At the Northern California Community Blood Bank our purpose is centered on helping others, and we are incredibly proud of two team members who carry that dedication far beyond our walls.
When they’re not serving our community through the work, they do here at the blood bank, our CEO, Kate Witthaus, and Charlotte Castro, from our Donor Services team, devote their time and hearts to another important cause, volunteering with Humboldt SAR.
Their commitment to helping others, whether through ensuring blood is available for patients in need or answering the call during emergencies and rescues, is truly inspiring. They represent the compassion, courage, and selflessness that make Humboldt County stronger every day.
Thank you, Kate and Charlotte, for all you do to serve and protect others both inside and outside the blood bank. We are so proud to have you on our team.
