  • Jennifer Mead, N.D.

    Naturopathic Practitioner

    Dr. Jennifer Mead is a 4th generation physician but the first to pursue her degree in Naturopathic Medicine, graduating from Southwest College of Naturopathic Medicine in 2008. She is a native of South Louisiana where her roots are buried and her love of people and good times was nurtured. “You can take the girl out of the South but you cannot take the South out of the girl...” Although Dr. Jenn is thrilled to be raising her family in Wichita and officially a Wichitian, she loves sharing her Cajun heritage, traditions and hospitality here in the Midwest!

    Dr. Jenn’s goal as doctor is to partner with the patient where they are on their health journey and guide them along the path to uncovering all the obstacles in the way and discovering their own incredible power to heal themselves. In other words, as Doctor she acts as the ‘Medical Detective’ to understand the unique makeup of the patient, and to teach and share the tools to resolve the health concerns of the patient. Dr. Jenn has had over a decade of experience working with nearly all medical conditions, from the very simple cases to the severely complex conditions. It is not uncommon for her to successfully partner with those that no other doctor could “figure out.” Her favorite patients to partner with are those who have concerns regarding imbalanced hormones, metabolic conditions, obesity, chronic infections, gastrointestinal disturbances, skin conditions and allergies and autoimmunity. Dr. Jenn likes to gather a lot of objective information through laboratory testing to understand as much as she possibly can about the patient’s current state of health, however, the laboratory testing is not always a necessity. She is a big believer in what she learned during her schooling: “If you just listen to the patient, they will tell you the diagnosis.” Dr. Jenn views her career as a calling and not just a job and is thrilled to be part of the team here at VIS Clinic.

    When she is not at working with patients, Dr. Jenn is spending time with her husband and 3 children who keeps her very busy but despite the busyness she is always working hard to “walk the talk” by enjoying activity, healthy eating and much needed quiet time!

  • Marsha McCray, RN

    Marsha has been a licensed nurse since 1973, and is certified in auriculotherapy, (pain management by treating points on the ear). Marsha's background includes IV nutrient therapy, auricular pain management, and hospital nursing.
    “I enjoy helping people learn how to improve their health.”

  • Jan Revard, B.S.

    Jan has a Bachelor of Science in Biochemistry and spent seven years in research, five of them in Cancer research at an integrative medical facility. The past 6 years have been spent in patient and public relations in a holistic medical environment.
    “I love the personal contact with our patients.”

  • Angela Krier

    Angela has been married to Dr. Chad Krier for 16 wonderful years and they have four beautiful girls. She enjoys spending time with family and friends.
