Dr. Margot's Bio

Having always loved animals, Dr. Margot detoured into a starting career in public relations/journalism before returning to school to study veterinary medicine. However, that communications background has always helped in her veterinary work in educating owners on the best care for their pets. After graduating from the veterinary school at Colorado State University in 2000, she completed a 13-month small animal internship at Friendship Hospital for Animals in Washington, DC. Dr. Margot returned to Colorado in 2004. A lifetime goal of opening her own veterinary practice was met when Park Hill Veterinary Medical Center opened in July 2011. Dr. Margot’s medical interests include Wellness/Preventive Medicine, Dentistry, Nutrition, Marketing and Client Education. The practice has grown and flourished since opening with the support of our great neighborhood and community. Dr. Margot is married to Chris, our hospital manager. They have two active and lovely daughters, Savannah and Caitlin; two cats and three dogs. When there is any spare time, you might find Dr. Margot with her nose in a book, behind the camera or digitally scrapbooking.
