Dr Brim was born and raised on a family farm in central Iowa where she was avidly involved in 4-H, showing Holstein Dairy cattle, chickens, and Arabian Horses. She grew up raising and caring for a variety of farm animals, cat, dogs and the occasional wild animal. When she was not busy doing chores or riding horses she was busy helping her family raise and preserve the bulk of their food.

Dr Brim earned her B.S. in Genetics in 1987, becoming the first woman to graduate from Iowa State University in this degree program. During her Undergraduate years, Dr Brim worked in the Genetics Laboratory on campus and Iowa State University Dairy Farm milking cows. She worked for one year post graduation as a Genetics Engineer prior to pursuing her passion in Veterinary Medicine.
