If you re thinking about contributing to FOGL 501(c)(3) projects, now’s the time! 

Recently a number of our loyal friends have contacted us saying mail they had sent us, including announcements, personal updates, and even donations, has been returned to them when they used the same postal address they have used for years.

IT’S TRUE!  We have a new postal address with a new Zip Code, replacing the old one..

The new address is Friends of Green Lake, PO Box 31905, Seattle, Washington 98103.

We have also stopped using Venmo at this time, so ij’s even more important to use the new PO Box if you are making a donation!. For how to make a tax-free donation to Friends of Green Lake click on the menu item Helping above.
