“Their service and expertise continues to exceed expectation. Joanna and Sarah are an invaluable asset to those they serve, and a pleasure to work with. If you are in need of real, valuable, professional insight into your soil’s needs, DBS is the clear choice.”
~ Michael Beck, Sales Manager – Royal Gold

Sarah Schuette: Certified Professional Soil Scientist/ Co-Owner

Meet Sarah, Certified Professional Soil Scientist and Co-Owner of DBS. She hails from Saint Paul, Minnesota and is one of thirteen. Sarah graduated from Humboldt State with a degree in Soil Science (minoring in Botany & GIS). This mathematician and chemist is dedicated to helping farmers grow healthy, sustainable crops and uses her skills in her own garden. When she’s not working in the lab or gardening, Sarah may be found making clean cannabis medicine, twirling in aerial silks, or hula hooping. She has a hidden talent of wiggling her ears (shh, don’t tell). “Soil and water are the foundation of life on this planet, without which none of us would be here.”

 Joanna Berg: Certified Professional Soil Scientist/ Co-Owner

Meet Joanna, Certified Professional Soil Scientist and Co-Owner of DBS. Joanna is from Minneapolis, Minnesota and graduated from Humboldt State with a degree in Soil Science (minor in Watershed Management). Her passion to improve access to scientific and professional agriculture in the cannabis industry comes from years of working in the business. When she’s not hanging with her most adorable little boy, or walking her dog, Joanna may be jamming some West African percussion. Few know she plays some mean spoons (no joke). “Soil is life – know soil, know life. No soil, no life.”


Lauren Quackenbush: Soil Consultant & Certified Pest Control Advisor

Meet Lauren, our Soil Consultant and Certified Pest Control Advisor. She is a Humboldt State graduate with a degree in Soil Science.

Steve Chowdhury: Lab Technician

Meet Steve, our Lab Technician. He is a Fairbanks,  Alaska native. Steve moved to warmer climates to get his degree in Chemistry from UCSB. He’s fascinated by science –  drug synthesis and biochemistry are his jam. When he’s not jamming in the lab, Steve can be seen & heard killing it on the guitar. He also sings, plays the bass, the violin and is passionate about classical guitar. “Nothing makes me happier than the fact that I can pursue chemistry and play music at the same time.”  

Lauren Smith: Lab Technician/Quality Control

She and her wife have  a dog, 2 cats and 1 snake. “Soil reminds me of two things I love: science and my garden.”

Zoe Merrill: Consulting Associate
