TJ Warfield   FOUNDER  [SHE/HER]

My passion is to empower nonprofit staff to better meet their organizations' missions by providing solid systems, allowing staff to focus their energies on what matters instead of spinning their wheels on data and technology.

I hold a M.S. in Computer Information Systems with over 10 years of experience with Salesforce, over 20 years of experience with Information Technologies, and over 25 years working with nonprofits.


With a previous background in Marine Biology, I have served as a docent for Friends of the Elephant Seal and a volunteer researcher for both Bimini Biological Field Station and NOAA/Scripps. As a certified SCUBA diver since high school, I remain obsessed about shark diving and am an avid hiker, who is proud to call the Bay Area home. I know about living your passion, just like my clients.


However, above all else, I am Mommy to the most adorable, compassionate, and loving eight-year-old kiddo.
