I was not happy with the last two vets that I tried in Boulder, but have had really good experiences with both Dr.'s Russell and Fuller.
Dr. Russell was very compassionate when he both met and euthanized my cat, Bob, in a span of 5 days in early January. Losing my 9 year old cat to renal failure so suddenly was obviously a terrible experience but Dr. Russell did everything from quieting his booming voice to library standards (Bob was scared of men and loud noises) to over-explaining the situation and procedures. He made a terrible situation a little better.
Dr. Fuller was very personable and patient as he went over my dog's teeth cleaning and tooth extraction at the beginning of February. He not only kept the extracted tooth for me to see, but showed me pictures before and after extraction. Basically, he treated me like my dog was my child and the staff treated my dog like they had never seen something so cute.
