About Our Casper Veterinary Team

about the westside animal hospital in casper

Our Casper veterinary team has a combined 20+ years of experience working with dogs, cats, horses, and other animals. We're led by Dr. Doug Johannessen and Dr. Laura Johannessen, who both have had years of research, academic study, and clinical practice in California and Wyoming. Lifelong animal lovers, Dr. Doug and Dr. Laura are honored and pleased to be able to serve their community with the best of what veterinary medicine has to offer. 

Our team also has a number of friendly and extremely knowledgeable people including veterinary technicians, veterinary assistants, and kennel assistants to help streamline our services. Our number one priority is to make sure you and your animal feel as welcome and as comfortable as possible while in our care. 

To ensure that we are doing the best possible job, we've even hired a hospitality specialist named Nopey, the Johannessen's mixed rescue dog who loves to play with other boarding dogs and welcome every pet and pet owner with a wagging tail.
