Meet Our Staff Veterinarians

Organic Valley farmer members have access to two veterinarians on our cooperative's staff.

Dr. Paul Dettloff

B.S. University of Minnesota
D.V.M. University of Minnesota

Dr. Paul Dettloff has worked with CROPP Cooperative to ensure healthy livestock since 2002. His Arcadia, Wis., large-animal practice has become the home base of an internationally recognized organic herd health expert.

In 1988, after 20 years serving conventional farmers, “Doc” Dettloff’s observations led to his interest in organic methods. Since then, Dettloff has dedicated himself to sustainable and organic/biological treatment for dairy and beef cattle, sheep and goats. He has researched and developed treatment protocols for many natural remedies, botanicals and homeopathic medicines.

At CROPP Cooperative, Dettloff consults with more than 1,000 member farmers across the United States in person and over the phone. He also trains field personnel, attends regional educational meetings and conducts a yearly hands-on veterinary workshop to educate farmers and conventional veterinarians on organic livestock care practices. He emphasizes healthy soil as the foundation for healthy animals and advises not giving animals anything people wouldn’t give themselves.

Dettloff is committed to sharing his vast array of knowledge with others. He parlayed the tinctures and botanicals he developed into Dr. Paul’s Lab brand herd health products and co-founded Crystal Creek, a natural veterinary supply and remedy provider. Dettloff is also a consultant for Lancaster Ag Products in Ronks, Pa., and Essential Water Solution in Story City, Iowa. He authored Alternative Treatments for Ruminant Animals and has written several CROPP Cooperative Organic Farming Technical Bulletins, covering topics from stray currents to natural mastitis treatments.

Dr. Guy Jodarski

B.S. Biology, University of Wisconsin-River Falls
D.V.M. University of Wisconsin-Madison

Dr. Jodarski has worked with CROPP Cooperative to maintain and improve animal health on our 1,300 member farms since 2007. Belief that organics was a more sustainable way to run a farm led him to the field.

In practice since 1987, Dr. Jodarski was an owner/partner in a central Wisconsin large animal practice for 12 years. He then was a consultant for an international cattle breeding company and later worked as a staff veterinarian for two companies that supply nutritional supplements and livestock health aids for organic and sustainable farmers.

At CROPP Cooperative, Dr. Jodarski focuses on organic and sustainable livestock practices. In addition to consulting with CROPP Cooperative livestock farmers across the United States, Jodarski trains field personnel, attends regional educational meetings and gives presentations on how to keep food animals healthy without the use of antibiotics, synthetic hormones and chemicals.

Dr. Jodarksi recently co-authored his first CROPP Cooperative Organic Farming Technical Bulletin, and is a regular contributor to the cooperative’s member newsletter, The CROPP Forum, on herd health matters.
