Dan Sargent, DVM, Owner

Dr. Sargent has always had a passion for medicine. He was born with a congenital heart defect and spent much of his early childhood in the hospital. His heart defect was rare since it was a trifecta of three heart conditions at the same time. At the age of 5, he had open heart surgery to repair the worst condition. The remainder of his childhood, he continued to see the cardiologist several times a year. With this exposure, he knew that he would pursue a career in medicine, though he took a very non-traditional path to get there.

Dr. Sargent graduated from Metropolitan State University of Denver with a bachelor’s degree in Psychology. Once graduated he spent 8 years working as a law enforcement officer. During this time, he was a member of the SWAT team and was a Field Training Officer(FTO). He also learned an extensive amount about community and the importance of having close relationships with the community. Throughout his time as a police officer, he continued to aspire to be a doctor, but with a minor tweak due to his love for animals. In 2009, he decided to take the leap.  Dr. Sargent returned to Metro State and completed 1.5 years of pre-requisites for veterinary school. He obtained his Doctor of Veterinary Medicine from Colorado State University in May 2015. Dr. Sargent has interests in surgery, internal medicine, dentistry and feline medicine. Along with dogs and cats, he has a passion for working with exotic animals including small mammals, birds, and reptiles.


Dr. Sargent moved to the Mount Vernon area in July 2017 after purchasing Highland Veterinary Hospital. Approximately a year later, he purchased Mountain View Veterinary Clinic.  The two clinics were subsequently combined and the Mountain View Veterinary Clinic name was chosen due to our view of Mount Baker and Dr. Sargent's passion for the outdoors.  As a Colorado native, Dr. Sargent was born and raised in Colorado and until moving to Washington has never lived outside Colorado.


Dr. Sargent moved to the Skagit Valley with his wife Cece, their children Alicia and Caleb. The family currently has a French Bulldog, Bivy, a Shih Tzu, Tenzing, 2 cats, Applesauce and Beans, a Shepherd mix, Lexie, a Labrador retriever, Jewels, and a flock of chickens named after various Star Wars Characters, Princess Layer, Kilo hen, Hen Solo, Luke Skysquaker and Obi-wan Henobi. 


Dr. Sargent is an avid rock climber. He loves climbing the Colorado 14ers and to date has climbed 10 of the 53, with the goal of climbing all 53. Now that he is living in Washington he and his wife have to summited Mount Baker and plan on sumiting Mount Rainier, with strong aspirations to head north to try to summit Mount Denali in Alaska. Dr. Sargent also enjoys hiking, snowboarding, cycling, running, camping, kayaking and pretty much anything outdoors with his family.


Dr. Marcie Mullen was born and raised on her family's 6th generation farm in Lyman, WA. She spent much of her childhood wading through rivers and streams to the perfect fly fishing hole, backpacking all over the North Cascades and Mount Baker wilderness, and running local trails. Summer jobs included dump truck driving and heavy equipment operator, as well as log choke setter and Idaho Giant salamander “catcher” for a graduate school program.


After graduating from Sedro-Woolley High School, Dr. Marcie attended Central Washington University – where she served as captain for the cross-country and track and field teams. She graduated summa cum laude with a Bachelor's of Science in Biology from CWU, and magna cum laude from Oregon State University’s College of Veterinary Medicine in 2013.

Dr. Marcie moved back home to the Skagit Valley soon after graduation to join a busy mixed-animal practice. While she is most comfortable with small animals and backyard chickens, she is excited to work with exotics again. Her interests include dentistry, internal medicine, geriatric medicine, pain management, and dermatology. 

When not in the office, you can usually find Dr. Marcie and her husband outside with their young son and daughter - hiking, fishing, biking, running, shooting, and gardening. Dr. Marcie is also well known for sewing some fairly elaborate Halloween costumes for her kids – and regularly flooding the house with smoke from her attempts at cooking. 


Dr. Marcie’s family also includes the loveable retired service Lab, Chief; a Golden Retriever rescue, Diesel; a crazy young Heeler, JoJo; and Miss Puffles the Destroyer – their friendly kitty. The family is constantly adding something to their brood, most recently chickens and ducks, and a variety of fish. 


Dr. Marcie is thrilled to join the Mountain View Veterinary Clinic family, and is excited to provide excellent care to your pets!
