Where we had one person and a contractor, we now have 5 people and a contractor. Jonathan joined the Colorado Weed Management Association in 1991 and has been an active member ever since. Worked on the Applicator School Committee since that time. He has also served on the education committee and the annual conference committee. Was a board member for 4 years and served as vice president 2years. Most recently serving as the President of the association in 2010. Jonathan has been on the North American Weed Management Association board of directors and served as sec/treas. Participated in the Western Society of Weed Science. Jonathan grew up on the family farm in central Kansas. Often came to Colorado for a family vacation. Fought bindweed, and puncturevine as a boy. The first initiation into noxious weeds came in 4H in a crop and weed ID contest. I was in the KS noxious weed program from 1981 to 1991 in 3 different counties. He attended Kansas State receiving a bachelor’s degree in Agronomy in 1980.

Prior to starting Grassland Nutrition Consulting, Kelcey worked in the Nutrition/Feeds and Feeding industry for 18 years. In addition to multiple internship experiences and part-time positions during her education, she worked for three very reputable nutrition/feed companies. First, she worked for Cargill Animal Nutrition’s Nutrena and Acco brand feed divisions in Ft. Worth, Texas, and eventually became a Territory Manager for them in the Rocky Mountain Region. Then, she got the opportunity to learn about carnivore diets and was the District Manager for the pet food company, Royal Canin, along with the Eastern shore board. Lastly, while completing her doctorate at CSU, Kelcey had the great opportunity to return to Ranch-Way Feeds as their head nutritionist (where she had once been an intern). While there, her primary role was to provide technical nutrition and formulation services to their diverse customer base and develop a HACCP program. Currently, Kelcey is also an Affiliate Faculty Member at CSU and is honored to have the opportunity to guest-lecture in their Animal Science and Equine Science classes, advise grad students, and be privy to their ongoing research efforts.

John’s office is in Broomfield but works in the field in the summer all over eastern Colorado. He is the project lead for EAB, Japanese beetle, leafy spurge, diffuse and spotted knapweed biocontrol. He oversees technicians whose work includes studying, collecting and redistributing agents for Canada thistle, field bindweed, puncturevine, Dalmatian and yellow toadflax and musk thistle.

Ms. Clark received her Ph.D. in Weed Science from Colorado State University.
