The DBS Team


Sarah Schuette: Certified Professional Soil Scientist

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

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.”

Consulting Department

Zoe Merrill: Consulting Associate

“Soil reflects the truth that everything is connected.” Meet Zoë, our Consulting Associate. Growing up in Sun Valley, Idaho, she took to riding snow at the age of 3. Zoë graduated from Humboldt State with a degree in Wildland Soil Science and a Master of Business Administration emphasizing Sustainability. Her dream of working with both science and cannabis has come true over the last year working at DBS. Though she misses the snow, Zoë loves the secret micro-climates Humboldt has to offer. Find her outside or follow her @snowzo on Instagram.

Lauren Smith: Lab Technician/Quality Control

Born in Southern California but has migrated to several states. While residing in Missouri, she completed her BS in Biology while minoring in Chemistry at the University of Missouri.

When not in the lab you can find Lauren in the ocean or the garden with her dog, Wave. She also loves to play soccer in the Humboldt Soccer League.
