One Small Drop is a non-profit association with a vision to:

  • change the world one person at a time
  • educate those with resources to serve those who have needs
  • create a change of perspective
  • change the world through service and education


One Small Drop is founded on the belief of world changers who know just one small drop of water, financial support or volunteer sweat equity can bring a flood of help to the poorest of places in the world.


My name is Tammie Jo Berg. I am the founder of One Small Drop. I’ve been married to my best friend – Brian Derus – for 11 years. I have 3 great kids: Zack 24, Alexandria 22, Paige 19. I have been in the field of Youth and Family Ministry for the past 10 years. I have a passion for global outreach and providing opportunities to reach beyond borders, to grow and learn together, to make the world a better place…one drop at a time.
