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!

If you wist to – please reach out to us with this contact form or on the Contact page.  Our staff will contact you and you will be able to donate through Paypal.  Since we are a volunteer organization, please be patient, we will get back to you but it might take some time.

Thank you!
