Growing up in Oklahoma City, Dr. Robertson enrolled at Oklahoma State University as a Physiology major and Chemistry minor. After earning his undergraduate degree in 1982, he spent the next four years working toward his doctorate in veterinary medicine. He was a member of Phi Zeta and Phi Kappa Phi Honor Society and he received a scholarship for his leadership, scholarship, and clinical proficiency.

Before becoming a veterinarian, Dr. Robertson volunteered on a dairy farm and with his veterinarian uncle. He worked for more than ten years as an associate veterinarian before opening Cobblestone Veterinary Hospital with his wife Christine in Spring 1997. Dr. Robertson is a member of the American Association of Feline Practitioners and Missouri Veterinary Medical Association. His professional veterinary interests include feline medicine and preventative care. The most satisfying part of being a veterinarian, he says, is watching sick or injured animals recover and being a part of their lives.

Dr. Robertson and his wife share their home with two dogs (Cooper and Blue), five cats (Ming Ming, Squatter, Night, Winslow, and Otter) and horses. Together, the couple has two daughters. In his free time, Dr. Robertson enjoys hiking, boating, snorkeling, and traveling.
