We are a 501 (c) 3 non-profit educational charity.  We welcome your donations of time or money.   Many companies will match your donation.  Please let us know if you work for such a company and we will work with you to help your donation dollars go further!

What’s in a Name?

We are Tierra del Sol Institute.  There is a school with a similar name in California, so please type in the whole name.

Bona Fides & Matching

We are listed with Guidestar, a group that tracks non-profits, and we would share the link but they are not a user friendly site. TDSI is also listed with Network for Good and United Way.

We do know that three corporations will match your donations – Freeport McMoran, Johnson Controls Foundation, and Raytheon.

Amazon Smile.  If you shop with Amazon, please sign up for a “Smile” account and list us as your charity.  They will give us a tiny percentage of every purchase you make at no additional cost to you.

Giving Tuesday

We will be  raising funds through Facebook on Giving Tuesday – the Tuesday after Thanksgiving.  Please watch our Facebook page for more details.

Donate – Sorry Not Here

Last time we linked our website to a donation site we got hacked and destroyed.  Mean people suck!

Thank you!
