor Center.

These dedicated volunteers are often the first friendly faces you’ll see when you walk through our doors or the helpful voice on the other end of the phone.

They assist visitors, support Chamber and community events, and offer a wealth of knowledge about Green Valley, Sahuarita, and the surrounding Southern Arizona region.

Many have volunteered with us for years. Some for over 15 and their passion for the community shines through in every interaction.

We invite you to stop by, say hello, and get to know the people who help make our Chamber such a welcoming place.
