JOHN D. BORZILLO, DVM.

C.O.O

Dr. John Borzillo was born and raised in Hermann, Missouri, a small agricultural community an hour West of St. Louis, Missouri, USA. In 2009, John graduated from The University of Missouri-Columbia as a Doctor of Veterinary Medicine and immediately moved to Wisconsin, USA – “America’s Dairyland”.

During his time at the University of Missouri, he focused primarily on herd-level medicine and management. These interests allowed him to travel the U.S. and participate in multiple, dairy-specific internships and certificate programs, including Summer Dairy Institute at Cornell University.

In 2014 John partnered with Cody Heller to form Central Wisconsin Ag Services, LLC (CWAS) where he currently serves the dairy farms of Clark, Jackson and Wood counties, Wisconsin. However, the partnership has developed into a multi-faceted agricultural consulting firm offering subject matter expertise in agronomy and biogas project management.

His professional interests at home and abroad include herd health, medicine and surgery, bovine reproductive performance, preventative health and biosecurity, training of on-farm staff, residue compliance, establishment of Key Performance Indicators (KPI) and outcome-based management strategies as well as anaerobic manure management and regenerative agriculture.

DAVE HAMMAN, DVM

Veterinarian

Dr. David Hamman grew up on a farm in Carthage, Illinois where he became interested in veterinary medicine after the local vet performed necropsies on two of his older brother’s fair steers (the older brother was less impressed...). This interest led down a winding path that included behavior and nutrition research at a zoo, wildlife toxicology in Michigan, and beef cattle in Tanzania before working with dairy cattle in veterinary school at Michigan State University.

In school Dave developed a strong interest in milk quality and mastitis management, and has pursued this interest continuously since graduating and moving to Wisconsin. He gets a great deal of satisfaction from helping dairy producers identify opportunities for growth and improved efficiency while improving the lives of their cattle at the same time.

Dave currently lives with his wife Mary and two sons Zach and Nate in rural Blair, Wisconsin. They enjoy a lot of the outdoor activities that Wisconsin has to offer, as well as domestic and international travel.

ANDREW MARTIN, DVM

Veterinarian

Dr. Andrew “Marty” Martin was born and raised in the suburbs of Chicago, but don’t hold that against him. His initial exposure to animal agriculture was as an undergrad while pursuing an animal science degree at the University of Illinois. He enjoyed it so much, that he continued his veterinary training in production medicine.

While in veterinary school, Andrew traveled both nationally and internationally to gauge the dairy industry. This included traveling to dairies in Idaho, Washington, Indiana, British Columbia, Italy, Switzerland, Honduras, Mongolia and of course Wisconsin. He is very excited to incorporate the concepts he has learned over the past four years to clients in the central Wisconsin area. His professional interests include employee training, animal welfare and bovine medicine/surgery.

Outside of work, Andrew loves to be in the outdoors; hiking, camping, boating and downhill skiing are some of his favorites. He also enjoys traveling to do mission work with Christian Veterinary Missions. His most recent trip was to Mongolia, where he taught, but also learned from the herdsman about parasite control and intensive pasture grazing. Outside of his hobbies and work, his family, church, and friends, keep his life pretty busy.

Overall, he is excited to start a career in central Wisconsin and he looks forward to forming long lasting relationships with the clients in the area.

In 2007, she graduated from the University of Wisconsin – Eau Claire with a Bachelor’s degree in Mathematics and taught high school math for 5 years.

Megan’s love of numbers led her to return to UWEC to obtain her accounting degree. She graduated in 2015 with a Bachelor’s of Business Administration in Accounting.

Veterinarian

Dr. Luke Trapp graduated from Auburn University in 2023 with a Doctorate in Veterinary Medicine. After graduation, Dr. Trapp relocated to Wisconsin to pursue his passion of being a large animal veterinarian. Growing up on a commercial cow-calf operation in Kentucky is what lead to his interest in cattle and genetics. Dr. Trapp performs many procedures and offers a variety of services in advanced reproductive techniques/embryology and beef cattle management aside from being a dairy veterinarian. When he isn’t working he spends as much time as he can outdoors or at a cattle show.
