Arun received his veterinary degree from the University of Minnesota in 1994 and completed a small animal internship the following year at the University of Missouri. After 14 years of working in private practice, he broke out on his own and opened Mountainwood Pet Hospital in Windsor in 2008. This practice filled a niche for clients who wanted down to earth, compassionate, and personalized care for their pets.

Arun has an Aussie doodle, Lola and a goldendoodle, Mac. In Dr. R’s spare time he likes to be social, golf and go skiing with his 2 sons Tage, Rayne and spend time with his Girlfriend Heather.
