Donate to HSEF

As a Non profit 501(C)(3) public charity donations from the public are our life-line and we have very few to date.

Tax ID 45-1800245 - 100% tax deductable donations

HSEF needs a company or business to become our title sponsor! 2 years without a Title Sponsor has been very difficult.

Picture YOUR COMPANY NAME HERE followed by HSEF on every email, flyer, award ribbon, press release...etc. 

HSEF is an eligible organization for Corporate Matching! Fill out the form below so we can reach out about how to donate to our fair!

Become a Patron Donor

The IRS requires 501(C)(3) public charity nonprofit organizations to receive 1/3 of their funding from the public at large. We are short of that this year. Every $25 or more donation helps.

Tax ID 45-1800245

THANK YOU TO OUR ACSEF 2025 SPONSORS!
