  • Mary Thomas, DVM

    Dr. Mary Thomas graduated from the Washington State University College of Veterinary Medicine with honors in 1984. Growing up in Prosser she took her own pets to the Prosser Animal Hospital and began her career working there for Dr. Douglas Jackson. Originally this was a mixed practice which included veterinary care for horses and cattle. She and Dr. Sue Wedam purchased the practice in 1987. Dr. Wedam is now head of the veterinary technician program at Yakima Valley Community College.

    Dr. Mary loves the people and town of Prosser and cannot imagine living anywhere else! Veterinary medicine has been her passion since the age of three and she feels blessed to have been able to fulfill this dream. Her favorite part of practice is surgery and being able to truly make a difference for people and their pets. She and her staff are working hard to provide the pets of Prosser with high quality, compassionate medical care.

    Dr. Mary currently shares her home with her husband and two younger children, as their older two children are in college. Many pets make for a happy, if not always clean, home! She enjoys working in the dirt, skiing, needlework, scrapbooking, camping, and all the kids' activities. Dr. Mary is convinced that teaching ourchildren to love and care for a pet will make them better members of our society.

  • Celesté Lynn, DVM

    Celesté Lynn is one of Prosser Animal Hospital’s two full time veterinarians. She has been with us since 2009. Dr. Lynn supports Prosser Animal Hospital in the diagnosis and prevention of infectious disease, internal medicine, anesthesia and surgery, radiology, and dentistry. Dr. Lynn is licensed to practice veterinary medicine in the state of Washington and is licensed to issue health certificates for the transport of animals. Dr Lynn continually seeks continuing education opportunities through her memberships in the American Veterinary Medical Association and Washington State Veterinary Medical Association, as well as the online Veterinary Information Network and others.

    Dr. Lynn graduated with her Doctor of Veterinary Medicine degree from Washington State University’s College of Veterinary Medicine. Prior to medical school, she earned her Bachelor’s of Zoological Science from Washington State University.

    Dr. Lynn knew she wanted to be a veterinarian since she was four years old, living on her family’s hobby farm outside the city limits of Moses Lake, Washington. She grew up with sage brush, cheat grass, all kinds of pets and livestock, and loved every minute of it! She moved to Prosser shortly after graduation firstly because the staff at Prosser Animal Hospital impressed her not only with their competence and love for animals, but also with their congeniality and cohesiveness as a team. She loves Prosser’s small town atmosphere, quiet neighborhoods, and warm weather.

    Dr. Lynn is married to a geologist, with whom she loves to cook, go backpacking, berry-picking, and camping. Dr. Lynn is also an avid reader, so if you have any great suggestions for hiking trails or good literature, be careful not to mention it in an exam room, because she may become very distracted!

    Dr. Lynn and her husband have a son, Malcom, who is also becoming quite an animal lover! They also have two loveable, friendly female dogs, both of which were born in the summer of 2009. Atlas is an ultra-intelligent, emotional, hyper Border Collie cross who is still trying to master the difficult art of combining cuddling and wiggling. Atlas is quite independent, yet loyal and eager to please; she loves to run, jump, and explore. Atlas was named after the book Atlas Shrugged, by Ayn Rand. Vega is an easy-going, ALWAYS happy, fearless German Shorthair/Labrador cross. Vega’s favorite things include breakfast, toys, licking people, getting wet, dinner, and running. Vega’s name means “spirited,” but may soon mean “always hungry.”
