Our Story

The Pet Wellness Network is a group of privately owned veterinary hospitals with a commitment to high quality medical care and exceptional customer service.  We believe that every neighborhood animal hospital is unique and tailored to that community, not a corporate practice that is the same in Alaska as it is in New York City. 

Founded by Dr. Don Costlow, the Pet Wellness Network strives to tailor each practice to the needs of the local community and their pets.  We value long term team members from doctors to support staff, allowing us to develop relationships with generations of families and their faithful companions.

The Pet Wellness Network team works 24 hours a day to improve the quality of life for every pet and every pet’s family.  We are committed to veterinary excellence for our patients and value for our clients.  We promise to serve you with respect, integrity, and compassion.
