Arturo Ruiz, DVM, MSC was born and raised in Mexico. He attended De La Salle University in Leon, Guanajuato Mexico from 1980 to 1985 where he earned his Doctor in Veterinary Medicine degree. Several years later he attended National Autonomous University of Mexico in Mexico City, Mexico from 1994 to 1995 and became a Diplomat in Bovine Animal Production. Wanting to continue his education, he relocated to Guelph, Ontario Canada. In 2001 he enrolled in English as a Second Language class at Conestoga College in Kitchener, Ontario. At the same time he started in the Department of Population College at the Ontario Veterinary College in Guelph, Ontario Canada. In 2006 he earned a Master of Science degree.

Arturo has gained work experience from a variety of places to help prepare him for a career in the dairy and swine industries. From 1994 to 1996, he provided technical training of dairy producers on artificial insemination. Then from 1997 to 2000, he worked as an independent dairy health management practitioner attending farms in Leon, Silao and San Francisco de Rincon, La Barca Mexico. Once he relocated to Canada, he worked as a breeding supervisor in Alliston, Ontario Canada and then as a research assistant in bovine reproduction at the University of Guelph from 2000 to 2003. It was in 2003 that he worked as a graduate research assistant in sow reproduction and later worked as a breeding supervisor in sow reproductive programs in Guelph, Ontario Canada. In 2007 he moved to the U.S. and worked as a training and breeding supervisor in gilts for Iowa Select Farms until joining Circle H Headquarters LLC in 2009.

Arturo lives in Dalhart, TX while his family still resides in Guelph, Ontario Canada. He enjoys jogging and spending time with his German Shepherd, Tuck.
