Dr. Karen Anderson


  • ""My dogs, Pup Pup and Sugar recently had a 4 day stay here. How lucky were they to have such devoted care with the entire vet staff and in the kennel. Dr. Anderson is fabulous and is on site 24 hours?! That is an added bonus (especially if you're like me and worry about your dogs). Both needed meds and were carefully attended to. I was able to enjoy my stay in Vermont knowing they were being looked after with such devotion. I would love to have a vet like Dr. Anderson in D.C. She is thorough and knowledgeable and caring. Larissa was especially kind to my dogs and showed them extra special love. Thank you all, a million times over, for doing such a fantastic job. There was another staff member from Indiana whose name escapes me who was lovely as well as vet student (Josh?). All were wonderful, kind people. Rest assured that your dog will be in great care if you go to Mad River Veterinary Service and kennels!!!! I'd give them 10 stars if I could!""

  • ""I was heart broken with a sick dog I hadn’t seen in a year and on my way (literally in between states) to see my dear friend. I need to see a vet. I needed someone to care about me and my dog. Dr. K did that and so much more. I can’t tell you how grateful I am for the time and patience she took with us-a same day appt even! She was gentle, no nonsense, thorough and understanding. We left with a plan and both Murphy and I got a great night sleep. Today, Murphy is in the road to recovery and if I could I would bring him back to see her every year. (We live in MN).""

  • "Today our dog ran into our garden fence after slipping on the ice. He had a huge seven inch gash. Karen gave up her afternoon of skiing to take care of our family. She was amazing! He is sleeping now on the couch back at home. We love how much Karen takes care of our family!!
