Our team goes for the "no stone left unturned" fundraising philosophy.
Outside of our main and very generous sponsor, Harris, we have a major patron drive (which is not mailing out letters but visiting businesses in person - an important factor to its continued success), as well as smaller fundraisers such as car washes, Uno Pizza nights, Applebee's Pancake Breakfasts, and many more.
Our patron drive raises between $8000 to $18,000 a year, as well as provides us about 200 contacts in the community which gives us a good fan base for support at events, and a continual source of new places to demonstrate the robot and talk about FIRST. Most if not all of the details are on our website.
