Doctor Whittle, known affectionately around here as "Doc", did his pre-vet studies at the University of Kentucky. He then went on to study veterinary science at Auburn University, graduating in 1987. Upon receiving his doctorate, he moved to Wilmington, North Carolina where he practiced for two years. In 1989 moved to the Chicagoland area to work for Dr. Reece at Palos Animal Hospital..

Two years later, Mill Creek Animal Clinic was opened in Palos Park. Although Mill Creek was associated with Palos Animal Hospital until 1997, it has long been an independent practice.  

On a personal note, Dr. Whittle lives in Homer Glen with his wife Jane, beautiful daughters Olivia and Cecilia, son Dolan , and their dog Ricky Ricardo.
