Hi I’m Michelle! I’m a certified veterinary assistant and bring eight years of experience with me.

Christie Medford

Hopital Manager, Lead Client Service Representative

I came to Lakewood Vet. Hospital in 1998, 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 2 beautiful girls, and rescued multiple dogs and fish.  Now I'm back at Lakewood Veterinary Hospital to enjoy all the cute pets that come in. My passion is in the animal industry and I strive to help the practice here at Lakewood Veterinary Hospital to continue in growing.

When I'm not here I'm either hiking, kayaking, fishing, hanging with family or playing with my girls.

I have been in the veterinary field since 2016, working at different clinics in Colorado Springs and the Denver area.  I am originally from California but have made a home here in Colorado.  I am very excited to be working with the Lakewood Veterinary family and look forwarding to meeting all of the furry friends that come through our doors.
During my off time I like to go hiking, fishing, going on road trips or spending time with my own fluff ball at home, an orange kitty named Chunky.
