Dr. Roger Bagg

"Being a veterinarian is the best job in the world! Helping pets through illness and accidents is what it's all about... and keeping them healthy. People who have pets are a class above the rest- great to talk to and listen to what's important to them. Locating in Colorado near the mountains adds to the excitement of living. I like to say there's two seasons to the year, "ski" season and "off" season. But  "off" season can easily be filled with camping, hiking, fishing and motorcycle trips!"
