Meet Our Doctors

  • Dr.
    Cor VanderWel, DVM

    Dr. Cor developed a love for science & animals while growing up on a farm in southern Wisconsin. He did his pre-vet work at Dordt College and then graduated from Iowa State College of Veterinary Medicine in 1987. Fillmore Veterinary Hospital was founded by Dr. Merle Watts in 1956, and after being here a year, Dr. Cor then bought him out at the end of 1988 and became the sole owner. Dr. Cor loves animals & is fascinated with how they work.  He is also a people-person, and being a small animal practitioner allows him to do both at the same time. Dr. Cor met his wife, Brenda in college and they were married in 1985. She is a Physician’s Assistant at a local family practice.  They have 3 children who are in their 30’s; two are physicians and one is a mechanical engineer. They now have 5 grandchildren and thoroughly enjoy their role as grandparents for these little people. His other interests besides medicine include getting together with family & friends, staying active in his church, reading adventure fiction and anything outside; working around the house, jogging, tandem biking, and hiking. He loves living here in Colorado & is thankful every day for health, family & friends, work, and the beautiful state we live in.

  • Dr.
    Karen Ricketts, DVM

    Dr. Karen Ricketts began her career in veterinary medicine at sixteen as a kennel caregiver at another busy veterinary practice and returned there as a veterinarian after graduating from Colorado State University in 1988. Dr. Ricketts came to Fillmore Veterinary Hospital in July 2016 and feels it is a perfect fit. Dr. Ricketts is owned by Bonzai, a black and white cat, but she also shares her life with two German Shepherd mix dogs and three other cats. Her two adult sons live in Denver without their cats and dogs. 

    In her free time, Dr. Karen Ricketts enjoys riding adventures on her horse.

  • Dr.
    Jesse Webb, DVM

    Dr. Jesse Webb is originally from the Gulf Coast of Florida, earned his DVM at St. Matthew's University in Grand Cayman, and previously practiced veterinary medicine in Southeast Alaska and Montana before moving to Colorado in May of 2014. He enjoys challenging internal medicine cases, soft tissue surgery, exotic animal medicine, and dentistry; however, his true passion in veterinary medicine is ultrasonography.

    Outside of work he enjoys hiking and exploring with his wife Melissa and dog Louie as well as relaxing around the house with their three cats, Ukie, Cece, and Lucille, watching baseball. The small amount of time left over is devoted to an occasionally successful attempt to trick a fish into believing a metal hook covered with a few hairs and feathers is an edible insect.

  • Dr. Connie Lee, DVM

    Born and raised in California, Dr. Lee attended UC Davis with a Bachelors in Animal Science, earned her DVM at St. George's University in Granada and finished her education at the University of Pennsylvania. 

    For the last ten years she worked in Michigan where she enjoyed treating dogs, cats, and exotic animals. A great opportunity came along that brought her family back west in the summer of 2022. 

    When she is not working, she is spending time with her husband, two kids, and two dogs. They love to explore the outdoors, enjoy new cuisines and the occasional musical theatre.
