Board of Directors


Dave Brock – Founding Director

Dave graduated from the University of Guelph in Animal Science and entered the work force as assistant Ag. Rep. in Middlesex County.  After three years, he began full time farming near Hensall, Ontario.  For several years Dave raised finishing hogs, cash crops and sold Pioneer Seed Corn. In 1997 Dave purchased a corporate breeder farm facilitating an opportunity for his two sons to return to the farm. Twenty years later, much of that quota is housed in newer facilities on the home land base. The pullet component for the breeder business was added in 2006. In 2017, a small broiler operation was purchased. The participation in Trillium Hatchery rounds out the integration of three segments of the chicken meat business. This integration has given a more complete vision of the poultry meat business and the challenges it faces.

Carolyn Cornellisen

Carolyn is an agriculture business owner with her husband George Cornelissen and her children Mike, Danielle and Kyle. Together they own and operate Cornelissen Farms Inc. and Twin Creeks Greenhouse Inc. For over 26 years they have been in the feather industry starting with layers and poultry and then switching to broiler – roaster chickens in 1995. Their business also includes cash crops, operation of a grain elevator, field custom work and greenhouses producing red peppers.

Carolyn’s main job description and specialty is financing. With her background in accounting, she deals with all the day to day operating of Cornelissen Farms Inc. and oversees Twin Creeks Greenhouses.

As a believer in community work, Carolyn has volunteered as Skate Canada Test Chair for the local skating clubs, has been a 4H leader, and has sat on the township recreation committee. Presently, Carolyn is a director for the local agriculture society and part of a committee for community youth leadership programs.

Carolyn believes in working for the betterment of her industry and continuing to gain personal knowledge. To further these goals she is a new District Customer Representative with CFO for District 3 and a Director for Trillium Hatchery. She finds the work in both of these positions to be very rewarding. The opportunity to work with great industry leaders both at CFO and Trillium Hatchery is one Carolyn will work hard to make the most of.

Derek Detzler

Derek, his wife Jacquie, and their three children live on a farm outside of Mildmay Ontario.

For over 10 years, his focus has been on the sustainable reduction of antibiotic use in poultry. The family’s farm currently raises approximately 110,000 birds per cycle without the use of antibiotics.

Derek’s consulted globally for various vaccine / pharmaceutical companies
and was a member of the Chicken farmers of Canada antibiotic reduction committee. He is also a PAACO certified poultry welfare auditor.

He is also the Global Technical Services Manager for Jefo Nutrition. In his role he leads a global team of veterinarians and nutritionists concentrating on the sales and technical service of science based alternatives to antibiotics. These products include organic acids, phytogenics, and enzymes.

Peter Greydanus

Peter grew up on a broiler breeder farm in Lambton County. He graduated with a Diploma in Mechanical Engineering from Sheridan College in 2001. After a brief career in drafting, he decided agriculture was more appealing. In 2002, he purchased his first farm. The Greydanus family farm, located in Petrolia, Ontario, has seen continuous growth ever since.

The poultry operation includes pullet rearing and hatching egg production. Investing in a producer owned and operated hatchery was a logical next step. Peter believes that ultimately the business of agriculture requires the ongoing implementation of new technology. Trillium Hatchery is a company founded on that principal. Peter believes that Trillium Hatchery will establish itself as a leader in the hatching of quality antibiotic free broiler chicks.

When surplus time can be found, Peter, father of three, enjoys flying airplanes and is currently restoring a 1943 Boeing Stearman aircraft.
