    I came to Lakewood Vet. Hospital in 1999, but left in 2004 to pursue a degree in Biology. While I've been gone I married my wonderful husband Tim, gave birth to my beautiful girl Breana in May of 2010, and adopted two puppies named Skyy that's a 6 year old Weimeriner and Blood Hound Mix and Moose that's a Yellow Lab. Now I'm back at Lakewood Veterinary Hospital to enjoy all the cute pets that come in.

  • Madison

    Client Representative
    I entered the veterinary world looking for a career change and instantly knew this is what I was meant to do. I had worked at a veterinary clinic prior to Lakewood Veterinary Hospital and feel that LVH is the perfect fit for me. When I am not at the clinic you can find me in the mountains hiking, rock climbing, camping – you name it! I currently have a kitty named Fynn and a German Shepherd named Echo (who you will often find accompanying me on all my adventures.) I now want to further my education and pursue a lasting career with our four legged pals.
