National Psoriasis Foundation bike ride
Top Fund Raisers!

To our community:

Thank you for supporting our National Psoriasis Foundation bike ride and helping us to fund psoriasis and psoriatic arthritis research and education. A day in Napa is almost always a good day, but this was an exceptional day. We joined patients, physician colleagues, pharmaceutical companies and NPF advocates. We rode 60 miles through aromatic wineries and picturesque hills and we were the top fund raisers!

The feeling of community was overwhelming – and this was a huge success for NPF. Thank you for supporting us with your words and donations and helping us contribute to this amazing organization.

-Dr. Homa and Dr. Krasnoff
