We've been bringing our 2 golden retriever's & maltese to Dr. Marcum for 10 yrs off & on (lived in Vegas a while). Upon moving back we were happy to find he has a very nice, brand spanking new building in the same spot on Preston Rd. in Frisco. Recently our golden retriever 'Whiskey' swallowed a sock & required emergency surgery to remove it from his intestines. He was very sick & had to stay there for 3 days. Dr. Marcum was extremely knowledgeable and thorough explaining to us what happened. You can tell he is in this business for his love & dedication to animals. Whiskey recovered fully & I'm so thankful to Dr. Marcum & his staff for saving our furry baby. They took wonderful care of him. I wouldn't trust my dogs to anyone else.
