Hi! My name is Shannon. I started working at Annabessacook Veterinary Clinic in September 2021 after making a difficult decision to leave the Healthcare field after 10 years. I have always been passionate about taking care of others so transitioning to pet care has been a really wonderful change for me! I am the wife of a Marine named Evan and together we have three wonderful boys; Brady, Owen and Levi. We all love to hunt, fish and go to The Forks or Moosehead Lake region as often as possible! When I am not at work or up North you can most likely find me on the sidelines at our boys football and baseball games, probably cheering the loudest. We have two labrador retrievers named Bitsy and Finn. They are brother and sister. We also have two cats named Phil and Lil who are also brother and sister. It’s quite the crew!
