Educational session at the DoubleTree

Jonathan Wallace
Basketball Operations Associate
Denver Nuggets

Speaker Topic: The Millennial Rancher: Progression in the midst of cultural change.

Jonathan Wallace grew up on the family farm in Harvest, Alabama, where he was introduced to skills that would set the foundation for his career.


Wallace accepted an offer to attend Princeton University until his path was rerouted to follow Coach John Thompson III to Georgetown University as a walk-on for the men’s basketball team. Wallace earned a full scholarship by the third game of his freshman year and started every game of his career, was part of four teams that went to the postseason (including three straight NCAA Tournament appearances), won back-to-back Big East Regular Season titles, and a Big East Tournament Championship. He set the record for 3-point makes and ranks third all-time in career starts at Georgetown.


Following his graduation, Wallace embarked on a professional career that took him from the NBA Developmental League to Slovenia, Germany, Belgium, and Africa. When Wallace returned to Georgetown, he served as special assistant to the head coach for both John Thompson III and Patrick Ewing. In 2019, he completed the executive master’s in leadership program through Gerogetown’s McDonough School of Business. He is currently in his second year as operations associate for the Denver Nuggets, where his focus involves player development, NBA draft prep, in-season trades, and organizational management.


Wallace also runs Capshaw Ridge Cattle Company, a cow-calf beef cattle operation using SimGenetics in Harvest, Alabama.


Tim Holt, DVM
Professor and Clinical Instructor
Colorado State University

Speaker Topic:  Understanding Pulmonary Hypertension in Cattle in the Context of Arterial Pressures (PAP), Brisket Disease, and Late Term Feedlot Death.

Dr. Tim Holt graduated Veterinary School in 1988 from Colorado State University. Directly after graduating, he joined a mixed animal practice in the rural mountains of Colorado at 8,000 feet elevation in the town of Gunnison. Dr. Holt remained in this practice for the next 18 years treating any animal that came through the door. Since 1980, Dr. Holt has been measuring pulmonary arterial pressures (PAP) in the western US, and has traveled abroad doing research in the area of bovine high mountain disease and pulmonary hypertension. He has now carried out over 462,000 PAP measurements and continues to utilize this tool in evaluating the heritability of pulmonary hypertension in cattle assisting in sire selection and the development of resistant herds. In 2005, Dr. Holt moved from Gunnison to Fort Collins and joined the faculty at Colorado State University’s Veterinary Teaching Hospital. Currently, he teaches at CSU’s College of Veterinary Medicine  in the Livestock Medicine and Surgery Department where he incorporates the taking of PAP measurements into his teaching. Dr. Holt, in collaboration with others, continues to explore and research the many mysteries of pulmonary hypertension in cattle. One of Dr. Holt's most recent endeavors is studying and evaluating the increase in feedlot cardiac death, and potential tie between bovine high mountain disease and acute cardiac failure.

Milt Thomas, PhD

Mark Enns, PhD
Colorado State University

Speaker Topic:  PAP EPD Development and Appropriate Use.

Mark Enns grew up working on the family’s fourth- generation wheat and cattle operation in northwest Oklahoma. Those early experiences stimulated his interest in livestock and agriculture and led him to undergraduate degrees from Tabor College, and masters and doctorate degrees in animal breeding and genetics from Colorado State University (CSU). After completing his education, he worked two years in New Zealand for Landcorp Farming Ltd, the largest ranching company in the country. At Landcorp, he developed genetic improvement programs for beef cattle, deer, sheep, and goats. After his time in New Zealand, he spent four years at the University of Arizona and then joined the Department of Animal Sciences at CSU in 2001. As a professor at CSU he teaches courses at both the undergraduate and graduate level in animal breeding and genetics, and in livestock production systems; and serves as the director of the Western Center for Integrated Resource Management. His primary research focus is on beef cow adaptability/longevity and genetic improvement in susceptibility to bovine respiratory disease and pulmonary hypertension (e.g. high mountain disease and feedlot heart failure). He has special interest in using multi-trait selection and genetic improvement to better profitability of beef production.


Dr. Enns serves the beef industry through activities with the CSU Center for Genetic Evaluation of Livestock — a center that calculates EPD and performs foundational genetic evaluation research for breed associations and producer groups both nationally and internationally. In addition, he serves on the board of directors for the Beef Improvement Federation as the western region secretary.

Randie Culbertson, PhD
Lead Geneticist

Speaker Topic:  Feed Intake vs Feed Efficiency: What should we be selecting for?


Randie Culbertson is a graduate of Colorado State University, where she earned her MS and PhD in animal breeding and genetics. She accepted the position as lead geneticist for International Genetic Solutions (IGS), in November 2019.
Dr. Culbertson spent her childhood on the family’s cattle ranch in northern New Mexico. She later attended New Mexico State University where she obtained a BS in animal science. Her master’s research project examined the effect of the genetic potential for beef cattle milk production and the ability to remain in production with improved longevity (or stayability). In conjunction with her research, Dr. Culbertson was placed in charge of coordinating test schedules and data collection for CSU’s Feed Intake Unit. This work led to her interest in feed intake as a trait. As a result, her doctoral research focused on feed intake in beef cattle and specifically the implementation for genetic improvement.
In addition to her graduate work, Dr. Culbertson conducted several genetic evaluations for new and novel traits for breed associations and cattle producers. Some of the traits she worked on included heifer pregnancy, stayability, and a multi-trait analysis of pulmonary arterial pressure (PAP). The last nine months at CSU, Dr. Culbertson managed and coordinated a USDA grant project examining late feedlot death in cattle. This project studied the effects of PAP on the performance and survivability of fed steers and began to answer some questions about this growing concern.
