Oklahoma Women in Agriculture and Small Business Conference @ Moore Norman Technology Center
Aug 4 – Aug 5 all-day
Oklahoma Women in Agriculture and Small Business Conference @ Moore Norman Technology Center | Oklahoma City | Oklahoma | United States

The 2016 Statewide Women in Agriculture and Small Business Conference will be held on August 4-5, 2016 at the Moore Norman Technology Center on South Penn Avenue in Oklahoma City, OK.

The 2016 keynote speakers are:
Dr. Temple Grandin: professor of livestock behavior and welfare at Colorado State University. Well known for her groundbreaking work in both animal welfare and autism research, Dr. Grandin will share her expertise on livestock handling and facility design to reduce stress in livestock, as well as why it is important for those in the agricultural industry to share their story and be transparent about the work they do.
Kim Bremmer: creator of “Ag Inspirations: Sharing the real story of agriculture”, Kim has been a dairy nutritionist for 15 years and a vocal champion of agriculture everywhere she goes. Her true passion is sharing the REAL story of agriculture with everyday consumers. Dynamic, knowledgeable and enthusiastic, Kim compels audiences to reconsider what they think they already know. Kim is the Wisconsin state coordinator for Common Ground, a national movement of farm women who share information about farming and the food we grow.
Michelle Miller: self-proclaimed “Farm Babe”, Michelle grew up involved in 4-H, horseback riding and doing chores on her friend’s farms, but when her high-school aptitude tests told her to go into farming, she ignored them and headed west for college and a career in fashion. Her life went full circle going from “Rodeo Drive” in Beverly Hills to the rodeo when she met her “Prince Farming” years later. She has since moved to a farm in Iowa where she has learned the truths of modern agriculture firsthand and enjoys educating the public and debunking popular myths she once believed in. Together, they farm nearly 2,000 acres of soybeans, corn, alfalfa, oats, sheep and cattle.

Registration costs $50 by August 1; $60 after. Register online at  For questions contact Sara Siems at or by calling 405-744-9826.
