Susan Carpenter Noble spent much of her career, training horses, coaching riding students, teaching horsemanship clinics, and freelancing for national horse magazines (The Reiner, et al.)  During her professional years – and, even now, when coaching riders remains a favorite hobby – her students and/or horses have earned State and Regional Championhips in:

·         Western Reining

·         Western Riding

·         Trail

·         Western Horsemanship

·         Hunter Hack

·         Hunter

·         Jumper

·         Dressage

·         Barrel Racing

She has also coached six young women to become State HS Rodeo Queens, and one National Rodeo Queen, and helped coach another who went on to finish Top Ten in Women’s Professional Barrel Racing.

About ten years ago, a 12-year-old riding student complained to her that he had quit reading, because “No one writes for ranch kids.”  She promptly took up the challenge.  Her first two books, Cowgirls Don’t Quit and The Free Horse, which are both set in Montezuma County, were published in 2020.  The third book in the series, Half a Saddle Off, was published in 2022, and moves the story to Nevada.

Noble, a seventeen year resident of Lewis, CO, is proud to be a part of the 41st annual Four Corners Ag Expo and its efforts in promoting both the traditions and the advancements in the Farm and Ranch lifestyle.

Dr. Petra grew up in Austria surrounded by horses. She started riding at age 4 when her father bought her a very opinionated Shetland pony mare named Sheriff.

After seven years as an equine sports massage therapist, Dr. Petra shifted her focus to animal chiropractic once she observed the power of an adjustment and how quickly horses responded to it.  Petra received her Animal Chiropractic Certification through Options for Animals in Wellsville, Kansas in 2008 and is certified by the International Veterinary Chiropractic Association AND the American Veterinary Chiropractic Association.

Animal Chiropractic has given Dr. Petra the opportunity to use her extensive chiropractic knowledge while working with her passion. Her work has taken her to beautiful locations, meeting exceptional horsemen and horsewomen such as Mark Rashid & Crissi McDonald & Major Miguel Tavora (Master of Equitation and protégé of Nuno Oliviera)

She currently resides in Mancos, Colorado with her husband Dr. Clayton Sullwold, several horses and many other critters. Besides adjusting horses, Dr. Petra loves to teach. 2 years ago, she started an Animal Chiropractic School where certified animal chiropractors and veterinarians can gain additional knowledge and continuing education credits in the field of animal chiropractic. She is beyond thrilled about the growth and success of the school as she gets to not only teach in beautiful Mancos, but also in Austria, France and Chile.

and handling classes. The class will describe the handling, preparation, and storage of
food in ways that prevent food borne illnesses. This includes a number of routines that

2. Separate raw and cooked foods to prevent contaminating the cooked foods.
